[PMID: 38907787 DOI: 10.1007/s10792-024-03177-8] [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: 01/12/2024] [Accepted: 06/15/2024] [Indexed: 06/24/2024]
Abstract
PURPOSE To identify risk factors influencing visual outcomes in patients with pathological myopia-associated choroidal neovascularization (PM-CNV) following intravitreal injections of conbercept. METHODS A total of 86 eyes from 86 patients received intravitreal conbercept in a 1 + PRN regimen. After the initial injection, patients were followed for 12 months. They were categorized into two groups based on their 12-month visual acuity change: those who achieved greater than a one-line improvement in BCVA (improved group; n = 65) and those who experienced a one-line or lesser improvement or a decrease in BCVA (non-improved group; n = 21). RESULTS Over the 12-month period, the mean BCVA in the improved group significantly improved from 0.82 to 0.41 LogMAR. In the non-improved group, BCVA changed from 1.24 to 1.09 LogMAR. Similarly, the mean CRT decreased from 426.21 μm at baseline to 251.56 μm at 12 months in the improved group, and from 452.47 to 382.45 μm in the non-improved group. Multivariable logistic regression analyses revealed that older age (OR 1.287; 95% CI 1.019-1.625; P = 0.034), poorer baseline BCVA (OR 6.422; 95% CI 1.625-25.384; P = 0.008), the presence of subfoveal CNV (OR 4.817; 95% CI 1.242-18.681; P = 0.023), and organized interlacing patterns of CNV morphology (OR 5.593; 95% CI 1.397-22.392; P = 0.015) emerged as independent risk factors correlated with worsened visual prognosis following intravitreal conbercept injections. CONCLUSIONS Conbercept demonstrates significant efficacy and safety in treating PM-CNV. Key factors influencing visual recovery post-treatment include older age, poorer baseline BCVA, the presence of subfoveal CNV, and organized interlacing patterns of CNV morphology.

Abstract
PURPOSE To assess the clinical outcomes of two intravitreal injection regimens of Conbercept used to treat choroidal neovascularization secondary to pathological myopia (PM-CNV). METHODS A total of 72 eyes of 72 patients were treated: 39 eyes received a single injection followed by treatment pro re nata (1 + PRN); 33 eyes first received 3 consecutive monthly injections (3 + PRN) then followed by PRN. After initial injection, patients were followed up for 12 months. RESULTS The mean age of 72 patients was 45.3 ± 5.1 years, with the mean diopter of -10.62 ± 3.24D. The best corrected visual acuity (BCVA) was 0.86 ± 0.23 LogMAR with 1 + PRN and 0.90 ± 0.19 LogMAR with 3 + PRN at baseline (P = 0.422), 0.36 ± 0.07 and 0.33 ± 0.05 LogMAR at month 3 (P = 0.026); and 0.33 ± 0.03 and 0.32 ± 0.02 LogMAR at month 12 (P = 0.096). The central retinal thickness (CRT) was 333.5 ± 22.7 μm with 1 + PRN and 341.2 ± 20.9 μm with 3 + PRN at baseline (P = 0.139), 281.53 ± 10.28 and 273.15 ± 13.24 μm at month 3 (P = 0.004); 266.83 ± 8.14 and 264.91 ± 9.27 μm at month 12 (P = 0.350). The number of injections in the 1 + PRN group was significantly lower than that observed in the 3 + PRN group (2.15 ± 1.06 versus 3.36 ± 0.74; P < 0.001). During the follow-up, no serious ocular complications and adverse reactions related to Conbercept and injections occurred. CONCLUSIONS Both injection regimens resulted in similar visual outcomes in PM-CNV patients. The 1 + PRN regimen had fewer injections and might be more suitable in this patient population.

Br J Ophthalmol 2023; 107:1043-1050. [PMID: 35264328 PMCID: PMC10359589 DOI: 10.1136/bjophthalmol-2021-320318] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 02/21/2022] [Indexed: 11/04/2022]
Abstract
BACKGROUND Informed decisions on myopia management require an understanding of financial impact. We describe methodology for estimating lifetime myopia costs, with comparison across management options, using exemplars in Australia and China. METHODS We demonstrate a process for modelling lifetime costs of traditional myopia management (TMM=full, single-vision correction) and active myopia management (AMM) options with clinically meaningful treatment efficacy. Evidence-based, location-specific and ethnicity-specific progression data determined the likelihood of all possible refractive outcomes. Myopia care costs were collected from published sources and key informants. Refractive and ocular health decisions were based on standard clinical protocols that responded to the speed of progression, level of myopia, and associated risks of pathology and vision impairment. We used the progressions, costs, protocols and risks to estimate and compare lifetime cost of myopia under each scenario and tested the effect of 0%, 3% and 5% annual discounting, where discounting adjusts future costs to 2020 value. RESULTS Low-dose atropine, antimyopia spectacles, antimyopia multifocal soft contact lenses and orthokeratology met our AMM inclusion criteria. Lifetime cost for TMM with 3% discounting was US$7437 (CI US$4953 to US$10 740) in Australia and US$8006 (CI US$3026 to US$13 707) in China. The lowest lifetime cost options with 3% discounting were antimyopia spectacles (US$7280, CI US$5246 to US$9888) in Australia and low-dose atropine (US$4453, CI US$2136 to US$9115) in China. CONCLUSIONS Financial investment in AMM during childhood may be balanced or exceeded across a lifetime by reduced refractive progression, simpler lenses, and reduced risk of pathology and vision loss. Our methodology can be applied to estimate cost in comparable scenarios.

