Development of acute hydrops in eye with infectious keratitis: A case report. Am J Ophthalmol Case Rep 2024; 34:102045. [PMID: 38559364 PMCID: PMC10979013 DOI: 10.1016/j.ajoc.2024.102045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 02/09/2024] [Accepted: 03/12/2024] [Indexed: 04/04/2024] Open
Abstract
Purpose To determine the characteristics of an eye that developed acute hydrops while being treated for infectious keratitis. Observation A 35-year-old man presented with pain and blurred vision in his left eye. He had undergone cataract surgery seven years earlier and was being treated for poorly controlled atopic dermatitis. The decimal best-corrected visual acuity (BCVA) of the left eye was 0.01. Slit-lamp microscopy showed conjunctival injection, corneal opacification, and a corneal ulcer. The patient was diagnosed with infectious keratitis and was treated with topical and systemic antibiotics. During the hospitalization, the patient was noted to rub his eyes frequently and vigorously. Five days after the first visit, the cornea protruded markedly, and the stroma surrounding the ulcerated area was edematous. These findings led to a diagnosis of acute hydrops.Penetrating keratoplasty was performed to prevent corneal perforation. Histopathological study of the excised cornea showed stromal edema, infiltration of leukocytes, and a tear in Descemet's membrane. Unfortunately, the patient developed endophthalmitis the day after the surgery. The anterior chamber was irrigated with antibiotics, and antibiotics were also injected into the vitreous. The endophthalmitis gradually subsided, and two years after the surgery, the patient's decimal BCVA had improved to 0.6. Conclusion and importance Vigorous eye rubbing in cases of infectious keratitis can induce acute hydrops, and timely surgical intervention is recommended.

Case of acute retinal necrosis with rapid progression to proliferative vitreoretinopathy: A case report. Medicine (Baltimore) 2024; 103:e38150. [PMID: 38758916 PMCID: PMC11098224 DOI: 10.1097/md.0000000000038150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 04/16/2024] [Indexed: 05/19/2024] Open
Abstract
RATIONALE Acute retinal necrosis (ARN) was first reported in 1971 by Urayama et al as an acute uveitis accompanied by retinal arteritis and white retinal lesions in the peripheral retina that can progress to a rhegmatogenous retinal detachment (RRD). We have experienced a case of ARN that, unlike the common developmental course to an RRD associated with ARN, progressed to proliferative vitreoretinopathy (PVR) involving the entire retina in 2 days. The purpose of this report is to present our findings in the case of ARN with an atypical rapid time course. PATIENT CONCERNS The patient was a 56-year-old woman who was treated for uveitis of unknown origin by her primary care physician. She was referred to our hospital because of a worsening of the fundus findings. DIAGNOSIS Fundus examination in our hospital revealed vitreous opacities in the right eye, yellowish-white lesions extending around the retina, and some retinal hemorrhages. Because the retinal changes suggested ARN, we performed a polymerase chain reaction of the anterior atrial fluid and detected varicella-zoster virus. Then, the diagnosis of ARN was confirmed, and treatment was begun. At 1 month and a half after beginning the treatment, focal retinal traction was observed in the right fundus. Two days later, a circumferential PVR and a total retinal detachment were detected. INTERVENTIONS We then performed vitrectomy with an encircling buckle and a silicone oil tamponade. OUTCOMES Our examination 6 months postoperatively showed that the retina was attached and the BCVA was 20/200. LESSONS Our findings of a case of ARN showed that the progression from a local vitreous traction to a full circumferential PVR can develop in 2 days.

Nationwide epidemiologic survey on incidence of macular dystrophy in Japan. Jpn J Ophthalmol 2024; 68:167-173. [PMID: 38568448 DOI: 10.1007/s10384-024-01060-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Accepted: 01/31/2024] [Indexed: 05/12/2024]
Abstract
PURPOSE The aim of this study was to estimate the number of patients in Japan who had visited an ophthalmologist for macular dystrophy of various types, including Best vitelliform macular dystrophy (BVMD), Stargardt disease, occult macular dystrophy (OMD), cone (-rod) dystrophy, X-linked retinoschisis (XLRS), and central areolar choroid dystrophy (CACD). STUDY DESIGN Nationwide epidemiologic survey METHODS: Questionnaires were distributed to 965 major facilities, including all the university hospitals in Japan. The aim of the questionnaire was to determine the number of patients with each type of macular dystrophy who had visited an outpatient clinic during the past 5 years (January 2015 to December 2019). RESULTS Over 70% of the patients were diagnosed and followed up at university hospitals. The estimated annual number of newly diagnosed cases was as follows: 55.3 for BVMD, 36.7 for Stargardt disease, 35.8 for OMD, 160.6 for cone (-rod) dystrophy, 31.0 for XLRS, 29.8 for CACD, and 174.1 for other types of macular dystrophy. The total number of patients with macular dystrophy diagnosed and followed at major institutions was estimated to be 6651. CONCLUSION This was the first nationwide survey of macular dystrophy in Japan and provided an approximate number of affected patients. The diagnosis of macular dystrophy is primarily carried out at facilities with affiliated specialists, such as university hospitals. By examining the incidence of multiple diseases simultaneously, we were able to compare the incidence of each type of macular dystrophy.

Abstract
PURPOSE To determine the mechanism for the development of segmental granular lesions along the retinal vessels in eyes with acute retinal necrosis. METHOD This was a retrospective analysis of the medical records of three eyes of three patients who were diagnosed with acute retinal necrosis that had atypical segmental granular lesions aligned along the retinal vessels. RESULTS The segmental granular lesions were present on the retinal arteries and veins throughout the retina. Optical coherence tomography showed that the granular lesions protruded into the vitreous cavity. Histopathologic examinations confirmed that the lesions were made up of lymphocytes. CONCLUSION We suggest that the granular lesions were formed by a mechanism similar to that of HTLV-1-associated uveitis. We also found that the granular lesions disappeared soon after vitrectomy.

Case of persistent corneal epithelial damage after cataract surgery leading to diagnosis of vitamin A deficiency. Doc Ophthalmol 2024; 148:121-128. [PMID: 38265517 DOI: 10.1007/s10633-023-09963-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 12/21/2023] [Indexed: 01/25/2024]
Abstract
PURPOSE To report our findings of reduced full-field electroretinograms (ff-ERGs) and abnormal optical coherence tomographic (OCT) images in a patient with poor visual acuity after cataract surgery who was eventually diagnosed with vitamin A deficiency (VAD). METHODS This was a clinical study of a patient who complained of blurred vision after cataract surgery. To determine the cause of the reduced vision, we recorded full-field electroretinograms (ff-ERGs) to determine the scotopic and photopic status of the retina. We also performed optical coherence tomography to assess the changes in the retinal structure. Serological tests were performed. RESULTS A 74-year-old man presented with persistent corneal epithelial damages and reduced vision that developed after conventional cataract surgery. OCT showed an interrupted ellipsoid zone, and fundus autofluorescence (FAF) showed a severe hypofluorescence in the retina of the left eye. The scotopic ff-ERGs were severely reduced, and the photopic ff-ERGs were mildly reduced. Serological examinations revealed a vitamin A concentration < 7 IU/dL (normal, 97-316 IU/dL). Based on these findings, we diagnosed the patient with VAD and started treatment with oral vitamin A supplements. After three months, his visual acuity, ff-ERGs, and OCT findings recovered to normal levels. The amplitudes and implicit times of the RETeval flicker ERGs increased to be within the normal range, and the hypofluorescence of the left eye disappeared. The length of the photoreceptor outer segments increased after the vitamin A supplementation. CONCLUSION Our findings indicate that the ERGs are helpful for diagnosing patients with VAD associated with persistent corneal epithelial damages.

