Abstract
Purpose The purpose of this study was to investigate the relationship of posterior staphyloma (PS) types in pathological myopia (PM) with age, best-corrected visual acuity (BCVA), spherical equivalent (SE), axial length (AL), and myopic retinoschisis (MRS) using three-dimensional magnetic resonance imaging (3D-MRI) and optical coherence tomography (OCT). Methods This retrospective, cross-sectional study included 108 eyes of 59 patients with PM from the Henan Eye Institute, China. We classified the PS types based on current international classification criteria and analyzed the risk factors (age, AL, MRS, and BCVA). Results Most of the patients with bilateral PM had the same PS type (80.43%) in both eyes. Complex PS was more common in elderly patients than in younger patients (P < 0.05). Eyes with wide macular PS had a longer AL (P = 0.012) and worse BCVA (P = 0.049) than those with other PS types. MRS was always comorbid with PS (93.33%), and macular PS was the most common (82.14%). Conclusions Complex PS is associated with patient age. PS is related to MRS, and these changes observed by 3D-MRI and OCT affect the prognosis of visual acuity. The 3D-MRI scans shows changes in the eye shape and PS efficiently. Translational Relevance In patients with PM, 3D-MRI can guide the planning of posterior scleral reinforcement.

Progression from Type 2 Macular Neovascularization to Fibrovascular Pigment Epithelial Detachment. Vision (Basel) 2021; 5:vision5020016. [PMID: 33805868 PMCID: PMC8103250 DOI: 10.3390/vision5020016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 03/14/2021] [Accepted: 03/16/2021] [Indexed: 01/18/2023] Open
Abstract
The aim of this study was to report unusual progression of type 2 macular neovascularization (MNV) associated with age-related macular degeneration (AMD), high myopia or angioid streaks. Retrospective multicentric observational case series data were used. Eyes that progressed from type 2 MNV secondary to AMD, high myopia or angioid streaks to fibrovascular pigment epithelial detachment (PED) were included. A total of 29 treatment-naive eyes from 29 patients with type 2 MNV secondary to AMD (n = 14), high myopia (n = 10) or angioid streaks (n = 5) that progressed to a fibrovascular PED on Spectral Domain-Optical Coherence Tomography were used. This progression occurred within 3 months after anti-VEGF therapy initiation. Logarithm of minimum angle of resolution (LogMAR) visual acuity improved significantly after anti-VEGF therapy, from 0.55 (SD ± 0.30) (20/63–20/80) at baseline to 0.30 (20/40) at 3 months, and 0.33 (20/40) at the final follow-up (mean follow up: 3.68 years). Mean number of intravitreal injections per year for patients with a total follow-up ≥ 12 months (n = 24) was 4.3 ± 2.1 per year. Progression from type 2 MNV to a fibrovascular PED may occur in patients suffering from AMD, high myopia or angioid streaks. This progression appears early after initiation of anti-VEGF therapy and is associated with a favorable visual and anatomical outcome, at least on a short follow up basis.

Abstract
PURPOSE To investigate the morphological feature, visual acuity, and prevalence of macular complications in highly myopic eyes with different categories of myopic maculopathy (MM) according to the META-PM classification system. METHODS The clinical records of 1,132 consecutive patients (1,841 eyes) with high myopia (refractive error ≤ -6D and axial length ≥26.5 mm), who visited the High Myopia Clinic at the Zhongshan Ophthalmic Center from January 2014 to July 2017, were reviewed. Fundus photograph, optical coherence tomography, axial length, refractive error, and best-corrected visual acuity were measured in each patient. Myopic maculopathy was graded from fundus photographs according to the META-PM classification, including tessellated fundus (C1), diffuse chorioretinal atrophy (C2), patchy atrophy (C3), and macular atrophy (C4). Other macular complications, including foveoschisis, extrafoveal schisis, full-thickness macular hole, epiretinal membrane, lacquer cracks, Fuchs spot, choroidal neovascularization, macular hemorrhage, and dome-shaped macula, were also investigated. RESULTS Among the 1,841 eyes, 58 (3.15%) had no MM (C0), 779 (42.31%) had tessellated fundus only (C1), 524 (28.46%) had diffuse chorioretinal atrophy (C2), 352 (19.12%) had patchy chorioretinal atrophy (C3), and 128 (6.95%) had macular atrophy (C4). Age increased and best-corrected visual acuity became worse with the severity of MM (P < 0.01). Axial length was significantly longer with the severity of MM from C0 to C3 (P < 0.01), and spherical equivalent was greater with the severity of MM from C0 to C3 (P < 0.01) but was not different between C3 and C4 (P > 0.05). Subfoveal and parafoveal choroidal thicknesses were significantly thinner from C0 to C3 (P < 0.01). However, no significant difference was found between C3 and C4 in parafoveal choroidal thickness (P > 0.05). The complications were different among C0 to C4 correlated with MM (P < 0.01). The complications of foveoschisis, choroidal neovascularization, hemorrhage, lacquer cracks, Fuchs spot, dome-shaped macula, and epiretinal membrane were different between C1 and C2 (P < 0.01), but none of the complications were different between C3 and C4 (P > 0.05) except Fuchs spot (P = 0.009). CONCLUSION The morphological and functional characteristics in eyes with high myopia were positively correlated with the severity of C0 to C3 MM. However, no morphological difference was found between C3 and C4. The absence of the progressive relationship between C3 and C4 might be determined.

Abstract
PURPOSE To evaluate the prevalence and visual outcomes of macular Bruch membrane (BM) defects in patients treated with anti-vascular endothelial growth factors (VEGF) for choroidal neovascularization secondary to pathological myopia (mCNV). METHODS Single-center retrospective observational case series of 68 eyes from 62 patients with mCNV treated with one anti-VEGF injection followed by a pro re nata (1 + PRN) regimen. A minimum follow-up of 6 months was defined. Chorioretinal atrophy was assessed by fundus examination, fluorescein angiography, and SD-OCT. RESULTS Median follow-up was 28.5 (range 6-89) months with a median number of 5 anti-VEGF injections. At baseline, 27.9% of eyes had macular BM defects increasing to 36.8% during follow-up (p<0.001). Eyes without macular BM defects at the baseline had higher BCVA at the last observation than patients with BM defects (p=0.003). An increase of 5 or more ETDRS letters was more frequent in eyes without BM defects (p=0.001). At the end of follow-up, mCNV-related macular atrophy was present in 44.1%; out of which, 83.3% presented macular BM defects (p<0.001). Eyes with mCNV-related macular atrophy without BM defects had a significant increase of best-corrected visual acuity compared with eyes with mCNV-related macular atrophy and BM defect (p=0.002). CONCLUSIONS Macular Bruch membrane defects are often seen in mCNV and have a significant impact in visual acuity and prognosis. Eyes with macular BM defects have a poorer response and worse visual outcomes after anti-VEGF therapy.

Abstract
CLINICAL RELEVANCE Clinicians can benefit from developing an understanding of the natural disease progression of myopic maculopathy in degenerative myopia using optical coherence tomography (OCT). BACKGROUND The prevalence of high myopia is constantly increasing. In this work, infrared imaging and OCT is used to study the natural course of the disease. METHODS This is a retrospective longitudinal study. Medical records of 72 patients with high myopia (< 6.00 D) and a minimum five-year follow-up period were analysed. Collected data on all enrolled patients included demographic characteristics and medical history, as well as recordings on best-corrected visual acuity, slitlamp examination, OCT, and fluorescein angiography in cases of suspected myopic choroidal neovascularisation. Images were independently marked by two graders. RESULTS The mean age of patients was 54.6 ± 14.4 years (59.72% female) with baseline logMAR best-corrected visual acuity of 0.22 ± 0.28. At baseline examination, 70.83% of the study group showed signs of maculopathy and 62.5% diffuse or patchy atrophy. During follow-up, 22.2% of patients with any type of atrophy showed enlarged affected areas. Two patients with baseline lacquer cracks developed new lesions. There was a weak correlation between patient age and maculopathy progression (r = 0.233; p = 0.03). While central retinal thickness was not associated with maculopathy progression (p = 0.203), a moderate correlation was found between choroidal thickness and maculopathy progression (r = -0.516; p < 0.001). CONCLUSION Lesion characteristics in myopic degeneration have been elucidated, taking advantage of the ongoing technological advances in retinal imaging. The understanding of disease patterns and progression is essential for appropriate management of patients, while discovering biomarkers which lead to choroidal neovascularisation development is of urgent importance to establish international diagnostic criteria and treatment protocols.

