Oral fluorescein angiography in the diagnosis of paediatric optic nerve abnormalities. Eye (Lond) 2024; 38:1581-1585. [PMID: 38341494 PMCID: PMC11126605 DOI: 10.1038/s41433-024-02956-y] [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: 10/06/2023] [Revised: 01/05/2024] [Accepted: 01/23/2024] [Indexed: 02/12/2024] Open
Abstract
OBJECTIVE FFA is a well-established investigation for the diagnosis of optic nerve abnormalities, requiring an intravenous cannula and extended imaging acquisition time. Cannulation can present a challenge in paediatric patients and whilst oral FFA has been used for decades, it has been limited by imaging technology and unconfirmed image acquisition timings. For years, we have used a modern ultra-widefield retinal camera, and established imaging time-points to demonstrate dynamic optic nerve head changes upon ingestion of fluorescein and collected a database of oFFA images for various presentations. METHODS Using an established protocol, optic nerve colour images were obtained, followed by oral administration of fluorescein dye. The optic nerves are then imaged at established intervals. An interpretation of oFFA tutorial was delivered to consultant ophthalmologists and trainees. Subsequently, these groups were assessed using a series of fifteen cases with the sensitivity and specificity of the test determined. RESULTS Our study presents a series of images and descriptions for common optic nerve abnormalities in paediatric populations. In the interpretation part of the study, overall sensitivity of 76.8% in the consultant group vs 63.3% in the combined consultant + trainees and specificity of 87.5% vs 68.4% in the combined group. CONCLUSIONS This is the first study that describes characteristic features of several common, and serious, optic nerve abnormalities specifically for oFFA interpretation in a paediatric population. It also highlights the rapid accumulation of oFFA interpretation skills in non-specialist consultant and trainee ophthalmologists such as to obtain a high diagnostic accuracy with high sensitivity and specificity.

Considerations in the management of ocular toxoplasmosis in pregnancy: a review of literature. Eye (Lond) 2024; 38:1262-1268. [PMID: 38191658 PMCID: PMC11076467 DOI: 10.1038/s41433-023-02916-y] [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: 06/07/2023] [Revised: 11/27/2023] [Accepted: 12/20/2023] [Indexed: 01/10/2024] Open
Abstract
Ocular toxoplasmosis is the most common cause of infectious posterior uveitis. Available literature is still conflicting regarding the incidence of recurrence during pregnancy as various calculations were employed in the different published studies. Although earlier reports have suggested a difference in presentation and an increase in severity during pregnancy, newer studies appear to show otherwise. Further diagnostic testing, including serologic and intraocular fluid sampling, may be indicated to increase the diagnostic accuracy in this special population of patients. The management of ocular toxoplasmosis during pregnancy is challenging as the foetus is additionally considered in the choice of treatment. Traditionally preferred anti-toxoplasmosis regimens containing antifolate drugs, such as pyrimethamine and trimethoprim-sulfamethoxazole, cannot be used routinely in pregnant patients, especially during the first trimester. This review includes literature on alternative treatments for ocular toxoplasmosis during pregnancy, including spiramycin and intravitreal treatment options.

Real-world experience of implementing the MOLES score in a virtual choroidal naevi clinic at a tertiary referral centre. Eye (Lond) 2024; 38:1183-1188. [PMID: 38057559 PMCID: PMC11009328 DOI: 10.1038/s41433-023-02864-7] [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: 04/12/2023] [Revised: 11/20/2023] [Accepted: 11/21/2023] [Indexed: 12/08/2023] Open
Abstract
INTRODUCTION The MOLES score has been validated to clinically differentiate choroidal naevi from melanomas by ocular oncologists and community optometrists. However, its utility in a virtual choroidal naevi clinic at a tertiary eye hospital without specialist ocular oncology services has not yet been evaluated. METHODS A retrospective case review of 385 choroidal lesions in the virtual choroidal naevus clinic at Bristol Eye Hospital during January-March 2020 and April-August 2021 was performed. Choroidal lesions were assessed using the TFSOM-UHHD risk factor index and MOLES score, respectively. For both study periods, clinical outcome and adherence data were analysed. RESULTS Choroidal lesions scored higher with the TFSOM-UHHD index (median 2) compared to the MOLES score (median 0; p < 0.001). Median required follow-up duration was 2 years for lesions assessed with the TFSOM-UHHD index, and 0 years for those graded with the MOLES score. Overall, 215 patients were appropriately discharged to community optometrists based on their MOLES score. Imaging requirements for the TFSOM-UHHD index and MOLES score protocols were met in 69.1% and 94.8% of cases, respectively. CONCLUSION The MOLES score was easily implemented in a virtual choroidal naevus clinic, with good adherence. It increased clinic capacity by facilitating appropriate discharges of low-risk naevi to community monitoring, allowing finite and specialist hospital-based services to monitor higher-risk naevi more closely.

Prevalence and clinical characteristics of uveitic glaucoma: multicentric study in Bogotá, Colombia. Eye (Lond) 2024; 38:714-722. [PMID: 37789110 PMCID: PMC10920824 DOI: 10.1038/s41433-023-02757-9] [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: 10/18/2022] [Revised: 08/23/2023] [Accepted: 09/15/2023] [Indexed: 10/05/2023] Open
Abstract
OBJECTIVES To describe the clinical features of patients diagnosed with uveitic glaucoma (UG) and ocular hypertension secondary to uveitis (OHT-SU). METHODS A multicentric cross-sectional study using medical records of patients with uveitis between 2013 and 2021. Uveitis and glaucoma specialists examined all patients. Variables were analyzed using the chi-square or Fisher's exact test for categorical variables. Additionally, t test, Mann-Whitney, and Kruskal-Wallis variance analysis were used for continuous variables. Finally, a Kaplan-Meier survival analysis for UG and OHT-SU development over time was done. RESULTS Of the 660 clinical records reviewed of patients with uveitis, 191 (28.9%) had OHT-SU in at least one visit, and 108 (16.4%) of them developed UG. In all ages, females were more affected than males. Anterior uveitis was the main anatomic localisation, and non-granulomatous, recurrent, and inactive uveitis were the most frequent clinical features. The mean final visual acuity was 0.3 (0.0-1.0) LogMAR. Also, 95.8% of the patients had additional sequelae related to uveitis regardless of UG and OHT-SU. Interestingly, males had earlier affection, with statistical significance in OHT for adults (P = 0.036) and UG for children (P = 0.04). Of all patients, 81.1% received topical hypotensive treatment and 29.8% required a surgical procedure. CONCLUSIONS UG and OHT-SU are common complications of uveitis in the Colombian population. These sight-threatening conditions were more common and appeared sooner in men at any age. Our results suggest that earlier and more aggressive treatment with topical hypotensive agents could positively influence the visual outcomes and the requirement of surgical procedures.

Vessel density on optical coherence tomography angiography is prognostic for future disease course in intermediate uveitis. Sci Rep 2024; 14:2933. [PMID: 38317017 PMCID: PMC10844199 DOI: 10.1038/s41598-023-49926-0] [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: 05/19/2023] [Accepted: 12/13/2023] [Indexed: 02/07/2024] Open
Abstract
As most rare diseases, intermediate uveitis lacks reliable endpoints necessary for randomized clinical trials. Therefore, we investigated longitudinal changes of retinal and choriocapillaris perfusion on optical coherence tomography angiography (OCT-A) in intermediate uveitis and their prognostic value for future best corrected visual acuity (BCVA) and central retinal thickness (CRT). In this retrospective, longitudinal cohort study eyes of patients with intermediate uveitis were imaged by swept-source OCT-A (macula-centered 3 × 3 mm; PLEX Elite 9000, Zeiss) and stratified into clinically stable, worsened and improved based on changes in clinical parameters. Superficial (SRL) and deep retinal layers (DRL) were automatically analyzed for vessel density (VD) and choriocapillaris layer for non-perfused area (CCNPA) using ImageJ. Mixed-effects regression analysis controlling for age, sex, and OCT-A signal strength index (SSI) was used to evaluate the prognostic value of OCT-A parameters. 91 eyes (62 stable, 12 worsened, and 17 improved) were included in the analysis and mean follow-up time was 296 days. Longitudinal changes of VD were different between all three groups (p = 0.002 for SRL and p = 0.017 for DRL). Clinically worsened eyes showed a decrease in VD (- 0.032 ± 0.055 for SRL and - 0.027 ± 0.025 for DRL), whereas clinically improved eyes showed an increase in VD (0.037 ± 0.039 for SRL and 0.001 ± 0.023 for DRL). No difference was found for CCNPA. When controlling for age, sex, and SSI, observed differences held true in clinically worsened eyes for DRL (p = 0.011) and in clinically improved eyes for SRL (p = 0.002). An increase of CCNPA in clinically worsened eyes (p = 0.03) compared to clinically stable and improved eyes was evident. Predictive analysis revealed an association of VD in SRL and DRL at baseline with BCVA at follow-up (p = 0.039 and p = 0.047, respectively) and of VD in SRL at baseline with CRT at follow-up (p = 0.046). Alterations in retinal perfusion on OCT-A in intermediate uveitis are partly reversible and OCT-A VD may serve to predict future BCVA and CRT. Thus, perfusion parameters on OCT-A might aid monitoring and serve as prognostic imaging-biomarker.