Abstract
Purpose To evaluate the clinical characteristics of myopic choroidal neovascularization (mCNV) according to peripapillary atrophy (PPA) and optic disk tilt and to explore whether those myopic disk deformations are associated with the prognosis of mCNV. Methods Patients with subfoveal mCNV who received intravitreal bevacizumab injection and followed for ≥3 years were included. PPA was quantified as area of the ß-zone PPA/disk area ratio (PDR) and optic disk tilt as the tilt ratio (the longest/shortest disk diameter). We compared the clinical characteristics in terms of PDR and tilt ratio and identified the poor prognostic factors using Logistic regression and Cox proportional hazard model. Results Among 80 eyes of 80 patients, 29 (36.30%) eyes developed macular atrophy during 80.71 ± 34.76 months. PDR and tilt ratio are strongly correlated with each other (P = 0.004). Higher PDR showed significant correlations with longer axial length (P = 0.013), worse baseline and final VA (P = 0.007 and P = 0.047), and thinner subfoveal choroidal thickness (P = 0.039), while higher tilt ratio showed significant correlations only with longer axial length (P = 0.036). High PDR was also an independent risk factor for both macular atrophy (OR = 2.257, P < 0.001) and poor visual outcome (HR = 1.174, P = 0.007), while high disk tilt ratio was not. Conclusion Subfoveal mCNV with higher ß-zone PPA area/disk area ratio had worse functional and structural outcomes.

Abstract
BACKGROUND Myopic maculopathy (MM) has become a major cause of visual impairment and blindness worldwide, especially in East Asian countries. Deep learning approaches such as deep convolutional neural networks (DCNN) have been successfully applied to identify some common retinal diseases and show great potential for the intelligent analysis of MM. This study aimed to build a reliable approach for automated detection of MM from retinal fundus images using DCNN models. METHODS A dual-stream DCNN (DCNN-DS) model that perceives features from both original images and corresponding processed images by color histogram distribution optimization method was designed for classification of no MM, tessellated fundus (TF), and pathologic myopia (PM). A total of 36,515 gradable images from four hospitals were used for DCNN model development, and 14,986 gradable images from the other two hospitals for external testing. We also compared the performance of the DCNN-DS model and four ophthalmologists on 3000 randomly sampled fundus images. RESULTS The DCNN-DS model achieved sensitivities of 93.3% and 91.0%, specificities of 99.6% and 98.7%, areas under the receiver operating characteristic curves (AUC) of 0.998 and 0.994 for detecting PM, whereas sensitivities of 98.8% and 92.8%, specificities of 95.6% and 94.1%, AUCs of 0.986 and 0.970 for detecting TF in two external testing datasets. In the sampled testing dataset, the sensitivities of four ophthalmologists ranged from 88.3% to 95.8% and 81.1% to 89.1%, and the specificities ranged from 95.9% to 99.2% and 77.8% to 97.3% for detecting PM and TF, respectively. Meanwhile, the DCNN-DS model achieved sensitivities of 90.8% and 97.9% and specificities of 99.1% and 94.0% for detecting PM and TF, respectively. CONCLUSIONS The proposed DCNN-DS approach demonstrated reliable performance with high sensitivity, specificity, and AUC to classify different MM levels on fundus photographs sourced from clinics. It can help identify MM automatically among the large myopic groups and show great potential for real-life applications.

Abstract
INTRODUCTION Myopic choroidal neovascularization (mCNV) often causes serious damage to central vision. The mechanisms behind it remain unclear. METHOD In this study, monocular form deprivation was applied to induce high myopia and 532 nm laser was employed to induce CNV in guinea pig. The development of neovascularization was measured comprehensively by fundus fluorescein angiography, Optical coherence tomography and HE-staining. Gene expression was detected by real-time polymerase chain reaction and Immunohistochemistry. RESULTS The proliferation of new blood vessels increased with time and peaked at 21 d. At each time point after laser photocoagulation, the incidence of CNV was higher in form-deprived myopia (FDM) group than in control group. Myopic CNV started earlier and decreased more slowly. The obvious continuous fluorescein leakage could last as long as one month. The expressions of hypoxia-inducible factor (HIF)-1α and vascular endothelial growth factor (VEGF) increased and peaked at 14 d in both groups after laser photocoagulation. Moreover, after laser photocoagulation, miR-21 expression was upregulated in both groups, reached a peak at 7 d, with a level much higher in FDM group. In addition, miR-21 expression was positively correlated with VEGF and HIF-1α expression in both groups. CONCLUSION miR-21 correlated with HIF-1α-VEGF signaling pathway may promote CNV formation in high-myopia guinea.

Abstract
PURPOSE Measurement of macular pigment optical density (MPOD) can be conducted to assist in the diagnosis of multiple fundus diseases. METHODS Fifty-four subjects with high myopia were prospectively recruited for a 3-month clinical trial. Detailed ophthalmologic examinations and MPOD measurements were performed. The subjects in each high myopia category group were randomly subdivided into 5 intervention groups, including a low-dose Lycium barbarum group (10 g Lycium barbarum, containing 10 mg of zeaxanthin and 1 mg of lutein), low-dose control group (1 mg of lutein), high-dose Lycium barbarum group (20 g of Lycium barbarum, containing 20 mg of zeaxanthin and 2 mg lutein), high-dose control group (2 mg of lutein), and a blank control group. Differences in the MPODs among the high myopia groups were calculated with Welch two-sample t tests. A linear mixed-effects model was constructed and Pearson's correlation analysis was performed to determine correlations between MPOD and other factors. The MPOD values at baseline and the 3-month follow-up were compared with the Mann-Whitney test. RESULTS The category 1 group had a significantly higher MPOD than the category 2 (P = 0.02) and category 3 groups (P < 0.001). The category 2 group had a significantly higher MPOD than the category 3 group (P < 0.001). The MPOD significantly decreased with increasing axial length (AL) and decreasing best-corrected visual acuity (BCVA) in the category 1-3 groups and with increasing age and increasing intraocular pressure (IOP) in the category 2-3 groups. The MPOD was significantly higher in the group who received high-dose zeaxanthin from Lycium barbarum than in the group who received high-dose lutein at 3 months (P = 0.0403), while no significant difference was identified between the low-dose zeaxanthin group and low-dose lutein group (P = 0.1117). CONCLUSIONS The MPOD was negatively correlated with the category of high myopia. Supplementation of zeaxanthin from Lycium barbarum is beneficial in preventing the loss of macular pigment of high myopia patients.