Genetic and Clinical Features of ABCA4-Associated Retinopathy in a Japanese Nationwide Cohort. Am J Ophthalmol 2024; 264:36-43. [PMID: 38499139 DOI: 10.1016/j.ajo.2024.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 03/01/2024] [Accepted: 03/11/2024] [Indexed: 03/20/2024]
Abstract
PURPOSE To clarify the genetic and clinical features of Japanese patients with ABCA4-associated retinopathy. DESIGN Retrospective, multicenter cohort study. METHODS Patients with retinal degeneration and biallelic ABCA4 variants were recruited from 13 different hospitals. Whole exome sequencing analysis was used for genetic testing. Comprehensive ophthalmic examinations were performed on matched patients. The primary outcome measure was identifying multimodal retinal imaging findings associated with disease progression. RESULTS This study included 63 patients: 19 with missense/missense, 23 with missense/truncation, and 21 with truncation/truncation genotypes. In total, 62 variants were identified, including 29 novel variants. Six patients had a mild phenotype characterized by foveal-sparing or preserved foveal structure, including 4 with missense/missense and 2 with missense/truncation genotypes. The p.Arg212His variant was the most frequent in patients with mild phenotypes (4/12 alleles). Clinical findings showed a disease duration-dependent worsening of the phenotypic stage. Patients with the truncation/truncation genotype exhibited rapid retinal degeneration within a few years and definite fundus autofluorescence imaging patterns, including hyper autofluorescence at the macula and few or no flecks. CONCLUSIONS Our results indicate that missense/missense or missense/truncation genotypes, including the p.Arg212His variant, are associated with a relatively mild phenotype. In contrast, the truncation/truncation genotype causes rapid and severe retinal degeneration in Japanese patients with ABCA4-associated retinopathy. These data are vital in predicting patient prognosis, guiding genetic counseling, and stratifying patients for future clinical trials.

Reliability of Binocular Esterman Visual Field Test in Patients with Glaucoma and Other Ocular Conditions. Diagnostics (Basel) 2024; 14:433. [PMID: 38396473 PMCID: PMC10887531 DOI: 10.3390/diagnostics14040433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 02/08/2024] [Accepted: 02/14/2024] [Indexed: 02/25/2024] Open
Abstract
The binocular Esterman visual field test (EVFT) of 120 points was the first method to quantify the defects in the binocular visual field. It is used in many parts of the world as a standard test to determine whether an individual has the visual capabilities to drive safely. In Japan, it is required for the grading and issuance of visual disability certificates. The purpose of this study was to determine the reliability of the EVFT results. We studied 104 patients who had undergone the binocular EVFT at Mie University Hospital. Their mean age was 68.0 ± 11.4 years, and the best-corrected visual acuity of the better eye was 0.18 ± 0.38 logMAR units. The EVFT was performed twice on the same day, and the results of the first and second tests were compared. The mean Esterman scores for the first and second test were 89.3 ± 30.5 and 89.1 ± 30.2, respectively, and the test times were 338.9 ± 86.8 and 336.7 ± 76.4 s, respectively. The differences were not significant (p = 0.69 and p = 0.33). In the Bland-Altman analyses (second-first test) of the Esterman scores, the mean difference was 0.38 without significant fixed errors (p = 0.20) or proportional errors (p = 0.27). The limits of agreement within the 1.96 standard deviation were -8.96 to +9.45 points. The agreement rate for the most peripheral 24 test points was significantly lower than the agreement rate for the other 96 test points (p < 0.01). The agreement rate of the upper visual field was significantly lower than that of the lower field (p < 0.01). The overall reliability rate of the EVFT is acceptable, but the peripheral and upper test points have relatively low reliability rates. These findings are important for interpretations of the EVFT results.

Distinct Clinical Effects of Two RP1L1 Hotspots in East Asian Patients With Occult Macular Dystrophy (Miyake Disease): EAOMD Report 4. Invest Ophthalmol Vis Sci 2024; 65:41. [PMID: 38265784 PMCID: PMC10810149 DOI: 10.1167/iovs.65.1.41] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 12/20/2023] [Indexed: 01/25/2024] Open
Abstract
Purpose To characterize the clinical effects of two RP1L1 hotspots in patients with East Asian occult macular dystrophy (OMD). Methods Fifty-one patients diagnosed with OMD harboring monoallelic pathogenic RP1L1 variants (Miyake disease) from Japan, South Korea, and China were enrolled. Patients were classified into two genotype groups: group A, p.R45W, and group B, missense variants located between amino acids (aa) 1196 and 1201. The clinical parameters of the two genotypes were compared, and deep learning based on spectral-domain optical coherence tomographic (SD-OCT) images was used to distinguish the morphologic differences. Results Groups A and B included 29 and 22 patients, respectively. The median age of onset in groups A and B was 14.0 and 40.0 years, respectively. The median logMAR visual acuity of groups A and B was 0.70 and 0.51, respectively, and the survival curve analysis revealed a 15-year difference in vision loss (logMAR 0.22). A statistically significant difference was observed in the visual field classification, but no significant difference was found in the multifocal electroretinographic classification. High accuracy (75.4%) was achieved in classifying genotype groups based on SD-OCT images using machine learning. Conclusions Distinct clinical severities and morphologic phenotypes supported by artificial intelligence-based classification were derived from the two investigated RP1L1 hotspots: a more severe phenotype (p.R45W) and a milder phenotype (1196-1201 aa). This newly identified genotype-phenotype association will be valuable for medical care and the design of therapeutic trials.

A comparative study of the CT effective dose in whole-body 18F-FDG PET/CT for arm-raised position and arm-lowered position. Radiography (Lond) 2024; 30:416-421. [PMID: 38181465 DOI: 10.1016/j.radi.2023.12.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 11/29/2023] [Accepted: 12/19/2023] [Indexed: 01/07/2024]
Abstract
INTRODUCTION This study aimed to investigate and compare the effective dose (ED) delivered by computed tomography (CT) in whole-body positron emission tomography/CT (WB-PET/CT) scans between patients positioned with their arms-raised and those with their arms-lowered during the scan on a large population. METHODS The retrospective study involved 785 oncology patients who underwent WB-PET/CT scans with 18F-FDG between January and June 2019. Exclusion criteria were applied, resulting in a final analysis of data from 732 adult patients. All of the patients were measured height and weight, and the ED from CT in WB-PET/CT was estimated using the dose length product value and a conversion factor. Statistical analyses were conducted to explore relationships between factors and the ED. Linear regression analysis was performed to investigate connections between weight and ED, and height and ED. Multiple linear regression was used to predict ED based on sex, weight, and arm position. RESULTS The arm-lowered group had a higher ED than the arm-raised group, and the median dose was 1.1 times higher in the arm-lowered group. The difference in ED between the two groups was found to be greater with higher body weight. Arm-position (β = 0.460), sex (β = -0.190), and weight (β = 0.057) were significant predictors of ED. CONCLUSION This study demonstrated that arm position, sex, and weight were significant factors influencing the ED from CT scans in WB-PET/CT. IMPLICATIONS FOR PRACTICE The research underscores the importance of considering these factors when evaluating radiation exposure in clinical practice, particularly for patients undergoing WB-CT imaging. These findings contribute to a better understanding of the radiation dosimetry associated with different patient positions during WB-PET/CT scans.

Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial. Lancet Diabetes Endocrinol 2024; 12:39-50. [PMID: 38061371 PMCID: PMC7615591 DOI: 10.1016/s2213-8587(23)00321-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Intraocular Inflammation Secondary to Intravitreal Brolucizumab Injection for Neovascular Age-Related Macular Degeneration in a Patient with Cognitive Impairment. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1856. [PMID: 37893574 PMCID: PMC10608434 DOI: 10.3390/medicina59101856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 10/15/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023]
Abstract
Background and Objectives: Brolucizumab (IVBr) is a recently introduced anti-vascular endothelial growth factor (anti-VEGF) which has been found to be very effective in treating neovascular age-related macular degeneration (nAMD). We reported our findings in a case of nAMD that developed intraocular inflammation (IOI) after IVBr injections. Materials and Methods: A 79-year-old man was referred to our hospital complaining of reduced vision in both eyes of one-month's duration. His decimal best-corrected visual acuity (BCVA) was 0.9 in the right eye and 1.0 in the left eye. He was diagnosed with nAMD in the left eye and was treated with intravitreal aflibercept (IVA). Despite the three-monthly IVA injections, the serous retinal pigment epithelial detachment (PED) and subretinal fluid (SRF) remained, and the VA gradually decreased to 0.1. Because of the patient being refractory to aflibercept treatment, we switched to 3-monthly IVBr injections. The BCVA gradually improved to 0.3 and optical coherence tomography (OCT) showed an absence of the serous PED and SRF. Three weeks after his third IVBr, he returned to our hospital with a complaint of reduced vision in his left eye that he first noted two weeks earlier. Our examination of the left eye showed signs of IOI mainly in the anterior chamber. The inflammation improved with topical steroids but the treatment of the IOI was delayed for two weeks. The patient was instructed that it was important to begin the treatment as soon as the symptoms of IOI developed. We then performed the Mini-Mental State Examination (MMSE), and his score indicated that he had cognitive impairment. Conclusions: We concluded that before beginning IVBr treatment in nAMD patients, a careful assessment must be made of the cognitive status of the patient.

