IF 4.4 Q1 OPHTHALMOLOGY Pub Date : 2024-10-01 DOI: 10.1016/j.oret.2024.04.014

Purpose

To evaluate the 3-year outcomes of VEGF inhibitors in the treatment of cystoid macular edema due to branch retinal vein occlusion (BRVO) in an international multicenter cohort of eyes.

Design

Multicenter, international, BRVO database study.

Subjects

Seven hundred forty-seven patients (760 eyes) undergoing intravitreal therapy for BRVO for 3 years in a multicenter international setting.

Methods

Demographics, visual acuity (VA) in logarithm of the minimum angle of resolution letters, central subfield thickness (CST), treatments, number of injections, and visits data was collected using a validated web-based tool.

Main Outcome Measures

Visual acuity gain at 3 years in logarithm of the minimum angle of resolution letters. Secondary outcome measures included anatomical results, treatment pattern, and percentage of completers. A subgroup analysis by study drug was conducted for clinical outcomes.

Results

Mean adjusted VA change was +11 letters (95% confidence interval 9–13), mean adjusted change in CST was −176 μm (−193, −159). Median number of injections/visits was 16 of 24 at 3 years of follow-up. Most eyes received VEGF inhibitors exclusively (89%, n = 677) and as a monotherapy in 71% (n = 538). Few eyes were switched to steroids (11%, n = 83). Suspensions in treatment >180 days occurred in 26% of study eyes. Aflibercept showed greater CST reductions (−147 vs. −128 vs. −114 μm; P < 0.001) and significantly lower switching rates (14% vs. 38% vs. 33%; P < 0.001) compared with ranibizumab and bevacizumab, respectively.

Conclusions

This international study of 3-year BRVO outcomes after starting treatment with VEGF inhibitors found adequate visual and anatomical results in routine clinical care. Visual outcomes were similar among the different initiating VEGF inhibitors, although eyes starting with aflibercept had better anatomical outcomes and a lower switching rate.

Imaging Characteristics and Clinical Utility of Half-Dose versus Full-Dose Ultrawidefield Fundus Fluorescein Angiography 半剂量与全剂量超宽视场荧光素血管造影的成像特点和临床实用性。
IF 4.4 Q1 OPHTHALMOLOGY Pub Date : 2024-10-01 DOI: 10.1016/j.oret.2024.04.024

Purpose

In early 2022, a fluorescein shortage occurred in the United States. To meet the standard of care for patients who required ultrawidefield fundus fluorescein angiography (UWFFA), a regimen of half-dose (250 mg) sodium fluorescein (10%) was adopted instead of the full dose (500 mg) at the Cole Eye Institute (CEI). In this paper, we compare the image quality, clinical utility, and the side-effect profile of half-dose versus full-dose fluorescein in UWFFA for a cohort of stable patients.

Design

Retrospective chart review.

Participants

Patients with retinal vascular disease were included if they received half-dose and full-dose UWFFA (Optos California) within 6 months at the CEI. Eyes were excluded if they received intraocular injections, laser procedures, new immunosuppression, and worsened or improved inflammation on clinical examination.

Methods

Quantitative assessment of vascular leakage was performed using a machine learning-enhanced automated segmentation platform. Leakage from late-phase UWFFA images was compared between half-dose and full-dose images. Qualitative assessment of image quality and relative vascular leakage was performed by 2 masked independent reviewers. Side effects after fluorescein administration were recorded for each patient.

Main Outcome Measures

Masked leakage grading and automated leakage scores.

Results

There were 52 eyes of 35 patients, 42 (81%) uveitic, 5 (9%) diabetic, and 4 (8%) normal controls. Patients had no change to their visual acuity (logarithm of the minimum angle of resolution mean, 0.3 ± 0.6), anterior chamber and vitreous cell between UFFWA’s. UWFFA images were deemed of equal quality and leakage by both masked reviewers (78%–87% agreement; κ, 0.642). Automated leakage analysis showed mildly increased leakage in half-dose images overall (3.8% vs. 2.8%; P = 0.01) and in the macula (1.5% vs. 0.6%; P = 0.01). Side effects included nausea (half [n = 3, 9%] vs. full [n = 2, 6%]; P = 0.69) and urticaria (n = 0, 0% vs. n = 1, 2%; P = 0.99) and were not different between doses.

