Introduction: The aim of this study was to explore the association between parental myopia and high myopia with children's refraction and ocular biometry in large-scale Chinese preschool children from the Beijing Hyperopia Reserve Study.
Subjects/methods: This cross-sectional kindergarten-based study enrolled children aged 3-6 years. Cycloplegic refraction, axial length (AL), and corneal radius (CR) were measured for all children. Parents were asked to complete a questionnaire about refractive status (no myopia, mild myopia <-3 D, moderate myopia ≥-3 D and ≤-6, and high myopia >-6 D).
Results: The study enrolled 2,053 children (1,069 boys and 984 girls), with a mean age of 4.26 ± 0.96 years and mean spherical equivalent refraction (SER) of 1.11 ± 0.97 diopter. Of the children, 90.7% had at least one myopic parent, and 511 children (24.9%) had at least one highly myopic parent. SER decreased significantly with increasing severity of parental myopia (p < 0.001). Preschool children's myopia was independently associated with parental myopia (OR, 10.4 and 11.5 for one and two highly myopic parent[s]). Age (OR = 1.1), gender (OR = 1.7; girls as references), near work time (OR = 1.2), and both maternal (OR, 1.4 and 2.0 for moderate and high myopia) and paternal myopia (OR, 1.6 and 1.9 for moderate and high myopia) were independent risk factors for lacking hyperopia reserve.
Conclusion: Severe parental myopia was associated with a lower SER, longer AL, and higher AL/CR ratio in preschool children. Parental myopia and near work may predispose children to faster elimination of hyperopia reserves before exposure to higher educational stress.

Introduction: Anterior ischemic optic neuropathy (AION) can mimic glaucoma and consequently cause difficulties in differential diagnosis. The purpose of this paper was to summarize differences in diagnostic tests that can help perform a correct diagnosis.
Methods: The search strategy was performed according to the PRISMA 2009 guidelines, and four databases were used: MEDLINE, Embase, Web of Science, and Cochrane. Totally, 772 references were eligible; 39 were included after screening with respect to inclusion criteria that included English language and published in the 20 years before search date.
Results: Ninety percent (n = 35) of included studies used optical coherence tomography (OCT). Glaucomatous eyes had a significantly greater cup area, volume and depth, cup-to-disk ratio, a lower rim volume and area, and a thinner Bruch's membrane opening-minimum rim width. Retinal nerve fiber layer (RNFL) thinning in glaucomatous eyes occurred primarily at the superotemporal, inferotemporal, and inferonasal sectors, while AION eyes demonstrated mostly superonasal thinning. Glaucoma eyes showed greater macular ganglion cell layer thickness, except at the inferotemporal sector. OCT angiography measurements demonstrated a significant decrease in superficial and deep macular vessel density (VD) in glaucoma compared to AION with similar degree of visual field damage; the parapapillary choroidal VD was spared in AION eyes compared to glaucomatous eyes.
Conclusion: By use of OCT imaging, optic nerve head parameters seem most informative to distinguish between glaucoma and AION. Although both diseases affect the RNFL thickness, it seems to do so in different sectors. Differences in structure and vascularity of the macula can also help in making the differential diagnosis.

Background: Although the p.C759F (c.2276G>T, p.Cys759Phe) variant in the USH2A gene has been identified in association with retinal degeneration by several authors, its pathogenicity has been questioned once by the publication of two unaffected homozygotes from a single family.
Objectives: The objective of the study was to ascertain the role of p.C759F in hereditary retinal disease.
Methods: We examined 87 research articles reporting on patients carrying this variant and then used this information as primary data for a series of meta-analytical tests.
Results: Independent statistical analyses showed that p.C759F (i) is highly enriched in patients with respect to healthy individuals, (ii) represents a clear-cut recessive allele causing disease when it is in trans with other mutations, (iii) is pathogenic in homozygotes.
Conclusions: Our results confirm that p.C759F is a bona fide mutation, leading to retinal blindness according to a recessive pattern of inheritance.

Introduction: The aim of the study was to examine alterations in visual acuity in patients with diabetic macular edema (DME), classified according to the TCED-HFV optical coherence tomography (OCT) system, following anti-vascular epithelial growth factor (VEGF) therapy.
Methods: The medical records of patients with DME receiving anti-VEGF therapy were retrospectively reviewed. Patients were divided into four groups according to the TCED-HFV OCT classification. Patient demographic and clinical characteristics and best-corrected visual acuity (BCVA) before and after treatment were compared among the groups.
Results: The BCVA before treatment was 0.49 ± 0.18, 0.81 ± 0.41, 0.83 ± 0.41, and 0.82 ± 0.49 in the early DME, advanced DME, severe DME, and atrophic maculopathy groups, respectively. The BCVA in the early DME group was therefore significantly lower than that in the other three groups (p = 0.042). After treatment, the BCVA improved to 0.15 ± 0.17, 0.52 ± 0.31, 0.62 ± 0.32, and 0.69 ± 0.47 in the early DME, advanced DME, severe DME, and atrophic maculopathy groups, respectively (p < 0.005). There were some differences among patients in the four groups in terms of the duration of diabetes, percentage of hemoglobin A1c, and duration of hypertension.
Conclusion: The TCED-HFV OCT classification of patients with DME is exact and functional and can allow the severity of DME, and its response to anti-VEGF therapy, to be estimated.