[PMID: 37295608 DOI: 10.1016/j.oret.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 06/01/2023] [Accepted: 06/01/2023] [Indexed: 06/12/2023]
Abstract
PURPOSE Neovascular age-related macular degeneration (nAMD) is classified into typical AMD (tAMD), polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP). This study investigated clinical features of the 3 subtypes and visual outcome associated with treatment regimens in a large cohort of patients with nAMD in a clinical setting. DESIGN Retrospective multicenter cohort study. PARTICIPANTS Five hundred patients with treatment-naive nAMD (268 tAMD, 200 PCV, and 32 RAP) initiated with anti-VEGF agents and followed for 1 year. METHODS Medical records were reviewed to extract demographic data, best-corrected visual acuity at baseline and 1 year after treatment initiation, spectral-domain OCT findings, baseline fellow eye condition, systemic factors, treatment strategies, and number of intravitreal injections in the first year. MAIN OUTCOME MEASURES Primary outcome measures were anti-VEGF treatment strategy (ranibizumab or aflibercept, anti-VEGF regimen, concomitant photodynamic therapy, drug switch), best-corrected visual acuity at 1 year, and factors associated with visual acuity. RESULTS Patients with RAP were significantly older, were more commonly women, and had more macular lesions in fellow eye than patients with tAMD and PCV. Smoking history and diabetes prevalence were not different among the 3 subtypes. Frequencies of subretinal fluid were higher and intraretinal fluid were lower in tAMD and PCV than in RAP, whereas serous pigment epithelial detachment and subretinal hemorrhage were higher in PCV than in tAMD and RAP. Choice of anti-VEGF agents and treatment regimens did not differ among 3 subtypes. The aflibercept-to-ranibizumab ratio was approximately 7:3. The mean number of injections in 1 year was 5.3 ± 2.4 in nAMD overall, which was significantly less in pro re nata (PRN) than in treat and extend (TAE) regardless of the anti-VEGF agent. Best-corrected visual acuity improved in all 3 subtypes, although it was not significant in patients with RAP. CONCLUSIONS This clinical study demonstrates that treatment regimens were similar in 3 subtypes and aflibercept was used in 70% of all patients. Approximately 5 injections were given in the first year regardless of the anti-VEGF agent, which was significantly less in PRN regimen than in TAE. Visual acuity improvement was observed after 1-year anti-VEGF therapy in all 3 subtypes, but was not significant in RAP.

One-Year Outcomes of Oral Treatment With Alga Capsules Containing Low Levels of 9-cis-β-Carotene in RDH5-Related Fundus Albipunctatus. Am J Ophthalmol 2023; 254:193-202. [PMID: 37343743 DOI: 10.1016/j.ajo.2023.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 06/13/2023] [Accepted: 06/13/2023] [Indexed: 06/23/2023]
Abstract
PURPOSE This study aimed to clarify the effect of 1-year oral treatment with 9-cis-β-carotene-rich alga Dunaliella bardawil (Dunaliella supplementation) using full-field electroretinography (ERG) in patients with RDH5-related fundus albipunctatus (FAP). DESIGN Prospective, interventional case series. PARTICIPANTS The study included 12 patients (23 eyes) with RDH5-related FAP. METHODS Twelve patients (23 eyes) with RDH5-related FAP received Dunaliella supplementation (total daily dose of β-carotene was 74.0 mg, comprising 28.4 mg 9-cis-β-carotene and 45.6 mg all-trans-β-carotene at a ratio of 1:1.6) for 1 year and underwent ophthalmic examinations, including full-field ERG at baseline, 3 months, and 1 year after the initial treatment. MAIN OUTCOME MEASURES The main outcome was changes in the amplitudes of responses of full-field ERG before and after treatment. A linear mixed-effects model was used to evaluate the adjusted mean difference between the amplitude of each response pretreatment and posttreatment. RESULTS Prolonged dark adaptation (DA) responses at 3 months revealed a significant impairment in the b-wave of DA 0.01 (adjusted mean difference, -34.7, 95% CI, -66.8 to -2.73, P = .041) and a-wave of DA 3.0 (-29.0, 95% CI, -50.6 to -7.41, P = .013) and DA 10.0 (-40.4, 95% CI, -67.8 to -13.0, P = .007), which were also observed at 1 year. Additionally, prolonged DA and light adaptation (LA) responses revealed statistically significant impairment at 1 year in the b-wave of DA 3.0 (-43.8, 95% CI, -82.9 to -4.78, P = .035), DA 10.0 (-59.7, 95% CI, -101.8 to -17.61, P = .009), LA 3.0 (-7.31, 95% CI, -13.6 to -1.04, P = .029), and LA 3.0 flicker (-7.53, 95% CI, -12.7 to -2.34, P = .007). CONCLUSIONS Our study results suggest that Dunaliella supplementation comprising low levels of 9-cis-β-carotene compared with those reported in a previous study (1:1 ratio) adversely affects ERG amplitudes in patients with RDH5-related FAP.

Occult Macular Dysfunction Syndrome: Identification of Multiple Pathologies in a Clinical Spectrum of Macular Dysfunction with Normal Fundus in East Asian Patients: EAOMD Report No. 5. Genes (Basel) 2023; 14:1869. [PMID: 37895218 PMCID: PMC10606510 DOI: 10.3390/genes14101869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 09/20/2023] [Accepted: 09/21/2023] [Indexed: 10/29/2023] Open
Abstract
Occult macular dystrophy (OMD) is the most prevalent form of macular dystrophy in East Asia. Beyond RP1L1, causative genes and mechanisms remain largely uncharacterised. This study aimed to delineate the clinical and genetic characteristics of OMD syndrome (OMDS). Patients clinically diagnosed with OMDS in Japan, South Korea, and China were enrolled. The inclusion criteria were as follows: (1) macular dysfunction and (2) normal fundus appearance. Comprehensive clinical evaluation and genetic assessment were performed to identify the disease-causing variants. Clinical parameters were compared among the genotype groups. Seventy-two patients with OMDS from fifty families were included. The causative genes were RP1L1 in forty-seven patients from thirty families (30/50, 60.0%), CRX in two patients from one family (1/50, 2.0%), GUCY2D in two patients from two families (2/50, 4.0%), and no genes were identified in twenty-one patients from seventeen families (17/50, 34.0%). Different severities were observed in terms of disease onset and the prognosis of visual acuity reduction. This multicentre large cohort study furthers our understanding of the phenotypic and genotypic spectra of patients with macular dystrophy and normal fundus. Evidently, OMDS encompasses multiple Mendelian retinal disorders, each representing unique pathologies that dictate their respective severity and prognostic patterns.

Abstract
PURPOSE We investigated potential predictive factors for visual prognosis in Japanese patients with endogenous endophthalmitis. DESIGN Retrospective observational multicenter cohort study. METHODS We examined the characteristics of 77 Japanese patients with endogenous endophthalmitis and performed statistical analyses of these real-world data. The primary endpoint was the identification of factors associated with visual prognosis. We examined differences between patients in the better vision and legal blindness groups at 12 weeks after treatment initiation. RESULTS The five risk factors for visual impairment at 12 weeks after treatment initiation were presence of pressure injuries, severe clinical symptoms (presence of eye pain and ciliary injection), pathogen identification, and poor best-corrected visual acuity at baseline. Staphylococcus aureus and fungus were associated with a better visual impairment outcome. CONCLUSIONS Endogenous endophthalmitis remains a severe ocular infection; however, it can be managed with rapid treatments, as well as other advances in medical knowledge and technology.