Conclusions

In this cohort, half-dose UWFFA produced images that were of similar quality, clinical utility and with a similar side effect profile compared with full dose. Half-dose UWFFA can be used to accurately assess the retinal vasculature and could be used primarily as a method to save cost and prevent waste.

目的:2022 年初,美国出现荧光素短缺。为了满足超宽眼底荧光素血管造影(UWFFA)患者的治疗标准,科尔眼科研究所(CEI)采用了半剂量(250 毫克)荧光素钠(10%)替代全剂量(500 毫克)的治疗方案。在本文中,我们比较了半剂量与全剂量荧光素在 UWFFA 中的成像质量、临床实用性和副作用情况:对象、参与者和/或对照组:视网膜血管疾病患者如果在 CEI 的 6 个月内接受过半剂量和全剂量 UWFFA(Optos California,Dunfermline,UK)治疗,则纳入研究对象。方法、干预或测试:使用机器学习增强型自动分割平台对血管渗漏进行定量评估。比较了半剂量和全剂量 UWFFA 晚期图像的渗漏情况。图像质量和相对血管渗漏的定性评估由两名蒙面独立审稿人完成。记录每位患者使用荧光素后的副作用:结果:结果:35 名患者的 52 只眼睛中,42 只(81%)患有葡萄膜炎,5 只(9%)患有糖尿病,4 只(8%)为正常对照组。患者的视力(LogMAR 平均值为 0.3±0.6)、前房和玻璃体细胞在两次 UFFWA 之间没有变化。两位蒙面审查员认为 UWFFA 图像的质量和渗漏情况相同(一致性为 78-87%,kappa 0.642)。自动渗漏分析显示,半剂量图像总体渗漏轻度增加(3.8% vs 2.8%,p=0.01),黄斑渗漏增加(1.5% vs 0.6%,p=0.01)。副作用包括恶心(半剂量(n=3,9%) vs 全剂量(n=2,6%),p=0.69)和荨麻疹(n=0,0% vs n=1,2%,p=0.99),不同剂量之间没有差异:结论:在这组人群中,半剂量 UWFFA 与全剂量相比,所产生的图像质量、临床实用性和副作用相似。半剂量 UWFFA 可用来准确评估视网膜血管,可主要用作节约成本和防止浪费的方法。

Comparative Effectiveness of Glucagon-Like Peptide-1 Receptor Agonists, Sodium-Glucose Cotransporter 2 Inhibitors, Dipeptidyl Peptidase-4 Inhibitors, and Sulfonylureas for Sight-Threatening Diabetic Retinopathy GLP-1 受体激动剂、SGLT2 抑制剂、DPP-4 抑制剂和磺脲类药物治疗视力危急型糖尿病视网膜病变的疗效比较。
IF 4.4 Q1 OPHTHALMOLOGY Pub Date : 2024-10-01 DOI: 10.1016/j.oret.2024.05.003

Objective

To investigate whether the choice of glucose-lowering agent for type 2 diabetes (T2D) impacts a patient’s risk of developing sight-threatening diabetic retinopathy complications.

Design

Retrospective observational database study emulating an idealized target trial.

Subjects

Adult (≥21 years) enrollees in United States commercial, Medicare Advantage, and Medicare fee-for-service plans from January 1, 2014, to December 31, 2021, with T2D and moderate cardiovascular disease (CVD) risk who had no baseline history of advanced diabetic retinal complications, initiating treatment with glucagon-like peptide-1 receptor agonists (GLP-1 RA), sodium-glucose cotransporter 2 inhibitors (SGLT2i), dipeptidyl peptidase-4 inhibitors (DPP-4i), and sulfonylureas.

Methods

We used inverse propensity scoring weights in time-to-event Cox proportional hazards models.

Main Outcome Measures

Treatment for either diabetic macular edema or proliferative diabetic retinopathy.