Abstract
AIM To investigate therapeutic effects of traditional Chinese medicine formulations, Hexuemingmu (HXMM) on laser-induced choroidal neovascularization (CNV) and follow-up effect in mice. METHODS C57BL/6 mice of 8-week-old were used and CNV was induced with 577 nm laser photocoagulation. Animals were randomly divided into groups and different doses of HXMM were administered daily. One, four, and eight weeks after the intervention, the electroretinogram (ERG), fundus fluorescence angiography, choroidal flat mount and immunofluorescence staining were preformed to evaluate the function and CNV formation. The expression levels of angiogenic proteins were determined by Western blotting and immunofluorescence staining. An analysis of variance and Kruskal-Wallis test were used to test the differences among the groups. RESULTS The results showed that HXMM effectively increased amplitude of ERG of mice (P<0.05), alleviated fundus CNV leakage (P<0.05), and reduced the area of neovascularization and the expression of angiogenic proteins (P<0.05) after laser-induced CNV. CONCLUSION HXMM can protect the retinal function of mice after laser-induced CNV, and inhibit the CNV development.

Abstract
PURPOSE To validate the recently developed ATN grading system for myopic maculopathy to classify eyes with pathologic myopia. METHODS Cross-sectional study. A series of consecutive eyes diagnosed with pathologic myopia and signs of myopic maculopathy (grade ≥1 for atrophic, tractional, or neovascular components of the ATN), with a refractive error > -6.0 diopters (D), were included. All patients underwent complete ophthalmological examination including fundus photography and swept-source optical coherence tomography. Six observers graded each eye twice using the ATN system (≥15 days between assessments) based only on the aforementioned data. RESULTS Sixty eyes from 47 patients (61.7% female) were graded. Mean patient age was 63.2 ± 11.7 years. The mean spherical equivalent was -13.8 ± 6.5 D. Mean axial length was 28.6 ± 2.16 mm. Overall, the mean intraobserver agreement (%) for the same image was 92.0%, and the mean interobserver agreement for the second image was 77.5%. The weighted Fleiss k showed excellent correlation (k > 0.8) for the traction and neovascularization components and good correlation (0.75) for atrophy. Interobserver agreement for each of these three components was 95.2%, 98.4%, 95.0%, respectively. CONCLUSION Application of the ATN resulted in high intraobserver and interobserver correlation, underscoring the reproducibility of the system.

[PMID: 34277654 PMCID: PMC8282923 DOI: 10.3389/fmed.2021.655822] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 06/08/2021] [Indexed: 11/13/2022] Open
Abstract
The global prevalence of myopia has brought to the attention of the different eye and vision specialists, who make way to control its progression. Evidence have shown that a proactive reshaping of the eyeball is the core point of myopia developing process, which particularly includes the weakening, thinning, and expanding of the sclera. Thus, the sclera is considered to be a prime target for therapeutic manipulation in halting progressive myopia. In the past decades, corneal collagen cross-linking has been applied in clinical practice for treating aberrant corneal remodeling diseases. In this article, we hypothesize that scleral collagen cross-linking (SXL) has a huge potential in stabilizing myopic process by shaping the eyeball and preventing the aberrant scleral remodeling. In contrast with the current methods of optometry correction, such as physiotherapy, pharmacotherapy, spectacles, contact lenses, refractive surgeries, etc., eyeball-shaping method using SXL is a fundamental intervention which aims at the pathogenesis of progressive visual loss of myopia. Compared with the current posterior scleral reinforcement, the most advantage of SXL is that there is no allotransplant into the myopic eye, which means less expenditure, lower risk, and easier to handle in operating.

Abstract
PURPOSE To analyze clinical characteristics in eyes with myopic traction maculopathy (MTM). METHODS Nine hundred and ninety-one patients (1,334 eyes) with MTM, who visited Zhongshan Ophthalmic Center from January 2014 to December 2019, were involved. Myopic traction maculopathy was classified into six grades according to the new classification system: no macular schisis (T0), inner or outer foveoschisis (FS) (T1); inner and outer FS (T2), foveal detachment (T3), full-thickness macular hole (T4), and macular hole retinal detachment (T5). RESULTS Seven hundred and seventy-eight (58.32%) eyes were in T0, 157 (11.77%) in T1, 177 (13.27%) in T2, 129 (9.67%) in T3, 45 (3.37%) in T4, and 48 (3.67%) in T5. With the severity of MTM, age increased and the best-corrected visual acuity became worse (P < 0.001). However, no significant differences were found on spherical equivalent refraction or axial length among different grades of MTM (P > 0.05). Moreover, significant differences on best-corrected visual acuity, spherical equivalent refraction, axial length, and staphyloma rate existed between eyes with inner FS and eyes with outer FS (P < 0.01), but not between eyes with outer FS and eyes with both inner FS and outer FS (P > 0.05). Besides, significant differences were found on spherical equivalent refraction, axial length, and staphyloma rate between full-thickness macular hole with and without macular schisis (P < 0.001). CONCLUSION Spherical equivalent refraction and axial length were not correlated with the severity of MTM in this cohort. It might be preferable to categorize eyes with outer FS and eyes with both inner FS and outer FS as a same grade. Potential difference in the pathogenesis between full-thickness macular hole with and without macular schisis might exist.