Comparisons of Clinical Characteristics and Surgical Outcomes of Epiretinal Membrane Foveoschisis to Typical Epiretinal Membrane. J Clin Med 2023; 12:4009. [PMID: 37373702 DOI: 10.3390/jcm12124009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 06/10/2023] [Accepted: 06/11/2023] [Indexed: 06/29/2023] Open
Abstract
Epiretinal membrane (ERM) foveoschisis is a recently proposed clinical entity. The purpose of this study was to compare the clinical characteristics and surgical outcomes of eyes with ERM foveoschisis to those of typical ERM. The medical records of all patients with ERM-related disorders examined between 2011 and 2020 were reviewed. ERM foveoschisis was defined by the clinical criteria proposed by an international panel of experts on ERMs. The background factors, clinical characteristics, and surgical outcomes of ERM foveoschisis were compared to those of typical ERM. Forty eyes with ERM foveoschisis were compared to 333 eyes with typical ERM. The percentage of women was significantly higher in the ERM foveoschisis group (92.5%) than in the typical ERM group (48.9%, p < 0.001). The central macular thickness (CMT) was significantly thinner in the ERM foveoschisis group (340 ± 110 μm) than in the typical ERM groups (476 ± 111 μm, p < 0.01). The degree of improvement in the best-corrected visual acuity (BCVA) three months after the surgery did not differ between the two groups (p = 0.59). These results suggest that the ERM foveoschisis is more likely to occur in women and that the prognosis after surgery is comparable to typical ERM.

Abstract
In this retrospective case series, we investigated factors associated with posterior capsule aperture (PCA) reclosure following neodymium-yttrium aluminum garnet (Nd:YAG) laser posterior capsulotomy. The study encompassed patients who underwent cataract surgery with intraocular lens (IOL) implantation or a combined vitrectomy, cataract surgery, and IOL implantation between 2009 and 2022. PCA reclosure was observed in 22 eyes of 17 patients: 45% (10 eyes) underwent the triple procedure, and 55% (12 eyes) received cataract surgery with IOL implantation. In our clinic, 14% of patients were given IOLs with a 4% water content, while 73% (13 eyes) of those experiencing PCA reclosure had IOLs with a 4% water content. The mean interval between Nd:YAG capsulotomies was notably shorter than that between the initial cataract surgery and the first Nd:YAG laser capsulotomy. We also identified five stages of PCA reclosure progression. In conclusion, IOL water content may be linked to PCA reclosure, and the time to recurrence is shorter with each successive reclosure. Further research is needed to verify these findings and uncover additional contributing factors.

Effects of Perfluorocarbon Use during Rhegmatogenous Retinal Detachment Surgery on Postoperative Outcomes. Ophthalmologica 2023; 246:219-226. [PMID: 37271123 DOI: 10.1159/000531342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Accepted: 05/22/2023] [Indexed: 06/06/2023]
Abstract
INTRODUCTION The aim of this study was to determine whether the use of perfluorocarbon liquid (PFCL) affects the rate of retinal re-attachments after an initial attachment by vitrectomy in eyes with rhegmatogenous retinal detachment (RRD). METHODS This was a retrospective, observational, multicenter study of 3,446 eyes registered in the Japanese vitreoretinal surgery treatment information database. Of these, 2,648 eyes had undergone vitrectomy as the first surgery for RRD. The re-attachment rates after the primary vitrectomy with or without PFCL were evaluated. In addition, the significance of factors affecting the re-detachments was determined by univariate and multivariate analyses. The measured outcomes were the rates of re-attachments after the primary vitrectomy with or without the use of PFCL. RESULTS A total of 2,362 eyes in the database were analyzed: 325 had and 2,037 did not have PFCL injected into the vitreous cavity during the vitrectomy. The rate of re-attachments was 91.5% in the PFCL group and 93.2% in the non-PFCL group (p = 0.46, χ2 test). Although there were several risk factors associated with the re-detachments in eyes without PFCL (p < 0.05, Welch's t tests, and Fisher's exact tests), they were not associated in eyes with PFCL use. However, multivariate analyses showed that there was no significant association between the use and the non-use of PFCL in the rate of re-detachments (β = -0.08, p = 0.46). CONCLUSIONS The use of PFCL during the initial vitrectomy for RRD does not affect the rate of re-attachments.

Abstract
PURPOSE To determine whether atrophy of the retinal pigment epithelium (RPE) in eyes with neovascular age-related macular degeneration (nAMD), which meets the criteria for the suspension of anti-vascular endothelial growth factor (anti-VEGF) treatment, is associated with anti-VEGF treatments. METHODS Twelve eyes of 12 patients with nAMD who began anti-VEGF treatment and were followed for 1 year after meeting the criteria for the suspension of anti-VEGF were studied. Six eyes of six patients were placed in the continuation group, and six eyes of six patients were placed in the suspension group. The RPE atrophic area at the time of the last anti-VEGF treatment was set as the baseline size and that at 12 months after the baseline (Month 12) was taken as the final size. A comparison of the expansion rate of RPE atrophy between the two groups was made by the square-root transformed differences. RESULTS The expansion rate of atrophy was 0.55 (0.43, 0.72) mm/year in the continuation group and 0.33 (0.15, 0.41) mm/year in the suspension group. This difference was not significant. (p = 0.29). CONCLUSIONS Suspension of anti-VEGF treatments in eyes with nAMD does not alter the expansion rate of RPE atrophy.

Abstract
Background and Objectives: Anti-vascular endothelial growth factor (anti-VEGF) therapy has become the first-line treatment for diabetic macular edema. However, it is still not clear whether anti-VEGF agents act on systemic blood vessels. The aim of this study is to determine whether a direct topical application or intravitreal injection of anti-VEGF will change the intestinal blood vessels of mice. Materials and Methods: C57BL/6 mice were laparotomied under deep anesthesia, and the blood vessels on the surface of the intestines were exposed, examined, and photographed through a dissecting microscope. Vascular changes were evaluated before and at 1, 5, and 15 min after the topical application of 50 µL of the different anti-VEGF agents onto the surface of the intestine (group S) or after the intravitreal injection (group V). The vascular density (VD) was determined for five mice in each group before and after 40 μg/μL of aflibercept (Af), or 25 μg/μL of bevacizumab (Be), or 10 μg/μL of ranibizumab (Ra) were applied. Endothelin-1 (ET1), a potent vasoconstrictor, was used as a positive control, and phosphate-buffered saline (PBS) was used as a control. Results: For group S, no significant changes were observed after PBS (baseline, 1, 5, and 15 min: 46.3, 44.5, 44.8, and 43.2%), Be (46.1, 46.7, 46.7, and 46.3%), Ra (44.7, 45.0, 44.7, and 45.6%), and Af (46.5, 46.2, 45.9, and 46.1%, repeated ANOVA) were applied topically. Significant decreases in the VD were observed after ET1 (46.7, 28.1, 32.1, and 34.0%, p < 0.05) was topically applied. For group V, no significant differences were observed for all anti-VEGF agents. Conclusions: The topical application or intravitreal injections of anti-VEGF agents do not cause a change in the VD of the intestinal vessels, which may be related to its safety.

Abstract
RATIONALE Multiple evanescent white dot syndrome (MEWDS) is characterized by multiple white dots in the posterior pole of the eye, but its diagnosis can be difficult in cases when the white dots are not visible. We report an atypical case of MEWDS that developed in pathologic myopia. PATIENT CONCERN A 42-year-old woman presented with floater and reduced and distorted vision in the right eye that she noted 3 days earlier. DIAGNOSIS The right eye was highly myopic at -17.0 diopters, and her decimal best-corrected visual acuity was reduced to 0.2 (20/100). Fundus examinations revealed no abnormalities other than myopic fundus changes and previous laser photocoagulation spots. However, fundus autofluorescence (FAF) showed multiple hyperfluorescent dots, and optical coherence tomography showed a high reflective lesion on the retinal pigmental epithelium at the fovea. Adjustments of the brightness and contrast of the conventional fundus images revealed white dots in the same location as the hyperfluorescent spots seen in the FAF images. We diagnosed her with MEWDS. INTERVENTIONS We treated her with systemic administration of 20 mg prednisolone and the dose of prednisolone was reduced by 5 mg every 4 weeks. OUTCOMES The optical coherence tomography and FAF findings gradually normalized, and 5 months later, her decimal visual acuity was restored to 1.0 (20/20). LESSONS It was suggested that white dots typical to MEWDS may not be evident in pathologic myopia, and FAF images and the brightness and contrast adjustment of fundus images were useful in the diagnosis of atypical MEWDS.