Show don't tell: assessing the impact of co-developed patient information videos in paediatric uveitis. Eye (Lond) 2024; 38:246-252. [PMID: 37460691 PMCID: PMC10810776 DOI: 10.1038/s41433-023-02659-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Accepted: 06/26/2023] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND/OBJECTIVES There is a paucity of online educational content targeting children and young people with uveitis. We evaluated the impact of a co-designed patient education video on subjective and objective understanding of childhood uveitis. SUBJECTS/METHODS Co-designed patient education media were produced in collaboration with the Childhood Uveitis Studies steering group and the Great Ormond Street Hospital Generation R Young People's Advisory Group and narrated by children. Patients managed within the Uveitis service at GOSH were invited to take part in a pre-post survey, undertaken immediately prior to and following viewing of a patient education video. RESULTS Forty-three patients participated. These were stratified according to age, duration of disease, and treatment type for analysis. Self-rated knowledge improved across all groups (p = 0.001), particularly in those with a new diagnosis of uveitis (Z = -8.124, p < 0.001). Objective knowledge scores improved across all questions, especially in younger children, those with new disease, and those on steroid only treatment (Z = -3.847, p < 0.001, Z = -3.975, p < 0.001, Z = -3.448, p < 0.001; respectively). Most participants reported the videos to be easy to understand and with the right amount of information. All stated that they learned something new. CONCLUSIONS Patient understanding of disease and treatment is crucial to achieving the best possible outcomes for this chronic, relapsing remitting and potentially blinding disorder. Our findings data shows the potential value of co-designed patient information videos, specifically in our study benefitting younger patients and those recently diagnosed. We suggest that other clinical teams could collaborate fruitfully with patient groups to develop similar videos to target possible misinformation and potentially improve patient outcomes.

Abstract
BACKGROUND Autoimmunity and deficiency of the transcription factor autoimmune regulator protein (AIRE) are known associations with Down syndrome (DS). Lack of AIRE abrogates thymic tolerance. The autoimmune eye disease associated with DS has not been characterized. We identified a series of subjects with DS (n = 8) and uveitis. In three consecutive subjects, we tested the hypothesis that autoimmunity to retinal antigens might be a contributing factor. SUBJECTS/METHODS This was a multicentred, retrospective case series. Deidentified clinical data of subjects with both DS and uveitis were collected via questionnaire by uveitis-trained ophthalmologists. Anti-retinal autoantibodies (AAbs) were detected using an Autoimmune Retinopathy Panel tested in the OHSU Ocular Immunology Laboratory. RESULTS We characterized eight subjects (mean age 29 [range, 19-37] years). The mean age of detected uveitis onset was 23.5 [range, 11-33] years. All eight subjects had bilateral uveitis (p < 0.001 based on comparison to published university referral patterns), with anterior and intermediate uveitis found in six and five subjects respectively. Each of three subjects tested for anti-retinal AAbs was positive. Detected AAbs included anti-carbonic anhydrase II, anti-enolase, anti-arrestin, and anti-aldolase. DISCUSSION A partial deficiency in the AIRE on chromosome 21 has been described in DS. The similarities in the uveitis presentations within this patient group, the known autoimmune disease predisposition in DS, the recognized association of DS and AIRE deficiency, the reported detection of anti-retinal antibodies in patients with DS in general, and the presence of anti-retinal AAbs in three subjects in our series supports a causal association between DS and autoimmune eye disease.

Abstract
OBJECTIVE To assess the association of skin color using Fitzpatrick Skin Type (FST) with metastatic risk of uveal melanoma. SUBJECTS 854 consecutive patients with uveal melanoma and documented FST. METHODS Retrospective detailed review of patient charts was performed for FST (type I- white, II-fair, III-average, IV-light brown, V-brown, VI-black), clinical details of the patient and the uveal melanoma, tumor cytogenetic classification according to The Cancer Genome Atlas (TCGA), and outcome of melanoma-related metastasis and death. RESULTS The FST classification was type I (n = 97 patients), type II (n = 665), type III (n = 79), type IV (n = 11), type V (n = 2), type VI (n = 0). A comparison of patient FST (type I vs. II vs. III-V) revealed significant differences in mean age at presentation (64.1 vs. 58.5 vs. 49.8 years, p < 0.001), race white (100% vs. 98% vs. 75%, p < 0.001), presence of ocular melanocytosis (3% vs. 3% vs. 10%, p = 0.01), visual acuity <20/200 at presentation (6% vs. 7% vs. 13%, p = 0.03), genetic results showing TCGA group B tumors (11% vs. 14% vs. 26%, p = 0.01) or TCGA group D tumors (22% vs. 11% vs. 9%, p = 0.01), 10-year incidence of melanoma-related metastasis (25% vs. 15% vs. 14%, p = 0.02) and 10-year incidence of melanoma-related death (9% vs. 3% vs. 4%, p = 0.04). FST was a significant predictor of melanoma-related metastasis (p = 0.02, Hazard ratio 2.3). CONCLUSIONS Fitzpatrick skin type may be a predictor of melanoma-related metastasis, with metastasis and TCGA Group D tumors being more common in patients with FST I.

Abstract
BACKGROUND/OBJECTIVES Uveitis in children and young people (CYP) is a rare but potentially debilitating condition. Steroid eye drops are the first step in treatment and poor compliance may result in vision-threatening complications. This study aims to measure compliance with prescribed eye drops prospectively in a child-specific manner. SUBJECTS/METHODS Patients aged 0-18 years attending a tertiary paediatric uveitis clinic using steroid drops were recruited. Both the CYP, and person with parental responsibility (PPR) completed questionnaires about compliance. A subgroup had bottles of Prednisolone 1% drops dispensed and weighed at the first appointment and reweighed at follow-up. The weight reduction was compared with expected weight change over the interval. RESULTS The study was completed by 42 patients of the 50 patients recruited. Thirty-one CYP and their respective PPR completed both questionnaires, 11 completed only one questionnaire (9 CYP, 2 PPR). Drop errors for all eye drops were reported more than "once a week" by 13/39 CYP (33.3%, 95% CI: 19.1%-50.2% of respondents), and 3/31 PPR (9.7%, CI: 19.1%-50.2% of respondents). Many PPR could not recall prescribed drop frequency (n = 13/31, 40.6%, CI: 23.7%-59.4% of respondents). Twelve patients had bottles weighed and returned. Insufficient weight reduction was found in 9 (75%, CI: 42.8%-94.5%). Within the eye drop weighing subgroup three participants (25%, CI: 5.5%-57.2%) used <50% the expected weight of drops. CONCLUSIONS This study demonstrated poor eye drop compliance in CYP with uveitis. Self-reported compliance was unreliable in this population. Worryingly, some patients miss more than 50% of drops and may suffer sub-optimal disease control.

Abstract
PURPOSE To describe the various ocular clinical features and visual outcomes in Tubulointerstitial Nephritis and Uveitis Syndrome (TINU). METHODS The medical records of 13 patients (26 eyes) diagnosed with TINU were reviewed. RESULTS Twenty-six (26) eyes of 13 patients with TINU were reviewed in this study. The median age at onset of uveitis was 14 (range, 9-45). Eight (61.5%) subjects were female. The median follow-up of patients was 30 months (range, 6-89 months). Posterior segment findings were seen in 18 eyes of 9 patients (69.2%). The most common posterior findings were optic nerve head inflammation (16 eyes, 88.8%) and retinal vasculitis (13 eyes, 72.2%). Other posterior findings included vitritis (8 eyes, 44.4%), macular edema (6 eyes, 33.3%), snowball (4 eyes, 22.2%), and chorioretinal lesions (2 eye, 11.1%). Eight patients had fluorescein angiography (FA) data available and most eyes had retinal capillary leakage (13 eyes, 81.2%) followed by optic disc staining/leakage (12 eyes, 75%). Twelve (12) patients (92.3%) were treated with immunomodulatory treatment (IMT) and/or biologics. Five patients (%38.4) required biologics to control intraocular inflammation. CONCLUSION Posterior segment involvement may be common in patients with TINU syndrome. FA provides significant information for detecting posterior segment involvement and disease activity in TINU. The majority of patients required systemic treatment in order to control intraocular inflammation and prevent relapses.