Abstract
Aim Evaluation of real-world outcomes of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy in the primary treatment of choroidal neovascularization (CNV) secondary to pathological myopia. Patients and Methods A retrospective cohort analysis of treatment naive patients with myopic CNV who received treatment with either intravitreal ranibizumab or aflibercept over a 12-year period from September 2007 to May 2020 was performed. Baseline features, treatment factors and outcomes were compared between younger and older patients and final visual outcome was assessed for associated factors. Results Thirty-seven eyes of 36 patients (24 females, 12 males) were included. Mean age was 58 years (range=26–89 years). Of these patients, 11/36 (31%) were ≤50 years of age and 25/36 (69%) were ≥51 years of age. Seventy-three percent (27/37) of eyes were phakic. One patient received bilateral treatment for myopic CNV. Median spherical equivalent was −8.50 diopters. Seventy percent (26/37) of eyes commenced primary treatment with ranibizumab, and 11/37 (30%) eyes commenced treatment with aflibercept. There were no significant differences between treatment factors and outcomes of younger and older patients. Median number of injections was 3 over a median follow-up period of 24.6 months. Mean CRT decreased by 126μm and median visual improvement was +6 letters. Analysis showed that younger age (p=0.022) and fewer injections (p=0.004) were associated with better visual outcomes. Conclusion Myopic CNV requires less frequent anti-VEGF intravitreal therapy over a shorter follow-up period than both neovascular age-related macular degeneration and diabetic macular edema. Increased frequency of administration of intravitreal anti-VEGF treatment did not improve vision. Younger age is associated with a better final visual outcome. These findings may help to advise patients about the prognosis of treatment and help guide treatment decisions.

Abstract
PURPOSE The purpose of this study was to analyze the progression of macular Bruch membrane defects (BMD) in highly myopic patients with patchy atrophy (PA); and study its correlation with the enlargement of PA and ATN grading. Setting/Venue: Puerta de Hierro-Majadahonda University Hospital, Madrid, Spain. PATIENTS AND METHODS This was a cross-sectional, noninterventional study. A series of 451 highly myopic eyes with spherical equivalent > -6.0 D and/or >26 mm of axial length (AL) were included. All patients underwent a complete ophthalmological examination and swept-source optical coherence tomography (SS-OCT), and were graded using the ATN system by 2 masked retina experts that assessed the atrophic (A), tractional (T), and neovascular (N) components. SS-OCT b-scans were employed to study PA and macular BMD at baseline and at a 1-year follow-up, in patients with good foveal fixation. RESULTS Out of total 451 eyes, 126 eyes (27.9%) had PA (53 patients; 75.4% women). Mean T and N in eyes with PA were 1.1 ± 1.3 and 0.08 ± 0.2, respectively. Sixty-eight of them had >1-year follow-up with a good foveal fixation and enough image quality. From them, BMD were found in 44 eyes (64.7%) at baseline and increased to 59 eyes (86.7%) at a 1-year follow-up. The mean great linear dimension of PA and macular BMD increased with a median of 384.5 ± 462.5 μm (IR 68.0-660.2) and 265.6 ± 418.1 μm (IR 0-331.7), respectively. At 1-year, PA and BMD sizes increase, and were statistically significant (p < 0.001). There was a positive correlation between the growth of macular BMD and the growth of PA (r = 0.490, p < 0.00). T grading correlated significantly with PA growth (p < 0.05). CONCLUSIONS Macular BMD increase its prevalence and its size over time in highly myopic patients with PA. There is a positive correlation between BMD and PA area growth. New studies with a larger sample size, longer follow-up, and AL elongation correlation are necessary to corroborate our findings.

Abstract
AIM To evaluate the global trends in and explore hotspots of high myopia (HM) research. METHODS This bibliometric analysis was used to reveal the publication trends in HM research field based on the Web of Science Core Collection (WoSCC). VOSviewer version 1.6.13 software was used to analyze the data and construct a knowledge map including the yearly publication number, journals, countries, international collaborations, authors, research hotspots, and intellectual base in HM. RESULTS The search engine found 3544 peer-reviewed publications on HM between 2010 and 2019, and the yearly research output substantially elevated over the past decade. China is the top publishing country, and Sun Yat-sen University was the most active academic institution. Jonas JB is the top publishing scientist, and Investigative Ophthalmology and Visual Science (IOVS) was the most productive journal. The highest cited references mainly focused on epidemiology and management. The keywords formed 6 clusters: 1) refractive surgery; 2) etiology and clinical characteristics; 3) the mechanism of eye growth; 4) management for myopic maculopathy; 5) vitrectomy surgical treatment; 6) myopia-associated glaucoma-like optic neuropathy. CONCLUSION The evaluation of development trends based on the data extracted from WoSCC can provide valuable information and guidance for ophthalmologists and public health researchers to improve management procedures in HM field.

