To describe a largely unrecognized feature in pathologic myopia, namely, perivascular patchy chorioretinal atrophy (PVCA).
DESIGN
Cross-sectional study.
METHODS
A total of 604 eyes of 312 highly myopic patients followed at Strasbourg University Hospitals were reviewed for the presence of PVCA lesions. Demographic, clinical, and paraclinical data (ultra-widefield retinography, optical coherence tomography [OCT], fluorescein and indocyanine green angiography images) were analyzed. Controls were matched for age, sex, and axial length (AL).
RESULTS
A total of 47 eyes (7.8%) of 32 patients presented with 88 PVCA lesions in total. Mean age was 65.9 ± 10.2 years, and mean best corrected visual acuity (BVCA) was 0.86 ± 0.76 logMAR. All patients had posterior staphyloma, with PVCA localized within the staphyloma (58%), on its margins (39%), or outside of it (3%). Atrophic lesions were mainly located in the temporal retina (71%) and on the first- or second-order branches of the central retinal vessels (95%). OCT scans revealed an anterior scleral protrusion in 74% of cases, with an average height of 319 ± 152 µm. PVCA patients had longer AL (32.94 ± 1.87 mm vs 29.96 ± 2.79 mm; P < .01) than non-PVCA patients. When compared to matched controls, PVCA patients had lower BCVA (0.86 ± 0.76 logMAR vs 0.59 ± 0.71 logMAR; P = .01) and reduced macular choroidal thickness (38 ± 31 µm vs 54 ± 38 µm; P = .02).
CONCLUSION
PVCA is a newly described feature of pathological myopia associated with reduced visual acuity. Its association with anterior scleral protrusion suggests that scleral curvature change may represent a specific cause leading to chorioretinal atrophy.

PURPOSE
To compare the risk of renal adverse events, particularly acute kidney injury (AKI), between intravitreal anti–vascular endothelial growth factor (anti-VEGF) agents.
DESIGN
Meta-analysis.
METHODS
A systematic literature search was conducted on Ovid Medline, Embase, and the Cochrane Library for randomized controlled trials (RCTs) published from January 2005 to February 2024 involving adult patients receiving anti-VEGF intravitreal injections for age-related macular degeneration, diabetic macular edema, and macular edema secondary to retinal vein occlusion. The primary outcome was the comparative risk of AKI between anti-VEGF agents and sham injections. Secondary outcomes involved other renal adverse events. Subgroup analyses were conducted by specific disease indications. A random-effects model was used for meta-analysis to estimate risk ratios (RRs) and their 95% confidence intervals, with a P value of <.05 representing statistical significance. Risk of bias was assessed using the Cochrane Risk of Bias 2 (ROB2) tool, and the certainty of evidence was evaluated through the Cochrane Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework.
RESULTS
A total of 10,031 eyes from 11 RCTs were included. No significant differences were found in the risk of acute or chronic renal conditions, obstructive uropathies, neoplasia, or infectious processes between anti-VEGF agents and sham therapy. AKI was reported in 5.4% (n = 10/185) of patients treated with bevacizumab, 1.3% (n = 6/456) with sham, 1.0% (n = 48/4724) with aflibercept, 0.8% (n = 15/1929) with faricimab, 0.5% (n = 5/1098) with brolucizumab, and 0.3% (n = 5/1639) with ranibizumab. No significant differences in AKI risk were observed between any of the anti-VEGF agents and sham (P > .05 for all comparisons). However, there was an increased risk of patient-reported symptoms with 1.25 mg bevacizumab compared to 2 mg aflibercept (RR = 3.26, 95% CI = 1.07-9.93, P = .04), driven primarily by reports of hematuria: 4.3% (bevacizumab), 0.7% (sham), 0.2% (aflibercept), 0.1% (faricimab), and 0.1% (ranibizumab).
CONCLUSIONS
US Food and Drug Administration (FDA)–approved intravitreal anti-VEGF agents do not significantly increase the risk of AKI compared to sham injections. Nevertheless, variations in patient-reported renal symptoms were observed across different anti-VEGF drugs. These variations were influenced primarily by differences in hematuria events, which may be a result of differential systemic absorption by these agents. These results underscore the importance of continuous monitoring and pharmacovigilance.

