Purpose

This study aimed to assess the risk of ocular adverse events, including retinal artery occlusion (RAO), retinal vein occlusion (RVO), noninfectious uveitis (NIU), noninfectious scleritis (NIS), optic neuritis (ON), ischemic optic neuropathy (ION), and ocular motor cranial nerve palsy (OMCNP), after coronavirus disease 2019 (COVID-19) infection.

Design

Population-based self-controlled case series (SCCS).

Participants

The study included patients from the entire Korean population of 52 million who experienced incident RAO, RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, or OMCNP between January 1, 2021, and October 29, 2022.

Methods

This nationwide SCCS utilized data from the Korea National Health Insurance Service and the Korea Disease Control and Prevention Agency. The risk period after infection was defined as up to 24 weeks after COVID-19 infection. Conditional Poisson regression was used to calculate the relative incidence rate ratios (IRRs) for RAO, RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, and OMCNP during the designated risk periods.

Main Outcome Measures

The IRRs for RAO, RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, and OMCNP during the risk periods.

Results

The study included 9336, 103 362, 201 010, 25 428, 23 744, 3026, 69 933, and 16 335 cases of incident RAO, RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, and OMCNP, respectively. The IRRs (95% confidence interval) during the early risk period (1–8 weeks) were 0.94 (0.83–1.07), 1.01 (0.97–1.04), 1.00 (0.98–1.03), 0.96 (0.90–1.03), 1.00 (0.94–1.07), 0.97 (0.81–1.17), 0.97 (0.93–1.01), and 1.02 (0.94–1.11), respectively. In the late risk period (9–24 weeks), the IRRs were 1.02 (0.92–1.12), 1.01 (0.98–1.04), 1.01 (0.99–1.03), 1.02 (0.97–1.08), 1.02 (0.97–1.08), 0.99 (0.85–1.15), 1.02 (0.99–1.06), and 0.97 (0.90–1.03), respectively. Stratified analyses showed that in patients with a history of cerebro-cardiovascular disease, the risk of RAO increased during the late risk period, with an IRR (95% confidence interval) of 1.19 (1.02–1.40).

Conclusions

The risk of incident RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, or OMCNP did not increase after COVID-19 infection. The risk of incident RAO increased only in individuals with preexisting cardio-cerebrovascular disease.

Purpose

The region of growth (ROG) of geographic atrophy (GA) throughout the macular area has an impact on visual outcomes. Here, we developed multiple deep learning models to predict the 1-year ROG of GA lesions using fundus autofluorescence (FAF) images.

Design

In this retrospective analysis, 3 types of models were developed using FAF images collected 6 months after baseline to predict the GA lesion area (segmented lesion mask) at 1.5 years, FAF images collected at baseline and 6 months to predict the GA lesion at 1.5 years, and FAF images collected 6 months after baseline to predict the GA lesion at 1 and 1.5 years. The 1-year ROG from the 6-month visit was derived by taking the difference between the GA lesion area (segmented lesion mask) at the 1.5-year and 6-month visits.

Participants

Patients enrolled in the following lampalizumab clinical trials and prospective observational studies: NCT02247479, NCT02247531, NCT02479386, and NCT02399072.

Methods

Datasets of study eyes from 597 patients were split into model training (310), validation (78), and test sets (209), stratified by baseline or initial lesion area, lesion growth rate, foveal involvement, and focality. Deep learning experiments were performed using the 2-dimensional U-Net; whole-lesion and multiclass models were developed.

Main Outcome Measures

The performance of the models was evaluated by calculating the Dice score, coefficient of determination (R2), and the squared Pearson correlation coefficient (r2) between the true and derived GA lesion 1-year ROG.

Results

The model using baseline and 6-month FAF images to predict GA lesion enlargement at 1.5 years had the best performance for the derived 1-year ROG. Mean Dice scores were 0.73, 0.68, and 0.70 in the training, validation, and test sets, respectively. The R2 (0.77, 0.53, and 0.79) and r2 (0.83, 0.61, and 0.79) showed similar trends across the 3 sets.

Conclusions

These findings show the potential of using baseline and/or 6-month visit FAF images to predict 1-year GA ROG using a deep learning approach. This work could potentially help support decision-making in clinical trials and more informed treatment decisions in clinical practice.