Abstract
Purpose: To report the 5-year results of chorioretinal atrophy (CRA) progression in patients with punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC).Methods: A retrospective study included PIC/MFC patients with secondary CRA formation. The area of CRA was measured and the progression rate was calculated. Multiple regression analysis was performed to investigate risk factors associated with CRA progression.Results: Forty-five eyes of 36 patients were included. The mean CRA size significantly increased after an average of 4.83 years of follow-up with progression rate of 0.69 mm2/year. Moreover, we had identified the axial length and initial PIC lesion number as significant risk factors for CRA progression.Conclusion: Significant CRA enlargement is noted in PIC/MFC patients after 5 years of follow-up. The progression rate is associated with axial length and initial PIC numbers. Aggressive treatment is suggested for eyes with more initial lesion numbers and longer axial length to control the faster CRA progression.

Abstract
PURPOSE To compare the outcomes of macular buckling (MB) surgery between myopic foveal detachment (FD) eyes with and without ellipsoid zone (EZ) disruption. METHODS A retrospective, case-control study. Forty-four consecutive eyes from 44 patients received MB surgery for myopic FD between November 2017 and January 2019 were included. The eyes were divided into two groups according to the integrity of EZ on spectral-domain optical coherence tomography (SD-OCT): 28 eyes with disrupted EZ band and 16 eyes with intact EZ band. Main outcome measures were visual acuity and the duration of subfoveal fluid (SFF) after MB. RESULTS The mean follow-up time was 17.64 ± 6.61 and 16.06 ± 5.78 months in the disrupted EZ and intact EZ group, respectively (P = 0.430). The logMAR best-corrected visual acuity (BCVA) improved significantly, from 1.13 ± 0.46 and 1.12 ± 0.39 at baseline to 0.85 ± 0.65 (P = 0.002) and 0.53 ± 0.33 (P = 0.000) for the disrupted EZ group and intact EZ group, respectively. The mean visual improvement was 15.00 ± 14.14 Early Treatment Diabetic Retinopathy Study (ETDRS) letters for the disrupted EZ group and 26.88 ± 19.48 ETDRS letters for the intact EZ group. Significant difference was found on both final postoperative BCVA (P = 0.035) and visual improvement (P = 0.025). At 6 months, SFF remained in 53.57% (15/28) of the eyes in the disrupted EZ group and in only 12.50% (2/16) of the eyes in the intact EZ group (P = 0.018). CONCLUSION The intact EZ group showed better functional and anatomical outcomes than the disrupted EZ group after MB surgery.

Front Med (Lausanne) 2021; 7:615902. [PMID: 33425961 PMCID: PMC7785753 DOI: 10.3389/fmed.2020.615902] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Accepted: 11/30/2020] [Indexed: 11/16/2022] Open
Abstract
Purpose: To investigate the morphologic features and identify the risk factors of myopic choroidal neovascularization (CNV). Methods: Eighty-eight eyes of 69 consecutive patients with myopic CNV were included in this study. About 109 eyes of 78 pathologic myopia patients without myopic CNV were randomly selected as the control group. Morphologic features and parameters including scleral thickness (ST), choroidal thickness (CT), posterior staphyloma height and the presence of scleral perforating vessels were obtained and measured by swept-source optical coherence tomography (SS-OCT). Binary logistic regression analysis was performed to identify the risk factors for myopic CNV. Results: Patients with myopic CNV had relatively shorter axial length (P < 0.001) and thicker sclera (P < 0.001) compared to those without. After adjusting age, gender and axial length, thick sclera (OR = 1.333, P < 0.001 per 10-μm increase) and thin choroid (OR = 0.509, P < 0.001 per 10-μm increase) were associated with the presence of myopic CNV. Scleral perforating vessels were detected in the area of myopic CNV in 78.67% of the subjects. Conclusions: A relatively thicker sclera and a thinner choroid are the biological indicators for myopic CNV on SS-OCT. Scleral perforating vessels may also play a pivotal role in the formation of myopic CNV.

Abstract
Background To compare different clinical and Spectral-Domain Optical Coherence Tomography (SD-OCT) features of high myopic eyes with Stickler syndrome (STL) with matched controls. Methods Patients with genetically confirmed STL with axial length ≥ 26 mm and controls matched for axial length were included. The following data were obtained from SD-OCT scans and fundus photography: choroidal and retinal thickness (respectively, CT and RT), peripapillary atrophy area (PAA), presence of posterior staphyloma (PS). Results Twenty-six eyes of 17 patients with STL and 25 eyes of 19 controls were evaluated. Compared with controls, patients with STL showed a greater CT subfoveally, at 1000 μm from the fovea at both nasal and temporal location, and at 2000 and 3000 μm from the fovea in nasal location (respectively, 188.7±72.8 vs 126.0±88.7 μm, 172.5±77.7 vs 119.3±80.6 μm, 190.1±71.9 vs 134.9±79.7 μm, 141.3±56.0 vs 98.1±68.5 μm, and 110.9±51.0 vs 67.6±50.7 μm, always P< 0.05). Furthermore, patients with STL showed a lower prevalence of PS (11.5% vs 68%, P< 0.001) and a lower PAA (2.2±2.1 vs 5.4±5.8 mm2, P=0.03), compared with controls. Conclusions This study shows that high myopic patients with STL show a greater CT, a lower PAA and a lower prevalence of PS, compared with controls matched for axial length. These findings could be relevant for the development and progression of myopic maculopathy in patients with STL.

Abstract
Purpose The purpose of this study was to investigate the two-dimensional peripheral refraction in fellow eyes of patients with isomyopia and anisomyopia. Methods Sixty-eight young adults were recruited, including 25 isomyopes with interocular differences (IODs) of foveal refraction < 1.00 D and 43 anisomyopes with IOD > 1.50 D. Peripheral refraction across an area of the visual field of 60° × 36° with a resolution of 1° was measured using a custom-made Hartmann-Shack wavefront sensor. The retinal area was divided into 3 × 3 zones for comparison between the fellow eyes. Results There was no difference of refraction in all corresponding zones between the fellow eyes in the isomyopic group (all P > 0.05). The IODs between more myopic (MM) eyes and less myopic (LM) eyes in the anisomyopic group ranged from −1.40 to approximately −2.46 D (all P <0.001), which was flagged in the center and attenuated in peripheral zones by varied magnitudes. In the stratification analysis for different levels of anisomyopia, the nasal retina first presented significant relative hyperopic shifts compared to the center, followed by the temporal retina. In contrast, the superior and inferior periphery only differed from the center when the central IOD was greater than 3.00 D. Conclusions The two-dimensional peripheral refraction patterns showed a mirror symmetry between the fellow eyes of a patient with isomyopia. However, in the anisomyopic group, peripheral refraction showed significantly relative hyperopic shift when compared with the center and developed with a varied rate in different areas. These findings may indicate an asymmetrical variation in the peripheral refraction patterns during myopia progression.

Abstract
Purpose: To develop a photographic classification for cilioretinal arteries and to investigate its association with myopic macular degeneration (MMD). Methods: One thousand six hundred ninety-two highly myopic eyes of 1,692 patients were included. The presence of a cilioretinal artery was determined by fundus photographs, and a photographic classification was proposed. MMD was classified according to the International META-PM Classification. Associations of the cilioretinal artery and its classifications with MMD and visual acuity were analyzed. Results: Of the eyes tested, 245 (14.5%) had a cilioretinal artery. The cilioretinal arteries were classified into four categories (temporal “cake-fork,” 35.92%; temporal “ribbon,” 53.47%; “multiple,” 6.53%; “nasal,” 4.08%) and 3 distributions based on whether its visible branches reached the central foveal area. Eyes with cilioretinal arteries had significantly less MMD of grade ≥3 and better visual acuity than those without (P < 0.01). Multiple linear regression analysis showed that younger age, male sex, shorter axial length, and the presence of a cilioretinal artery were associated with better visual acuity in highly myopic eyes (all P < 0.05). The “nasal” category presented more MMD with grade ≥3 and worse visual acuity than the other categories (P < 0.05), whereas the “multiple” category contained no eyes with MMD grade ≥3. The cilioretinal arteries reaching the central foveal area showed less MMD of grade ≥3 and better visual acuity than those not (P < 0.05). Conclusions: We propose a photographic classification for cilioretinal arteries that has good clinical relevance to visual functions. The cilioretinal artery may potentially afford protection against MMD.