Results

The final study population included 371 698 patients, of whom 42 265 initiated GLP-1 RA, 53 476 initiated SGLT2i, 78 444 initiated DPP-4i, and 197 513 initiated sulfonylurea agents. The probability of treatment for sight-threatening retinopathy within 2 and 5 years was 0.3% and 0.7% for patients initiating SGLT2i (median follow-up 830 [interquartile range (IQR), 343–1401] days), 0.4% and 1.0% for GLP-1 RA (669 [IQR, 256–1167] days), 0.4% and 0.9% for DPP-4i (1263 [IQR, 688–1938] days), and 0.5% and 1.2% for sulfonylurea (1223 [IQR, 662–1879] days). Sodium-glucose cotransporter 2 inhibitors use was associated with a lower risk of treatment for sight-threatening retinopathy compared with all other medication classes, including GLP-1 RA (hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.55–0.97), DPP-4i (HR, 0.79; 95% CI, 0.64–0.97), and sulfonylurea (HR, 0.61; 95% CI, 0.50–0.74). Glucagon-like peptide-1 receptor agonists use was associated with a similar risk of sight-threatening retinopathy as DPP-4i (HR, 1.07; 95% CI, 0.85–1.35) and sulfonylurea (HR, 0.83; 95% CI, 0.67–1.03).

Conclusions

Sodium-glucose cotransporter 2 inhibitors use was associated with a lower risk of sight-threatening diabetic retinopathy among adults with T2D and moderate CVD risk compared with other glucose-lowering therapies. Glucagon-like peptide-1 receptor agonists do not confer increased retinal risk, relative to DPP-4i and sulfonylurea medications.

Isolated Retinal Neovascularization in Retinopathy of Prematurity 早产儿视网膜病变中的孤立视网膜新生血管:临床关联和预后影响。
IF 4.4 Q1 OPHTHALMOLOGY Pub Date : 2024-10-01 DOI: 10.1016/j.oret.2024.04.025

Objective

Isolated retinal neovascularization (IRNV) is a common finding in patients with stage 2 and 3 retinopathy of prematurity (ROP). This study aimed to further classify the clinical course and significance of these lesions (previously described as “popcorn” based on clinical appearance) in patients with ROP as visualized with ultrawidefield OCT (UWF-OCT).

Design

Single center, retrospective case series.

Participants

Images were collected from 136 babies in the Oregon Health and Science University neonatal intensive care unit.

Methods

A prototype UWF-OCT device captured en face scans (>140°), which were reviewed for the presence of IRNV along with standard zone, stage, and plus classification. In a cross-sectional analysis we compared demographics and the clinical course of eyes with and without IRNV. Longitudinally, we compared ROP severity using a clinician-assigned vascular severity score (VSS) and compared the risk of progression among eyes with and without IRNV using multivariable logistic regression.

Main Outcome Measures

Differences in clinical demographics and disease progression between patients with and without IRNV.

Results

Of the 136 patients, 60 developed stage 2 or worse ROP during their disease course, 22 of whom had IRNV visualized on UWF-OCT (37%). On average, patients with IRNV had lower birth weights (BWs) (660.1 vs. 916.8 g, P = 0.001), gestational age (GA) (24.9 vs. 26.1 weeks, P = 0.01), and were more likely to present with ROP in zone I (63.4% vs. 15.8%, P < 0.001). They were also more likely to progress to stage 3 (68.2% vs. 13.2%, P < 0.001) and receive treatment (54.5% vs. 15.8%, P = 0.002). Eyes with IRNV had a higher peak VSS (5.61 vs. 3.73, P < 0.001) and averaged a higher VSS throughout their disease course. On multivariable logistic regression, IRNV was independently associated with progression to stage 3 (P = 0.02) and requiring treatment (P = 0.03), controlling for GA, BW, and initial zone 1 disease.

Conclusions

In this single center study, we found that IRNV occurs in higher risk babies and was an independent risk factor for ROP progression and treatment. These findings may have implications for OCT-based ROP classifications in the future.

