RESUMEN
Myopia most often develops during school age, with the highest incidence in countries with intensive education systems. Interactions between genetic variants and educational exposure are hypothesized to confer susceptibility to myopia, but few such interactions have been identified. Here, we aimed to identify genetic variants that interact with education level to confer susceptibility to myopia. Two groups of unrelated participants of European ancestry from UK Biobank were studied. A 'Stage-I' sample of 88,334 participants whose refractive error (avMSE) was measured by autorefraction and a 'Stage-II' sample of 252,838 participants who self-reported their age-of-onset of spectacle wear (AOSW) but who did not undergo autorefraction. Genetic variants were prioritized via a 2-step screening process in the Stage-I sample: Step 1 was a genome-wide association study for avMSE; Step 2 was a variance heterogeneity analysis for avMSE. Genotype-by-education interaction tests were performed in the Stage-II sample, with University education coded as a binary exposure. On average, participants were 58 years-old and left full-time education when they were 18 years-old; 35% reported University level education. The 2-step screening strategy in the Stage-I sample prioritized 25 genetic variants (GWAS P < 1e-04; variance heterogeneity P < 5e-05). In the Stage-II sample, 19 of the 25 (76%) genetic variants demonstrated evidence of variance heterogeneity, suggesting the majority were true positives. Five genetic variants located near GJD2, RBFOX1, LAMA2, KCNQ5 and LRRC4C had evidence of a genotype-by-education interaction in the Stage-II sample (P < 0.002) and consistent evidence of a genotype-by-education interaction in the Stage-I sample. For all 5 variants, University-level education was associated with an increased effect of the risk allele. In this cohort, additional years of education were associated with an enhanced effect of genetic variants that have roles including axon guidance and the development of neuronal synapses and neural circuits.

PURPOSE: To determine the prevalence and characteristics of radial fundus autofluorescence (FAF) in highly myopic women. METHODS: This was a retrospective, observational case study to determine the prevalence of radial FAF in the ultra-widefield FAF images in women. The clinical characteristics of these patients were evaluated. RESULTS: Fifteen of 1,935 (0.78%) highly myopic women were found to have radial FAF. Their mean age was 36.6 ± 25.6 years, and their mean best-corrected visual acuity was 0.3 ± 0.42 logMAR units. The mean axial length (AL) was 28.8 ± 2.8 mm. Among the 15 cases, eight did not have pigmentary changes and seven had pigmentary changes in the ultra-widefield FAF images. The women with the pigmentary changes were significantly older ( P = 0.021), had poorer BCVA ( P = 0.001), and had longer ALs ( P = 0.002). The visual fields and electroretinograms were worse in the eyes with pigmentary changes. CONCLUSION: The prevalence of radial FAF was 0.78% in women with high myopia. These patients might have mutations in the RPGR or RP2 genes and can develop high myopia and retinitis pigmentosa. Ultra-widefield FAF images should be examined in all highly myopic patients for early detection of radial FAF, and myopia prevention and genetic counseling for possible genetic therapy are recommended.

PURPOSE: To assess the longitudinal changes of the posterior vortex veins (VVs) in highly myopic (HM) eyes. METHODS: The medical records of 1,730 consecutive HM eyes that had undergone indocyanine green angiography were studied. Eyes that had posterior VVs and had undergone at least two indocyanine green angiography examinations with a minimum interval of 3 years were selected from this group. RESULTS: Ninety-one eyes of 78 patients met the inclusion criteria. A total of 124 posterior VVs were identified. Over an average interval of 7.8 ± 5.0 years, 41 (33.1%) of the 124 posterior VVs had marked changes consisting mainly of an attenuation of vessels in 36 posterior VVs (87.8%) and alterations in the drainage course in 16 posterior VVs (39.0%). Fifteen posterior VVs had both types of changes. Most of the attenuations of the vessels occurred for smaller branches, but a complete loss of the entire trunk was seen in three eyes. Additionally, four eyes had posterior VV changes in association with changes of peripheral VVs. CONCLUSION: Posterior VV in highly myopic eyes can undergo changes with increasing time. The associated factors included the development and progression of myopic maculopathy lesions. In some cases, the blood drainage shifted from posterior VV to peripheral VV by forming anastomotic channels.