Abstract
Purposes: To investigate the patterns of fundus autofluorescence (FAF) in patients with different grades of myopic atrophy maculopathy (MAM).Methods: Patients with MAM who visited Zhongshan Ophthalmic Center from January 2018 to December 2019 were screened. All patients received comprehensive ophthalmologic examinations as well as FAF imaging. The atrophic severity of each eye was identified based on the META-PM classification system, including no myopic retinal lesions (C0), tessellated fundus only (C1), diffuse chorioretinal atrophy (C2), patchy chorioretinal atrophy (C3), and macular atrophy (C4).Results: Eighty-nine consecutive patients with 137 affected eyes were included. Four different autofluorescence (AF) patterns were detected: unremarkable AF (48 eyes in C1 and 18 eyes in C2, 48.2%), compound AF (2 eyes in C1 and 12 eyes in C2, 10.2%), patchy AF defect (5 eyes in C2 and 34 eyes in C3, 28.5%), and macular AF defect (18 eyes in C4, 13.1%). Moreover, AF patterns were significantly correlated with age (r = 0.419, P < .001), best-corrected visual acuity (BCVA) (r = 0.592, P < .001), axial length (AL) (r = 0.529, P < .001), and subfovial choroidal thickness (SFCT) (r = -0.728, P < .001). In addition, with the help of FAF, 14.3% (5/35) of eyes initially categorized as C2 merely based on color fundus photographs (CFP) should be categorized as C3.Conclusions: The severity of FAF in eyes with MAM was significantly correlated with myopic characteristics. FAF might be beneficial for detecting unremarkable patchy chorioretinal atrophy on CFP of MAM.

Fovea-Sparing as Opposed to Total Peeling of Internal Limiting Membrane for Myopic Foveoschisis: A Systematic Review and Meta-analysis. Ophthalmol Retina 2020; 5:670-679. [PMID: 33307217 DOI: 10.1016/j.oret.2020.10.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Revised: 10/14/2020] [Accepted: 10/19/2020] [Indexed: 12/12/2022]
Abstract
TOPIC The effectiveness of fovea-sparing (FS) peeling of internal limiting membrane (ILM) to treat myopic foveoschisis (MF) has not been understood fully. The present meta-analysis aimed to compare postoperative visual and anatomic outcomes between FS peeling and total peeling (TP) of ILM in pars plana vitrectomy for the treatment of MF. CLINICAL RELEVANCE Postoperative macular hole (MH) development is not uncommon and is a serious complication after surgery for MF, with poor visual prognosis. Fovea-sparing peeling of ILM is expected to reduce the risk of postoperative MH; however, no statistically significant evidence exists to prove this hypothesis. In addition, its effect on postoperative visual acuity has not been clear. METHODS MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE were reviewed systematically, and studies that compared FS with total ILM peeling in MF surgery were retrieved. The protocol was registered in International Prospective Register of Systematic Reviews (identifier, CRD42020201675). Primary outcome measures were the postoperative best-corrected visual acuity (BCVA) and frequency of postoperative MH development. Certainty of evidence was evaluated by the Grading of Recommendations Assessment, Development and Evaluation system. RESULTS Eight studies with 300 eyes from 289 patients were included. All studies were nonrandomized and observational. The postoperative BCVA was significantly better in eyes treated with FS (mean difference [MD], -0.15 logarithm of the minimum angle of resolution [logMAR]; 95% confidence interval [CI], -0.24 to -0.05 logMAR; P = 0.002). The risk of postoperative MH was significantly lower in the FS group (odds ratio, 0.19; 95% CI, 0.06-0.56; P = 0.003). No significant difference was found in postoperative central foveal thickness (MD, 12.59 μm; 95% CI, -2.8 to 28.0 μm; P = 0.11). The certainty of evidence regarding lower frequency of postoperative MH after FS peeling was considered moderate, whereas the certainty regarding better postoperative BCVA after FS peeling was judged to be low. DISCUSSION Fovea-sparing peeling may contribute to better visual acuity outcome and lower risk of postoperative MH development in eyes with MF.

Abstract
OBJECTIVES To estimate the prevalence, ethnic differences and associated risk factors of myopic maculopathy in Han and Uygur adults in Xinjiang, China. DESIGN AND SETTING A cross-sectional study with multistage, stratified cluster sampling method was conducted in Xinjiang, China. PARTICIPANTS A total of 4023 Han and Uygur participants aged 40 years and older were eligible for the study. OUTCOME MEASURES The association between myopic maculopathy and its risk factors was screened using the generalised estimating equation (GEE) model. We also investigated whether ethnic differences exist between Han and Uygur populations affected by myopic maculopathy. Myopic maculopathy was defined in accordance with International Photographic Classification and Grading System for Myopic Maculopathy. RESULTS A total of 3044 subjects (5946 eyes) were included in our study (1736 Han and 1308 Uygur individuals). The participants consisted of 1256 (41.3%) men and 1788 (58.7%) women. The average age was 52.2±9.4 years, and the mean spherical equivalent (SE) was -0.18±2.31 dioptre (D). Myopic maculopathy was detected in 198 eyes of 138 participants. The age-adjusted prevalence of myopic maculopathy reached 5.8% (95% CI 4.8 to 6.8). In the GEE model, myopic maculopathy was significantly associated with old age (per year; OR: 1.16; 95% CI 1.13 to 1.19; p<0.001) and myopic SE (per -1 D; OR: 1.48; 95% CI 1.40 to 1.56; p<0.001). No ethnic differences were detected between Han (98, 5.7%) and Uygur population (40, 3.1%) in terms of the prevalence of myopic maculopathy (OR=0.89; 95% CI 0.53 to 1.48; p=0.64). Neither urbanisation (p=0.38) nor the level of education (p=0.92) was associated with myopic maculopathy. CONCLUSIONS A high age-adjusted prevalence of myopic maculopathy was observed in Han and Uygur populations in Xinjiang, China. Old age and high degree of myopic refraction were independent risk factors for myopic maculopathy. No ethnic differences were detected in Han and Uygur populations affected by myopic maculopathy.

Abstract
PURPOSE To evaluate the effect and safety of fovea-sparing internal limiting membrane (ILM) peeling (FSIP) for myopic traction maculopathy comparing with that of total ILM peeling (TP). METHODS PubMed, Web of science, Embase, Cochrane, EBSCO and CNKI, published until January 2020, were searched. Postoperative best-corrected visual acuity (BCVA), postoperative central foveal thickness (CFT), the rate of visual improvement and anatomic success were the main outcome parameters, and the secondary outcome parameters were postoperative complications. Random-effects models were chosen in regard with multi-studies. Standard mean difference (SMD) with 95% confidence interval (CI) and odds ratio (OR) were applied as effect sizes of continuous and binomial data, respectively. RESULTS Six comparative studies involving 193 eyes were included. Better postoperative BCVA was detected in the FSIP group (SMD = -0.39, 95%CI: -0.69 to -0.09, p = 0.01). The FSIP group had a higher rate of vision improvement with statistical significance (OR = 3.86, 95%CI: 1.36 to 10.97, p = 0.01). Both surgical methods had similar outcomes for postoperative CFT (SMD = 0.07, 95%CI: -0.27 to 0.40, p = 0.70). The FSIP group had a higher rate of anatomic success, though there was no obvious significance (OR = 2.54, 95%CI: 0.96 to 6.74, p = 0.06). For the development of postoperative full-thickness macular hole (FTMH), the rate was lower in the FSIP group (OR = 0.18, 95%CI: 0.05 to 0.64, p = 0.008). CONCLUSION Vitrectomy with fovea-sparing ILM peeling for myopic traction maculopathy could gain better visual outcomes and decrease incidence of FTMH development, though there was no obvious difference in postoperative CFT and the rate of anatomic success between two groups.

Abstract
Pathologic myopia (PM) is an ocular disorder characterized by a spherical equivalent (SE) of more than - 6.0 diopters (D) or by an axial length (AL) of more than 26.5 millimeters (mm). PM is associated with myopic maculopathy (MM). The ATN classification describes all the aspects of MM which regroups atrophic, tractional and neovascular consequences to the sclera, choroid and retina of highly myopic eyes. The advent of OCT allowed to define the ultrastructural characteristics of the tractional changes in MM, described by the term myopic traction maculopathy (MTM). They include foveoschisis/maculoschisis/retinoschisis (FS/MS/RS), retinal/foveal detachment (RD/FD), lamellar macular holes (LMH) and full-thickness macular holes (FTMH) with or without RD (MHRD). The MTM staging system (MSS) describes all foveal and retinal changes related to MTM and their natural history interpreting them as different stages of a single progressive disorder. The management of MTM can be just observation for the earliest cases with good vision or surgery for the severe stages with vision loss. There are two possible surgical approaches: ab externo, that acts on the alteration of the scleral shape and includes posterior scleral reinforcement and macular buckle. Ab interno, that targets the alteration of the foveal profile and consists in pars plana vitrectomy with removal of all the epiretinal tractions, maneuvers on the internal limiting membrane, and the use of intravitreal tamponade and laser. As they target two different sides of the same pathology, the two techniques have to be selected on the base of the MTM stage, single or combined.