Abstract
Complications from pathologic myopia (PM) are a major cause of visual impairment and blindness. However, an efficient clinical therapeutic strategy for PM is still lacking. The aim of this study was to quantitatively compare the proteomic profiles of aqueous humor between PM and non-PM cataract patients. Twenty aqueous humor samples from each group were analyzed with label-free quantitative proteomic analysis to identify the differentially expressed proteins for function enrichment analyses and protein-protein interaction network construction. Hub protein was validated with ELISA using an independent cohort consisting of 20 samples from each group and its receiver operating characteristic (ROC) curve analysis was conducted. A total of 583 proteins were identified and 101 proteins were found to be differentially expressed, including 63 up-regulated proteins and 38 down-regulated proteins. The bioinformatics analysis suggested that PM is closely associated with immunity and inflammation interactions, and remodeling of extracellular matrix. Apolipoprotein A-I (ApoA1) was enriched as the hub protein of the network with the highest score, degree and centrality. ROC analysis showed that ApoA1 could distinguish PM from controls with an area under the curve of 0.963 (p < 0.001). The findings could provide potential clues for further study on the molecular mechanisms and developing new treatments for PM, especially related to immunity and inflammation interactions. ApoA1 may be a potential key protein and therapeutic target in human PM. SIGNIFICANCE: It is important and urgent to discover the mechanisms of pathologic myopia (PM) to inhibit its progression. This study applied the quantitative proteomic analysis to study aqueous humor from patients with or without PM, aiming to discover dysregulated proteins related to PM. Our results suggested that those dysregulated proteins are closely associated with immunity and inflammation interactions, and remodeling of extracellular matrix. The findings from this study could provide potential clues for further research on the molecular mechanisms and developing new treatments for PM, especially related to immunity and inflammation. ApoA1 may be a potential key protein and therapeutic target in human PM.

Abstract
Purpose: Recent investigations described a host of disadvantageous myopia comorbidities including decreased QOL, depression, and sleep problems. The present study evaluated mental status and habitual sleep in young subjects with myopia based on the reported association between myopic error and psychiatric profiles. Methods: This cross-sectional study surveyed 153 university students using a questionnaire containing the Pittsburgh Sleep Quality Index (PSQI), Subjective Happiness Scale (SHS), short morningness/eveningness questionnaire, and Hospital Anxiety and Depression Scale (HADS). Results: Participants were classified as having high myopia (n = 44), mild myopia (n = 86), or no myopia (n = 23). The SHS and HADS scores in this cohort were significantly worse in the high myopia group than in the other two groups (p < 0.05, t-test). PSQI values were not significantly different among the three groups. Regression analysis correlated myopic error with poor SHS (p = 0.003), eveningness chronotype (p = 0.032), late wake-up time (p = 0.024), and late bedtime (p = 0.019). Conclusions: University students with myopia tended to be unhappy, have an eveningness chronotype, wake up late, and go to bed late compared to less myopic subjects. Optimal correction might, therefore, be beneficial to myopic students in addition to preventing progression to high myopia in early childhood to potentially avoid related negative effects on mental health and sleep habits in adolescence.

Abstract
PURPOSE To investigate associated factors with optic disc characteristics in high myopia patients. METHODS According to the meta-analysis of pathologic myopia study, patients were divided into groups from categories 1 (C1) to C4. The diameters, tilt ratio, and rotation degree of optic disc, and the diameters of parapapillary atrophy were measured among other morphometric variables. RESULTS Totally 147 eyes (84 patients) were included. Longer horizontal optic disc diameter was associated with smaller tilt ratio (p < 0.001, unstandardized regression coefficient B: -0.59), greater rotation degree (p < 0.001, B: 0.01), and longer horizontal delta zone diameter (p < 0.001, B: 0.09). Longer vertical optic disc diameter was associated with smaller rotation degree (p < 0.001, B: 0.01), longer vertical delta zone diameter (p < 0.001, B: 0.16), and longer disc-fovea distance (DFD; p < 0.024, B: 0.14). Generally, the horizontal optic disc diameter of C3 and C4 groups was smaller than C1 and C2, while vertical diameter and tilt ratio was greater than in C1 and C2. After setting axial length (AL) as an independent variable, horizontal diameters and tilt ratio still showed significant differences, while vertical diameters did not show significant differences. CONCLUSION Axial elongation was associated with an increase of vertical optic disc diameter that was correlated with an reduction of optic disc rotation degree. By contrast, horizontal optic disc diameter elongation was correlated with an reduction of optic disc tilt ratio and an increase of optic disc rotation degree, which was independent of axial elongation.

Abstract
PURPOSE To analyze the hallmark features of pathologic myopia developed in animal models and compare them with those seen in patients. METHODS A literature review was performed to identify animal models that exhibited key features of pathologic myopia, namely posterior staphyloma, myopic maculopathy, lacquer cracks, and choroidal neovascularization, either spontaneously or induced by monocular deprivation. Using imaging modalities, such as optical coherence tomography, confocal scanning laser ophthalmoscopy, fluorescein angiography, and electron microscopy, these features were compared with those found in myopic maculopathy of patients. RESULTS Three types of animals were identified. The LRP2 knockout mice exhibited posterior staphylomas and chorioretinal atrophy at 21 and 60 days after birth, respectively. Retinopathy globe enlarged (rge) chicks and normal lid-sutured chicks developed lacquer cracks and chorioretinal atrophy. Lacquer cracks detected in rge chicks subsequently progressed to patchy chorioretinal atrophy, which is also commonly seen in patients with pathologic myopia. CONCLUSION The LRP2 knockout mice, retinopathy globe enlarged (rge) chicks, and normal lid-sutured chicks exhibit features typical for myopic maculopathy in patients and could serve to further elucidate the pathogenesis of myopic maculopathy.