Vaccination is a public health cornerstone that protects against numerous infectious diseases. Despite its benefits, immunization implications on ocular health warrant thorough investigation, particularly in the context of vaccine-induced ocular inflammation. This review aimed to elucidate the complex interplay between vaccination and the eye, focusing on the molecular and immunological pathways implicated in vaccine-associated ocular adverse effects. Through an in-depth analysis of recent advancements and the existing literature, we explored various mechanisms of vaccine-induced ocular inflammation, such as direct infection by live attenuated vaccines, immune complex formation, adjuvant-induced autoimmunity, molecular mimicry, hypersensitivity reactions, PEG-induced allergic reactions, Type 1 IFN activation, free extracellular RNA, and specific components. We further examined the specific ocular conditions associated with vaccination, such as uveitis, optic neuritis, and retinitis, and discussed the potential impact of novel vaccines, including those against SARS-CoV-2. This review sheds light on the intricate relationships between vaccination, the immune system, and ocular tissues, offering insights into informed discussions and future research directions aimed at optimizing vaccine safety and ophthalmological care. Our analysis underscores the importance of vigilance and further research to understand and mitigate the ocular side effects of vaccines, thereby ensuring the continued success of vaccination programs, while preserving ocular health.

Human T-cell leukemia virus type 1 (HTLV-1), a virus that affects 5-10 million people globally, causes several diseases, including adult T-cell leukemia-lymphoma and HTLV-1-associated uveitis (HU). HU is prevalent in Japan and often leads to secondary glaucoma, which is a serious complication. We investigated the efficacy of ripasudil, a Rho-associated coiled coil-forming protein kinase inhibitor, in alleviating changes in human trabecular meshwork cells (hTM cells) infected with HTLV-1. HTLV-1-infected hTM cells were modeled in vitro using MT-2 cells, followed by treatment with varying concentrations of ripasudil. We assessed changes in cell morphology, viability, and inflammatory cytokine levels, as well as NF-κB activation. The results showed that ripasudil treatment changed the cell morphology, reduced the distribution of F-actin and fibronectin, and decreased the levels of certain inflammatory cytokines, such as interleukin (IL)-6, IL-8, and IL-12. However, ripasudil did not significantly affect NF-κB activation or overall cell viability. These findings suggest that ripasudil has the potential to treat secondary glaucoma in patients with HU by modulating cytoskeletal organization and alleviating inflammation in HTLV-1-infected hTM cells. This study lays the foundation for further clinical studies exploring the effectiveness of ripasudil for the treatment of secondary glaucoma associated with HU.

PURPOSE: To develop and validate the performance of a high myopia (HM)-specific normative database of peripapillary retinal nerve fiber layer (pRNFL) thickness in differentiating HM from highly myopic glaucoma (HMG). DESIGN: Cross-sectional multicenter study. PARTICIPANTS: A total of 1367 Chinese participants (2325 eyes) with nonpathologic HM or HMG were included from 4 centers. After quality control, 1108 eyes from 694 participants with HM were included in the normative database; 459 eyes from 408 participants (323 eyes with HM and 136 eyes with HMG) and 322 eyes from 197 participants (131 eyes with HM and 191 eyes with HMG) were included in the internal and external validation sets, respectively. Only HMG eyes with an intraocular pressure > 21 mmHg were included. METHODS: The pRNFL thickness was measured with swept-source (SS) OCT. Four strategies of pRNFL-specified values were examined, including global and quadrantic pRNFL thickness below the lowest fifth or the lowest first percentile of the normative database. MAIN OUTCOMES MEASURES: The accuracy, sensitivity, and specificity of the HM-specific normative database for detecting HMG. RESULTS: Setting the fifth percentile of the global pRNFL thickness as the threshold, using the HM-specific normative database, we achieved an accuracy of 0.93 (95% confidence interval [CI], 0.90-0.95) and 0.85 (95% CI, 0.81-0.89), and, using the first percentile as the threshold, we acheived an accuracy of 0.85 (95% CI, 0.81-0.88) and 0.70 (95% CI, 0.65-0.75) in detecting HMG in the internal and external validation sets, respectively. The fifth percentile of the global pRNFL thickness achieved high sensitivities of 0.75 (95% CI, 0.67-0.82) and 0.75 (95% CI, 0.68-0.81) and specificities of 1.00 (95% CI, 0.99-1.00) and 1.00 (95% CI, 0.97-1.00) in the internal and external validation datasets, respectively. Compared with the built-in database of the OCT device, the HM-specific normative database showed a higher sensitivity and specificity than the corresponding pRNFL thickness below the fifth or first percentile (P < 0.001 for all). CONCLUSIONS: The HM-specific normative database is more capable of detecting HMG eyes than the SS OCT built-in database, which may be an effective tool for differential diagnosis between HMG and HM.