Abstract
The structure and functions of the choroid have been long acknowledged but the pathophysiology behind various anomalies has been difficult to understand until the advent of optical coherence tomography (OCT). With OCT imaging, choroidal cavitations appear as optically empty spaces between the outer retinal and choroidal layers with attenuation or loss of outer retinal layers. Choroidal cavitations are found in the posterior pole and seen in conditions such as pathologic myopia, north carolina macular dystrophy (NCMD), focal choroidal excavation (FCE), and torpedo maculopathy (TM). To date, these disorders have not been linked. A commonality they all share is malformation of the RPE-photoreceptor-choroid complex. The following report describes the differences and similarities of choroidal cavitation amongst the different retinal disorders and emphasizes the importance of multimodal imaging in the detection and management of potential complications.

Abstract
Purpose To determine the risk between degree of myopia and myopic macular degeneration (MMD), retinal detachment (RD), cataract, open angle glaucoma (OAG), and blindness. Methods A systematic review and meta-analyses of studies published before June 2019 on myopia complications. Odds ratios (OR) per complication and spherical equivalent (SER) degree (low myopia SER < -0.5 to > -3.00 diopter [D]; moderate myopia SER ≤ -3.00 to > -6.00 D; high myopia SER ≤ -6.00 D) were calculated using fixed and random effects models. Results Low, moderate, and high myopia were all associated with increased risks of MMD (OR, 13.57, 95% confidence interval [CI], 6.18-29.79; OR, 72.74, 95% CI, 33.18-159.48; OR, 845.08, 95% CI, 230.05-3104.34, respectively); RD (OR, 3.15, 95% CI, 1.92-5.17; OR, 8.74, 95% CI, 7.28-10.50; OR, 12.62, 95% CI, 6.65-23.94, respectively); posterior subcapsular cataract (OR, 1.56, 95% CI, 1.32-1.84; OR, 2.55, 95% CI, 1.98-3.28; OR, 4.55, 95% CI, 2.66-7.75, respectively); nuclear cataract (OR, 1.79, 95% CI, 1.08-2.97; OR, 2.39, 95% CI, 1.03-5.55; OR, 2.87, 95% CI, 1.43-5.73, respectively); and OAG (OR, 1.59, 95% CI, 1.33-1.91; OR, 2.92, 95% CI, 1.89-4.52 for low and moderate/high myopia, respectively). The risk of visual impairment was strongly related to longer axial length, higher myopia degree, and age older than 60 years (OR, 1.71, 95% CI, 1.07-2.74; OR, 5.54, 95% CI, 3.12-9.85; and OR, 87.63, 95% CI, 34.50-222.58 for low, moderate, and high myopia in participants aged >60 years, respectively). Conclusions Although high myopia carries the highest risk of complications and visual impairment, low and moderate myopia also have considerable risks. These estimates should alert policy makers and health care professionals to make myopia a priority for prevention and treatment.

Abstract
Purpose To examine 2-year progression rate and associated biometric changes in highly myopic eyes. Methods This is a longitudinal, observational cohort study that included 657 participants aged 7 to 70 years with bilateral high myopia (≤-6.00 diopters [D]) and followed for 2 years. All participants underwent ocular biometry and cycloplegic refraction examinations. Main outcome measures were changes in spherical equivalent refraction (SE) and ocular biometry in the right eyes. Results Mean age of participants was 21.6 ± 12.2 years. At baseline, mean SE was -9.82 ± 3.28 D and ocular biometric measurements were 27.40 ± 1.56 mm for axial length, 3.16 ± 0.27 mm for anterior chamber depth, 3.60 ± 0.35 mm for lens thickness, and 20.09 ± 1.50 mm for vitreous chamber depth. After 2 years of follow-up, there was a trend toward more myopia and greater axial elongation in all age groups. Younger participants (≤20 years) had significantly (P < 0.001) greater rates of myopic shift and axial elongation compared with older participants (>20 years). However, highly myopic adults aged 40 to 70 years continued to demonstrate refractive progression, particularly if they had extremely high myopia (≤-10.00 D). In the multiple regression analysis, each additional diopter of myopia at baseline was associated with a 11% higher risk of a >1.00-D/y myopic shift (odds ratio, 1.11; 95% confidence interval, 1.04-1.18; P = 0.002). Conclusions Longitudinal data from this large Chinese cohort suggest that highly myopic eyes continue to progress in SE throughout life, with the greatest rates of progression observed in younger participants. Axial elongation rates appeared to stabilize after 20 years of age and were predominantly due to an increase in the vitreous chamber depth. Other risk factors for a myopic shift included a higher degree of myopic refraction at baseline.

Abstract
AIMS To investigate the progression pattern of diffuse chorioretinal atrophy (DCA) among Chinese participants with high myopia. METHODS This is a longitudinal, non-interventional study. Participants with high myopia, defined as ≤-6 diopters spherical power, were included and followed up for 4 years, and underwent cycloplegic autorefraction, best-corrected visual acuity (BCVA) and fundus photography examinations. Newly established DCA, enlargement of existing DCA and development of other lesions of myopic maculopathy were regarded as DCA progression. RESULTS Of the 484 participants with a mean age of 21.5±12.7 years (range, 6.8-69.7 years), 68 eyes (14.0%) showed DCA progression, with 88 lesion changes. The first appearance of DCA was identified in 21 eyes (23.9%). Of 88 eyes with DCA at baseline, 47 eyes (53.4%) showed progression, with 67 lesion changes, including 45 eyes (67.2%) with enlargement of DCA, 17 (25.3%) with a first appearance of lacquer cracks, 4 (6.0%) with development of patchy chorioretinal atrophy and 1 (1.5%) with increased numbers of lacquer cracks. Longer axial length (p<0.001), baseline DCA (p=0.005) and baseline DCA closer to the fovea (p=0.013) predicted DCA progression. Eyes had poorer BCVA at the follow-up if DCA was enlarging (p<0.001) or DCA was closer to the fovea at baseline (p=0.028) after adjusting for age,gender and cataract. CONCLUSION Approximately half of the participants with DCA had progression over a 4-year follow-up. Enlargement and newly developed DCA were common progression patterns. Larger areas of DCA and foveal involvement with DCA could be indicators of a worse BCVA later.

Abstract
Purpose To examine the 6-year incidence, progression, associated risk factors, and impact of myopic macular degeneration (MMD) in a myopic population in Singapore. Methods We examined myopic (spherical equivalent ≤-0.5 diopters) adults (N = 2157 persons and 3661 eyes) who were phakic at baseline and participated in both baseline and 6-year follow-up visits of the Singapore Epidemiology of Eye Diseases study. Eye examinations, including visual acuity, subjective refraction and axial length (AL) measurements, were performed. MMD was graded from fundus photographs following the META-PM classification. Vision-related quality of life was assessed with Rasch-transformed scores from reading, mobility, and emotional domains of the Impact of Vision Impairment questionnaire. Results The 6-year eye-specific incidence of MMD among myopic eyes was 1.2% (95% CI, 0.9%-1.6%). Older age, worse spherical equivalent, and longer AL at baseline were associated with MMD incidence (all P < 0.001). The 6-year eye-specific progression of MMD in 288 eyes with baseline MMD was 17.0% (95% CI, 12.6%-21.4%). More severe MMD at baseline, worse spherical equivalent, and longer AL (all P < 0.05) were associated with MMD progression. Patients with Meta-PM categories 3 and 4 had worse best-corrected visual acuity and poorer vision-related quality of life outcomes than those without MMD (all P < 0.05). Conclusions Over a 6-year period, one in 80 myopic eyes developed MMD and one in six with existing MMD had MMD progression. Myopia severity and AL were strong predictors of MMD development and progression. Eyes with severe MMD were at higher risk of MMD progression than those with less severe MMD, and were associated with poorer visual acuity and vision-related quality of life.