Introduction: This study aimed to investigate changes in retinal microvascular morphology and associated factors, and their relationship with diabetic retinopathy (DR) in children with type 1 diabetes mellitus (T1DM).
Methods: Thirty-eight children enrolled in this 3-year follow-up study underwent complete ophthalmic examinations including fundus photography. Retinal vascular parameters were measured automatically and compared between baseline and follow-up. Multiple linear regression was used to investigate factors affecting changes in vascular parameters. Binary logistic regression was used to analyze the relationship between retinal microvascular morphology and DR.
Results: The caliber of all retinal vessels (within 1-1.5 papillary diameter [PD] from the center of the optic disc, p = 0.030; 1.5-2 PD, p = 0.003), arterioles, and venules (1.5-2 PD, p = 0.001) was narrower in nearly all regions in the follow-up group compared with the baseline group. Vascular tortuosity increased in the central part of the retina and decreased in the periphery. The density (1-1.5 PD, p = 0.030) and fractal dimension (p = 0.037) of retinal vessels were increased at the end of the follow-up compared with baseline. Retinal vascular caliber was independently correlated with DR (odds ratio 0.793 [95% confidence interval 0.633-0.993]; p = 0.044).
Conclusion: Retinal microvascular morphology in children with T1DM varied with the disease course. Narrower retinal vessels may be an independent risk factor for DR. Results of this study emphasized the importance of regular follow-up of fundus vascular morphology for the detection of early DR in children with T1DM.

Introduction: Handheld retinal imaging cameras are relatively inexpensive and highly portable devices that have the potential to significantly expand diabetic retinopathy (DR) screening, allowing a much broader population to be evaluated. However, it is essential to evaluate if these devices can accurately identify vision-threatening macular diseases if DR screening programs will rely on these instruments. Thus, the purpose of this study was to evaluate the detection of diabetic macular pathology using monoscopic macula-centered images using mydriatic handheld retinal imaging compared with spectral domain optical coherence tomography (SDOCT).
Methods: Mydriatic 40°-60° macula-centered images taken with 3 handheld retinal imaging devices (Aurora [AU], SmartScope [SS], RetinaVue 700 [RV]) were compared with the Cirrus 6000 SDOCT taken during the same visit. Images were evaluated for the presence of diabetic macular edema (DME) on monoscopic fundus photographs adapted from Early Treatment Diabetic Retinopathy Study (ETDRS) definitions (no DME, noncenter-involved DME [non-ciDME], and center-involved DME [ciDME]). Sensitivity, specificity, positive predictive value, and negative predictive value were calculated for each device with SDOCT as gold standard.
Results: Severity by ETDRS photos: no DR 33.3%, mild NPDR 20.4%, moderate 14.2%, severe 11.6%, proliferative 20.4%, and ungradable for DR 0%; no DME 83.1%, non-ciDME 4.9%, ciDME 12.0%, and ungradable for DME 0%. Gradable images by SDOCT (N = 217, 96.4%) showed no DME in 75.6%, non-ciDME in 9.8%, and ciDME in 11.1%. The ungradable rate for images (poor visualization in >50% of the macula) was AU: 0.9%, SS: 4.4%, and RV: 6.2%. For DME, sensitivity and specificity were similar across devices (0.5-0.64, 0.93-0.97). For nondiabetic macular pathology (ERM, pigment epithelial detachment, traction retinal detachment) across all devices, sensitivity was low to moderate (0.2-0.5) but highly specific (0.93-1.00).
Conclusions: Compared to SDOCT, handheld macular imaging attained high specificity but low sensitivity in identifying macular pathology. This suggests the importance of SDOCT evaluation for patients suspected to have DME on fundus photography, leading to more appropriate referral refinement.