PURPOSE: To determine the longitudinal changes in the morphologic features of dome-shaped macula in highly myopic eyes. METHODS: Patients with a dome-shaped macula and high myopia (spherical equivalent <-8 diopters [D] or axial length ≥26.5 mm) were retrospectively studied. The medical records, optical coherence tomographic images, and ultra-widefield optical coherence tomography images were analyzed. RESULTS: A total of 113 eyes of 82 patients were studied with a mean follow-up of 122.32 ± 6.36 months. During the follow-up, the mean dome height was significantly increased from 181.51 ± 105.55 to 209.85 ± 130.84 µ m ( P < 0.001). There was also a significant increase in the axial length (30.83 ± 1.82-31.16 ± 1.86 mm; P < 0.001). Subgroup analyses showed that the dome height increased more than 50 µ m in 78 (69%) eyes, decreased in 23 (20%) eyes, and was stable in 12 (11%) eyes. The change in the axial lengths was significantly greater in the increased dome height group than in the decreased and stable dome height groups ( P = 0.042). Multivariable analysis showed that the greater axial length change (OR, 8.73; P = 0.017) and horizontal type dome-shaped macula (OR, 4.14; P = 0.026) were significantly associated with an increase in dome height. CONCLUSION: The direction of change in the dome-shaped macula height varies and 69% of the eyes had an increase in height, whereas 20% of the eyes had a decrease in height. The variations in the dome height may result from the difference between the deepening of the peridome scleral excavation and the changes of the axial length.

PURPOSE: To analyze the complex pattern of filling of the intervortex vein (IVV) anastomoses through large trunks in highly myopic eyes based on indocyanine green angiographic (ICGA) videos. METHODS: The medical records of 1,060 consecutive highly myopic eyes that had undergone ICGA were studied. IVV anastomoses were identified in the ICGA images, and the ICGA images and videos were analyzed comprehensively to characterize their hemodynamic features. RESULTS: Seven eyes with IVV anastomoses through large trunks were analyzed. In the ICGA videos of six eyes, laminar flow was observed in the IVV anastomotic vessels. The laminar flow started in the arterial phase in two eyes, with pulsatile fashion in 1 of them. The flow began in the early arteriovenous transition phase in four eyes. The laminar flow continued for a mean of 12.17 ± 3.06 seconds, and the remaining section was gradually filled slower than the surrounding veins. The anastomotic trunk for the remaining one eye was too narrow to be analyzed. Four eyes had longitudinal ICGA records, and two had significant attenuation and narrowing of the anastomotic vessels. CONCLUSION: The very early filling of part of the IVV anastomoses suggests that arteriovenous anastomoses are involved in the IVV of highly myopic eyes. However, this suggestion needs further study. There may be similar pathogenesis for IVV anastomoses either in thick or thin sclera.

PURPOSE: To investigate the development and progression patterns of macular neovascularization (MNV)-related atrophies in eyes with pathologic myopia. METHODS: Twenty-seven eyes of 26 patients with MNV followed from its onset to progression to macular atrophy were studied. A longitudinal series of autofluorescence and optical coherence tomography images were examined for the patterns of MNV-related atrophy. Changes in best-corrected visual acuity were determined for each pattern. RESULTS: The mean age was 67.2 ± 8.7 years. The mean axial length was 29.6 ± 1.5 mm. Three patterns of atrophy were identified: multiple-atrophic pattern, 63% of the eyes had small atrophies occurring at multiple sites around the MNV edge; single-atrophic pattern, 18.5% had atrophies occurring only on one side of the MNV edge; and exudation-related pattern, 18.5% had atrophy occurring within a previous serous exudation or hemorrhagic area and slightly away from the MNV edge. Eyes with atrophies in multiple-atrophic and exudation-related patterns progressed to large macular atrophies involving the central fovea and showed decrease in best-corrected visual acuity during the 3-year follow-up period. Eyes with single-atrophic pattern had a sparing of the fovea and had good recovery of the best-corrected visual acuity. CONCLUSION: There are three patterns of MNV-related atrophy in eyes with pathologic myopia with different courses of progression.