Abstract
IMPORTANCE Slowing myopia progression could decrease the risk of sight-threatening complications. OBJECTIVE To determine whether soft multifocal contact lenses slow myopia progression in children, and whether high add power (+2.50 D) slows myopia progression more than medium (+1.50 D) add power lenses. DESIGN, SETTING, AND PARTICIPANTS A double-masked randomized clinical trial that took place at 2 optometry schools located in Columbus, Ohio, and Houston, Texas. A total of 294 consecutive eligible children aged 7 to 11 years with -0.75 D to -5.00 D of spherical component myopia and less than 1.00 D astigmatism were enrolled between September 22, 2014, and June 20, 2016. Follow-up was completed June 24, 2019. INTERVENTIONS Participants were randomly assigned to wear high add power (n = 98), medium add power (n = 98), or single-vision (n = 98) contact lenses. MAIN OUTCOMES AND MEASURES The primary outcome was the 3-year change in cycloplegic spherical equivalent autorefraction, as measured by the mean of 10 autorefraction readings. There were 11 secondary end points, 4 of which were analyzed for this study, including 3-year eye growth. RESULTS Among 294 randomized participants, 292 (99%) were included in the analyses (mean [SD] age, 10.3 [1.2] years; 177 [60.2%] were female; mean [SD] spherical equivalent refractive error, -2.39 [1.00] D). Adjusted 3-year myopia progression was -0.60 D for high add power, -0.89 D for medium add power, and -1.05 D for single-vision contact lenses. The difference in progression was 0.46 D (95% CI, 0.29-0.63) for high add power vs single vision, 0.30 D (95% CI, 0.13-0.47) for high add vs medium add power, and 0.16 D (95% CI, -0.01 to 0.33) for medium add power vs single vision. Of the 4 secondary end points, there were no statistically significant differences between the groups for 3 of the end points. Adjusted mean eye growth was 0.42 mm for high add power, 0.58 mm for medium add power, and 0.66 mm for single vision. The difference in eye growth was -0.23 mm (95% CI, -0.30 to -0.17) for high add power vs single vision, -0.16 mm (95% CI, -0.23 to -0.09) for high add vs medium add power, and -0.07 mm (95% CI, -0.14 to -0.01) for medium add power vs single vision. CONCLUSIONS AND RELEVANCE Among children with myopia, treatment with high add power multifocal contact lenses significantly reduced the rate of myopia progression over 3 years compared with medium add power multifocal and single-vision contact lenses. However, further research is needed to understand the clinical importance of the observed differences. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02255474.

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
The visual outcome of myopic choroidal neovascularization (CNV) after anti-vascular endothelial growth factor (anti-VEGF) therapy varies among individuals. We retrospectively analyzed the data of 24 eyes (24 patients) with treatment-naïve myopic CNV who underwent anti-VEGF monotherapy following a pro-re-nata regimen at the Division of Medical Retina Clinic, Department of Ophthalmology, Keio University Hospital between May 2014 and December 2017. The mean age was 70.6 ± 2.1 years, and 16 (66.7%) patients were female. Overall, the mean best-corrected visual acuity (BCVA) improved (p = 0.034), and the mean height of the hyperreflective material (HRM), involving the CNV lesion recorded by optical coherence tomography, decreased (p < 0.01) 12 months after the initial treatment. Fifteen eyes (62.5%) achieved a BCVA of better than 0.10 in LogMAR at 12 months; they had a better BCVA (p = 0.015) and lower HRM intensity (p = 0.033) at baseline than the others. Remarkably, the BCVA improved (p < 0.05) and the HRM height (p < 0.01) decreased only in eyes with a final BCVA better than 0.10 as early as 1 month after the initial treatment, which was still present at 12 months. The HRM height and intensity, not only the BCVA, would be valuable in evaluating the prognosis of myopic CNV after anti-VEGF therapy, although further study is required.

Abstract
PURPOSE To characterize the choriocapillaris (CC) in highly myopic eyes with myopic maculopathy, using optical coherence tomographic angiography. METHODS Prospective, clinic-based study of 42 eyes of 38 patients with high myopia (≤-6 diopters and axial length ≥26.5 mm). Myopic maculopathy was graded from fundus photographs according to the Meta-Analysis for Pathologic Myopia classification. Macular 3 × 3 mm en face optical coherence tomographic angiographic images were obtained with swept-source optical coherence tomographic angiography and graded for CC flow impairment as follows: 1) intact CC, 2) focal (<1 mm), and 3) extensive (>1 mm). RESULTS Of the 42 eyes, 17 (39.5%) had tessellated fundus, 20 (46.5%) had diffuse, and 6 (14.0%) had patchy atrophy. Choriocapillaris flow impairment was observed in all eyes with diffuse and patchy atrophy. Even in eyes with tessellated fundus only, CC signal voids were seen in 3 eyes (17.6%). With increasingly severe myopic maculopathy, the pattern of CC flow impairment changed from predominantly focal to predominantly extensive. CONCLUSION Choriocapillaris flow impairment was observed in many highly myopic eyes, even in those with mild fundus changes, and worsened with increasing severity of myopic maculopathy. Longitudinal studies are needed to assess whether CC flow impairment predicts the risk of myopic maculopathy progression.

Abstract
PURPOSE To investigate the clinical features of simple hemorrhage (SH) and myopic choroidal neovascularization (mCNV) lesions in pathologic myopia (PM) accompanied with lacquer cracks (LCs). METHODS Altogether 105 PM subjects were recruited with fifty-eight eyes categorized as group LC + SH and sixty eyes as group LC + mCNV. LCs were categorized into stellate and linear subtypes. Eye fundus photography, optical coherence tomography, fluorescein angiography, and indocyanine green angiography were performed. Clinical demographic data, PM maculopathy, peripapillary atrophy, and macular choroidal thickness (mCT) were documented. RESULTS Significant differences in age, gender, BCVA, and PM atrophies were observed between LC + SH and LC + mCNV groups. The stellate LC was more common in elder subjects with more severe chorioretinal atrophy and thinner mCT compared with linear LCs (P < 0.05). The mCT in group LC + SH was significantly larger than group LC + CNV (P < 0.001), especially in temporal, inferior, and superior locations of macula. The mCT showed correlation with age (P < 0.001)with a decreasing rate of 0.696 μm/year. CONCLUSIONS SH tended to initially occur in younger subjects with linear LCs. mCNV was more common in elder subjects with severe chorioretinal atrophy. Stellate LCs were associated with the worse PM lesions.

Abstract
Pathologic myopia is a major cause of low vision and blindness worldwide. Its social and economic burden has been demonstrated by epidemiological studies. There have been recent advances in the classification system for myopic maculopathy that enables clinicians to describe different types of lesions, including tessellated fundus, diffuse/patchy chorioretinal atrophy, macular atrophy, lacquer cracks, choroidal neovascularization (CNV), and Fuchs' spot, in a standardized format. From a therapeutic point of view, anti-vascular endothelial growth factor therapy has been established as first-line choice for myopic CNV. For myopic retinoschisis and macular holes with/without retinal detachment, pars plana vitrectomy has been generally accepted as an efficient strategy. Studies are being conducted to determine how to avoid the development of a postoperative macular hole and to improve the quality of vision after surgery. In recent years, studies have revealed preventive measures that can be taken against myopia progression, including low-dose atropine eyedrops and contact lens wearing with peripheral myopic defocusing.

[PMID: 32564136 DOI: 10.1007/s00417-020-04795-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 06/01/2020] [Accepted: 06/06/2020] [Indexed: 11/27/2022] Open
Abstract
PURPOSE This study aims to determine the probability of progression of myopic maculopathy according to age. METHODS This is a longitudinal observational study of single-center retrospective cohort of Caucasian patients formed by 212 consecutive adults with high myopia. Main outcome measures were age, visual acuity (VA), refractive error (RE), follow-up time, and the macular status assessed at least 5 years apart according to the Meta-Analysis of Pathologic Myopia Study Group. The progression rate was calculated based on per 1000 eyes/year. Multistate models were fitted to identify the predictive factors and to calculate the most probable age of progression onset using the Aalen-Johansen estimator. RESULTS We studied 220 eyes of 122 Caucasian patients. Mean age was 48.18 ± 14.1, mean follow-up 12.73 ± 5.81 years. One-hundred and fifty-two (69.1%) eyes progressed of category, and 96 (44%) worsened a mean of 0.3 logMAR units during follow-up. The progression rate was 32.21/1000 eyes/year. The probability of progressing increased with age; it was higher in women if there was a family history of myopia, worse VA, higher RE, or wide macular staphyloma. The probability of progressing from category 1 was > 0.6 after 70 years of age; from category 2, it was 0.7 after 70 years; and 0.5 from category 3 after 75 years. If choroidal neovascularization (CNV) appeared, this probability exceeded 0.7 between ages 45 and 55 for all categories. CONCLUSION The progression rate is lower than in a Japanese series. The vision worsened with disease progression, and the probability of both happening increased after the age of 70-75. If CNV appears, the risk of progression is very high at the age of 45-55.