Introduction: To investigate the characteristics of macular pseudoholes (MPHs) with different foveal profiles and their impact on preoperative and postoperative visual acuity (VA).
Methods: A retrospective review of 47 eyes from 46 consecutive patients with MPH who had undergone vitrectomy was conducted. The MPHs were classified into u-shape and v-shape according to the morphological description of the foveola base. The best-corrected visual acuity (BCVA), central foveal point thickness, parafoveal thickness, parafoveal inner and outer retinal thickness, stretched lamellar cleavage, microcystic macular edema (MME), disorganization of retinal inner layers (DRIL), and the integrity of outer retinal layers were recorded.
Results: The eyes in the v-shaped group (n = 31) had lower BCVA, thicker retinal thickness, more intraretinal cleavage, MME, and DRIL than the u-shaped (n = 16) group (all p < 0.05). Multiple regression analysis revealed that the morphology of the foveola base was significantly related to the preoperative BCVA (p = 0.025). The VA was significantly improved in both groups, and the improvement was greater in the v-shaped group (p = 0.024). No significant difference was found in the postoperative BCVA between the two groups (all p > 0.05).
Conclusion: The v-shape, reflecting the stretch in the foveola, had a significant impact on preoperative BCVA. However, the VA was improved after surgery whatever their initial foveal profile.

Introduction: Due to its progressive nature, early evaluation and timely prediction of legal blindness are important in patients with neovascular age-related macular degeneration (nAMD). We examined the association between early-stage variation in central retinal thickness (CRT) and long-term visual outcomes in patients with nAMD.
Methods: We included 103 nAMD patients who were administered anti-vascular endothelial growth factor (anti-VEGF). Participants were considered qualified if they were (1) 50 years and older, (2) treatment-naïve, (3) received standard anti-VEGF treatment and had complete baseline information. We further excluded patients with less than 1-year follow-up data and those who experienced best corrected visual acuity ≤35. Early-stage variability in CRT was measured as the first-year coefficient of variability (CV) of CRT. Patients were then classified into the high-variability and low-variability groups according to the X-tile. A product-limit plot was used to demonstrate the differences and tested with the log-rank test. The association between first-year variability and visual outcomes was quantified using Cox regression models. Time-to-event primary endpoint was the overall visual preservation (OVP) rate, defined as the time from the first injection to legal blindness, i.e., best corrected visual acuity ≤35 Early Treatment Diabetic Retinopathy Study (ETDRS) letters.
Results: A threshold of 20% of first-year CV in CRT was used to categorize 76 qualified patients into high variability (35, 46.1%) and low variability (41, 53.9%). The 5- and 10-year OVPs for patients with high versus low variability were 76% versus 48% and 59% versus 22%, respectively. High early-stage CRT variability showed a significantly higher risk of legal blindness. Even after adjusting for the demographic and clinical features, the variability remained significant (HR = 2.39, 95% CI: 1.20-4.78).
Conclusion: First-year variability of CRT was predictive of long-term visual outcomes in patients with nAMD, and 20% of the variability could be used as a clinically convenient threshold to qualitatively classify patients into high- and low-variability groups. The current study is important for identifying high-risk populations and for long-term disease management.

Introduction: The aims of this study were to investigate the molecular alterations of cuproptosis-related genes and to construct the cuproptosis-related circular RNA (circRNA)-microRNA (miRNA)-mRNA networks in neovascular age-related macular degeneration (nAMD).
Methods: The transcriptional profiles of laser-induced choroid neovascularization (CNV) mouse models and nAMD patient samples were obtained from sequencing and from the GEO database (GSE146887), respectively. The expression levels of ten cuproptosis-related genes (FDX1, DLAT, LIAS, DLD, PDHB, MTF1, CDKN2A, GLS, LIPT1, and PDHA1) were extracted and verified in both mouse CNV models and patient peripheral blood mononuclear cells (PBMCs) samples. The cuproptosis-related circRNA-miRNA-mRNA network was further constructed based on miRNet database, the dataset GSE131646 of small RNA expression profile, and the dataset GSE140178 of circRNA expression profile in mouse CNV models.
Results: The significant upregulation of Cdkn2a and Mtf1 and the downregulation of other 5 cuproptosis-related genes were verified in the mouse CNV model, but only CDKN2A significantly upregulated in PBMCs of patients with nAMD. Four miRNAs were detected in the intersection between miRNet prediction and sequencing data: miR-129-5p, miR-129-2-3p, miR-182-5p, and miR-615-3p. There were 9 circRNAs at the intersection of hsa-miR-182-5p and hsa-miR-615-3p predictions, one circRNA predicted by hsa-miR-129-5p and GSE140178 (hsa-circASH1L), and one circRNA predicted by hsa-miR-182-5p and hsa-miR-615-3p (hsa-circNPEPPS).
Conclusion: This study suggested the repression of cuproptosis in nAMD pathologies and constructed a cuproptosis-related network of 8 cuproptosis-related genes, 4 miRNAs, and 11 circRNAs.