Abstract
The only approved retinal gene therapy is for biallelic RPE65 mutations which cause a recessive retinopathy with a primary molecular defect located at the retinal pigment epithelium (RPE). For a distinct recessive RPE disease caused by biallelic BEST1 mutations, a pre-clinical proof-of-concept for gene therapy has been demonstrated in canine eyes. The current study was undertaken to consider potential outcome measures for a BEST1 clinical trial in patients demonstrating a classic autosomal recessive bestrophinopathy (ARB) phenotype. Spatial distribution of retinal structure showed a wide expanse of abnormalities including large intraretinal cysts, shallow serous retinal detachments, abnormalities of inner and outer segments, and an unusual prominence of the external limiting membrane. Surrounding the central macula extending from 7 to 30 deg eccentricity, outer nuclear layer was thicker than expected from a cone only retina and implied survival of many rod photoreceptors. Co-localized however, were large losses of rod sensitivity despite preserved cone sensitivities. The dissociation of rod function from rod structure observed, supports a large treatment potential in the paramacular region for biallelic bestrophinopathies.

Abstract
PURPOSE We investigated potential risk factors for visual prognosis in Japanese patients with exogenous endophthalmitis. METHODS In this retrospective observational multicenter cohort study, risk factors for legal blindness at 12 weeks after treatment initiation were evaluated based on patient characteristics, initial BCVA, causative events, pathogens, ocular symptoms, duration from symptom onset to initial treatment, and selected treatments. RESULTS Overall, 23.1% of eyes developed legal blindness. The six risk factors for legal blindness were presence of eye pain, pathogen identification, poor BCVA at the initial visit, longer duration from symptom onset to initial treatment, type of causative event, and type of causative pathogen. Regarding the type of causative pathogen, coagulase-negative staphylococci was associated with a better visual impairment outcome. CONCLUSION Exogenous endophthalmitis remains a severe ocular infection; however, it can be managed with rapid treatment, as well as other advances in medical knowledge and technology.

Abstract
In biliary atresia (BA), efforts to prevent premature liver transplantation (LT) are aimed at early diagnosis, timing of Kasai-portoenterostomy (KPE), and centralization of care. This report presents the clinical picture, treatment strategies, and outcomes of BA patients with no previous treatment. A retrospective cohort study (Jan/2001 to Jan/2021) was conducted to evaluate the outcome of patients with BA referred to a single team. Study groups were: 1) Kasai-only group (K-only) n=9), 2) LT-only group (n=7), and 3) Kasai+LT group (K+LT) (n=23). Survival with native liver and overall survival were 22.9 and 94.8%, respectively, at 120 months of follow-up. There was no difference in age at KPE in the K-only group (46.8±21.8 days) vs K+LT (52.1±22 days), P=0.4. Ten (25.6%) patients were babies conceived through in vitro fertilization (IVF). Four IVF patients (40%) presented associated congenital heart disease vs 5 patients (17%) in the remaining group (P=0.14). Two of the IVF patients were premature (<37 weeks). Median maternal age at birth was 35 years (33 to 41 years). Excellent patient survival is expected for patients with BA with the available treatment strategies. IVF+BA was an unexpected prevalent association in this cohort, and further studies are required to better understand these findings.

Abstract
RATIONALE It is difficult to follow changes in the intraocular pressure (IOP) in glaucomatous eyes comprehensively because of the limited number of outpatient examinations. We report our findings in a case of normal tension glaucoma (NTG) in which frequent self-measurements of the IOP were used to evaluate the IOP-lowering effect of different medications. PATIENT CONCERNS A 50-year-old man with NTG had a nasal step visual field defect in his right eye and was being treated with 0.005% latanoprost (LAT) ophthalmic solution (XALATAN®). DIAGNOSIS The patient was diagnosed with NTG. INTERVENTIONS The patient had a mean IOP in the right eye of 10.9 ± 1.5 mm Hg (68 measurements in 1 month, Period A) during treatment with 0.005% LAT ophthalmic solution. During the second month (Period B), the mean IOP in the same eye was 9.8 ± 1.7 mm Hg (59 measurements) with treatment with a LAT and carteolol fixed combination (LCFC). And during the third month (Period C), the mean IOP was 7.4 ± 1.1 mm Hg (57 measurements) on the same right eye after the addition of brimonidine and brinzolamide fixed combination ophthalmic solution to the LCFC ophthalmic solution. OUTCOMES Comparisons of the IOPs between Periods A and B and between B and C showed that the reductions in the IOP were significant. CONCLUSION We conclude that frequent self-measurements of the IOP can determine that small changes of the IOPs are significant.

A Japanese boy with Bardet-Biedl syndrome caused by a novel homozygous variant in the ARL6 gene who was initially diagnosed with retinitis punctata albescens: A case report. Medicine (Baltimore) 2022; 101:e32161.

Abstract
PURPOSE Bardet-Biedl Syndrome (BBS) is an autosomal recessive systemic disorder characterized by retinitis pigmentosa, polydactyly, obesity, intellectual disability, renal impairments, and hypogonadism. The purpose of this study was to determine the ocular characteristics of a boy with BBS caused by a novel homozygous variant in the ARL6 (alternative named BBS3) gene who had been originally diagnosed with retinitis punctata albescens. METHODS This was an observational case study. The patient underwent ophthalmological examinations, electroretinography, and genetic analyses using whole-exome sequencing. RESULTS A 7-year-old boy was examined in our hospital with complaints of a progressive reduction of his visual acuity and night blindness in both eyes. There was no family history of eye diseases and no consanguineous marriage. Fundus examinations showed numerous white spots in the deep retina and retinal pigment epithelium. Fundus autofluorescence showed hypofluorescence consistent with these spots. Both the scotopic and photopic components of the full-field electroretinographies were non-detectable. Based on these clinical findings, this boy was suspected to have retinitis punctata albescens. Subsequent genetic testing using whole-exome sequencing revealed a novel homozygous variants in the ARL6/BBS3 gene (NM_001278293.3:c.528G>A, (p.Trp176Ter)). A systemic examination by the pediatric department revealed that this boy had a history of a surgical excision of polydactyly on his left foot when he was born, and that he was mildly obese. There were no prominent intellectual or gonadal dysfunctions, no craniofacial or dental abnormalities, no congenital heart disease, and no hearing impairment. He was then clinically and genetically diagnosed with BBS. CONCLUSION AND IMPORTANCE In children with night blindness and progressive visual dysfunction, it is important for ophthalmologists to consult clinical geneticists and pediatricians to rule out the possibility of systemic diseases such as BBS.

Genetic characterization of 1210 Japanese pedigrees with inherited retinal diseases by whole-exome sequencing. Hum Mutat 2022; 43:2251-2264. [PMID: 36284460 DOI: 10.1002/humu.24492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 09/18/2022] [Accepted: 10/21/2022] [Indexed: 01/25/2023]
Abstract
Inherited retinal diseases (IRDs) comprise a phenotypically and genetically heterogeneous group of ocular disorders that cause visual loss via progressive retinal degeneration. Here, we report the genetic characterization of 1210 IRD pedigrees enrolled through the Japan Eye Genetic Consortium and analyzed by whole exome sequencing. The most common phenotype was retinitis pigmentosa (RP, 43%), followed by macular dystrophy/cone- or cone-rod dystrophy (MD/CORD, 13%). In total, 67 causal genes were identified in 37% (448/1210) of the pedigrees. The first and second most frequently mutated genes were EYS and RP1, associated primarily with autosomal recessive (ar) RP, and RP and arMD/CORD, respectively. Examinations of variant frequency in total and by phenotype showed high accountability of a frequent EYS missense variant (c.2528G>A). In addition to the two known EYS founder mutations (c.4957dupA and c.8805C>G) of arRP, we observed a frequent RP1 variant (c.5797C>T) in patients with arMD/CORD.