Results of Ranibizumab Treatment of the Myopic Choroidal Neovascular Membrane according to the Axial Length of the Eye. J Ophthalmol 2020; 2020:3076596. [PMID: 32454987 PMCID: PMC7243022 DOI: 10.1155/2020/3076596] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Revised: 02/17/2020] [Accepted: 03/24/2020] [Indexed: 11/17/2022] Open
Abstract
Aim A retrospective evaluation of the results of treatment of myopic choroidal neovascularization (mCNV) with intravitreal injections of ranibizumab in a pro re nata (PRN) regimen in three groups of patients distributed according to axial length. Methods The paper presents a retrospective multicenter study carried out with the cooperation of several Departments of Ophthalmology in the Czech Republic. The study included 60 eyes of 60 patients suffering from mCNV, divided according to axial length into three groups. The first group consisted of 20 patients with an axial length of the eyes shorter than 28 mm (Group 1), the second group included 27 patients with axial lengths ranging from 28 mm to 29.81 mm (Group 2), and 13 patients had axial lengths longer than 30 mm (Group 3). All patients were first administered 3 initial intravitreal ranibizumab injections at monthly intervals (loading phase), and other injections were administered according to a PRN treatment regimen. Patients were evaluated before treatment and then at intervals of 3, 6, 9, and 12 months. The effect of ranibizumab treatment on the functional and morphological parameters of the affected eye was evaluated. Results The average baseline BCVA ± SD in Group 1 was 52.6 ± 12.5 letters of ETDRS optotypes, and at the end of the one-year follow-up, it was 63.3 ± 11.8 letters. The average baseline of CRT ± SD in this group was 377.4 ± 80.0 μm, and in the 12th month, it was 311.1 ± 63.7 μm. The average baseline BCVA ± SD in Group 2 was 50.2 ± 9.0 ETDRS letters, and at the end of the follow-up, it was 60 ± 12.4 letters. The average baseline of CRT ± SD in Group 2 was 391.2 ± 85.2 μm, and in the 12th month, it was 323.9 ± 91.2 μm. In Group 3, the average baseline of BCVA was 48.5 ± 14.5 ETDRS letters, and at the end of the one-year follow-up, it was 55.7 ± 16.1 letters. The average baseline CRT ± SD for Group 3 was 342.1 ± 94.9 μm, and after 12 months, it was 287.8 ± 88.4 μm. An improvement of BCVA by ≥15 letters of ETDRS optotypes was achieved by 3 patients of 20 (15%) in Group 1, by 5 patients of 27 (18.5%) in Group 2, and by 3 patients of 13 (23.1%) in Group 3. All these changes were statistically significant in comparison with the input values (p < 0.05). Conclusion Ranibizumab treatment in patients with mCNV in our study resulted in statistically significant improvement in BCVA and a decrease in CRT in all groups of patients. Our results from a routine clinical practice correspond with the results of large clinical studies; we confirm a particularly good effect of treatment in patients with axial lengths of the eye smaller than 28 mm.

Abstract
PURPOSE To describe visual performance in high myopia. METHODS In this cross-sectional study, 148 emmetropes [spherical equivalent (SE) - 0.50 to + 1.00 D] and 564 high myopes [SE ≤ - 6.00 D] were categorised into three groups (Group 1: SE - 6.00 to > - 8.00 D; Group 2: SE - 8.00 to > - 10.00 D; and Group 3: SE ≤ - 10.00 D). Multivariate regression analyses adjusting for age and ethnicity examined the relationship between corrected distance visual acuity (CDVA) [photopic, mesopic and super vision test-night vision goggles (SVT-NVG)] and contrast sensitivity (CS)] (mesopic and SVT-NVG) with SE and axial length (AL). RESULTS Mean age of subjects was 21.07 ± 1.17 years, and majority were Chinese (91.9%). Mean SE was 0.10 ± 0.23 D (emmetropes) and - 8.76 ± 2.04 D (high myopes), p < 0.001. Higher degrees of myopia were associated with reduced CDVA and CS, and increased AL (all p < 0.001). Among high myopes, Group 1 had the highest proportion of subjects with good CDVA (photopic ≤ 0.00 LogMAR, mesopic ≤ 0.00 LogMAR and NVG ≤ 0.10 LogMAR) and CS (mesopic ≥ 0.75 LogCS and NVG ≥ 0.35 LogCS) compared with Groups 2 and 3 (all p < 0.001). Among high myopes with good VA (photopic ≤ 0.00 LogMAR, mesopic ≤ 0.00 LogMAR and NVG ≤ 0.10 LogMAR), Group 1 also had the highest proportion of subjects who achieved mesopic ≥ 0.75 LogCS and NVG ≥ 0.35 LogCS (both p < 0.001). Multivariate analyses demonstrated that reduced VA and CS were associated with decreased SE and increased AL (all p < 0.001). CONCLUSIONS High myopia is associated with reduced VA and reduced CS.

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
Purpose To determine the relationship between funduscopic findings in myopic eyes and the prevalence and structure of the conus in the optical coherence tomographic (OCT) images. Methods A prospective observational cross-sectional study of 121 right eyes of 121 young healthy volunteers. All participants underwent color fundus photography (CFP), scanning laser ophthalmoscopy, and OCT. Based on the OCT analyses, the area between the edge of the ellipsoid zone (EZ) and that of choroid was defined as the “choroidal conus (CC)”, and the area between the edge of the choroid and the scleral edge as the “scleral conus (SC)”. The eyes were classified into three groups such as the non-conus (NC) group, CC group, and SC group. The differences in the axial length, optic disc tilt, ovality ratio, papillomacular position angle, and peripapillary nerve fiber elevation (pNFE) between the three groups were determined. Results CFPs detected a conus in 79 eyes (65.3 %). The outer border of the conus in CFPs corresponded with the edge of the EZ in the OCT in all subjects. Thirty-seven eyes had CC alone (CC group) and 42 eyes had both CC and SC (SC group). The CC and SC groups had longer axial lengths and more frequent pNFEs than the NC group. There was a significant difference in the optic disc tilt and ovality ratio between the CC and SC groups. Conclusions The eyes with SC tend to have larger optic disc tilt and smaller ovality ratio than the eyes with CC only.

Abstract
Purpose To investigate the retinal sensitivity of highly myopic eyes with chorioretinal patchy atrophy (PA) using microperimetry. Methods Fifty-two eyes of 32 patients with high myopia were prospectively included. Twenty-two eyes of 16 patients had PA lesions; eyes without PA were analyzed as controls. Testing points on microperimetry in eyes with PA were designated as 3 zones: zone 1 as the PA lesion including its borders; zone 2 including testing points adjoining PA; zone 3 including all other testing points. Results In the PA group, the mean retinal sensitivity in zone 1 was 2.1 ± 2.8 dB, zone 2 = 8.3 ± 4.3 dB, and zone 3 = 9.4 ± 4.1 dB. Sensitivity in zone 1 was significantly reduced than zones 2 and 3 (P < 0.001). The mean retinal sensitivity in the PA group was lower than controls (6.5 ± 4.3 vs 13.9 ± 4.1 dB, P < 0.001), and combined zone 2 and 3 in the PA group also presented lower retinal sensitivity (8.8 ± 4.0 dB). Conclusions Eyes with PA generate patchy scotoma in PA lesions and reduced retinal sensitivity in regions beyond atrophic lesion on microperimetry. The presence of PA may be an indicator to reflect both significantly anatomical and functional alterations on myopic macular degeneration.

Abstract
Myopia, and especially high myopia, is associated with a number of posterior segment changes that are considered to be mostly a consequence of the increased axial elongation. This can result in mechanical strain, attendant vascular changes, stretching and thinning of tissues, and atrophy/deformation of tissues in later or more advanced stages. Such myopia-related changes are observed as changes and/or abnormalities in the vitreous, choroid, retina and peripheral retina, sclera and/or optic disc. Although many of these changes are benign, at times they may be associated with significant vision impairment that either requires active intervention or may suggest future progression of the disease. This review systematically addresses the posterior segment conditions seen in myopic eyes, describes the features associated with the condition and details management pathways.

Abstract
Background: Tessellated fundus refers to a specific change in the appearance of the internal layers of the eye in which the choroidal large vessels became visible through polygonal hypopigmented areas. Such hypopigmented areas alternate with hyperpigmented zones in a tigroid pattern. Fundus tessellation is often associated with myopia and choroidal thinning.Materials and Methods: We analyzed fundus images from 50 children with Down syndrome and 52 controls.Results: Tessellation was present in 64% of children with Down syndrome, compared with only 13.5% of controls (p < .0001). In most cases, tessellation was located peripapillary, and no difference was observed in tessellation localization between children with Down syndrome and controls (p = .60). Although more prevalent in myopic children with and without Down syndrome, tessellation was present in almost half (48%) of children with Down syndrome with hyperopia versus only 5% of controls with the same refractive status.Conclusions: Mechanical stretching of the choroid could explain the high rate of tessellation in myopes. Other factors must contribute to the higher prevalence of tessellated fundus in children with Down syndrome without myopia. We discuss potentially relevant factors and propose vascular involvement as a contributor to tessellation in our population with Down syndrome. Further studies assessing choroidal vasculature in individuals with Down syndrome are needed to confirm this theory.