Purpose

Neurotrophic keratopathy is part of the leprosy sequelae and causes progressive deterioration of visual acuity. Although leprosy is bacteriologically curable, there is currently no efficient treatment. Eye drops containing tetrapeptides, phenylalanine-glycine-leucine-methionine-amide (FGLM-NH2) and serine-serine-serine-arginine (SSSR), derived from substance P and insulin-like growth factor 1, are clinically efficacious in the treatment of corneal epithelial disorders caused by neurotrophic keratopathy. To further investigate the effect of this treatment on leprosy sequalae, we evaluated the clinical efficacy of FGLM-NH2+SSSR eye drops for treating neurotrophic keratopathy.

Design

Clinical trial: interventional, multicenter, exploratory, single-arm, before and after comparison.

Participants

The eyes (12) of 11 patients, aged >60 years, were studied from 2 leprosy sanatoriums in Japan.

Methods

Patients with neurotrophic keratopathy in leprosy sanatorium, specifically those with corneal perception of <40 mm, assessed by the Cochet-Bonnet corneal esthesiometer, and persistent corneal epithelial defects (PEDs) or corneal stromal thinning, or both, were included in this study. Those treated for infection in the acute phase were excluded from the study. Eye drops containing FGLM-NH2 0.05% and SSSR 5 × 10-6% were administered 4 times daily for up to 3 months. Fluorescein staining and optical corneal sections were photographed using a slit lamp microscope at protocol-set intervals. Where possible, anterior segment OCT was performed before and after the intervention.

Main Outcome Measures

The primary outcome measured was improvement in neurotrophic keratopathy. The patient was judged to have improved when ≥1 of the following criteria were met: (1) healing epithelial defects or (2) increased thickness in the thin area of the cornea. Secondary end points were visual acuity, subjective findings, and time to complete healing for a PED.

Results

Neurotrophic keratopathy on epithelial defects or stromal thickness improved in 83.3% of the patients (90% confidence interval 56.2%–97.0%, P < 0.00001). The mean value of corrected visual acuity increased −0.16 by logarithm of the minimum angle of resolution. There were no adverse events reported in association with the treatment.

Conclusions

We confirmed that FGLM-NH2+SSSR eye drops are effective for neurotrophic keratopathy without any adverse reaction in leprosy. These results should be disseminated to any parties who could need this information.

Purpose

Spectral-domain OCT angiography (SD-OCTA) scans were used in an algorithm developed for swept-source OCT angiography (SS-OCTA) scans to determine if SD-OCTA scans yielded similar results for the measurement of hyperreflective foci (HRF) in intermediate age-related macular degeneration (iAMD).

Design

Retrospective study.

Participants

Forty eyes from 35 patients with iAMD.

Methods

Patients underwent SD-OCTA and SS-OCTA imaging at the same visit using a 6 × 6 mm OCTA scan pattern. Hyperreflective foci were detected as hypotransmission defects on en face structural images generated from a custom slab positioned 64 to 400 μm beneath Bruch’s membrane and confirmed on corresponding B-scans by the presence of well circumscribed lesions within the neurosensory retina or along the retinal pigment epithelium (RPE) that are of equal or greater reflectivity than that of the RPE. Two independent graders evaluated the en face images and B-scans for the presence of these lesions. Outlines of HRF on en face images were generated using a published semiautomated algorithm developed for SS-OCTA scans and manually corrected by the graders when necessary. The total area measurements of the HRF within the 5-mm circle centered on the fovea were obtained from the algorithm using each imaging method.

Main Outcome Measures

Agreement of the square root (sqrt) of the HRF total areas obtained from SS-OCTA and SD-OCTA.

Results

The sqrt total areas of the HRF from both imaging modalities were highly concordant, with Lin’s concordance correlation coefficient (rc) of 0.94 (95% confidence interval: 0.86–0.97; P < 0.001). The mean sqrt of the total HRF area measurements identified using SS-OCTA and SD-OCTA imaging were 0.390 mm (standard deviation [SD]: 0.170) and 0.393 mm (SD: 0.187), respectively with mean difference of −0.003 (95% confidence interval: −0.021 to 0.015; P=0.76).

Conclusions

Spectral-domain OCT angiography scans yielded results similar to SS-OCTA scans when the same semiautomated algorithm was used to measure HRF in the central 5 mm of the macula, suggesting that either a single 6 × 6 mm SD-OCTA or a SS-OCTA scan pattern can be used to determine the total macular HRF burden in eyes with age-related macular degeneration.