Abstract
OBJECTIVES To describe a standardised subserosal layer dissection technique and evaluate its outcomes in canine laparoscopic cholecystectomy. MATERIALS AND METHODS Medical records of dogs undergoing laparoscopic cholecystectomy using the standardised subserosal layer dissection technique for the treatment of cholecystolithiasis, cholecystitis, and gall bladder mucocele at a single veterinary hospital from January 2015 to September 2021 were extracted. Operative time, subserosal layer dissection achievement rate, open conversion rate, and complication rate were evaluated. RESULTS Thirty-four dogs were included. The most common preoperative diagnosis was cholecystolithiasis (n=29). Operative time was 190 minutes (range: 110 to 330 minutes). Subserosal layer dissection of more than 90% of the gall bladder bed was achieved in 27 (79%) dogs. Conversion to open surgery was required in three (8.8%) dogs. There were no cases of intraoperative bleeding, bile duct injury, or reoperation. CLINICAL SIGNIFICANCE This study showed that laparoscopic cholecystectomy using the standardised subserosal layer dissection technique could be performed successfully in dogs. Future prospective clinical studies are needed to determine safety and effectiveness of this technique compared to standard techniques.

Abstract
The development of a full-thickness macular hole (FTMH) is a rare complication of intravitreal injections, and only a small subset of eyes with an FTMH has a spontaneous closure. We report a case of repeated FTMH formations and a spontaneous closure following an intravitreal injection of bevacizumab (IVB) for a central retinal vein occlusion (CRVO). A 39-year-old male patient presented with reduced vision in his right eye and was diagnosed with a CRVO. Two months later, neovascular glaucoma and macular edema (ME) developed and IVB was performed. After 2 weeks, optical coherence tomography revealed an improvement of the ME and the formation of an FTMH with a hyperreflective material in the FTMH. Two months later, there was a recurrence of the ME and a closure of the FTMH, but the hyperreflective material was still present in the retina. Then, another IVB and panretinal photocoagulation were performed. One month later, the ME had improved and the FTMH was closed, but the hyperreflective material was still present in the retina. After another 2 months, the ME recurred and a third IVB was performed. The ME improved without a recurrence of an FTMH. After that, there were no recurrences of the ME, but the FTMH recurred with the progression of a posterior vitreous detachment and development of an epiretinal membrane 1 year after the third IVB. We suggest that an FTMH be included as a complication of intravitreal injections, and it may close spontaneously during the course of the primary disease.

Transient Increase of Flicker Electroretinography Amplitudes after Cataract Surgery: Association with Postoperative Inflammation. OPHTHALMOLOGY SCIENCE 2022; 3:100243. [PMID: 36545261 PMCID: PMC9762194 DOI: 10.1016/j.xops.2022.100243] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 10/27/2022] [Accepted: 10/28/2022] [Indexed: 11/06/2022]
Abstract
Purpose To determine the characteristics and cause of the increase in the amplitude of flicker electroretinography (ERG) after cataract surgery. Design Prospective, observational clinical study. Participants Thirty patients who underwent cataract surgery. Methods Flicker ERGs were recorded with the RETeval system without mydriasis. The central macular thickness (CMT) was measured by OCT and the aqueous flare value (AFV) by laser flare-cell photometry. These examinations were performed before surgery and 1 day, 1 week, 1 month, 2 months, and 3 months after surgery. Linear regression analysis through the origin was used to compare the correlations between the relative changes in flicker ERG amplitudes and the changes in the CMT and AFV at different times after the surgery. Main Outcome Measures The amplitude of flicker ERGs, CMT, and AFV. Results The mean amplitude of flicker ERGs increased significantly by 31% at 1 week after surgery (P < 0.001); a significant increase in the amplitudes was not present at 3 months after the surgery. The mean AFV was significantly increased at 1 day after surgery (P < 0.001), and the CMT was significantly increased at 1 to 3 months after surgery (P < 0.001). The changes in flicker ERG amplitudes at 1 week after surgery were significantly associated with the changes in the CMT at 1 to 3 months after surgery (P < 0.05), and they were weakly associated with the changes in AFV at 1 day after surgery (P = 0.05). Conclusions These results suggest that the increase in the amplitude of flicker ERGs after cataract surgery is a transient phenomenon that has a peak at 1 week after surgery. The increase of flicker ERG amplitude was associated with measures that are frequently used to evaluate postoperative inflammation.

Abstract
Abstract
Background
Fibrates activate peroxisome proliferator-activated receptor (PPAR)-α which is associated with lipid metabolism. Bezafibrate is a non-selective PPAR-α agonist, whereas pemafibrate has been developed as a higher selective PPAR-α agonist.
Objective
The efficacy and safety of pemafibrate for 24-week in patients with dyslipidemia was examined in comparison with bezafibrate.
Methods
Sixty patients with hypertriglyceridemia (fasting triglyceride (TG) level of ≥150 mg/dL) were treated with pemafibrate of 0.2 mg/day or bezafibrate of 400 mg/day for 24-week in a randomized cross-over study. Percent change from baseline in TG levels was the primary endpoint, and that in HDL-C and apolipoprotein A-I (Apo A-I) levels was the secondary endpoints.
Results
A significantly greater reduction in TG percent change was observed in pemafibrate than in bezafibrate (−46.1% vs. −34.7%, p<0.001). There was no significant difference in HDL-C percent change between pemafibrate and bezafibrate (18.4% vs. 14.0%, p=0.067), whereas Apo A-I percent change was significantly greater in pemafibrate than in bezafibrate (9.2% vs. 5.7%, p=0.018). Pemafibrate and bezafibrate significantly decreased alanine aminotransferase (ALT) and gamma-glutamyltransferase (γ-GT) levels, and pemafibrate showed a greater reduction than bezafibrate (ALT: −21.9% vs. −10.6%, p=0.048; γ-GT: −43.5% vs. −33.1%, p=0.025). Creatinine levels significantly increased in both treatments (both p<0.001), however, creatinine percent change was significantly smaller in pemafibrate than in bezafibrate (5.72% vs. 15.5%, p<0.001). There was no difference in frequency of adverse event (AE) or serious AE between two treatments, but frequency of creatinine elevation (≥0.5 mg/d and/or 25%) was significantly higher in bezafibrate than in pemafibrate (16/60 vs. 3/60, p=0.004).
Conclusion
As compared with bezafibrate, pemafibrate is more effective to reduce TG levels and to elevate Apo A-I levels, and it is safer in terms of liver and renal function.

Abstract
Background and Objectives: To evaluate the recurrence of diabetic macular edema (DME) after loading an injection of anti-VEGF agents by a pro re nata (PRN) protocol using central retinal thickness (CRT) as a re-injection criterion. Materials and Methods: This is a retrospective, observational single-center study. DME patients with a central retinal thickness (CRT) over 350 μm received a PRN injection of anti-VEGF agents following one to three consecutive monthly loading injections (bevacizumab, ranibizumab, and aflibercept) for 6 months from January 2012 to June 2019. Results: We enrolled a total of 72 eyes for loading injections and the mean CRT improved from 434.04 ± 139.4 μm (before treatment) to 362.9 ± 125.0 μm after the loading injection. One week after injection, 36 eyes (50%) obtained a CRT of ≤350 μm. Fourteen eyes (19.4%) remained with a CRT of ≤350 μm for 6 months without additional injections. A total of 22 eyes (30.6%) had a CRT of >350 μm at 6 months. Fifteen eyes did not receive additional injections because of visual improvement. Conclusions: About 20% of DME patients can be maintained at a CRT of ≤350 μm for 6 months with only a loading injection. However, there is a tendency to delay additional injections for patients with recurrences using PRN protocol.