Material risk: vitreoretinal surgery, evisceration, enucleation and sympathetic ophthalmia-where are we currently? Eye (Lond) 2023; 37:3542-3550. [PMID: 37198435 PMCID: PMC10686393 DOI: 10.1038/s41433-023-02562-4] [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: 05/28/2022] [Revised: 04/04/2023] [Accepted: 04/24/2023] [Indexed: 05/19/2023] Open
Abstract
Sympathetic ophthalmia (SO) is known to occur after severe penetrating eye injury, evisceration and even enucleation surgery. Recent evidence suggests that a greater risk lies after multiple vitreoretinal procedures. The risk of SO following evisceration is only minimally greater than that following enucleation surgery. This review evaluates literature on SO to date and provides figures for the risk of developing SO for the purposes of the consent process. The issue of SO and Material Risk following vitreoretinal surgery is reviewed and figures for the purposes of consent are outlined. This is of particular relevance for patients in whom the contralateral eye is and will likely remain the better seeing eye. Sympathetic ophthalmitis is known to occur after severe penetrating eye injury, after evisceration and enucleation. More recently, sympathetic ophthalmitis has been recognised to occur after vitreoretinal surgery. This article reviews the evidence on material risk when consenting patients for elective and emergency eye procedures after ocular trauma or surgery. When a globe needs to be removed because of irreparable ocular injury, previous publications dictated the procedure to be an enucleation because of the fear of an increased risk of SO after an evisceration. Perhaps the issue of material risk of sympathetic ophthalmia (SO) remains over-emphasised by ophthalmic plastic surgeons and under-recognised by vitreoretinal surgeons during the consent process for evisceration, enucleation and vitreoretinal surgery. Antecedent trauma and number of previous surgeries may actually be a more significant risk factor than the type of eye removal. Recent medicolegal cases also help us understand the importance of the discussion of this risk. We present our current understanding of the risk of SO after different procedures and suggest how this information may be included in a patient consent.

Abstract
Anterior Uveitis (AU) is the inflammation of the anterior part of the eye, the iris and ciliary body and is strongly associated with HLA-B*27. We report AU exome sequencing results from eight independent cohorts consisting of 3,850 cases and 916,549 controls. We identify common genome-wide significant loci in HLA-B (OR = 3.37, p = 1.03e-196) and ERAP1 (OR = 0.86, p = 1.1e-08), and find IPMK (OR = 9.4, p = 4.42e-09) and IDO2 (OR = 3.61, p = 6.16e-08) as genome-wide significant genes based on the burden of rare coding variants. Dividing the cohort into HLA-B*27 positive and negative individuals, we find ERAP1 haplotype is strongly protective only for B*27-positive AU (OR = 0.73, p = 5.2e-10). Investigation of B*27-negative AU identifies a common signal near HLA-DPB1 (rs3117230, OR = 1.26, p = 2.7e-08), risk genes IPMK and IDO2, and several additional candidate risk genes, including ADGFR5, STXBP2, and ACHE. Taken together, we decipher the genetics underlying B*27-positive and -negative AU and identify rare and common genetic signals for both subtypes of disease.

Abstract
BACKGROUND Birdshot Retinochoroiditis (BSRC) is a rare, chronic posterior uveitis that is strongly associated with HLA-A*29.2 positivity. To date, no robust incidence studies of BSRC have been undertaken. We present the first epidemiological study of BSRC in a high-prevalence region. METHODS In collaboration with the British Ophthalmological Surveillance Unit, all new cases of BSRC between May 2017 and June 2019 were prospectively collected. Presenting demographics, symptoms, signs and treatment modalities were collected. A follow-up questionnaire twelve months later was also sent. RESULTS Thirty-seven confirmed cases meeting the reporting criteria were identified. Twenty-three cases had both baseline and follow-up data. The total population incidence of BSRC was 0.035 cases per 100,000 person-years [95% CI 0.025-0.048 cases per 100 000 people]. 97.3% were HLA-A*29 positive. The median age was 46 years, with females making up 78% of patients. There were no significant differences in the latitudinal incidence of BSRC. At presentation, floaters were the most common symptom. Optic disc swelling was the most common sign. Mean presenting visual acuity was independent of symptom duration. Combined systemic corticosteroids and immunomodulatory therapy were the most common treatments at baseline and follow-up. Intravitreal steroids were equally popular at follow-up. CONCLUSIONS This study provides the first nationwide estimate of the incidence of BSRC in a high-prevalence region. Cases were more common in females, with a broad range of presentation ages. No significant latitudinal effect of incidence was identified. Systemic therapy with steroids and IMT remain the most common treatments.

HLA-DRB1*04:05 is involved in the development of Vogt-Koyanagi-Harada disease-like immune-related adverse events in patients receiving immune checkpoint inhibitors. Sci Rep 2023; 13:13580. [PMID: 37604934 PMCID: PMC10442432 DOI: 10.1038/s41598-023-40565-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 08/13/2023] [Indexed: 08/23/2023] Open
Abstract
Immune checkpoint inhibitors (ICIs) activate anti-tumor activity by inhibiting immune checkpoint molecules that suppress inflammatory T-cell activity. However, ICIs can initiate excessive immune responses, thereby causing immune-related adverse events (irAEs). ICI-associated uveitis (ICIU) is an irAE that affects the eyes. Although Vogt-Koyanagi-Harada disease (VKH)-like uveitis is a common form of ICIU, it is unclear which factors determine the ICIU form. We retrospectively reviewed the medical records of nine ICIU cases treated with ICIs for malignancies. We also performed HLA typing in seven cases to investigate the association between HLA and disease type. Fisher's exact test was used for the statistical analysis. Five of the ICIU cases were VKH-like ICIUs, and four were non-VKH-like ICIUs. No association was found between mean age, sex, primary disease, ICI, time to onset, and disease type. Four patients with VKH-like uveitis underwent HLA genotyping and were all positive for HLA-DRB1*04:05. All 3 patients with non-VKH-like uveitis were negative for HLA-DRB1*04:05. Statistical analysis showed that HLA-DRB1*04:05 was significantly associated with developing VKH-like ICIU (P = 0.029). In ICIU, HLA-DRB1*04:05 was associated with the pathogenesis of VKH-like uveitis, suggesting that ICI-associated VKH-like uveitis has a similar pathogenesis to VKH.

Vision-related quality of life in patients treated for ocular syphilis. Sci Rep 2023; 13:13413. [PMID: 37591975 PMCID: PMC10435556 DOI: 10.1038/s41598-023-40289-0] [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: 03/13/2023] [Accepted: 08/08/2023] [Indexed: 08/19/2023] Open
Abstract
Multiple studies have showed negative impact of non-infectious uveitis on quality of life (QoL). Less is understood regarding life experiences in patients with infectious uveitis. We investigated vision-related QoL in individuals who had recovered from ocular syphilis. 32 adults treated for ocular syphilis at a uveitis service in Brazil completed the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25), and a comprehensive ophthalmic examination was performed. Medical records were reviewed to confirm resolution of ocular inflammation for 3 months pre-enrolment, and collect clinical data. The NEI VFQ-25 composite score was low overall (75.5 ± 19.8, mean ± standard deviation), and subscale scores varied from relative lows of 59.1 ± 39.6 (driving) and 60.9 ± 24.5 (mental health), to relative highs of 84.8 ± 21.8 (ocular) and 89.1 ± 21.0 (color vision). Adults aged over 40 years and those with a final visual acuity of 20/50 or worse had significantly lower mean composite and subscale scores. Other clinical characteristics-including gender, HIV co-infection, and type of uveitis-did not significantly influence scores. Our findings, taken in context with previous observations that prompt recognition achieves better vision outcomes, suggest early treatment may improve QoL after recovery from ocular syphilis.

Quantitative analysis of choroidal morphology in preeclampsia during pregnancy according to retinal change. Sci Rep 2023; 13:13171. [PMID: 37580383 PMCID: PMC10425443 DOI: 10.1038/s41598-023-40144-2] [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: 03/19/2023] [Accepted: 08/05/2023] [Indexed: 08/16/2023] Open
Abstract
We sought to investigate changes in choroidal hemodynamics in preeclampsia according to presence of retinal change by quantitatively assessing choroidal vessels using optical coherence tomography (OCT). This retrospective study included 106 eyes (of 53 patients) with preeclampsia, including 70 eyes without retinal change in patients with preeclampsia (Group A), 22 eyes with retinal change in patients with preeclampsia (Group B), and 14 eyes of normal pregnant women (controls). Subfoveal choroidal thickness (SFCT) was measured on OCT B-scan images, and choroidal vessel densities (CVDs) were calculated using binarized OCT B-scan and en face images. Their values were then correlated with clinical parameters associated with preeclampsia. SFCT was greater in Group B compared to Group A or controls (354.32 ± 65.13 vs. 288 ± 55.68 or 277.21 ± 50.08, both P < 0.001). CVD on B-scan images was greater in Group B compared to Group A or controls (76.4 ± 4.9 vs. 73.7 ± 5.3 or 71.5 ± 5.1; both P ≤ 0.046). CVD on en face images was also greater in Group B compared to Group A or controls (64.7 ± 0.8 vs. 63.6 ± 1.5 or 63.3 ± 1.3; both P ≤ 0.001). SFCT and CVD positively correlated with each other (P ≤ 0.009) and were greater in patients with blurred vision and vaginal bleeding (P ≤ 0.020 for blurred vision and P ≤ 0.024 for vaginal bleeding). SFCT and CVDs were higher in preeclampsia patients with retinal change compared to those without retinal change or controls. Both SFCT and CVD showed association with blurred vision and vaginal bleeding.