Abstract
Background This study aimed to investigate differentially expressed proteins in the vitreous humor (VH) of pathological myopia (PM) and normal eyes. Methods VH samples were collected from patients undergoing surgical treatment for rhegmatogenous retinal detachment (RRD), idiopathic epiretinal membrane (ERM), myopic retinoschisis (MRS) or macular hole (MH). A label-free quantitative proteomic analysis was performed to detect the differentially expressed proteins, and expression of three differentially expressed proteins was confirmed by ELISA. Results In PM patients (MH-PM, MRS-PM and RRD-PM), the expression of prostaglandin-H2 D-isomerase (PGDS) and glutathione peroxidase 3 (GPX3) was significantly lower than in controls (MH, ERM, and RRD). The versican core protein expression decreased in the PM group. The vitreous concentrations of PGDS and GPX3 in patients with axial length (AL) of 26.5–29.0 mm were higher than in patients with AL >29.0 mm or AL <26.5 mm. NRF-2 expression was the lowest in patients with AL >29.0 mm. Conclusions Our study provides new evidence on the molecular changes in the VH of PM patients, and these molecules have the potential to become new targets for the therapy of PM.

[PMID: 31961888 PMCID: PMC6974143 DOI: 10.1371/journal.pone.0227557] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Accepted: 12/20/2019] [Indexed: 11/19/2022] Open
Abstract
Purpose To assess the 1-year effectiveness, safety, and treatment patterns of ranibizumab in patients with myopic choroidal neovascularization (mCNV) enrolled in the LUMINOUS study. Methods This 5-year, prospective, multicenter, observational, study enrolled 30,138 patients across all approved ranibizumab indications from outpatient ophthalmology clinics. 297 consenting patients (≥18 years) with mCNV who were treatment-naïve or prior-treated with ranibizumab or other ocular treatments were enrolled, and treated with ranibizumab according to the local product label. The main outcomes are visual acuity (VA; Early Treatment Diabetic Retinopathy Study letters or equivalent), adverse events during the study, and treatment exposure over 1 year. Results are presented by prior treatment status of the study eye and injection frequency. Results Of the 297 mCNV patients recruited in the study, 108 were treatment-naïve and 175 were prior ranibizumab-treated. At baseline, the mean age of patients was 57.6 years, and 59.0 years and 80.6% and 65.7% were female in the treatment-naïve and prior ranibizumab-treated groups, respectively. Most were Caucasian (treatment-naïve, 88.9%; prior ranibizumab-treated, 86.9%). The mean (±standard deviation [SD]) VA letter changes to 1 year were +9.7 (±17.99) from 49.5 (±20.51) and +1.5 (±13.15) from 58.5 (±19.79) and these were achieved with a mean (SD) of 3.0 (±1.58) and 2.6 (±2.33) injections in the treatment-naïve and prior ranibizumab-treated groups, respectively. Presented by injection frequencies 1–2, 3–4 and ≥5 injections in Year 1, the mean (SD) VA changes were +15.0 (±14.70), +7.7 (±19.91) and −0.7 (±16.05) in treatment-naïve patients and +1.5 (±14.57), +3.1 (±11.53) and −3.6 (±11.97) in prior ranibizumab-treated patients, respectively. The safety profile was comparable with previous ranibizumab studies. Conclusions Ranibizumab treatment for mCNV showed robust VA gains in treatment-naïve patients and VA maintenance in prior ranibizumab-treated patients in a clinical practice setting, consisting mainly of Caucasians. No new safety signals were observed during the study.

Morphological Characteristics and Risk Factors of Myopic Maculopathy in an Older High Myopia Population-Based on the New Classification System (ATN). Am J Ophthalmol 2019; 208:356-366. [PMID: 31351050 DOI: 10.1016/j.ajo.2019.07.010] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2019] [Revised: 07/16/2019] [Accepted: 07/16/2019] [Indexed: 02/08/2023]
Abstract
PURPOSE To investigate the characteristics, mergers, and risk factors of different types of myopic maculopathy (MM) in a highly myopic population. DESIGN Population-based, cross-sectional study. METHODS A total of 1086 eyes (762 patients) were enrolled. Each participant underwent detailed ocular examinations. Combining the fundus photographs and optical coherence tomography images, types of MM were assessed as myopic atrophy maculopathy (MAM), myopic tractional maculopathy (MTM), or myopic neovascular maculopathy (MNM) according to the ATN classification system. Peripapillary atrophy (PPA) area, tilt ratio, and macular choroidal thickness (mChT) were measured individually. RESULTS Eyes with larger PPA area were more likely to have MAM (odds ratio [OR], 1.220; P = .037 per 1-mm2 increase) and MNM (OR, 1.723; P < .001 per 1-mm2 increase), and eyes with thicker mChT were less likely to have MAM (OR, 0.740; P < .001 per 10-μm increase) and MNM (OR, 0.784; P < .001 per 10-μm increase), whereas eyes with higher tilt ratio were less likely to have MTM (OR, 0.020; P < .001 per 1 increase). The severity of MTM and MNM was not precisely consistent with that of MAM. CONCLUSIONS Different types of MM have different risk factors; larger PPA area and thinner mChT are risk factors for MAM and MNM, whereas lower tilt ratio is a risk factor for MTM. Our results indicate that the pathogenesis of MTM is different from that of MAM and MNM, and a tractional component should be considered as a possible component to the myopic macular classification.