PURPOSE: To determine the longitudinal changes in patterns of inner scleral curvature and development of posterior staphylomas in the eyes of highly myopic youths. METHODS: A retrospective, longitudinal study. Ultra-widefield optic coherence tomographic (UWF-OCT) images from 47 eyes of 24 highly myopic patients with a follow-up period of 2 to 4 years were analyzed. Patients were divided into two groups, the children group younger than 10 years and the adolescents group aged 11 to 19 years. RESULTS: During the follow-up period, the scleral curvature patterns changed in either the horizontal or vertical optical coherence tomographic sections in 27 of the 46 eyes (58.7%) of both groups. The changes were significantly more frequent in children than adolescents. The change in the vertical section from symmetrical to asymmetrical in almost of children was correlated with an increase in the axial length and myopia. Four eyes had a staphyloma at the baseline. The staphyloma developed in six eyes of the remaining 43 eyes (14%). All staphyloma edges were found at or around the optic disc and were oriented in the horizontal direction. CONCLUSION: Our results showed that UWF-OCT images can be used to determine the process of new staphyloma formation and concurrent changes in scleral curvature patterns.

BACKGROUND: We retrospectively evaluate the long-term efficacy and safety of trabeculotomy glaucoma surgery in treating open-angle glaucoma (OAG) in eyes with high myopia (HM). METHODS: This study included 20 eyes with HM (axial length ≥ 26.5 mm) and OAG; age, preoperative IOP (intraocular pressure), and sex-matched 20 non-HM eyes (axial length < 26.5 mm) served as controls. Each eye underwent standalone ab interno trabeculotomy using a Kahook dual blade. A follow-up examination was performed 36 months after surgery. The main outcome measure was the operative success rate (i.e., a ≥ 20% pre- to post-operative reduction in IOP with or without IOP-lowering medication). Kaplan-Meier analysis was employed as a measure of surgical success. The secondary outcome measures were postoperative IOP, the number of glaucoma medications, and postoperative complications. RESULTS: IOP and the number of glaucoma medications were statistically significantly reduced at all postoperative follow-up examinations. The Kaplan-Meier analysis demonstrated that the probability of postoperative success at 36 months was 45% and 65% for HM and non-HM eyes, respectively. In the HM group, the presence of pathological myopia was statistically significant risk factor for surgical failure. No critical postoperative complications were detected. CONCLUSIONS: In our study, the long-term efficacy of ab interno trabeculotomy in HM eyes with OAG was inferior to that in non-HM eyes with OAG. Our findings suggest that surgical indications for trabeculotomy in HM should be determined based on the presence of pathological myopia.

PURPOSE: To develop a classification system of visual field (VF) abnormalities in highly myopic eyes with and without glaucoma. DESIGN: Secondary analysis of VF data from a longitudinal cohort study. PARTICIPANTS: One thousand eight hundred ninety-three VF tests from 1302 eyes (825 individuals). METHODS: All participants underwent VF testing (Humphrey 24-2 Swedish interactive threshold algorithm standard program; Carl Zeiss Meditec) and detailed ophthalmic examination. A comprehensive set of VF defect patterns was defined via observation of the 1893 VF reports, literature review, and consensus meetings. The classification system comprised 4 major types of VF patterns, including normal type, glaucoma-like defects (paracentral defect, nasal step, partial arcuate defect, arcuate defect), high myopia-related defects (enlarged blind spot, vertical step, partial peripheral rim, nonspecific defect), and combined defects (nasal step with enlarged blind spot). A subset (n = 1000) of the VFs was used to evaluate the interobserver and intraobserver agreement and weighted κ values of the classification system by 2 trained readers. The prevalence of various VF patterns and their associated factors were determined. MAIN OUTCOME MEASURES: The classification of VF in highly myopic eyes and its associated risk factors. RESULTS: We found that normal type, glaucoma-like defects, high myopia-related defects, and combined defects accounted for 74.1%, 10.8%, 15.0%, and 0.1% of all unique VF tests, respectively. The interobserver and intraobserver agreements were > 89%, and the corresponding κ values were 0.86 or more between readers. Both glaucoma-like and high myopia-related VF defects were associated with older age (odds ratios [ORs], 1.07 [95% confidence interval (CI), 1.04-1.10; P < 0.001] and 1.06 [95% CI, 1.04-1.10; P < 0.001]) and longer axial length (ORs, 1.65 [95% CI, 1.32-2.07; P < 0.001] and 1.37 [95% CI, 1.11-1.68; P = 0.003]). Longer axial length showed a stronger effect on the prevalence of glaucoma-like VF defects than on the prevalence of high myopia-related VF defects (P = 0.036). CONCLUSIONS: We propose a new and reproducible classification system of VF abnormalities for nonpathologic high myopia. Applying a comprehensive classification system will facilitate communication and comparison of findings among studies.