Six-month outcomes of infliximab and tocilizumab therapy in non-infectious retinal vasculitis. Eye (Lond) 2023; 37:2197-2203. [PMID: 36443499 PMCID: PMC10366079 DOI: 10.1038/s41433-022-02315-9] [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: 03/02/2022] [Revised: 09/03/2022] [Accepted: 11/11/2022] [Indexed: 11/29/2022] Open
Abstract
PURPOSE To evaluate the efficacy of infliximab (IFX, 5-10 mg/kg) (Group 1) and tocilizumab (TCZ, 4-8 mg/kg) (Group 2) infusions in non-infectious retinal vasculitis (RV) using Angiographic Scoring for the Uveitis Working Group fluorescein angiography (FA) scoring system. METHODS Records of 14 patients (24 eyes) in Group 1 and 8 patients (11 eyes) in Group 2 were retrospectively evaluated to assess visual acuity (VA), anterior chamber cell and flare, vitreous haze, central subfield thickness (CST), and FA scoring at baseline and 6 months of follow-up. The measurements were employed to grade in each group. RESULTS In Group 1 and 2, respectively, there was no underlying disease in 9 (60%) and 3 (42.9%) patients. Three (42.9%) patients in Group 2 had juvenile idiopathic arthritis (JIA) as the most common identified cause. Mean improvement in VA (log MAR) and CST were 0.04 ± 0.14 and 40.3 ± 78.5 µm in Group 1; 0.04 ± 0.09 and 47.3 ± 82.3 µm in Group 2, respectively. Mean FA scores were significantly reduced from 12.4 ± 5.2 and 11.6 ± 4.4 at baseline to 6.4 ± 5.0 and 5.8 ± 3.9 at 6-month in Group 1 and 2, respectively. In Group 2, 9 eyes of 6 patients (75%) had the history of IFX use prior to TCZ initiation. There was no significant safety concern requiring treatment discontinuation during the follow-up in either group. CONCLUSION IFX and TCZ infusions showed statistically significant improvement of non-infectious RV as shown by ASUWOG FA Scoring System. TCZ, as well as IFX, appeared to be effective treatment options for non-infectious RV.

Abstract
PURPOSE To describe the surgical management of presumed trematode-induced granulomatous intermediate uveitis (PTIGIU) not responding to medical treatment in controlling the inflammation. METHODS A prospective, interventional, single-center study in which patients with a history of fresh canal water contact and PTIGIU were enrolled. All patients underwent lensectomy-pars plana vitrectomy (PPV) and post-operative control of inflammation, functional and anatomical outcomes were assessed. RESULTS Fifteen eyes of 12 patients were included in the study with median age of 11.6 ± 4 yrs. Six months following lensectomy-PPV, inflammation was well controlled in all patients. The eyes were divided into two groups: Group A: 10 patients with an attached retina while Group B: 5 patients who were in the cicatricial stage with tractional retinal detachment. All patients in group A had CDVA of 20/40 or better, unlike patients in group B who failed to achieve a CDVA better than 20/70 throughout their follow-up. In group B, final anatomical success was achieved in only 40% with hypotony occurring in 20%. CONCLUSION PTIGIU is associated with the presence of ciliary body granuloma which, if left untreated, can lead to drastic outcomes. Early lensectomy-PPV represents a viable management option in cases resistant to medical treatment, with a favorable outcome.

Abstract
BACKGROUND Visual outcomes after primary tumour treatment of uveal melanoma (UM) have been investigated repeatedly. This study evaluates the correlation between best-corrected visual acuity (BCVA) before treatment with clinicopathological factors and patient survival. SUBJECTS/METHODS Pre-treatment BCVA was examined in relation to tumour dimensions and location, and survival in a retrospective cohort of 1809 patients who underwent plaque brachytherapy. BCVA was also correlated to tumour histological factors in a second cohort of 137 enucleated eyes. RESULTS The mean BCVA of the tumour eye prior to plaque brachytherapy was LogMAR 0.42 (SD 0.46). Patients with low BCVA (LogMAR ≥ 1.00) did not differ in age (p = 0.19) and had similar frequency of ciliary body involvement (p = 0.99) but had tumours with greater apical thickness (p < 0.0001), greater diameter (p < 0.0001) and shorter distance to the optic disc and fovea (p < 0.0001). There were no significant relations between low BCVA and any of 13 examined tumour histological factors at a Bonferroni-corrected significance level (p > 0.004). Patients with low BCVA had greater incidence of UM-related mortality in competing risk analysis (p = 0.0019) and shorter overall survival (p < 0.0001). Low BCVA was also associated with increased hazard ratio (HR) for UM-related mortality in univariate analysis (HR 1.5, 95% confidence interval 1.2 to 1.9), but not in multivariate analysis with tumour size and location as covariates. CONCLUSIONS UM patients with low BCVA before primary tumour treatment have a worse prognosis, likely related to increased tumour dimensions. Future studies should examine the prognostic significance of BCVA in relation to macula-involving retinal detachment and genetic factors.

Abstract
Biologics are increasingly used to treat Vogt-Koyanagi-Harada disease, but head-to-head comparisons with conventional immunosuppressants are lacking. Here in this randomized trial (Chinese Clinical Trial Registry, ChiCTR2100043061), we assigned 110 patients (27 early-phase and 83 late-phase) to cyclosporine-based immunosuppressant strategy (N = 56) or adalimumab-based biologic strategy (N = 54), each combined with a modified corticosteroid regimen. The primary outcome is change from baseline in best-corrected visual acuity at week 26. The margin of non-inferiority for cyclosporine is -7 letters. The primary outcome is 11.2 letters (95% CI, 7.5 to 14.9) in the cyclosporine group and 6.3 letters (95% CI, 3.1 to 9.6) in the adalimumab group (difference, 4.9; 95% CI, 0.2 to 9.5; P < 0.001 for non-inferiority). The between-group difference is -0.8 letters (95% CI, -6.1 to 4.5) in early-phase disease and 5.7 letters (95% CI, 0.2 to 11.2) in late-phase. Serious adverse events are reported less frequently in the cyclosporine group than in the adalimumab group (0.70 vs. 1.21 events per patient-year). Here, we report that combined with a non-standard corticosteroid regimen, cyclosporine-based immunosuppressant strategy is non-inferior to adalimumab-based biologic strategy by 26 weeks for visual improvement in a cohort of patients with Vogt-Koyanagi-Harada disease, 75% of whom have a late-phase disease.

Abstract
OBJECTIVES To evaluate the long term complications and vision loss in HLA-B27 uveitis. METHODS Retrospective review of subjects with HLA-B27 uveitis in a public tertiary centre between January 2008 and 2020. RESULTS 562 HLA-B27-positive subjects (834 eyes) had mean follow-up of 9.8 years (8173.2 eye-years). Median visual acuity at ten years was 0.1 logMAR (IQR 0.0-0.1). Complications occurred in 404 eyes (48.4%): posterior synechiae (39.7%), cataract (22.1%), elevated intraocular pressure (15.5%), cystoid macular oedema (6.0%). Permanent moderate vision loss ( ≤ 0.4 logMAR) due to uveitis occurred in 14 eyes (1.7%) and severe vision loss (≤ 1.0 logMAR) in 7 eyes (0.8%). Complications were more common with older age (OR 1.017 p = 0.016), chronic inflammation (OR 5.272 p < 0.001) and intermediate uveitis (OR 5.982 p < 0.001). CONCLUSIONS Complications are frequent in HLA-B27 uveitis, especially in older subjects, chronic inflammation and intermediate uveitis. Despite this, the majority of subjects maintain good visual prognosis.

Paediatric anterior uveitis management in the USA: a single-centre, 10-year retrospective chart review exploring the efficacy and safety of systemic immunomodulatory therapy. Eye (Lond) 2023; 37:1325-1330.

Abstract
OBJECTIVE To evaluate the efficacy of immunomodulatory therapy (IMT) in paediatric anterior uveitis. METHODS Chart review of all patients ≤ 18 years treated for anterior uveitis using a stepladder approach during a 10-year period. The type and duration of IMT were noted. The data were analysed depending on chronicity, aetiology, and type of IMT using appropriate statistical tests. The outcome measures included ocular complications, the need for surgical intervention, and visual outcomes. RESULTS One hundred and thirty-four patients (191 eyes) were analyzed. The median age at diagnosis was 7 years (interquartile range (IQR): 7.5 years). The median follow-up was 4 years (IQR: 6 years). The most common causes of anterior uveitis were Juvenile idiopathic arthritis (64 patients, 47.8%) and undifferentiated (33 patients, 24.6%). All patients were started on topical steroids and cycloplegics. 94 (70%) patients required IMT. 92 (68.6%) were started on Methotrexate as the first agent, of which 21 (22%) were switched to a different agent owing to side effects. Biologic agent was added in 55 (41%) patients. 21 (16%) required switch to a second biologic agent, 5 (3.7%) to third, and 1 (0.8%) to fourth biologic agent. At the last exam, 11 (8%) had persistent inflammation. 55 (41%) had ocular complications, and 113 (84%) had a best corrected visual acuity ≥ 20/40. CONCLUSION Early introduction of IMT and switch to different agents may be required to control anterior uveitis and reduce the complications in children. IMT is safe and effective in treating paediatric anterior uveitis.