Purpose
The integration of generative artificial intelligence (GAI) into scientific research and academic writing has generated considerable controversy. Currently, standards for using GAI in academic medicine remain undefined. This study aims to conduct a comprehensive analysis of the guidance provided for authors regarding the use of GAI in ophthalmology scientific journals.
Design
Cross-sectional bibliometric analysis.
Participants
A total of 140 ophthalmology journals listed in the Scimago Journal and Country Rankings, regardless of language or origin.
Methods
We systematically searched and screened the 140 ophthalmology journals’ websites on October 19 and 20, 2024, and conducted updates on November 19 and 20, 2024.
Main Outcome Measures
The content of GAI guidelines from the websites of the 140 ophthalmology journals.
Results
Of 140 journals reviewed, 96 (69%) provide explicit guidelines for authors regarding the use of GAI. Among these, nearly all journals agree on 3 key points: (1) 94 journals (98%) have established specific guidelines prohibiting GAI from being listed as an author; (2) 94 journals (98%) emphasize that human authors are responsible for the outputs generated by GAI tools; and (3) all 96 journals require authors to disclose any use of GAI. In addition, 20 journals (21%) specify that their guidelines pertain solely to the writing process with GAI. Furthermore, 92 journals (66%) have developed guidelines concerning GAI-generated images, with 63 journals (68%) permitting their use and 29 (32%) prohibiting them. Among those that prohibit GAI images, 27 journals (93%) allow their use under specific conditions.
Conclusion
Although there is considerable ethical consensus among ophthalmology journals regarding the use of GAI, notable variations exist in terms of permissible use and disclosure practices. Establishing standardized guidelines is essential to safeguard the originality and integrity of scientific research. Researchers must uphold high standards of academic ethics and integrity when using GAI.

Purpose
To analyze the influence of individual parameters on the postoperative refractive outcomes of small incision lenticule extraction (SMILE) in myopic eyes using machine learning.
Design
Retrospective Clinical Cohort Study
Methods
This study included 477 patients (922 eyes) of SMILE and divided them into two groups based on postoperative spherical equivalent (SE) ≤ -0.50D to analyze the factors influencing postoperative refractive outcomes. The XGBoost model took 72 clinical parameters (34 biomechanical, 31 morphological, 4 surgical-related, and 3 preoperative refractive parameters) as features; randomly selected 42 eyes from the good refractive outcomes group and all eyes (a total of 42 eyes) from the poor refractive outcomes group to conduct 100 times influence factors analysis.
Results
The 10 most important factors influencing postoperative refractive outcomes included 3 surgery-related parameters (PTA, LTmax, and RST), 3 corneal biomechanical parameters (HC Time, Deflection Amp Max (ms), and SSI), 2 corneal morphological parameters (R Per F and Rs F), and 2 preoperative refractive parameters (SE and SD). When PTA ≥ 25.09%, LTmax ≥ 139μm, SE ≤ −7.00D, or SD ≤ −6.75D, the postoperative SE significantly increased (all P < 0.05), with averages of −0.183D, −0.171D, −0.188D, and −0.184D. After controlling for age, intraocular pressure, and corneal thickness, the postoperative SE significantly increased when HC time ≥ 17.422 and Deflection Amp Max (ms) ≥ 16.616, reaching −0.209D and −0.202D.
Conclusions
More corneal tissue ablation, longer HC Time and Deflection Amp Max (ms), lower SSI, and higher preoperative refractive error may result in poor postoperative refractive outcomes.
目的:利用机器学习方法分析个体参数对近视眼小切口人工晶体摘除术术后屈光疗效的影响:方法:纳入天津市眼科医院477例(922眼)小切口皮瓣摘除术患者,以术后球面等值(SE)≤-0.50D为指标,将患者分为两组,分析影响术后屈光疗效的因素。XGBoost 模型共包含 72 个参数,包括 34 个生物力学参数、31 个形态学参数、4 个手术相关参数和 3 个临床获得的术前屈光参数。XGBoost 模型从屈光疗效好的一组中随机抽取 42 名患者(即屈光疗效差的一组患者人数),进行 100 个影响因素分析。采用 Kolmogorov-Smirnov 检验对数据进行正态性检验,采用独立样本 t 检验或 Mann-Whitney U 检验比较组间差异;采用 Spearman 相关性分析方法分析各因素与术后 SE 的相关性:922只眼睛的术前SE和术后SE平均值分别为-5.01±1.48 D和-0.06±0.18 D。影响术后屈光结果的 10 个最重要因素包括角膜生物力学参数(最高凹[HC]时间、最大偏转振幅时间[Deflection Amp Max (ms)]和应力应变指数[SSI])、手术相关参数(消融厚度百分比[PTA]、最大皮孔厚度[LTmax]和残余基质厚度[RST])、角膜形态参数(角膜前表面半径和陡半径)和术前屈光参数(SE 和球面屈光度[SD])。当 PTA ≥ 25.09%、LTmax ≥ 139 μm、SE ≤ -7.00 D 或 SD ≤ -6.75 D 时,术后 SE 显著增加(所有 PConclusions:过多的组织切削、更长的HC时间、最大偏转电流(ms)、更低的SSI以及术前屈光力过高都会恶化术后屈光结果。适当调整提名图可以改善结果。