Abstract
Myopia is a highly frequent ocular disorder worldwide and pathologic myopia is the 4th most common cause of irreversible blindness in developed countries. Pathologic myopia is especially common in East Asian countries. Ocular alterations associated with pathologic myopia, especially those involving the macular area-defined as myopic maculopathy-are the leading causes of vision loss in patients with pathologic myopia. High myopia is defined as the presence of a highly negative refractive error (>-6 to -8 diopters) in the context of eye elongation (26-26.5 mm). Although the terms high myopia and pathologic myopia are often used interchangeably, they do not refer to the same eye disease. The two key factors driving the development of pathologic myopia are: 1) elongation of the axial length and 2) posterior staphyloma. The presence of posterior staphyloma, which is the most common finding in patients with pathologic myopia, is the key differentiating factor between high and pathologic myopia. The occurrence of staphyloma will, in most cases, eventually lead to other conditions such as atrophic, traction, or neovascular maculopathy. Posterior staphyloma is for instance, responsible for the differences between a myopic macular hole (MH)-with and without retinal detachment-and idiopathic MH. Posterior staphyloma typically induces retinal layer splitting, leading to foveoschisis in myopic MH, an important differentiating factor between myopic and emmetropic MH. Myopic maculopathy is a highly complex disease and current classification systems do not fully account for the numerous changes that occur in the macula of these patients. Therefore, a more comprehensive classification system is needed, for several important reasons. First, to more precisely define the disease stage to improve follow-up by enabling clinicians to more accurately monitor changes over time, which is essential given the progressive nature of this condition. Second, unification of the currently-available classification systems would establish standardized classification criteria that could be used to compare the findings from international multicentric studies. Finally, a more comprehensive classification system could help to improve our understanding of the genetic origins of this disease, which is clearly relevant given the interchangeable-but erroneous-use of the terms high and pathologic myopia in genetic research.

Abstract
Background Macular neovascular diseases can cause severe vision loss. A newly approved anti—VEGF drug Conbercept has shown good efficacy and safety in rigorous random controlled trials (RCT), however, it cannot fully reflect the clinical application of Conbercept in real world clinical practice. Moreover, anti-VEGF drugs are expensive and often require multiple treatments, and some patients have poor or even no response to the drugs,this resulted enormous waste of medical resources. Therefore, how to find out those patients who have good response, and how to develop individualized therapeutic regimen in real world need to be urgently investigated in the aspect of pharmacogenomics and pharmacometabolomics. Methods This study is a multicenter, prospective, observational study of Conbecept treating macular neovascular diseases in China. Patients suffered from age-related macular degeneration, polypoidal choroidal vasculopathy, and pathological myopia who already planned to receive Conbercept treatment will be recruited. We aimed to enroll more than 5000 patients from 43 ophthalmic centers in China. Patients’ clinical data and blood samples will be collected during the one-year follow-up period. Finally, the safety and efficacy of Conbercept, and the potential predictors of patients’ response to Conbercept will be investigated by pharmacogenomics and pharmacometabolomics analysis. Discussion This study will provide important data of Conbercept in treating macular neovascular diseases in real world. Besides, finding the predictor of patients’ response will help doctor make more precise individualized therapeutic regimens. Trial registration ClinicalTrials.gov, NCT03128463.

Abstract
PURPOSE To assess the natural disease progression of high myopia in Caucasians considered at risk for the development of myopic choroidal neovascularization (mCNV). METHODS Subjects were recruited in 25 clinical sites between June 2014 and June 2016. Main inclusion criteria included axial length of ≥26 mm, best-corrected visual acuity ≥0.05 decimal equivalent and presence of at least one out of five predefined morphological disease risk criteria. These were (1) subfoveal choroidal thinning < 50 µm, (2) enhanced choroidal curvature length > 6,300 µm, (3) lacquer cracks, (4) patchy atrophy > 5 mm2 and (5) preexisting mCNV in the fellow eye (German Clinical Trial Register DRKS00007761). RESULTS A total of 150 participants (66% females) with a mean age of 57.2 (±12.7) years (range 21.9-86.2 years) were included. The disease criteria most frequently encountered were choroidal thinning (33.3%) and lacquer cracks (32.7%). Enhanced choroidal curvature length was detected in only 8 subjects and always occurred in combination with other disease criteria. Presence of patchy atrophy was found to be more common in older subjects (p = 0.0012) and also associated with a more severe disease manifestation. CONCLUSION The baseline data of this study indicate that enhanced choroidal curvature might be less common in Caucasians than in Asian populations. Further, disease severity in patients with high myopia is relatively high in the presence of patchy atrophy.

Abstract
This retrospective consecutive case series aimed to evaluate spectral-domain optical coherence tomography (SD-OCT) for occult macular disease recognition preoperatively in patients scheduled for routine cataract surgery. All patients scheduled for cataract surgery underwent macular SD-OCT. Scans were reviewed for retinal, retinal pigment epithelium and vitreomacular interface abnormalities. For the subgroup analysis, the following information was collected: age; sex; and diabetes, hypertension, myopia, glaucoma, post intra-ocular surgery, endophotocoagulation, retinal vasculopathy and uveitis statuses. One-thousand-one-hundred-seventy-six consecutive scans were acquired from 1,176 patients. Macular pathology was found in 294 eyes. The most common macular disorders were an epiretinal membrane (n = 130), myopia atrophy (n = 61) and a dome-shaped macular with pathologic myopia (n = 32). One-hundred-thirty eyes (11.05%) presented macular epiretinal membranes not detected by dilated fundus examination, accounting for 44.22% of the abnormalities in diseased eyes and was higher than in previous Chinese studies. Some had multiple macular disorders. The most common ocular history was myopia, including high myopia. The pooled prevalence rate of macular diseases detected by OCT was 0.24 (95% CI 0.14-0.34) using meta-analysis. SD-OCT should be performed for routine cataract surgery patients to evaluate visual outcomes, especially in myopic patients and those considering advanced-technology intraocular lenses.