Abstract
OBJECTIVES To investigate the association of optic nerve head (ONH) swelling in the acute uveitic phase of Vogt-Koyanagi-Harada (VKH) disease with blood flow velocity in the choroid and ONH and oxygen saturation and diameter of retinal vessels. METHODS In this prospective study, 25 patients (50 eyes) were studied. Thirteen patients (26 eyes) had ONH swelling and 12 patients (24 eyes) had no ONH swelling. Laser speckle flowgraphy (LSFG) and retinal oximetry measurements were performed at presentation. RESULTS In the ONH, mean blur rate (MBR)-vessel, representing blood flow velocity in retinal vessels, was significantly lower in the eyes affected by ONH swelling, while choroidal MBR was not significantly different. Eyes with ONH swelling had a significantly lower oxygen saturation in retinal venules, a significantly higher arteriovenous oxygen saturation difference and a significantly smaller calibre of retinal arterioles compared with eyes without ONH swelling. There were significant positive correlations between the MBR-vessel of the ONH and venular oxygen saturation and calibre of retinal arterioles. In addition, MBR-vessel of the ONH had a significant negative correlation with arteriovenous oxygen saturation difference. CONCLUSIONS The occurrence of ONH swelling in the acute uveitic phase of VKH disease is associated with lower retinal blood flow velocity and smaller calibre of retinal arterioles as well as lower oxygen saturation in retinal venules and higher arteriovenous difference in oxygen saturation.

Abstract
BACKGROUND/OBJECTIVES To investigate post-enucleation outcomes and assess the effect of extrascleral extension (ESE) on these outcomes for patients with uveal melanoma (UM) managed at a tertiary referral centre in Scotland. SUBJECTS/METHODS Retrospective review of all cases of UM managed by the Scottish Ocular Oncology Service for which enucleation was undertaken between 13/03/2008 and 31/12/2020. Primary outcomes were length of survival, time-to-metastasis (TTM) and local recurrence rate. Secondary outcomes were the effects of the presence of ESE, ESE size, and the use of adjuvant external beam radiotherapy (EBRT) on the primary outcomes. RESULTS Of 172 enucleated UMs, 32 (18.6%) had ESE. Over a median follow-up period of 33.7 months (range = 1.1-163.7 months), 91 (52.9%) patients died. The median length of all-cause survival of 54.1 months (range = 1.1-163.7 months). One-year, 5-year, and 10-year survival rates were 84.8%, 49.1%, and 30.9%, respectively. Eighty-four (49.7%) patients had metastatic disease. The median TTM of 42.2 months (range = 0.4-106.8 months). Proportions of patients who developed metastases within 1-year, 5-years and 10-years post-enucleation were 22.7%, 52.8%, and 71.8%, respectively. There was one instance of local orbital recurrence. ESE was associated with a significantly shorter length of survival (p = 0.03). There was a trend towards a shorter length of survival and TTM with ESE > 5 mm and those who received adjuvant EBRT. CONCLUSIONS ESE was present in one-sixth of our cohort and was associated with a significantly shorter length of survival, particularly in the presence of ESE > 5 mm or high-risk characteristics warranting adjuvant EBRT. This data will aid prognostication of the patients in our service.

Abstract
Uveitic glaucoma (UG) is sometimes intractable, including intricate interaction between intraocular pressure (IOP) elevation associated with inflammation and side effects of steroids. Based on the Tube Versus Trabeculectomy study in refractory glaucoma results in 2012, tube shunt surgeries have been performed for UG, but few reports have focused on UG. We retrospectively examined the surgical efficacy, complications, and risk factors in 62 eyes with UG that underwent Baerveldt glaucoma drainage device (BGD) implantation at Kumamoto University. The IOPs significantly dropped, and the mean number of glaucoma medications was reduced by more than two. Kaplan‒Meier survival curves were presented under 2 conditions: an IOP reduction of 20% and 6 ≤ IOP ≤ 18 mmHg (criterion A) or 6 ≤ IOP ≤ 15 mmHg (criterion B). In criterion A, the median survival times (MST) were 124 days (complete) and 997 days (qualified). In criterion B, the MST was 129 days (complete) and 867 days (qualified). The Cox hazard proportional model found that the hazard ratio was 0.170 for a history of cataract surgery (95% CI 0.0303-0.950) and 8.669 for systemic immunosuppressive therapy (95% CI 1.810-41.51). BGD implantation is effective for treating UG, but the presence of systemic treatment and the lens status should be considered.

Abstract
PURPOSE To examine the association of uveitis with hepatitis B (HBV) and hepatitis C (HCV) chronic infections METHOD: This is a population-based cross-sectional study. The study encompassed 13,183 consecutive patients with uveitis and 65,331control subjects. The prevalence of chronic HBV and HCV infections was compared between patients diagnosed with uveitis and age-, sex-, and ethnicity-matched controls. Lifetime prevalence rates of HBV and HCV were calculated for patients with uveitis and control individuals. Odds ratio (OR) for HBV and HCV was evaluated across different strata. RESULTS The lifetime prevalence rate of chronic HBV infection was greater in patients with uveitis than in controls (1.2% vs. 0.8%, respectively; P < 0.001). The association of HBV with uveitis was statistically significant among individuals older than 40 years of age, both sexes, and individuals of Jewish ethnicity. The lifetime prevalence of HCV was comparable between patients with uveitis and controls (0.8% vs. 0.7%, respectively; P = 0.189). Thus, no independently significant association was found between uveitis and HCV (fully-adjusted OR, 1.15; 95% CI, 0.93-1.42; P = 0.211). CONCLUSIONS Uveitis is associated with HBV. The association was more prominent among older and Jewish patients. Patients with uveitis may benefit from screening for HBV. An association between uveitis and HCV has not been found.

Iris melanocytic tumours in New Zealand/Aotearoa: presentation, management and outcome in a high UV exposure environment. Eye (Lond) 2023; 37:692-699. [PMID: 35338357 PMCID: PMC9998588 DOI: 10.1038/s41433-022-02017-2] [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: 09/14/2021] [Revised: 02/09/2022] [Accepted: 03/04/2022] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND/OBJECTIVES Iris melanoma, a rare intraocular malignancy, represents the smallest subgroup of uveal melanoma. This first, comprehensive study of iris melanocytic lesions in the high ultraviolet environment in New Zealand/ Aotearoa (NZ) examines diagnosis, management and outcomes. SUBJECTS/METHODS Retrospective study of iris melanocytic tumours referred to tertiary referral centres in Auckland, NZ, over 20 years (1999-2018). Data analysed include demographics, tumour characteristics, histology, genetic analyses, treatment modalities, recurrence, metastasis, 5-year and overall survival. RESULTS Cohort (N = 51) was predominantly NZ European (98.0%) with no indigenous Māori, or Pasifika. Median age at presentation was 58 years. Tumours involved a median of two clock hours of iris. The posterior tumour margin extended to the anterior chamber angle in 22 patients (45.8%). Management included initial observation 54.9%, iridectomy/excision biopsy 29.4%, irido-cyclectomy 7.8%, plaque radiotherapy 7.8%, proton beam radiotherapy 7.8%, and ultimately enucleation 17.6%. Histology was performed in 19 cases (37%) with 16 confirmed melanomas (84%). Mean follow-up 4.2 years with median visual acuity of 6/7.5 two years post intervention. Melanoma-related metastasis and mortality occurred in two cases with five-year melanoma-related mortality of 2.0%. CONCLUSION In a climate with high ultraviolet exposure iris melanocytic tumours occurred almost exclusively in NZ Europeans, however, the majority of cases were category T1, possibly reflecting early diagnosis in the NZ health system. Nonetheless, >50% underwent surgery or radiotherapy, often utilising more than one modality. A high index of suspicion and early referral of iris melanocytic lesions should be considered in regions with high UV exposure.

Extrascleral extension of choroidal melanoma after iodine-125 brachytherapy treatment: a case series. Eye (Lond) 2023; 37:249-255. [PMID: 34987200 PMCID: PMC9873620 DOI: 10.1038/s41433-021-01861-y] [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: 03/31/2021] [Revised: 10/15/2021] [Accepted: 11/12/2021] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND/OBJECTIVES The purpose of this study is to report cases of choroidal melanoma that developed extrascleral tumour recurrence after treatment with iodine-125 brachytherapy. SUBJECTS/METHODS In this single-institution retrospective observational case series, all instances of biopsy-confirmed orbital melanoma after known intraocular melanoma were reviewed. Tumour characteristics, clinical course, time to recurrence, cytogenetics of initial tumour and recurrence, and presence of intraocular recurrence were documented. RESULTS Five cases of orbital melanoma following treatment with plaque radiotherapy are described. Tumour staging was Ia (1), IIa (2), and IIb (2). The primary lesion in four of the five appeared to have undergone complete regression for an average of 2 years, with the orbital melanoma developing after this interval. Recurrence of the intraocular tumour was seen in conjunction with an extrascleral component in two cases. Four cases ultimately underwent enucleation or exenteration; three had evidence of direct extension of tumour through the sclera. Four cases in this series had molecular characteristics associated with high metastatic risk (three patients with monosomy 3, one with BAP1 mutation). CONCLUSIONS High-risk tumour biology may predispose to late appearance of extrascleral melanoma despite optimal treatment and adequate control of the intraocular tumour. Extended follow-up with detailed orbital examination and imaging is recommended for this population.