Purpose

To evaluate the 6-month progression of retinal capillary perfusion in eyes with advanced stages of nonproliferative diabetic retinopathy (NPDR).

Design

RICHARD (NCT05112445), 2-year prospective longitudinal study.

Participants

Sixty eyes with Diabetic Retinopathy Severity Scale (DRSS) levels 43, 47, and 53 from 60 patients with type 2 diabetes. Fifty-one patients completed the 6-month evaluation.

Methods

Eyes were evaluated on Optos California (Optos plc) ultrawidefield fundus fluorescein angiography (UWF-FFA), swept-source OCT angiography (SS-OCTA) (PLEX Elite 9000, ZEISS) and spectral-domain OCTA (SD-OCTA) (CIRRUS HD-OCT 5000 Angioplex, ZEISS). DRSS classification was performed based on 7-field color fundus photographs (CFPs) complemented with Optos California UWF-fundus imaging.

Main Outcome Measures

Ischemic index was obtained from Optos. Vascular quantification metrics, namely foveal avascular zone, skeletonized vessel density (SVD), and perfusion density (PD) metrics, were acquired on OCTA in the superficial and deep capillary plexuses (SCP and DCP). Microaneurysm assessment was automatically performed based on CFP images using the RetmarkerDR (Retmarker SA, Meteda Group).

Results

Swept-source-OCTA metrics showed statistically significant differences between the advanced stages of NPDR. Differences between DRSS levels 47 and 53 were found at baseline in the inner ring (SVD, SCP: P = 0.005 and DCP: P = 0.042 and PD, SCP: P = 0.003) and outer ring (SVD, SCP: P = 0.007 and DCP: P = 0.030 and PD, SCP: P = 0.020 and DCP: P = 0.025). No significant differences were observed at baseline between DRSS levels 43 and 47. In SD-OCTA, the differences were similar but did not reach statistical significance. The total ischemic index showed an increase in association with diabetic retinopathy (DR) severity, but the differences between DRSS levels did not reach statistical significance. The number of microaneurysms also increased significantly with DR severity (P = 0.033). Statistically significant 6-month progression was detected with SS-OCTA in eyes with DRSS levels 47 and 53 but not in DRSS level 43. In eyes with DRSS level 53, 6-month progression was identified using a combination of metrics of capillary nonperfusion and microaneurysm counts.

Conclusions

In a 6-month period, significant microvascular disease progression can be identified in eyes with DRSS levels 47 and 53 by performing OCTA examinations and microaneurysm counting using CFP.

Objective

To demonstrate the capability of a deep learning model to detect central retinal artery occlusion (CRAO), a retinal pathology with significant clinical urgency, using OCT data.

Design

Retrospective, external validation study analyzing OCT and clinical baseline data of 2 institutions via deep learning classification analysis.

Subjects

Patients presenting to the University Medical Center Tübingen and the University Medical Center Hamburg-Eppendorf in Germany.

Methods

OCT data of patients suffering from CRAO, differential diagnosis with (sub) acute visual loss (central retinal vein occlusion, diabetic macular edema, nonarteritic ischemic optic neuropathy), and from controls were expertly graded and distinguished into 3 groups. Our methodological approach involved a nested multiclass five fold cross-validation classification scheme.

Main Outcome Measures

Area under the curve (AUC).

Results

The optimal performance of our algorithm was observed using 30 epochs, complemented by an early stopping mechanism to prevent overfitting. Our model followed a multiclass approach, distinguishing among the 3 different classes: control, CRAO, and differential diagnoses. The evaluation was conducted by the “one vs. all” area under the receiver operating characteristics curve (AUC) method. The results demonstrated AUC of 0.96 (95% confidence interval [CI], ± 0.01); 0.99 (95% CI, ± 0.00); and 0.90 (95% CI, ± 0.03) for each class, respectively.

Conclusions

Our machine learning algorithm (MLA) exhibited a high AUC, as well as sensitivity and specificity in detecting CRAO and the differential classes, respectively. These findings underscore the potential for deploying MLAs in the identification of less common etiologies within an acute emergency clinical setting.

These formulae estimate magnification based on different ocular parameters: AL only (Bennnett’s formula), refractive error only (Bengtsson’s formula), and refractive error combined with keratometry (Littmann’s formula).