Abstract
Objective This study aimed to investigate the efficacy of minimally invasive repetitive UVA irradiation along with riboflavin treatment on sclera collagen cross-linking in rabbits. Method Forty-eight healthy adult New Zealand white rabbits were randomly divided into four groups: pseudosurgery group (group I), single-irradiation group (group II), duplicate-irradiation group (group III), and triplicate-irradiation group (group IV), with 12 rabbits in each group. For the single-irradiation group, a specially made LED light source was inserted through a minimally invasive conjunctival incision to gain close contact with the sclera for irradiation, and for the repetitive irradiation groups, the above experimental procedure was repeated once or twice every other week. Biomechanical parameters of the sclera including ultimate stress (σ) and 8% Young's modulus (E) were compared among the groups. Results In comparison with control group I, the ultimate stress of group II, group III, and group IV increased by 80.1%, 107.9%, and 182.1%, respectively, and their 8% Young's modulus increased by 106.1%, 159.5%, and 208.5%, respectively, one day after surgery (P < 0.01). Conclusion Repetitive minimally invasive UVA irradiation with riboflavin significantly increased biomechanical strength of the sclera in the irradiated area, and biomechanical strength increased with repeated times of irradiation.

Abstract
Pathologic myopia is a leading cause of visual impairment. Development of myopic choroidal neovascularization (CNV) is one of the most common complications that leads to central vision loss in patients with pathologic myopia. If left untreated, it can cause scarring with expanding macular atrophy leading to irreversible visual loss in a period as short as 5 years. Advancements in multimodal imaging technology have furthered our understanding of the condition; however, further studies are necessary to extend its utility in the diagnosis of myopic CNV. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy has become the standard-of-care and the recommended first-line treatment option for myopic CNV. Long-term studies have demonstrated that early treatment of confirmed myopic CNV cases with an intravitreal anti-VEGF agent is useful to avoid late-stage complications. This strategy has also been shown to achieve visual outcome improvements for up to 4 years and visual stabilization up to 6 years. This review article provides an overview of the current knowledge on myopic CNV and discusses recent updates in the diagnosis and management of the condition. Furthermore, treatment recommendations are provided based on the authors' expert opinions.

Abstract
PURPOSE The aim of this study was to explore the role of age as a prognostic factor for the outcome of myopic choroidal neovascularization (CNV) treatment with intravitreal ranibizumab injections. METHODS A retrospective review of charts of patients treated with intravitreal injections of ranibizumab for the treatment of myopic CNV was done. Patients with other ophthalmic disease were excluded. Patients were followed for at least 2 years. The correlation between age and the change in visual acuity and the number of injections during treatment was investigated. RESULTS Age of the patients was significantly correlated with the number of injections that the patients received (Pearson's r=0.585, P=0.005). Also, it was significantly correlated with improvement in corrected distance visual acuity, defined as the difference between final and initial LogMAR corrected distance visual acuity (Pearson's r=0.614, P=0.003). CONCLUSION Age significantly affects the visual outcome of myopic CNV treatment with ranibizumab. Younger patients in our study needed fewer intravitreal injections and achieved a more significant improvement in vision.

Abstract
Choroidal neovascularization (CNV) commonly occurs in age related macular degeneration and pathological myopia patients. In this study we conducted a case-control prospective study including 431 participants. The aim of this study was to determine the potential association between 10 single nucleotide polymorphisms (SNPs) located in 4 different genetic regions (CFI, COL8A1, LIPC, and APOE), and choroidal neovascularization in age-related macular degeneration and the development of choroidal neovascularization in highly myopic eyes of a Caucasian population. Univariate and multivariate logistic regression analysis adjusted for age, sex and hypertension was performed for each allele, genotype and haplotype frequency analysis. We found that in the univariate analysis that both single-nucleotide polymorphisms in COL8A1 gene (rs13095226 and rs669676) together with age, sex and hypertension were significantly associated with myopic CNV development in Spanish patients (p<0.05). After correcting for multiple testing none of the polymorphisms studied remained significantly associated with myopic CNV (p>0.05); however, analysis of the axial length between genotypes of rs13095226 revealed an important influence of COL8A1 in the development of CNV in high myopia. Furthermore we conducted a meta-analysis of COL8A1, CFI and LIPC genes SNPs (rs669676, rs10033900 and rs10468017) and found that only rs669676 of these SNPs were associated with high myopia neovascularization.

Abstract
MicroRNAs (miRNAs) modulate complex physiological and pathological processes, including the regulation of angiogenesis. Our previous study reported that bone marrow-derived mesenchymal stem cells (MSCs) are recruited into choroidal neovascularization lesions. miRNA-195 is highly expressed in MSCs, but its function remains unknown. In the present study, miR-195a-3p abundance was significantly decreased in hypoxia-treated murine MSCs; on the other hand, its overexpression reduced MSC proliferation and migration while increasing the activation of anti-angiogenic factor pigment epithelium-derived factor (PEDF). We further discovered that matrix metalloproteinase 2 (Mmp2) transcript is a target of miR-195a-3p, and that silencing Mmp2 phenocopied the reduced proliferation and migration of MSCs. The therapeutic potential of miR-195a-3p as an angiogenesis inhibitor was also demonstrated in a laser-induced choroidal neovascularization mouse model. These findings collectively indicate that miR-195a-3p is a negative modulator of angiogenesis, and could be used as an angiogenesis inhibitor. Mol. Reprod.