TNF-alpha inhibitors biosimilar use in France: a nationwide population-based study using the French National Health Data System. Sci Rep 2022; 12:19569. [PMID: 36380105 PMCID: PMC9666557 DOI: 10.1038/s41598-022-24050-7] [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: 03/11/2022] [Accepted: 11/09/2022] [Indexed: 11/16/2022] Open
Abstract
TNF-alpha inhibitors have revolutionized the therapeutic care in chronic inflammatory diseases. Several biosimilar products were commercialized at their patent expiry, substantially decreasing the cost of treatment. This longitudinal descriptive study aimed at assessing infliximab, etanercept and adalimumab biosimilar penetration rates using data of the French National Health Data System. A total of 207,118 new or prevalent users from the date of first biosimilar commercialization in France (respectively January 2015, May 2016 and October 2018) were included in the study and followed until September 30, 2021. Biosimilars represented respectively 78%, 46% and 53% of the overall initiations, and 94%, 66% and 60% last year's initiations. A total of 46%, 19% and 17% of originator product prevalent users switched for a biosimilar during the follow-up. Biosimilar penetration rate was much higher for infliximab than for its counterparts, due to its hospital delivery modality. Biosimilar initiation and originator-to-biosimilar switch tended to be observed more in rheumatology than in the other specialties. Biosimilar use was mostly consistent across patient socio-demographic characteristics. Biosimilar initiation rate increased rapidly from their market arrival and originator-to-biosimilar switch rate remained moderate, highlighting the need and usefulness of political action and biosimilar use tracking.

Persistent intraocular Ebola virus RNA is associated with severe uveitis in a convalescent rhesus monkey. Commun Biol 2022; 5:1204. [PMID: 36352100 PMCID: PMC9644391 DOI: 10.1038/s42003-022-04158-2] [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: 11/17/2021] [Accepted: 10/24/2022] [Indexed: 11/11/2022] Open
Abstract
Despite increasing evidence that uveitis is common and consequential in survivors of Ebola virus disease (EVD), the host-pathogen determinants of the clinical phenotype are undefined, including the pathogenetic role of persistent viral antigen, ocular tissue-specific immune responses, and histopathologic characterization. Absent sampling of human intraocular fluids and tissues, these questions might be investigated in animal models of disease; however, challenges intrinsic to the nonhuman primate model and the animal biosafety level 4 setting have historically limited inquiry. In a rhesus monkey survivor of experimental Ebola virus (EBOV) infection, we observed and documented the clinical, virologic, immunologic, and histopathologic features of severe uveitis. Here we show the clinical natural history, resultant ocular pathology, intraocular antigen-specific antibody detection, and persistent intraocular EBOV RNA detected long after clinical resolution. The association of persistent EBOV RNA as a potential driver of severe immunopathology has pathophysiologic implications for understanding, preventing, and mitigating vision-threatening uveitis in EVD survivors. Deep characterization of uveitis in a rhesus monkey confirms Ebola virus RNA persistence is associated with severe immunopathology in the eye, with broader implications for the prevention and treatment of sight-threatening uveitis in human survivors of Ebola virus.

Ciclosporin A in bilateral auto-immune chronic posterior uveitis associated with macular oedema: a Long-term Observational Safety and Efficacy Study. Eye (Lond) 2022; 36:2144-2150. [PMID: 34718340 PMCID: PMC9581979 DOI: 10.1038/s41433-021-01829-y] [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: 05/12/2021] [Revised: 09/30/2021] [Accepted: 10/18/2021] [Indexed: 11/08/2022] Open
Abstract
OBJECTIVE A non-interventional, longitudinal, retrospective follow-up study to assess CsA-induced nephrotoxicity (IN) and its reversibility after withdrawal in patients exhibiting a bilateral chronic posterior uveitis (CPU) associated with cystoid macular oedema (CMO) in at least one eye. Data from medical records between 1986 and 2013. METHODS Primary outcome was the renal tolerance during and after CsA treatment assessed by plasma creatinine concentration and glomerular filtration rate (GFR) estimated by Chronic Kidney Disease Epidemiology (CKD-Epi) formula. Secondary outcomes were CsA through concentration, occurrence of cancers and ophthalmologic efficacy assessed by three parameters including CMO, vitreous inflammation, and best-corrected visual acuity BVCA changes. RESULTS One hundred forty-three patients were followed for renal tolerance. Underlying diseases were Birdshot retinochoroiditis (n = 67), Behçet disease (n = 9), probable sarcoidosis (n = 23), sympathetic ophthalmia (n = 3), idiopathic (n = 41). After CsA discontinuation in 115 patients (mean treatment duration of 5.9 ± 3.8 years) mean plasma creatinine concentration was 82.2 ± 14.2 µmol/L versus 82.1 ± 14.1 µmol/L at baseline, mean GFR was 79.4 ± 13.9 mL/min versus 82.5 ± 14.3 mL/min at baseline, with no significant difference (respectively p = 0.91 and p = 0.09). Blood pressure did not significantly change during follow-up. CMO was completely resorbed in at least one eye, in 70.8% patients (n = 72) at 6 months, in 71.4% patients (n = 49) at 10 years and in 54.2% patients (n = 24) at 20 years. BCVA did not statistically change over time. CONCLUSION Early and long-term monitoring of renal tolerance and dual adjustment of CsA doses in inflammatory stages of CPU were associated with reversible CsA IN. CsA could be effective in the treatment of CMO in CPU patients.

Familial Mediterranean fever associated frosted branch angiitis, retinal vasculitis and vascular occlusion. Eye (Lond) 2022; 36:2157-2162. [PMID: 34725467 PMCID: PMC9581995 DOI: 10.1038/s41433-021-01822-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 09/27/2021] [Accepted: 10/14/2021] [Indexed: 11/09/2022] Open
Abstract
OBJECTIVES To analyse the entity of retinal vasculitis, including frosted branch angiitis (FBA), or retina vascular occlusion in patients with familial Mediterranean fever (FMF). METHODS Retrospective collaborative case series using invitation by email to uveitis specialists around the Mediterranean basin. This series was combined with a literature review. Exclusion criteria included infectious diseases, Behçet's disease or other autoimmune diseases. RESULTS A total of 16 patients (21 eyes) had FMF and retinal vasculitis (FBA 11 patients, mild retinal vasculitis 5 patients). The mean age at onset of vasculitis was 29.5 ± 13.4 (range 9-62) with a female to male ratio of 9 to 7. In 19 eyes treated with various forms of corticosteroid and/or immunosuppression, the mean initial spectacle-corrected visual acuity improved from 6/194 to 6/10.5 at the last mean follow-up of 29.0 ± 34.9 months (p < 0.001). The most common FEVR mutations were M680I and M694V. In addition, retinal vascular occlusions included one case of central retinal artery occlusion and one case of branch retinal artery occlusion. CONCLUSION FBA and milder forms of retinal vasculitis are associated with FMF. Therapy involves an increase in colchicine dosage in early cases, a long period of oral corticosteroid, intravitreal dexamethasone implant or periocular corticosteroid in select cases, and combination therapy with systemic immunosuppression in severe cases. FMF needs to be included in the differential diagnosis of retinal vasculitis.

Abstract
The visualization of choroidal vasculature and innate immune cells in the eyes of pigmented mice has been challenging due to the presence of a retinal pigment epithelium (RPE) layer separating the choroid and retina. Here, we established methods for visualizing the choroidal macrophages, mast cells, and vasculature in eyes of albino and pigmented mice using cell type-specific staining. We were able to visualize the choroidal arterial and venous systems. An arterial circle around the optic nerve was found in mice similar to the Zinn-Haller arterial circle that exists in humans and primates. Three different structural patterns of choriocapillaris were observed throughout the whole choroid: honeycomb-like, maze-like, and finger-like patterns. Choroidal mast cells were relatively few but dense around the optic nerve. Mast cell distribution in the middle and periphery was different among strains. Macrophages were found in all layers of the choroid. Thus, utilizing the simple and reliable methods described herein will allow the evaluation of transgenic and preclinical mouse models of ocular diseases that affect the choroid, including age-related macular degeneration (AMD), diabetic choroidopathy, and retinopathy of prematurity. These studies will advance our understanding of the pathophysiology, and molecular and cellular mechanisms that can be targeted therapeutically, in these diseases.