PURPOSE: To determine the clinical and imaging characteristics, natural course, and surgical outcomes of pathologic myopic eyes with an extreme macular schisis simulating a retinal detachment (EMSSRD). METHODS: The data of 617 highly myopic eyes with myopic traction maculopathy were studied. The diagnosis of EMSSRD in the optical coherence tomography images was made based on a high elevation of the retina (>500 µ m), less obvious columnar structures, and the presence of thin remnants of outer retinal tissues above the retinal pigment epithelium. RESULTS: Among 617 eyes, 25 eyes had an EMSSRD. All of the eyes with an EMSSRD had macular atrophy caused by myopic macular neovascularization. In the five eyes they had progressed to MHRD, the retinal detachment started away from the macular atrophy. Among the 10 eyes which required surgery, there was no significant difference in the presurgical and postsurgical best-corrected visual acuity between the eyes operated because of a worsening of the EMSSRD and the eyes operated because of a progression to MHRD. CONCLUSION: In severely myopic eyes with macular neovascularization-related macular atrophy, a novel condition termed EMSSRD can be present. The optical coherence tomography images resemble those of a MHRD except the presence of thin remnants of the retina remaining on the retinal pigment epithelium.

PURPOSE: To identify anomalies of choroidal venous structure in highly myopic (HM) eyes. METHODS: Widefield indocyanine green angiographic images of 175 HM eyes (refractive error ≤ -6.0D diopters or axial length >26.5 mm) and 100 control eyes taken between January 2014 and December 2018 were reviewed. RESULTS: There were no significant differences in age and gender between HM patients and controls. Three types of changes of large choroidal veins were found in 103 HM eyes (58.86%): Asymmetry of vortex veins in 44 eyes (25.14%), isolated long vein across the macula in 58 eyes (33.14%), and intervortex anastomoses in 25 eyes (14.29%). Similar changes in controls were found in 12 eyes (12%), 0 eye (0%), and 2 eyes (2%), respectively, which were significantly lower than those in the HM group (all P < 0.05). The patterns of asymmetry were affected by steeper staphyloma edges and anastomoses were observed through large trunks and terminal venules. In two eyes with large trunk anastomosis, attenuation of the less dominant vortex vein was observed afterward. CONCLUSION: Choroidal venous anomalies are more common in HM eyes than controls. Choroidal venous structure in HM eyes may be altering continuously, and such changes may underlie the development of myopic maculopathy.

PURPOSE: To determine the prevalence and characteristics of multifocal choroiditis/punctate inner choroidopathy (MFC/PIC) in eyes with patchy atrophy because of pathologic myopia. METHODS: Five hundred eyes of 253 patients with patchy atrophy were examined between 2014 and 2020 at the Advanced Clinical Center for Myopia. The main outcome measures included the prevalence and characteristics of active MFC/PIC lesions diagnosed by optical coherence tomography. RESULTS: Fifty-five of the 500 eyes (11%) diagnosed with patchy atrophy had optical coherence tomography features of active MFC/PIC lesions, such as focal elevations of the retinal pigment epithelium filled with medium hyperreflectivity material, curvilinear scars (Schlaegel lines), and/or areas of outer retinal atrophy. At the time when the MFC/PIC was diagnosed, the mean age was 57.3 ± 12.0 years, and the mean axial length was 29.2 ± 1.8 mm. Macular neovascularization was found in 45 of eyes (81.8%) with MFC/PIC versus 151 eyes without such findings (33.9%; P < 0.001). In 25 of the 55 eyes (45.5%), active MFC/PIC lesions were found before the development of the patchy atrophy. The Bruch membrane defects were colocated with these lesions. CONCLUSION: Active MFC/PIC lesions were identified in a minority of eyes with pathologic myopia, and a subset of these lesions were observed to progress to findings indistinguishable from myopic patchy atrophy. Evidence of MFC/PIC in eyes with pathologic myopia appeared to be a risk factor for the development of macular neovascularization.