Abstract
BACKGROUND IgG4-related diseases (IgG4-RDs) are known to disrupt the functioning of multiple organs and are usually associated with mass lesions. Periaortitis, an inflammation of the adventitia and tissues surrounding the aorta, is an example of an IgG4-RD. In ophthalmology, an enlargement of the lacrimal gland is a well-known IgG4-RD, and scleritis has also been reported to be an IgG4-RD although it is rare. We report our findings in a case with periaortitis and posterior scleritis that were present at the same time, and they responded well to systemic steroid therapy. PATIENTS CONCERNS A 79-year-old man with dementia and Lewy bodies was referred to our hospital because of uveitis in both eyes that did not respond to topical steroid therapy. DIAGNOSIS We found anterior scleritis in the right eye and uveitis with shallow anterior chambers in both eyes. B-mode echography showed choroidal detachments (CDs) and a T sign in the right eye. The CDs were assumed to have progressed to the posterior scleritis which then caused the severe vision reduction. The patient was referred to the Internal Medicine Department because the systemic inflammatory disease was suspected due to the high levels of C-reactive protein (CRP) and the fast erythrocyte sedimentation rate. Systemic CT scans showed periaortitis only at the lumbar region. Because of the high levels of IgG4, the patient was diagnosed with IgG4-RD. INTERVENTIONS The patient received intravenous and oral steroid therapy. The first 125 mg of methylprednisolone (mPSL) for 3 days was intravenous, after which it was switched to oral prednisolone (PSL) therapy and the dosage was gradually reduced. OUTCOMES The posterior scleritis and periaortitis responded well to the systemic steroid therapy. One year and a half after the onset of the disease, the patient is still taking 5 mg of PSL. CONCLUSIONS Scleritis with multiple CDs and periaortitis were strongly suspected to be due to IgG4-RD although no definitive diagnosis was made by biopsy of the lesions. Clinicians should be aware that IgG4-RD should be considered as one of the causes of posterior scleritis.

Abstract
Purpose To compare the therapeutic effects of anti-vascular endothelial growth factor (anti-VEGF) agents in eyes with macular edema associated with branch retinal vein occlusion (BRVO-ME) with glaucoma to those without glaucoma. Patients and Methods This retrospective study was conducted using the medical records of Mie University Hospital from 2013 to 2017. Patients were recruited if they had received anti-VEGF agents for BRVO-ME treatment and included 30 patients (30 eyes) without glaucoma (G[-] group) and 27 patients (27 eyes) with glaucoma (G[+] group). The central retinal thickness (CRT) and best-corrected visual acuity (BCVA) at 3 months after a single injection of anti-VEGF agents were compared between the two groups. Results Before treatment, the mean±standard deviation of the CRT was 514.2±117.3 μm for the G[-] group, which was not significantly different from that for the G[+] group (533.4±171.4 μm). The CRT in the G[-] and G[+] groups significantly reduced to 321.1±114.6 μm and 347.8±134.7 μm, respectively, at 1 month after the injection and to 360.4±159.5 μm and 352.4±151.9 μm, respectively, at 3 months after the injection (P<0.01 for each group). The difference in the degree of CRT reduction between the two groups was not significant. Before treatment, the BCVA was 0.42±0.32 logMAR units in the G[-] group and 0.57±0.33 logMAR units in the G[+] group, showing no significant difference. The BCVA in the G[-] and G[+] groups improved significantly to 0.27±0.26 logMAR units and 0.34±0.42 logMAR units, respectively, at 1 month, and to 0.18±0.20 logMAR units and 0.39±0.34 logMAR units, respectively, at 3 months (P<0.01). The BCVA in the G[-] group was significantly better than that in the G[+] group at 3 months (P=0.02). Conclusion The therapeutic response of anti-VEGF agents for BRVO-ME is affected by the presence of glaucoma.

Abstract
Purpose To report the safety and effectiveness of intravitreal aflibercept (IVT-AFL) for diabetic macular edema (DME) in the real-world clinical practice setting in Japan. Methods In this prospective, multicenter, observational, post-marketing surveillance, patients with DME newly receiving IVT-AFL were enrolled. During a 24-month follow-up, the primary outcome was the occurrence of safety events. Other pre-specified endpoints were effectiveness indicators, such as best-corrected visual acuity (BCVA), central retinal thickness, and injection frequency. Results In total, 646 patients administered at least one IVT-AFL injection were included in the safety analysis. During the follow-up period, adverse events occurred in 42 patients (6.50%), whereas adverse drug reactions occurred in 12 (1.86%). In the 12 patients who had adverse drug reactions, seven events occurred in seven patients within the first month of the most recent injection. In addition, 622 patients were included in the effectiveness analysis set. The number of injections over 24 months was 3.6 ± 3.0 (mean ± standard deviation [SD]). BCVA (logarithm of the minimum angle of resolution) was 0.437 ± 0.362 (mean ± SD) (n = 622) at baseline and 0.321 ± 0.348 (n = 177) after 24 months of treatment with IVT-AFL. Central retinal thickness was 440.8 ± 134.2 μm (mean ± SD) (n = 444) at baseline and 355.5 ± 126.4 μm (n = 140) at 24 months. Conclusion Routine administration of IVT-AFL for DME was not associated with new safety concerns, and BCVA outcomes were maintained over 24 months in the real-world setting. Nonetheless, patients in this real-world setting received fewer injections than those in clinical trials, suggesting that a margin for improvement exists in clinical practice.

Abstract
BackgroundActivation of melanocortin 1 receptor (MC1R) is known to have broad anti-inflammatory and anti-fibrotic effects. The bleomycin (BLM)-induced skin fibrosis murine model is well-established for systemic sclerosis (SSc). α-melanocyte-stimulating hormone, an endogenous ligand of MC1R, inhibits skin fibrosis and MC1R knock-out enhances skin fibrosis in this model. These pieces of evidence suggest that MC1R agonism has potential in the treatment of SSc.ObjectivesDersimelagon phosphate (MT-7117) is an investigational small molecule that is an orally administered, selective agonist for MC1R. The purpose of this study is to investigate the potential of MT-7117 as a therapeutic agent for SSc by evaluating its efficacy and mechanism of action in complementary preclinical models. The expression and distribution of MC1R in the skin of SSc patients was investigated.MethodsThe effects of MT-7117 on skin fibrosis and lung inflammation were evaluated in BLM-induced SSc murine models that were optimized for prophylactic and therapeutic evaluation. Microarray-based gene expression analysis and serum protein profiling were performed to investigate the mechanism of action of MT-7117 in the BLM-induced SSc models. The effect of MT-7117 on TGF-β-induced activation of human dermal fibroblasts was evaluated in vitro. Immunohistochemical analyses of MC1R expression in skin samples from SSc patients were performed.ResultsProphylactic treatment with MT-7117 (≥0.3 mg/kg/day p.o.) significantly inhibited the increase in collagen content of the skin, the serum level of surfactant protein D, and the weight of the lungs from BLM-induced skin fibrosis and lung inflammation model. Therapeutic treatment with MT-7117 (≥3 mg/kg/day p.o.) significantly suppressed skin thickening and the numbers of myofibroblasts in pre-established BLM-induced skin fibrosis model. Gene array analysis using the BLM-induced SSc model demonstrated changes in numerous categories related to macrophages, monocytes, and neutrophils, followed by endothelial cell-related categories after treatment with MT-7117. In the analysis that focused on biological functions, categories of inflammatory response, activation of antigen-presenting cells, angiogenesis, atherosclerosis, vasculogenesis, and vaso-occlusion were suppressed by MT-7117. In the analysis that focused on molecular signaling pathways, triggering receptor expressed on myeloid cells-1, IL-6, and oncostatin M involved in inflammation, and peroxisome proliferator-activated receptor that is related to fibrosis were all affected by MT-7117. Serum protein profiling using BLM-induced SSc model revealed that multiple SSc-related biomarkers including P-selectin, osteoprotegerin, cystatin C, growth and differentiation factor-15 and S100A9 were suppressed by MT-7117. MT-7117 inhibited the activation of human dermal fibroblasts by suppressing TGF-β-induced ACTA2 (encoding α-smooth muscle actin) mRNA elevation in vitro. Immunohistochemical analyses showed that MC1R positivity was observed in 40 of 50 diffuse cutaneous SSc patients. MC1R was expressed by monocytes/macrophages, neutrophils, blood vessels (endothelial cells), fibroblasts, and epidermis (keratinocytes) in the skin of SSc patients.ConclusionMT-7117 demonstrates disease-modifying effects in preclinical models of SSc. Investigations of its mechanism of action and target expression analyses indicate that MT-7117 exerts its positive effects by affecting the pathologies of inflammation, vascular dysfunction, and fibrosis through inflammatory cells, endothelial cells, and fibroblasts. In view of its potent beneficial impact on all these three main pathologies of SSc, MT-7117 is a potential therapeutic agent for the treatment of clinically challenging SSc, which has diverse and difficult to treat symptoms. A phase 2 clinical trial investigating the efficacy and tolerability of MT-7117 in patients with early, progressive diffuse cutaneous SSc is currently in progress.Disclosure of InterestsMasahiro Kondo Employee of: Mitsubishi Tanabe Pharma Corporation, Tsuyoshi Suzuki Employee of: Mitsubishi Tanabe Pharma Corporation, Yuko Kawano Employee of: Mitsubishi Tanabe Pharma Corporation, Shinji Kojima Employee of: Mitsubishi Tanabe Pharma Corporation, Masahiko Miyashiro Employee of: Mitsubishi Tanabe Pharma Corporation, Atsuhiro Matsumoto Employee of: Mitsubishi Tanabe Pharma Corporation, Gabriela Kania: None declared, Przemyslaw Blyszczuk: None declared, rebecca ross: None declared, Panji Mulipa: None declared, Francesco Del Galdo Grant/research support from: Prof. F.