Abstract
BACKGROUND/OBJECTIVES To record the prevalence of ocular sarcoidosis (OS) cases present in Northern Ireland as diagnosed using the International Workshop on Ocular Sarcoidosis (IWOS) classification, 2019. There are currently no data regarding OS in this population. SUBJECTS/METHODS Retrospective case review of OS cases as identified by IWOS criteria 2019. Mid-year population estimates were used to calculate disease prevalence. Additional data collected included uveitis features, ocular complications and the presence of ocular only or multi-system disease. RESULTS A total of 86 patients were identified meeting the criteria for a diagnosis of OS, and the prevalence of OS in Northern Ireland was estimated to be 4.5 cases per 100,000. The most common type of uveitis was panuveitis in 36% of cases, and the most common ocular complication was ocular hypertension in 36% of cases and detectable glaucomatous changes in 10%. Overall, 80% of cases presenting with ocular only sarcoidosis subsequently developed second organ involvement at a rate of 14%/person-years. The most common extra-ocular site of sarcoidosis was pulmonary. CONCLUSIONS The Northern Ireland population has a relatively high prevalence of OS compared with other European countries. OS presenting with only ocular involvement progressed to second organ involvement in 80% of patients at a rate of 14%/person-years. Raised intra-ocular pressure with or without glaucomatous damage was a frequent finding. Thoracic CT imaging should be requested if clinical suspicion of OS exists and the presence of lymphopenia has utility in diagnosis with concurrent use of systemic ACE inhibitors.

Abstract
PURPOSE To compare the time to resolution of perivascular infiltrates in tubercular retinal vasculitis (TRV) between anti-tubercular therapy (ATT) alone, and in combination with systemic corticosteroids. METHODS Observational retrospective cohort study in a tertiary eye centre in eastern India. Patients with TRV who were treated with anti-tubercular therapy (ATT) alone (Group A), or in combination with systemic corticosteroids (Group B) were included in the study. Eyes with additional inflammatory signs (cystoid macular oedema, vitritis ≥2+, optic disc oedema) were excluded. Resolution was defined as complete disappearance of perivascular infiltrates on seven-field fundus photographs. Descriptive statistics were used for demographic data. A linear mixed effects model was applied to adjust for intereye correlations, in patients with bilateral disease. The primary outcome measure was time to resolution of perivascular infiltrates. Secondary outcome measure was need for laser or surgical intervention for management of complications of TRV. RESULTS Fifty eyes of 39 patients (Group A 21/18 and Group B 29/21) were included. Both groups had similar demographics and severity of vasculitis. All patients had complete resolution of TRV. On adjusting for intereye correlation, the mean difference in time to resolution between the two groups (Group A, 3.24 [95% CI 2.69-3.77] months, and Group B, 4.76 [95% CI 3.52-5.99] months) was not statistically significant (0.96 weeks [-0.52 to 2.45] p = 0.21). Vaso-occlusive complications and healing patterns were similar in both groups. CONCLUSIONS ATT alone, may be sufficient for resolution of perivascular infiltrates, in TRV without additional inflammatory signs.

Abstract
OBJECTIVES To investigate the potential association between uveitis and an increased risk of developing inflammatory bowel disease (IBD). METHODS We conducted a retrospective cohort study by interrogating data from the Taiwan National Health Insurance Research Database entered between January 1, 2001 and December 31, 2013 to identify uveitis patients and age- and gender-matched controls. The cumulative incidence rates of subsequent IBD in the two groups were compared. The adjusted hazard ratio (HR) of IBD related to uveitis was generated by a multivariate cox regression model after adjustment for hypertension, diabetes, hyperlipidaemia, obesity and smoking. Furthermore, the HRs of the Crohn's disease (CD) and ulcerative colitis (UC) IBD subtypes were calculated separately. RESULTS A total of 198,923 subjects with uveitis and 397,846 controls were enroled. The mean age of the cohort was 47.7 ± 18.9 years. A significantly higher cumulative incidence of IBD was found in the uveitis group than in controls (4.13% vs. 1.48%, p < 0.0001). Under univariate cox regression analysis, uveitis patients had a significantly higher risk of IBD (HR = 1.47; 95% confidence interval (CI): 1.43-1.52, p < 0.0001). The association remained significant in the multivariate regression model, with an adjusted HR of 1.44 (95% CI: 1.39-1.49, p < 0.0001). Moreover, in subgroup analysis, uveitis was significantly associated with an increased risk of Crohn's disease (adjusted HR = 1.49; 95% CI: 1.44-1.54), but not with ulcerative colitis (adjusted HR = 1.03; 95% CI: 0.92-1.15). CONCLUSIONS Patients with uveitis are at significantly greater risk of developing IBD than individuals without uveitis.

Abstract
INTRODUCTION To investigate the incidence and causes of intraoperative choroidal detachment (CD) during small-gauge vitrectomy, as well as the anatomic and visual outcomes. METHODS We retrospectively reviewed the medical records of 1026 consecutive patients who underwent small-gauge vitrectomy from June 2017 to December 2018 at Zhongshan Ophthalmic Centre, Guangzhou, China. Data on the presence, location, and extent of intraoperative CD and its relationship to the infusion cannula were collected. Patient demographic characteristics and postoperative anatomic and visual outcomes were also assessed. RESULTS A total of six cases were found to have intraoperative CD, including two with serous CD, three with limited haemorrhagic CD, and one with CD caused by inadvertent perfusion of gas during air/fluid exchange. Retraction of the infusion cannula and acute ocular hypotony were found to be the main causes of intraoperative CD in five out of the six cases. The best-corrected visual acuity of all cases significantly improved after the surgery. CONCLUSION The incidence of intraoperative CD during small-gauge vitrectomy is low; the predominant causes are retraction of the infusion cannula and acute ocular hypotony. Immediate awareness and timely closure of the incision may contribute to a better surgical prognosis.

Abstract
OBJECTIVE To define the swept-source optical coherence tomography (SS-OCT) features which distinguish ocular toxoplasmosis (OT) from other forms of retinochoroiditis. METHODS This is a prospective diagnostic study enrolling 43 eyes of 43 patients with active toxoplasmic (TOXO) retinochoroiditis matched to 54 eyes (54 lesions) with non-TOXO retinochoroiditis evaluated by structural SS-OCT. RESULTS The finding of retinal hyper-reflective round deposits, sub-lesional choroidal thickening, and sub-lesional retinal pigment epithelium elevation were more likely to be found in TOXO lesions with a positive likelihood ratio of 45.2 (95% CI: 6.45-316.56), 23.86 (95% CI: 6.09-93.36), and 9.79 (95% CI: 4.22-22.7), respectively. The presence of each of these findings was associated with a high level for positive predictive value (PPV) (88.63-97.29), negative predictive value (NPV) (88.3-92.45), sensitivity (83.72-90.69), and specificity (90.74-98.14). Two-parameter model binary logistic regression suggested that sub-lesional retinal pigment epithelium elevation and sub-lesional choroidal thickening were significant predictors of the diagnosis of OT (Wald = 11.905, p < 0.001; Wald = 14.881, p < 0.001; respectively). By adding hyper-reflective round deposits along the posterior hyaloid or the retinal surface the model improved its performance with very good diagnostic accuracy with area under the curve (AUC) values of 0.96 (95% CI: 0.9-0.99) for two parameters model and 0.98 (95% CI: 0.93-0.99) for the three parameters model. CONCLUSIONS Our results show that three OCT findings including retinal hyper-reflective round deposits, sub-lesional choroidal thickening, and sub-lesional retinal pigment epithelium elevation are more likely to occur in OT patients as compared with non-OT patients.

BACKGROUND Choroidal tuberculoma is possibly the most unequivocal manifestation of ocular infection with Mycobacterium tuberculosis. Here, we investigate the need for adjunctive corticosteroids in the management of this infection. We have compared the efficacy of anti-tubercular therapy (ATT) with or without oral corticosteroids, in management of choroidal tuberculoma. METHODS We report a retrospective, observational study of patients treated with ATT for choroidal tuberculoma. Group A patients were treated with standard 6-month ATT alone, and Group B with ATT and oral corticosteroids, with/without intravitreal triamcinolone/ bevacizumab injections. Primary outcome measure was time to complete resolution of lesions. Secondary measures were time to first sign of resolution and change in best corrected visual acuity (BCVA) at final visit. RESULTS Fourteen patients were included in the study-seven in Group A and seven in Group B. Both groups had similar duration of symptoms and size of lesions but not baseline BCVA (p = 0.02). Perilesional fluid was noted in all eyes in each group. Mean time to complete resolution in group A was 1.89 ± 0.28 (range 1.25-2) months, significantly lesser than group B (5.17 ± 2.64 [range 2-9] months, p = 0.005, Mann-Whitney test). Mean time to first sign of resolution (range from 5 days to 10 weeks, p = 0.35) and mean change in BCVA between presentation and final follow up (p = 0.2) were comparable between both groups. CONCLUSION Anti-TB monotherapy alone, may be sufficient for resolution of at least, select cases of choroidal tuberculoma, without the need for adjunctive corticosteroids.