目的:孤立性视网膜新生血管(IRNV)是早产儿视网膜病变(ROP)2 期和 3 期患者的常见病变。本研究旨在通过超宽视场光学相干断层扫描(UWF-OCT)对早产儿视网膜病变患者的这些病变(以前根据临床表现描述为 "爆米花")的临床过程和意义进行进一步分类:设计:单中心、回顾性病例系列:收集了俄勒冈健康与科学大学新生儿重症监护室 136 名婴儿的图像:UWF-OCT原型设备采集全脸扫描(>140°),根据标准区域、分期和加号分类检查是否存在IRNV。在横向分析中,我们比较了有 IRNV 和无 IRNV 眼睛的人口统计学特征和临床过程。纵向分析中,我们使用临床医生指定的血管严重程度评分(VSS)比较了ROP的严重程度,并使用多变量逻辑回归(MLR)比较了有IRNV和无IRNV眼球的病情进展风险:结果:136 名患者中,有 60 名患者发展到了第 3 期:在 136 例患者中,有 60 例在病程中发展为 2 期或更严重的 ROP,其中 22 例在 UWF-OCT 中观察到 IRNV(37%)。平均而言,IRNV 患者的出生体重(BW)(660.1 克 vs 916.8 克,P = 0.001)和胎龄(GA)(24.9 周 vs 26.1 周,P = 0.01)较低,更有可能在 I 区出现 ROP(63.4% vs 15.8%,P < 0.001)。他们也更有可能发展到第三阶段(68.2% 对 13.2%,p < 0.001)和接受治疗(54.5% 对 15.8%,p = 0.002)。IRNV患者的VSS峰值更高(5.61 vs 3.73,p < 0.001),整个病程中的平均VSS值也更高。在MLR中,IRNV与病情进展到3期(p = 0.02)和需要治疗(p = 0.03)独立相关,并控制了GA、BW和最初的1区疾病:在这项单中心研究中,我们发现 IRNV 发生在风险较高的婴儿中,是导致 ROP 进展和治疗的独立风险因素。这些发现可能会对未来基于 OCT 的 ROP 分类产生影响。

Clinical Implications of Alternating Hypointense Bands on OCT Angiography in Retinal Vascular Occlusive Disease 视网膜血管闭塞症患者 OCT 血管造影上的交替低密度带的临床意义。
IF 4.4 Q1 OPHTHALMOLOGY Pub Date : 2024-10-01 DOI: 10.1016/j.oret.2024.04.022

Purpose

To demonstrate the relationship between alternating hypointense signal bands on OCT angiography (OCTA), real-time fluorescein angiography (FA), and structural OCT findings in patients with retinal vascular occlusive disease (RVOD).

Design

Retrospective, consecutive case series.

Subjects

Consecutive patients with a clinical diagnosis of acute RVOD and alternating bands of hypointense OCTA flow signal on en face projections.

Methods

Complete ophthalmic examination and multimodal imaging, including color fundus photography, real-time FA, spectral-domain OCT, and OCTA performed with different instruments having different scan speeds and acquisition protocols.

Main Outcome Measures

The primary outcomes were: hypointense OCTA band characteristics (number, width, orientation, and location), OCTA acquisition characteristics (speed and scan direction), and FA findings including delayed arteriovenous (AV) transit and pulsatile flow. Secondary outcomes were: structural OCT changes including retinal fluid, paracentral acute middle maculopathy (PAMM) lesion, and a prominent middle limiting membrane (p-MLM) sign.

Results

OCT angiography hypointense bands were detected in the superficial and deep vascular plexuses in 9 eyes of 9 patients with either partial central retinal vein occlusion (RVO) or nonischemic RVO. When obtained on the same device, hypointense bands were thinner and more numerous at lower (100 kHz) scan speeds compared with higher (200 kHz) scan speeds. Band orientation was parallel to the OCTA scan direction, and their extent correlated with the area of delayed AV transit on FA. Structural OCT showed multiple PAMM lesions in 78% of cases and a p-MLM sign centered in the fovea in 44% of cases.

Conclusions

OCT hypointense bands are a novel biomarker in RVOD indicating delayed AV transit and pulsatile filling without the need for dye angiography. Structural OCT often shows PAMM in these eyes and, less commonly, a p-MLM sign.