Br J Ophthalmol 2020; 105:103-108. [PMID: 32161005 DOI: 10.1136/bjophthalmol-2019-315763] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2020] [Revised: 02/20/2020] [Accepted: 02/27/2020] [Indexed: 11/04/2022]
Abstract
PURPOSE To assess the incidence, clinical features and predictive risk factors of subretinal fibrosis after treatment of active myopic choroidal neovascularisation (mCNV) with anti-vascular endothelial growth factor (VEGF). METHODS This post-hoc analysis of a randomised controlled trial included a total of 54 patients with active mCNV. The clinical data at baseline, month 3 and month 12 were used. Fundus photography and optical coherence tomography at month 3 were used to determine the presence of subretinal fibrosis after anti-VEGF therapy, and its incidence was calculated. Best-corrected visual acuity (BCVA), Visual Function Questionnaire-25 score, macular integrity index (MI) and their changes were compared between eyes with and without subretinal fibrosis. A logistic regression model was used to evaluate the risk factors of subretinal fibrosis. RESULTS Subretinal fibrosis occurred in 22 of 54 eyes with mCNV. Patients with subretinal fibrosis achieved similar BCVA improvement in comparison with those without fibrosis at 3 and 12 months after the treatment; however, they had lower visual acuity, more subfoveal CNV (p=0.002), higher CNV thickness at baseline (p=0.016), larger CNV size (p=0.030), larger leakage area (p=0.021) and higher presence of advanced myopic maculopathy (p=0.035). Age <45 years, BCVA <60 ETDRS letters, and MI index <20 at baseline were the predictors for subretinal fibrosis occurrence in a logistic regression model. CONCLUSIONS The incidence of subretinal fibrosis after anti-VEGF therapy was 40.7% in eyes with mCNV. Age, baseline BCVA and MI index could serve as predictive risk factors of subretinal fibrosis after anti-VEGF treatment in patients with mCNV.

Abstract
BACKGROUND AND OBJECTIVE To evaluate the relationship between spherical equivalent (SE) refractive error and myopia-related peripheral retinal changes (MPRCs) and to find the optimal cutoff for screening myopic teenagers. PATIENTS AND METHODS The study included 2,286 myopic subjects who had a dilated fundus examination between 1998 and 2011 and SE of -4.0 diopters (D) or higher in both eyes. RESULTS Ninety-five subjects (4.16%) had MPRCs. Two subjects (0.09%) had moderate-to-severe MPRCs. A significant correlation (P < .0001) between SE and MPRC was found. The highest sum of sensitivity (72.63%) and specificity (73.44%) was achieved when a SE of -6.25 D in the more myopic eye was utilized as the cutoff. CONCLUSIONS SE and MPRCs are highly associated. The optimal cutoff to detect MPRC in teenagers is -6.25 D. However, using a SE of -4.0 D as the cutoff may be the practical choice for screening due to the noninvasiveness nature and low cost of the examination.

Abstract
PURPOSE To explore the associations between diffuse chorioretinal atrophy (DCA) and age, sex, axial length, spherical equivalent, and best-corrected visual acuity (BCVA) among highly myopic eyes. METHODS This study included right eyes of 857 bilaterally highly myopic individuals from the ZOC-BHVI Cohort Study. Participants underwent examinations, including BCVA, ocular biometry, autorefraction, and color fundus photography. An Early Treatment Diabetic Retinopathy Study grid was applied on the fundus photographs to evaluate the location of DCA, which was graded into four categories (D0-D3). The characteristics and ocular biometry were compared between participants' eyes with and without DCA. RESULTS Diffuse chorioretinal atrophy was found in 177 (20.6%) eyes. The proportion of participants with DCA in age groups of 7 to 11, 12 to 18, 19 to 39, and ≥ 40 years old was 20.9%, 9.2%, 23.1%, and 52.9%, respectively. The proportion of DCA significantly increased with longer axial length and worse myopic spherical equivalent. Eyes with DCA had poorer BCVA (Snellen visual acuity 20/36, logarithm of minimal angle of resolution 0.26 ± 0.25) than those without DCA (Snellen visual acuity 20/23, logarithm of minimal angle of resolution 0.06 ± 0.14) (P < 0.001). The BCVA gradually declined as the lesion got closer to the fovea (P for trend < 0.001). CONCLUSION The proportion of DCA increased with older age, longer axial length, and more myopic spherical equivalent. Diffuse chorioretinal atrophy is a vision-threatening complication of high myopia where BCVA gradually worsens with foveal involvement.

Abstract
PURPOSE To determine the incidence and long-term outcome of macular atrophy (MA) after pars plana vitrectomy (PPV) in pathologic myopia. METHODS Highly myopic patients who underwent PPV for myopic traction maculopathy and macular hole retinal detachment at Tokyo Medical and Dental University between 2012 and 2016 were studied. Fundus photographs and/or optical coherence tomography were examined before and after PPV at every visit. RESULTS A total of 133 eyes were followed for 39 months with the mean age of 62.8 years and the mean axial length of 30.0 mm. Postoperatively, 14 eyes (10.5%) developed fovea-centered MA, observed initially as a small, isolated, whitish lesion at the center of fovea at 3.5 months after PPV. The appearance of the MA was distinctly different from the choroidal neovascularization-related MA or patchy atrophy-related MA. With time, the lesions enlarged circumferentially. In these 14 eyes, the final best-corrected visual acuity was worse than the baseline, although the difference was not significant. The occurrence of MA was significantly associated with the preoperative foveal status. CONCLUSION The development of MA can occur in 11% of highly myopic eyes after PPV for myopic traction maculopathy and macular hole retinal detachment. This postoperative MA might be a new complication of pathologic myopia.

Abstract
Purpose To investigate structural changes in the retinal outer layers and choroid using adaptive optics (AO) and optical coherence tomography (OCT) in eyes with myopia, and to correlate the changes with decreased macular light sensitivity (MLS). Methods This prospective study included 27 subjects with emmetropia and low myopia (EM/LM), 25 with moderate myopia (MM), and 25 with high myopia (HM). Microperimetry was used to quantify MLS in each subject, while AO and OCT images of fundus were analyzed to quantify cone density and regularity and thickness of outer retinal sublayers and choroid. Differences of MLS, cone distribution, and chorioretinal thicknesses were compared among the three groups, and the associations among photoreceptor morphological alterations, MLS, and other parameters were analyzed. Results In HM, the MLS, cone density and regularity, and thicknesses of the myoid and ellipsoid zone (MEZ), Henle fiber layer and outer nuclear layer, interdigitation zone and RPE/Bruch complex, and choroid were lower than in EM/LM. Decreased MLS was correlated with lower cone density and regularity, and thinner MEZ and choroid in the inner region, and with lower cone density, thinner MEZ and choroid, and longer axial length in the outer region. Multivariate regression showed that better MLS was correlated with thicker MEZ in the inner region and with higher cone density in the outer region. Conclusions Altered cone distribution and outer retinal thickness, especially cone density and MEZ thickness, were significantly correlated with decline of MLS in HM, which may help to evaluate and monitor visual impairment in HM.

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
Purpose: Corneal collagen cross-linking by ultraviolet light activation of riboflavin has been used clinically to enhance corneal stiffness. We sought to determine if cross-linking differentially affects scleral regions.Methods: Adjacent, parallel strips of sclera were cut from superolateral, superomedial, inferolateral, and inferomedial quadrants of posterior and equatorial sclera of 12 human cadaver eyes. One of each pair served as control while the other was cross-linked by immersion in 0.1% riboflavin and 365 nm exposure at 6 mW/cm2 irradiance for 30 min. Behavior of strips was characterized using a microtensile load cell. Preloaded strips were imaged using orthogonally mounted cameras and optical coherence tomography to determine specimen dimensions including cross-sectional area. Tension was measured during 0.1 mm/s constant rate elongation.Results: Young's modulus (YM), the slope of the relationship relating tensile stress to strain, was calculated at 8% strain, and increased significantly after cross-linking (P < .001). In posterior sclera, mean (± standard error of mean, SEM) YM is increased in the superolateral, superomedial, inferolateral, and inferomedial quadrants by 46 ± 15%, 32 ± 11%, 67 ± 20%, and 53 ± 11%, respectively. In equatorial sclera, YM is increased by 139 ± 43%, 68 ± 27%, 143 ± 92%, and 68 ± 14%, respectively. The YM of pooled equatorial quadrants increased significantly more than that of the pooled posterior quadrants.Conclusions: Scleral collagen cross-linking by ultraviolet activation of riboflavin differentially increases scleral YM more in the equatorial than posterior sclera, and most in the lateral, equatorial sclera. Cross-linking might be used to arrest progressive myopia or to prevent staphyloma formation.