INTRODUCTION: Myopic macular neovascularization (MNV) is the most common cause of a reduction of central vision in eyes with pathologic myopia, and it can progress to macular atrophy in the long-term. The aim of this study was to determine the risk factors associated with the development of MNVs. METHODS: There were 17,198 follow-up records from 5,409 eyes of 2,784 highly myopic patients that were reviewed. The general information and ophthalmic information in the records were studied. The significance of the correlations of factors associated with the development and predicting the development of myopic MNV were determined. RESULTS: Being a woman (odds ratio [OR]: 0.727, P<0.001), having a longer axial length (OR = 0.948, P<0.001), a poorer baseline best-correct visual acuity (BCVA, OR = 2.098, P<0.001), having severe myopic maculopathy (overall: P<0.001), prior myopic MNV in the fellow eye (OR = 4.105, P<0.001), presence of patchy atrophy (overall P<0.001), lacquer cracks (OR = 1.718, P<0.001), prior foveal retinal detachment (RD, OR = 3.269, P<0.001), prior macular hole (MH, OR = 0.641, P <0.001), prior macular retinoschisis (OR = 1.533, P<0.001), and prior macular edema (OR = 1.508, P<0.001) were significantly correlated with the development of myopic MNV. Eyes with MNV and patchy atrophy would require an intensive follow-up examination for myopic patients as the fellow eye would have a risk of >70% for the development of myopic MNV in 3-years and nearly 80% in 5-years. CONCLUSIONS: Clinicians need to pay special attention to eyes with severe grades of myopic maculopathy, prior myopic MNV in the fellow eye, presence of patchy atrophy, and prior foveal retinal detachment to determine the onset of myopic MNV.
RESUMEN
PURPOSE: To examine most postequatorial retina in eyes with myopic macular retinoschisis (MRS) by ultra-widefield (UWF) OCT and to determine whether paravascular vitreal adhesions play a role in the development of MRS. DESIGN: Retrospective single-center observational case series. PARTICIPANTS: One hundred fifty highly myopic participants who were older than 50 years with and without an MRS were studied. High myopia was defined as an eye with an axial length of more than 26.5 mm. METHODS: All participants underwent UWF OCT imaging with a scan width of 23 mm and a depth of 5 mm using a prototype swept-source OCT device. The vitreoretinal adhesions to the foveal retina and retinal vessels and paravascular abnormalities, including paravascular retinal cysts, paravascular retinoschisis, and paravascular lamellar holes, were analyzed in the UWF OCT images. The findings in eyes with an MRS were compared with those in eyes without an MRS. MAIN OUTCOME MEASURES: The relationships between MRS and vitreal adhesions to the retinal vessels or to the fovea were determined. RESULTS: An MRS was found in 49 of the 150 eyes (33%). Vitreal adhesions to the retinal vessels were found more frequently in eyes with an MRS than in eyes without an MRS (63% vs. 44%; P = 0.04). In contrast, the number of eyes with adhesions to the fovea in eyes with an MRS was not significantly different from that in eyes without an MRS (57% vs. 59%). Paravascular lesions, for example, retinal cysts, retinoschisis, and lamellar holes, were more common in eyes with an MRS than in eyes without an MRS (71% vs. 36%, 61% vs. 17 %, and 20% vs. 8% [P < 0.001, P < 0.001, and P = 0.03], respectively). Multivariate analysis showed that the presence of paravascular vitreal adhesions was a significant predictor for MRS development (odds ratio, 2.56; P = 0.02). CONCLUSIONS: Paravascular vitreal adhesions may be related to the development of the different types of paravascular lesions including retinal cysts and retinoschisis, and play a more important role in the development of an MRS than vitreal adhesions to the fovea.