目的 视网膜特征的尺寸测量受眼球放大倍数的光学影响。我们研究了眼球放大倍数对轴向长度(AL)和眼底照片中视网膜血管口径测量值之间关联的影响。方法使用半自动软件从彩色眼底照片中得出视网膜中央动脉和静脉等值(CRAE 和 CRVE)。使用普通最小二乘法线性回归评估 AL(自变量)对 CRAE 和 CRVE 的影响,同时控制年龄、性别和种族,并在使用不同公式进行放大校正之前和之后进行校正。这些公式根据不同的眼参数估算放大倍数:仅 AL(Bennnett 公式)、仅屈光不正(Bengtsson 公式)和屈光不正与角膜测量相结合(Littmann 公式)。以往的研究主要依赖 Bengtsson 公式,但其准确性不如 Bennett 公式。结果在放大校正前,AL 的增加与 CRAE(β:-0.49,95% 置信区间:-0.89 至 -0.09,P = 0.02)和 CRVE(β:-0.91,95% 置信区间:-1.62 至 -0.20,P = 0.01)的减少相关。放大校正后,无论采用何种校正公式,这一观察结果都不再明显。当不适当地假设眼底照相机为远心时,我们观察到随着 AL 的增加,放大校正后的 CRAE 和 CRVE 有所增加(β 系数为正或变得更正),使用 Bennett 或 Littmann 公式校正的 CRAE 和使用 Bennett 公式校正的 CRVE 达到了统计学意义(P < 0.05)。结论未对眼球放大率进行校正会导致长眼血管明显变窄,而在放大率校正过程中对远心的不恰当假设则会引入光学假象,导致血管明显变宽。这些发现表明,近视眼视网膜血管口径的变化本质上是光学的(而非生物的)。在研究全身性疾病的视网膜生物标志物的 "眼科组学 "研究中,适当纠正这种效应以准确得出尺寸测量值是一个至关重要但却经常被忽视的方法学考虑因素。

Objective

This study evaluated the safety and efficacy of elamipretide in dry age-related macular degeneration (AMD) with noncentral geographic atrophy (GA).

Design

ReCLAIM-2 was a prospective, phase II, randomized, placebo-controlled, double-masked, multicenter trial (NCT03891875).

Subjects

Patients aged ≥55 years with ≥1 eye with dry AMD with GA were enrolled.

Methods

Administration of daily subcutaneous elamipretide 40 mg was investigated in subjects for 48 weeks followed by a 4-week follow-up period.

Main Outcome Measures

The primary efficacy end points were the mean change from baseline (BL) in low-luminance best-corrected visual acuity (LL BCVA) and the change in square root (Sqrt) converted GA area from BL as measured by OCT. Additional predefined end points included ellipsoid zone (EZ) integrity preservation assessment and categorical changes in LL BCVA. The primary safety end point was the incidence and severity of adverse events.

Results

Of the 176 patients randomized, there were 117 and 59 patients in the elamipretide and placebo groups, respectively. Although elamipretide did not meet statistical significance for the primary end points (mean change in LL BCVA and mean change in Sqrt converted GA area), elamipretide produced a 43% reduction in the mean progression from BL in the macular percentage of total EZ attenuation/loss (i.e., complete loss of EZ band; nominal P = 0.0034) and 47% reduction in the mean progression of macular percentage of partial EZ attenuation/degradation (i.e., EZ-retinal pigment endothelium thickness of ≤20 microns; nominal P = 0.0040) versus placebo at week 48. Elamipretide treatment was also associated with significantly more patients experiencing a ≥10 letter gain in LL BCVA versus placebo (14.6% vs. 2.1%; nominal P = 0.0404). Adverse events were reported in 86% of those receiving elamipretide and 71% of the placebo group with the most common events being injection site reactions (e.g., pruritus, injection site pain, bruising, and erythema).

Conclusions

While the primary end points were not met in this phase II study, elamipretide treatment was associated with a slowing of progressive EZ degradation/loss, a surrogate for photoreceptor damage. These findings have important clinical relevance since EZ attenuation/photoreceptor loss precedes and predicts the progressive pathological changes associated with vision loss and AMD. The EZ attenuation/loss end point will serve as the regulatory approved primary end point in the elamipretide phase III clinical development program.