Precise, simplified diagnostic criteria and optimised management of initial-onset Vogt-Koyanagi-Harada disease: an updated review. Eye (Lond) 2022; 36:29-43. [PMID: 34145419 PMCID: PMC8727674 DOI: 10.1038/s41433-021-01573-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Revised: 04/13/2021] [Accepted: 04/21/2021] [Indexed: 02/06/2023] Open
Abstract
Vogt-Koyanagi-Harada (VKH) disease is a primary autoimmune stromal choroiditis. This review aimed to provide a novel perspective of the disease. We took into account recent developments in the understanding of the disease and crucial progress in investigational modalities of the choroid, which has led to new, simpler diagnostic criteria. We analysed recent novel notions in the literature and new diagnostic tools for VKH. We identified the following updates for VKH disease: (1) A crucial differentiation between the acute initial-onset and the chronic forms of the disease; (2) the integration of new, precise imaging methods to assess choroidal inflammation; (3) the promotion of simplified, more reliable diagnostic criteria for acute initial-onset of the disease, based on the sine qua non presence of diffuse choroiditis, detected with indocyanine green angiography (ICGA) and/or Enhanced Depth Imaging OCT (EDI-OCT); and (4) treatment optimisation through early, vigorous, sustained corticosteroid and nonsteroidal immunosuppression, as the first line of treatment for initial-onset VKH disease, and monitoring subclinical choroidal inflammation during follow-ups. Several studies have shown that most patients could discontinue treatment without an inflammation relapse. ICGA and EDI-OCT represented the methods of choice for precisely monitoring disease evolution. Simplified, precise, new diagnostic criteria allow early diagnosis of VKH. In VKH disease, inflammation exclusively originates in the choroidal stroma. Therefore, in many cases, early, sustained treatment, with dual corticosteroid and nonsteroidal immunosuppressive therapy can result in full "healing", which obviates chronic, uncontrolled, subclinical choroidal inflammation.

Systemic corticosteroid use in UK Uveitis practice: results from the ocular inflammation steroid toxicity risk (OSTRICH) study. Eye (Lond) 2021; 35:3342-3349. [PMID: 33531696 PMCID: PMC8602319 DOI: 10.1038/s41433-020-01336-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 11/18/2020] [Accepted: 11/23/2020] [Indexed: 11/09/2022] Open
Abstract
OBJECTIVES To ascertain adherence to an international consensus target of ≤7.5 mg/day of prednisolone for maintenance systemic corticosteroid (CS) prescribing in uveitis and report the frequency of courses of high-dose systemic CS in the UK. METHODS We conducted a national, multicentre audit of systemic CS prescribing for uveitis at 11 UK sites between November 2018 and March 2019. High-dose CS was defined as (1) maintenance >7.5 mg prednisolone for >3 consecutive months, or (2) >1 course ≥40 mg oral CS or ≥500 mg intravenous (IV) methylprednisolone in the past 12 months. Case notes of patients exceeding threshold CS doses were reviewed by an independent uveitis specialist and judged as avoidable or not, based upon a scoring matrix. RESULTS Of 667 eligible patients, 285 (42.7%) were treated with oral or IV CS over the preceding 12 months; 96 (33.7%) of these exceeded the threshold for high-dose CS. Twenty-five percent of prescribing in patients on excess CS was judged avoidable; attributed to either prescribing long-term CS without evidence of consideration of alternative strategies, prescribing error or miscommunication. More patients received immunomodulatory therapy (IMT) in the group treated with CS above threshold than below threshold (p < 0.001) but there was no significant difference in doses of IMT. CONCLUSION 33% of patients had been prescribed excessive corticosteroid when compared to the reference standard. An analysis of decision-making suggests there may be opportunity to reduce excess CS prescribing in 25% of these patients.

Abstract
BACKGROUND/OBJECTIVES To assess the ratio of scarred/active areas of fundus lesions in patients with presumed ocular toxoplasmosis. SUBJECTS/METHODS Retrospective monocentric study of patients with presumed ocular toxoplasmosis seen between May 2004 and February 2018. Patients with a positive anti-Toxoplasma serology presenting characteristic fundus lesions. Cases with images of both baseline active and scarred lesions of the fundus were included. The borders of each active or scarred lesion were delineated on colour photographs by two independent observers and the area of the lesions was calculated using Digimizer 4.2.2 (MedCalc Software, Ostend, Belgium). The interobserver variability of the measures was recorded and their means were used for further calculations. To study the ratio of the area of scarred retinochoroiditis over the area of the baseline active lesion (R). RESULTS A total of 171 cases (83 males, 88 females) with a mean age of 31.6 ± 13.8 years were included. The average areas of active and scarred retinochoroiditis were, respectively, 1.32 ± 1.59 and 1.79 ± 2.36 optic disc area. The average ratio between scarred and active areas of retinochoroiditis was 1.36 [range 0.54-2.18]. The administration of a systemic treatment [R = 1.25, p = 0.003], the absence of a pre-existing scar [R = 1.05, p < 0.001] and a peripapillary location of the lesion [R = 0.85, p < 0.001] were each significantly associated with smaller scarred/active area ratios. CONCLUSIONS We assessed in a standardized manner the ratio of scarred/active areas of toxoplasmic lesions and showed that the area of scarred lesions was on average slightly larger than the area of active retinochoroiditis.

Human U90926 orthologous long non-coding RNA as a novel biomarker for visual prognosis in herpes simplex virus type-1 induced acute retinal necrosis. Sci Rep 2021; 11:12164.

Abstract
Acute retinal necrosis (ARN) is a form of infectious uveitis caused by alpha herpesviruses, including herpes simplex virus type 1 (HSV-1). We previously found that the long non-coding RNA (lncRNA) U90926 is upregulated in murine retinal photoreceptor cells following HSV-1 infection, leading to host cell death. However, to date, an orthologous transcript has not been identified in humans. We investigated U90926 orthologous transcript in humans and examined its utility as a prognostic marker for visual acuity in patients with ARN. We identified two human orthologous transcripts (1955 and 592 bases) of lncRNA U90926. The amount of the longer human U90926 transcript was approximately 30- and 40-fold higher in the vitreous fluid of patients with ARN than in those with sarcoidosis and intraocular lymphoma, respectively. Furthermore, the expression of the longer human U90926 transcript in the vitreous fluid was highly correlated with the final best-corrected logarithm of the minimum angle of resolution visual acuity in patients with ARN (r = 0.7671, p = 0.0079). This suggests higher expression of the longer human U90926 transcript in the vitreous fluid results in worse visual prognosis; therefore, expression of the longer human U90926 transcript is a potential negative prognostic marker for visual acuity in patients with ARN.

Advances and potential new developments in imaging techniques for posterior uveitis. Part 1: noninvasive imaging methods. Eye (Lond) 2021; 35:33-51. [PMID: 32678354 PMCID: PMC7852509 DOI: 10.1038/s41433-020-1063-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 06/18/2020] [Accepted: 06/19/2020] [Indexed: 12/22/2022] Open
Abstract
The aim of this review was to identify the imaging methods at our disposal to optimally manage posterior uveitis at the present time. The focus was put on methods that have become available since the 1990s, some 30 years after fluorescein angiography had revolutionized imaging of posterior uveitis in particular imaging of the retinal vascular structures in the 1960s. We have focussed our review on precise imaging methods that have been standardized and validated and can be used universally thanks to commercially produced and available instruments for the diagnosis and follow-up of posterior uveitis. The first part of this imaging review will deal with noninvasive imaging methods, focusing on fundus autofluorescence and optical coherence tomography as well as recent developments in imaging of the posterior segment.

AAV-mediated expression of HLA-G1/5 reduces severity of experimental autoimmune uveitis. Sci Rep 2019; 9:19864. [PMID: 31882729 PMCID: PMC6934797 DOI: 10.1038/s41598-019-56462-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Accepted: 12/04/2019] [Indexed: 12/21/2022] Open
Abstract
Non-infectious uveitis (NIU) is an intractable, recurrent, and painful disease that is a common cause of vision loss. Available treatments of NIU, such as the use of topical corticosteroids, are non-specific and have serious side effects which limits them to short-term use; however, NIU requires long-term treatment to prevent vision loss. Therefore, a single dose therapeutic that mediates long-term immunosuppression with minimal side effects is desirable. In order to develop an effective long-term therapy for NIU, an adeno-associated virus (AAV) gene therapy approach was used to exploit a natural immune tolerance mechanism induced by the human leukocyte antigen G (HLA-G). To mimic the prevention of NIU, naïve Lewis rats received a single intravitreal injection of AAV particles harboring codon-optimized cDNAs encoding HLA-G1 and HLA-G5 isoforms one week prior to the induction of experimental autoimmune uveitis (EAU). AAV-mediated expression of the HLA-G-1 and -5 transgenes in the targeted ocular tissues following a single intravitreal injection of AAV-HLA-G1/5 significantly decreased clinical and histopathological inflammation scores compared to untreated EAU eyes (p < 0.04). Thus, localized ocular gene delivery of AAV-HLA-G1/5 may reduce the off-target risks and establish a long-term immunosuppressive effect that would serve as an effective and novel therapeutic strategy for NIU, with the potential for applications to additional ocular immune-mediated diseases.