Abstract
PURPOSE To compare the outcomes of vitrectomy with fovea-sparing internal limiting membrane peeling (FSIP) and complete internal limiting membrane peeling (ILMP) for myopic traction maculopathy (MTM). STUDY DESIGN A retrospective, observational study. PATIENTS AND METHODS In this study, we included 22 eyes of 21 consecutive patients who underwent vitrectomy with FSIP or ILMP for MTM and were monitored for at least 6 months. Eleven eyes were treated with FSIP, and 11, with ILMP. RESULTS With FSIP, the postoperative best-corrected visual acuity (BCVA) significantly improved from 0.61 (20/82) to 0.34 (20/44; P = .009) logarithm of the minimum angle of resolution (logMAR) units. With ILMP, the postoperative BCVA improved from 0.65 (20/89) to 0.52 (20/66) logMAR units, but was not significant (P = .106). The postoperative final central foveal thickness (CFT) reduced significantly after FSIP (from 557.6 to 128.8 µm, P = .003) and ILMP (from 547.3 to 130.3 µm, P = .008). The postoperative incidence of a macular hole was 0% (0/11 eyes) with FSIP and 27.3% (3/11 eyes) with ILMP. All patients with a macular hole had foveal detachment in association with a thin fovea preoperatively. With ILMP, postoperative BCVA with a macular hole worsened by -3.5 letters; in contrast, postoperative BCVA without a macular hole improved by +10.5 letters. With FSIP, postoperative BCVA without a macular hole significantly improved by +13.5 letters (P = .009). CONCLUSIONS FSIP resulted in significant improvement in MTM and prevented postoperative macular hole development.

Abstract
Purpose To compare one-year treatment outcomes of intravitreal aflibercept (IVA) and intravitreal ranibizumab (IVR) for treatment of myopic choroidal neovascularization (mCNV). Methods The medical records of a total of 30 eyes diagnosed with mCNV and underwent IVA or IVR treatment for a minimum one-year follow-up were studied retrospectively. All the subjects had an axial length >26 mm and received a 1 + PRN (pro re nata) regimen IVA or IVR. Best-corrected visual acuity (BCVA) and central macular thicknesses (CMT) on optical coherence tomography were evaluated before and after treatment. Results There were 12 eyes in IVA group, with a mean age of 60.0 ± 10.2 years. The mean BCVA significantly improved from baseline 1.54 ± 0.76 to 0.85 ± 0.61 and the mean CMT significantly decreased from baseline 384.3 ± 119.1 μm to 305.9 ± 75.4 μm to 305.9 ± 75.4 p : 0.024 and p : 0.024 and μm to 305.9 ± 75.4 μm to 305.9 ± 75.4 p : 0.024 and p : 0.024 and p : 0.024 and p : 0.024 and. Conclusions Both IVA and IVR treatment modalities resulted in similar anatomical outcomes but IVA had better visual outcomes in treatment of mCNV.

Abstract
Background and Objective:
Myopia is one of the most prevalent vision conditions caused by a mismatch between the refractive power and axial length of the eyeball. High myopia may have a degenerative disorder, including cornea, sclera, choroid, optic disc, vitreous, macula, and peripheral retina. Although there are few studies regarding clinical features of pathological myopia, especially in the far-eastern countries where myopia is common, but are no comprehensive data in our region. This study was aimed to demonstrate both anterior and posterior ocular segment manifestations of pathological myopia.
Methods:
One hundred forty eyes of 82 patients who met the pathological myopia criteria were enrolled in this prospective study. Measurements of Central Corneal Thickness (CCT), endothelial cell parameters, Anterior Chamber Depth (ACD), Axial Length (AL) and Subfoveal Choroidal Thickness (SFCT) were performed in all patients. Presence of posterior segment pathologies such as peripapillary atrophy, tilted disc, Lacquer's crack, foveoschisis, myopic maculopathy, Choroidal Neovascularization (CNV), and peripheral retinal degeneration was recorded.
Results:
The mean age was 54.1 ± 14.2 years. 43 (52.4%) of the patients were female. One hundred patients (71.4%) were phakic and 40 (28.6%) were pseudophakic. The mean CCT, corneal endothelial cell density, ACD, AL, and SFCT were 548.91 ± 43.44 µm, 2335.89 ± 374.38 cells/mm2, 3.93 ± 0.79 mm, 28.75 ± 2.20 mm, and 94.56 ± 73.11 µm, respectively. Tilted disc, peripapillary atrophy and posterior staphyloma were detected in 89 (63.6%), 119 (85%) and 78 (55.7%) eyes, respectively. Normal fundus, tessellated fundus, diffuse chorioretinal atrophy, focal chorioretinal atrophy and macular atrophy were seen in 13 (9.3%), 59 (42%), 26 (18.6%), 14 (10%), and 28 (20%) eyes, respectively. Lacquer crack, CNV, and Fuchs spot were observed in 11 (7.9%), 39 (27.9%), and 47 (33.6%) eyes, respectively.
Conclusion:
This study reported clinical characteristics of eyes with pathological myopia in a retina specialty clinic at a tertiary referral center from the Turkish Aegean Region. Pathological myopia may affect both anterior and posterior ocular segments. However, posterior segment manifestations may be associated with lesions that threaten vision. Therefore, periodic follow-up in patients with pathological myopia is critical.

Abstract
The incidence of myopia is increasing worldwide, and the investigation on pathophysiology of myopia is becoming more important. This retrospective study aimed to compare the thicknesses of individual retinal layers between high-myopic and control eyes, and to evaluate the effects of age and sex on each retinal layer thickness. We assessed 164 subjects and divided them into two groups based on axial length (AL) (i.e., high-myopic group (AL ≥ 26 mm) and control group (AL < 26 mm)). Individual retinal layer thicknesses of five subfields in the macula were measured using automated retinal segmentation software packaged with the spectral-domain optical coherence tomography and were compared. In high-myopia group, the thicknesses of total retina and all individual retinal layers in central and entire perifoveal subfields were significantly thicker than the corresponding layers in control group after adjustment for ocular magnification (all P < 0.05). There were no significant effects of sex on individual retinal thicknesses, and age had less negative effects on the thicknesses of retina layers in high-myopic eyes than normal eyes. Axially elongated, non-pathologic highly myopic eyes had different structural features than control eyes, with significantly greater individual macular layer thicknesses independent of sex or age.

Abstract
Background: The Myopia Outcome Study of Atropine in Children (MOSAIC) aims to explore the efficacy, safety, acceptability and mechanisms of action of 0.01% unpreserved atropine for myopia control in a European population. Methods: MOSAIC is an investigator-led, double-masked, placebo-controlled, randomised clinical trial (RCT) investigating the efficacy, safety and mechanisms of action of 0.01% atropine for managing progression of myopia. During Phase 1 of the trial, 250 children aged 6-16 years with progressive myopia instil eye drops once nightly in both eyes from randomisation to month 24. From month 24 to 36 participants are re-randomised in Phase 2 of the trial, into continued 0.01% atropine, and washout, at 1:1 ratio for those participants initially randomised to the intervention arm (n=167), during which any potential rebound effects on cessation of treatment will be monitored. All participants initially assigned to the placebo (n=83) crossover to the intervention arm of the study for Phase 2, and from month 24 to 36, instil 0.01% atropine eye drops in both eyes once nightly. Further treatment and monitoring beyond 36 months is planned (Phase 3) and will be designed dependent on the outcomes of Phase 1. Results: The primary outcome measure is cycloplegic spherical equivalent refractive error progression at 24 months. Secondary outcome measures include axial length change as well as the rebound, safety and acceptability profile of 0.01% atropine. Additional analyses will include the mechanisms of action of 0.01% atropine for myopia control. Conclusions: The generalisability of results from previous clinical trials investigating atropine for myopia control is limited by the predominantly Asian ethnicity of previous study populations. MOSAIC is the first RCT to explore the efficacy, safety and mechanisms of action of unpreserved 0.01% atropine in a predominantly White population.