研究对象年龄≥55岁且有≥1只眼睛患有干性AMD并伴有GA的患者。方法每天皮下注射艾拉莫雷特40毫克,持续48周,然后进行4周随访。主要结果测量主要疗效终点是低照度最佳校正视力(LL BCVA)与基线(BL)相比的平均变化,以及OCT测量的GA面积与基线相比的平方根(Sqrt)转换变化。其他预定义终点包括椭圆体区 (EZ) 完整性保存评估和 LL BCVA 的分类变化。主要的安全性终点是不良事件的发生率和严重程度。结果 在随机抽取的176名患者中,艾拉米雷特组和安慰剂组分别有117名和59名患者。虽然艾拉莫雷特在主要终点(LL BCVA 平均变化和 Sqrt 转换 GA 面积平均变化)上未达到统计学意义,但艾拉莫雷特使黄斑总 EZ 衰减/损失百分比从 BL 开始的平均进展减少了 43%(即 EZ 带完全损失;名义 P=0.05)、第 48 周时,与安慰剂相比,黄斑部分 EZ 衰减/退化(即 EZ-视网膜色素内皮厚度≤20 微米;标称 P = 0.0040)的平均进展减少了 47%。与安慰剂相比,更多患者的LL BCVA增加了≥10个字母(14.6%对2.1%;标称P = 0.0404)。接受艾拉米雷特治疗的患者中有86%出现了不良反应,而安慰剂组中有71%出现了不良反应,其中最常见的不良反应是注射部位反应(如瘙痒、注射部位疼痛、瘀伤和红斑)。结论虽然这项II期研究没有达到主要终点,但艾拉米雷特治疗与减缓EZ的进行性降解/丧失有关,EZ是光感受器损伤的替代物。这些发现具有重要的临床意义,因为EZ衰减/光感受器损失先于并预示着与视力下降和老年性黄斑变性相关的渐进性病理变化。EZ衰减/损失终点将作为艾拉米雷肽III期临床开发计划中经监管部门批准的主要终点。

Objective

Our objectives were to identify correlation patterns between complement and lipid pathways using a multiomics data integration approach and to determine how these interconnections affect age-related macular degeneration (AMD).

Design

Nested case-control study.

Subjects and Controls

The analyses were performed in a subset of the Singapore Indian Eye Study. We randomly selected 155 AMD cases and age- and sex-matched them with 155 controls.

Methods

Firstly, a multiomics data integration method was used to identify correlation patterns between the omics data. Then, we tested possible interactions between the lipids and complement proteins using logistic regression models.

Main Outcome Measures

Age-related macular degeneration was determined according to the Beckman classification system. We measured in serum samples 35 complement proteins and 66 lipids, and used 9 genetic variants.

Results

Among the 155 AMD cases, 93 (60.0%) had early and 62 (40.0%) intermediate AMD. Firstly, we identified 2 clusters between complement proteins and lipids involving (1) mannan-binding lectin serine protease 1 and several different high-density lipoprotein particles, and (2) complement factor H-related protein 1, carboxypeptidase N subunit 2 and complement component C8 gamma chain, and sphingomyelin and different cholesterol. Secondly, we identified 1 interaction between complement protein 1R and sphingomyelin with an odds of AMD 2 times higher for individuals with low levels of sphingomyelin and complement protein 1R (odds ratio = 2.13 [1.09, 4.17]).

Conclusions

We report here, using a cutting-edge multiomics integration approach, the complex interconnections between genetic, metabolomics, and proteomic data. This method permitted us to obtain a holistic picture and identify multiomics signature of AMD pathophysiology. These results advocate for a personalized therapeutic approach that accounts for multiple pathways. However, these results need to be validated in larger studies with different ethnic groups.

目标我们的目标是利用多组学数据整合方法确定补体和脂质通路之间的相关模式,并确定这些相互联系如何影响年龄相关性黄斑变性(AMD)。我们随机选取了 155 例 AMD 病例,并将其与 155 例对照组进行了年龄和性别匹配。主要结果测量根据贝克曼分类系统确定年龄相关性黄斑变性。我们测量了血清样本中的 35 种补体蛋白和 66 种脂质,并使用了 9 种遗传变异。结果在 155 例 AMD 病例中,93 例(60.0%)为早期 AMD,62 例(40.0%)为中期 AMD。首先,我们在补体蛋白和脂质之间发现了2个群集,涉及(1)甘露结合凝集素丝氨酸蛋白酶1和几种不同的高密度脂蛋白颗粒,以及(2)补体因子H相关蛋白1、羧肽酶N亚基2和补体成分C8γ链,以及鞘磷脂和不同的胆固醇。其次,我们在补体蛋白 1R 和鞘磷脂之间发现了一种相互作用,鞘磷脂和补体蛋白 1R 含量低的个体患老年痴呆症的几率要高出 2 倍(几率比 = 2.13 [1.09, 4.17])。通过这种方法,我们获得了一个整体图像,并确定了 AMD 病理生理学的多组学特征。这些结果为考虑多种途径的个性化治疗方法提供了依据。然而,这些结果还需要在不同种族群体的大型研究中得到验证。

Objective

To investigate the effects of oral baricitinib on ocular surface disease (OSD) in patients with chronic graft-versus-host disease (cGVHD).