Photopic negative response recorded with RETeval system in eyes with optic nerve disorders. Sci Rep 2022; 12:9091. [PMID: 35641565 PMCID: PMC9156775 DOI: 10.1038/s41598-022-12971-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Accepted: 05/13/2022] [Indexed: 11/09/2022] Open
Abstract
Electroretinography (ERG) is used to evaluate the physiological status of the retina and optic nerve. The purpose of this study was to determine the usefulness of ERGs recorded with the RETeval system in diagnosing optic nerve diseases. Forty-eight patients with optic nerve disorders, including optic neuritis, ischemic optic neuropathy, traumatic optic neuropathy, and dominant optic atrophy, and 36 normal control subjects were studied. The amplitudes of the photopic negative response (PhNR) were recorded with the RETeval system without mydriasis. The circumpapillary retinal nerve fiber layer thickness (cpRNFLT) was determined by optical coherence tomography (OCT). The significance of the correlations between the PhNR and cpRNFLT parameters were determined, and the receiver operating curve (ROC) analyses were performed for the PhNR and cpRNFLT. Patients with optic nerve disorders had significantly smaller PhNRs compared to the control subjects (P = 0.001). The ROC analyses indicated that both PhNR and cpRNFLT had comparable diagnostic abilities of detecting optic nerve disorders with PhNR at 0.857 and cpRNFLT at 0.764. The PhNR components recorded with the RETeval system have comparable diagnostic abilities as the cpRNFLT in diagnosing optic nerve disorders.

Background
Orthostatic hypotension (OH) is sometimes observed during cardiac rehabilitation in patients with surgery for aortic dissection. However, little is known about the primary determinant of OH and influence of surgical range on incidence of OH.
Purpose
The aim of this study was to elucidate the incidence of OH in patients with surgery for aortic dissection, and compare it between the patients with ascending aortic replacement surgery (ascending group) and those with ascending aorta and hemiarch or total arch replacement surgery (arch group).
Methods
We analyzed 59 patients who underwent emergent surgery due to Stanford type A aortic dissection from January 2014 to March 2018, and compared the incidence of OH between ascending group (n = 28, age 69.8 ± 11.3 years) and arch group (n = 31, age 64.1 ± 13.0 years).
Results
The incidence of OH in total patients was 30.5%. There were no significant differences in patient characteristics including body tall, body weight, antihypertensive use and progress of rehabilitation between 2 groups. The arch group showed a significant higher incidence of OH as compared with ascending group (arch group: 46.4% vs. ascending group: 16.1%, p = 0.03). Moreover, the patients who occurred OH were significantly taller than those who did not occur OH.
Conclusions
OH was observed in about one third of patients with surgery for aortic dissection and it showed a close relationship with patient’s height and the range repaired by surgical operation. More careful cardiac rehabilitation is needed for tall patients with large area replacement of aorta.

Abstract
The full-field electroretinogram (ERG) is a mass electrophysiological response to diffuse flashes of light and is used widely to assess generalized retinal function. This document, from the International Society for Clinical Electrophysiology of Vision (ISCEV), presents an updated and revised ISCEV Standard for clinical ERG testing. Minimum protocols for basic ERG stimuli, recording methods and reporting are specified, to promote consistency of methods for diagnosis, monitoring and inter-laboratory comparisons, while also responding to evolving clinical practices and technology. The main changes in this updated ISCEV Standard for clinical ERGs include specifying that ERGs may meet the Standard without mydriasis, providing stimuli adequately compensate for non-dilated pupils. There is more detail about analysis of dark-adapted oscillatory potentials (OPs) and the document format has been updated and supplementary content reduced. There is a more detailed review of the origins of the major ERG components. Several tests previously tabulated as additional ERG protocols are now cited as published ISCEV extended protocols. A non-standard abbreviated ERG protocol is described, for use when patient age, compliance or other circumstances preclude ISCEV Standard ERG testing.

Abstract
Aims/Introduction In older patients, the management of diabetic macular edema (DME) can be complicated by comorbidities, geriatric syndrome, and socioeconomic status. This study aims to evaluate the effects of aging on the management of DME. Materials and Methods This is a real‐world clinical study including 1,552 patients with treatment‐naïve center‐involved DME. The patients were categorized into 4 categories by age at baseline (C1, <55; C2, 55–64; C3, 65–74; and C4, ≥75 years). The outcomes were the change in logarithm of the minimum angle of resolution best‐corrected visual acuity (logMAR BCVA) and central retinal thickness (CRT), and the number of treatments from baseline to 2 years. Results From baseline to 2 years, the mean changes in logMAR BCVA from baseline to 2 years were −0.01 in C1, −0.06 in C2, −0.07 in C3, and 0.01 in C4 (P = 0.016), and the mean changes in CRT were −136.2 μm in C1, −108.8 μm in C2, −100.6 μm in C3, and −89.5 μm in C4 (P = 0.008). Treatments applied in the 2 year period exhibited decreasing trends with increasing age category on the number of intravitreal injections of anti‐VEGF agents (P = 0.06), selecting local corticosteroid injection (P = 0.031), vitrectomy (P < 0.001), and laser photocoagulation outside the great vascular arcade (P < 0.001). Conclusions Compared with younger patients with DME, patients with DME aged ≥75 years showed less frequent treatment, a lower BCVA gain, and a smaller CRT decrease. The management and visual outcome in older patients with DME would be unsatisfactory in real‐world clinical practice.

Melanogenic effect of dersimelagon (MT-7117), a novel oral melanocortin 1 receptor agonist. SKIN HEALTH AND DISEASE 2022; 2:e78. [PMID: 35665216 PMCID: PMC9060023 DOI: 10.1002/ski2.78] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 11/05/2021] [Accepted: 11/06/2021] [Indexed: 12/12/2022]
Abstract
Background The activation of melanocortin 1 receptor (MC1R) on melanocytes stimulates the production of eumelanin. A tridecapeptide α melanocyte‐stimulating hormone (αMSH) is known to induce skin pigmentation. Objectives We characterised the properties of a novel oral MC1R agonist dersimelagon (MT‐7117) with respect to its specific binding to MC1R, downstream signalling and eumelanin production in experimental models. Methods The competitive binding and production of intracellular cyclic adenosine 3′, 5′‐monophosphate in cells expressing recombinant melanocortin receptors were examined. A mouse melanoma cell line B16F1 was used for the evaluation of in vitro melanin production. The in vitro activity of MT‐7117 was determined with αMSH and [Nle4, D‐Phe7]‐αMSH (NDP‐αMSH) as reference comparators. The change of coat colour and skin pigmentation were evaluated after repeat administration of MT‐7117 by oral gavage to C57BL/6J‐Ay/+ mice and cynomolgus monkeys, respectively. Results MT‐7117 showed the highest affinity for human MC1R compared to the other melanocortin receptors evaluated and agonistic activity for human, cynomolgus monkey and mouse MC1R, with EC50 values in the nanomolar range. In B16F1 cells, MT‐7117 increased melanin production in a concentration‐dependent manner. In vivo, MT‐7117 (≥0.3 mg/kg/day p.o.) significantly induced coat colour darkening in mice. MT‐7117 (≥1 mg/kg/day p.o.) induced significant skin pigmentation in monkeys and complete reversibility was observed after cessation of its administration. Conclusions MT‐7117 is a novel oral MC1R agonist that induces melanogenesis in vitro and in vivo, suggesting its potential application for the prevention of phototoxic reactions in patients with photodermatoses, such as erythropoietic protoporphyria and X‐linked protoporphyria.