PURPOSE: To investigate morphologic features along posterior staphyloma edges in eyes with pathologic myopia using ultra-widefield optical coherence tomography imaging. METHODS: Highly myopic patients (refractive error < -8 diopters or axial length ≥26.5 mm) were consecutively examined by prototype ultra-widefield optical coherence tomography with a scan width of 23 mm and depth of 5 mm. Staphyloma edges were assessed for scleral, choroidal, and retinal status, as well as measurements of angle size. Findings were correlated with pigmentary changes observed on Optos fundus photography, and multivariate logistic regression analyses were performed. RESULTS: In 164 eyes diagnosed with posterior staphyloma by ultra-widefield optical coherence tomography, choroidal thinning and scleral protrusion were hallmark features of staphyloma edges, observed simultaneously in more than 95% of staphylomatous eyes. Outer neural retinal thinning was observed in 80 eyes (48.8%), whereas 15 eyes (9.1%) showed retinal pigment epithelium damage. The mean angle at the staphyloma edge was 23° ± 12.4° (range 8° to 77°). Larger angles were significant predictors of retinal thinning (adjusted odds ratio: 1.17, confidence interval: 1.09-1.25), and the staphyloma was detected by Optos pseudocolor fundus photography (adjusted odds ratio: 1.08, confidence interval: 1.02-1.15). CONCLUSION: These morphologic findings may provide a basis for exploring the natural evolution of posterior staphyloma as part of the development of pathologic myopia.

PURPOSE: To investigate the relationship between dome-shaped maculas (DSMs) and posterior staphylomas in highly myopic eyes. METHODS: Five hundred and eleven eyes of 291 patients with high myopia (refractive error ≤-8.0 diopters or axial length ≥26.5 mm) were examined by ultra-widefield swept-source optical coherence tomography (UWF-OCT). Posterior staphylomas were identified by detecting the staphyloma edges in the UWF-OCT images. RESULTS: Eighty-two eyes of the 511 highly myopic eyes had a DSM, and a posterior staphyloma was observed in 45 of 82 eyes with a DSM (54.9%) and in 301 of 429 eyes (70.2%) without a DSM. The incidence of staphylomas was significantly lower in eyes with a DSM than those without a DSM (P = 0.007). The wide macular type of staphyloma was the predominant type in eyes with a DSM (31/45 eyes; 68.9%), whereas the narrow macular type and wide macular type of staphylomas were present almost equally in the eyes without a DSM. CONCLUSION: The lack of staphylomas in 45% of eyes with a DSM suggests that DSMs form independently from posterior staphylomas. Dome-shaped maculas tend to occur in eyes with a large expansion of the posterior fundus and should be considered a posterior scleral curvature abnormality.

PURPOSE: To assess the reliability of the atrophy-traction-neovascularization (ATN) classification in patients with pathologic myopia (PM) and its correlation with best-corrected visual acuity (BCVA). METHODS: Cross-sectional study. Hundred highly myopic eyes with a spherical equivalent of >-6.0 diopters or axial length of >26 mm and a total ATN score of ≥3 underwent a complete ophthalmological examination, including fundus photography and swept-source optical coherence tomography. Five observers graded each eye using the ATN system. Mean A, T, and N scores were calculated and correlated with age, BCVA (in logarithm of the minimum angle of resolution), and axial length. Patients were considered to present severe PM if either A or T components were ≥3 and/or N was ≥2. RESULTS: Hundred eyes (53 left) from 91 patients (78 women) were classified. Mean age, BCVA, and axial length values were, respectively, 65.1 ± 11.7 years (range, 36-97 years), -0.63 ± 0.62 (-3.00 to 0.00), and 29.26 ± 2.7 mm (26.01-37.66 mm). Mean ATN grades for each component were as follows: A = 2.51 ± 0.78 (0.6-4.0), T = 0.88 ± 1.14 (0.0-5.0), and N = 1.31 ± 1.40 (0.0-3.0). Weighted interobserver agreement was 98.1%, 98.7%, and 94.6%, for A, T and N, respectively. In eyes with severe PM, BCVA was significantly lower and axial length was significantly longer. CONCLUSION: The excellent interobserver rate in this study demonstrates that the updated ATN grading system is an accurate and reliable tool to classify patients with PM. These findings show that BCVA is more compromised in eyes with severe PM, particularly those graded ≥A3 and/or T3.