Design

Prospective phase 1 to 2 single institution trial.

Subjects

Eighteen patients with ocular graft-versus-host-disease (oGVHD) and systemic steroid-refractory cGVHD.

Methods

Oral baricitinib (2 mg and 4 mg) was administered daily for up to 12 months in an intrapatient dose-escalation design. National Institutes of Health (NIH) oGVHD score, vision, corneal Oxford staining (COS), tear break-up time (TBUT), Schirmer I test (ST) without anesthesia, and microliter tear equivalent conversion were assessed at baseline, 6 months (primary efficacy end point), and 12 months if patients remained on the drug.

Main Outcome Measures

Improvement in NIH oGVHD score, COS, TBUT, and ST results in patients with and without conjunctival fibrosis at 6 months.

Results

At 6 months, the NIH oGVHD score significantly improved (P = 0.014) with all OSD parameters also showing improvement, though not statistically significant. COS baseline, 2.17 to 0.95; TBUT baseline, 6.66 to 8.18 seconds, Schirmer I baseline, 3.86 mm (2.6 μl) to 5.56 mm (3.9 μl). For patients continuing treatment at 12 months improvements persisted compared with the baseline but remained statistically nonsignificant. Corneal Oxford staining decreased to 0.94; TBUT increased to 8.95 seconds, and ST improved to 10.19 mm (7.2 μL). Conjunctival fibrosis was present in 39% (n = 7) of the patients at baseline. The greatest improvement was observed in the 11 patients without prior conjunctival fibrosis compared with the baseline: COS 1.84, TBUT 6.32 seconds, ST 4.07 mm (2.1 μl); 6 months: COS 0.25 (P = 0.018), TBUT 8.62 seconds, ST 9.12 mm (5.4 μl); 12 months: COS 0, TBUT 10.29 seconds, ST 16.88 mm (10.6 μl). Vision was stable in all groups. Two patients developed asymptomatic, self-limited conjunctival papillomas, and 1 patient developed uncomplicated bacterial conjunctivitis twice. No dose limiting toxicity was observed. Severe adverse events with hospitalizations for possible drug-related systemic infections occurred in 5 patients.

Conclusions

Systemic baricitinib was well-tolerated, improved NIH oGVHD scores and OSD parameters in patients with oGVHD, with the greatest benefits observed in patients without pre-existing conjunctival fibrosis. Conjunctival fibrosis may affect outcomes and should be considered in patient selection for clinical trials.

The greatest improvement was observed in the 11 patients without prior conjunctival fibrosis compared with the baseline: COS 1.84, TBUT 6.32 seconds, ST 4.07 mm (2.1 μl); 6 months: COS 0.25 (<em>P</em> = 0.018), TBUT 8.62 seconds, ST 9.12 mm (5.4 μl); 12 months: COS 0, TBUT 10.29 seconds, ST 16.88 mm (10.6 μl). Vision was stable in all groups. Two patients developed asymptomatic, self-limited conjunctival papillomas, and 1 patient developed uncomplicated bacterial conjunctivitis twice. No dose limiting toxicity was observed. Severe adverse events with hospitalizations for possible drug-related systemic infections occurred in 5 patients.</div></div><div><h3>Conclusions</h3><div>Systemic baricitinib was well-tolerated, improved NIH oGVHD scores and OSD parameters in patients with oGVHD, with the greatest benefits observed in patients without pre-existing conjunctival fibrosis. Conjunctival fibrosis may affect outcomes and should be considered in patient selection for clinical trials.</div></div><div><h3>Financial Disclosure(s)</h3><div>Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.</div></div>","PeriodicalId":74363,"journal":{"name":"Ophthalmology science","volume":"5 1","pages":"Article 100627"},"PeriodicalIF":3.2,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
