Purpose

This study presents 2 methods of en face visualization enabled by ultra-widefield (UWF) OCT, which provide topographic information of retinopathy of prematurity (ROP) without requiring direct visualization of cross-sectional scans.

Design

Evaluation of diagnostic technology.

Subjects

Infants undergoing ROP screening at Oregon Health Science University between June 2023 and October 2024, who consented to research imaging.

Methods

An investigational contact-based UWF-OCT captured 800 × 800 A-scans. Max intensity projections (MIP) were constructed, from the highest intensity pixel in each A-scan's x-y coordinate plane. Retinal thickness maps (RTMs) were generated by first segmenting the retina with a previously trained U-net, then calculating the retinal thickness at each position in microns, and displaying it with a topographic colormap.

Main Outcome Measures

Cross-sectional and longitudinal qualitative evaluation of the diagnostic utility of MIP and RTM across the spectrum of ROP stage.

Results

MIP highlights areas of high signal attenuation, such as blood vessels and the atypical neurovascular thickening accompanying stage 1 or greater ROP. Retinal thickness maps reflect thickness information in the retina that highlights complementary aspects of the progression and spectrum of the stage. Retinal thickness maps also reveal subclinical elements of ROP morphology, such as the foveal contour, in some cases “stage 0” ROP, and cystoid macular edema.

Conclusions

This study presents 2 techniques to visualize pathology in ROP from UWF-OCT. Together, they enable both high-contrast visualization of the vascular features of ROP and the associated topographic changes across the spectrum of ROP.

Objective

To evaluate whether low serum vitamin D level is a risk factor for proliferative vitreoretinopathy (PVR) after primary rhegmatogenous retinal detachment (RRD) repair.

Design

Retrospective, multisite, case–control study.

Participants

Subjects undergoing pars plana vitrectomy (PPV), scleral buckle (SB), or combined PPV/SB for primary RRD in the Veterans Administration Healthcare System between January 1, 2015, and January 1, 2020. Subjects were required to have a serum 25-hydroxy vitamin D measurement within 1 year of RRD surgery and to have greater than 90 days' follow-up after surgery.

Methods

Clinic notes and operative reports were reviewed to collect the following data points: sex, race, age, geographic location, date of diagnosis, eye laterality, macula and lens status, symptom duration, date and type of surgery, number and location of retinal tears, extent of RRD, presence of vitreous hemorrhage or choroidal detachment, date and level of vitamin D laboratory draw, development of PVR, and need for additional surgeries.

Main Outcome Measures

Incidence of PVR after surgical RRD repair comparing the normal and low vitamin D groups.

Results

A total of 313 subjects met inclusion criteria, of whom 119 (38.0%) had serum vitamin D levels below the laboratory normal limit. Most subjects were male (96.4%) and White (82.4%). Among all subjects, 42 (13.4%) were diagnosed with PVR after initial surgical repair. On univariate analysis, subjects with low vitamin D levels were almost 4 times more likely to develop PVR than those with normal vitamin D levels (odds ratio [OR], 3.95; 95% confidence interval [CI], 1.98–7.87; P < 0.001). This association of vitamin D level and PVR remained significant in multivariable analysis (OR, 4.27; 95% CI, 2.09–8.69; P < 0.001) and when only considering subjects with a vitamin D laboratory draw before or within 90 days of RRD diagnosis. When evaluating vitamin D level as a continuous variable, each 1 ng/mL decrease in serum vitamin D below the laboratory specified lower limit of normal resulted in a 4% increase in the risk of PVR development (OR, 1.04; 95% CI, 1.02–1.08; P = 0.002).

Conclusions

To the best of our knowledge, this study is the first to report an association between low serum vitamin D levels and an increased risk of PVR development after RRD repair. Future studies with more diverse patient populations are required to verify this potential association.

目的：探讨低血清维生素D水平是否是原发性孔源性视网膜脱离（RRD）修复后增殖性玻璃体视网膜病变（PVR）的危险因素。设计：回顾性、多地点、病例对照研究参与者：在2015年1月1日至2020年1月1日期间，在退伍军人管理局医疗保健系统中接受玻璃体切割（PPV）、巩膜扣（SB）或PPV/SB联合治疗原发性RRD的受试者。受试者被要求在RRD手术后1年内进行血清25-羟基维生素D测量，并在手术后随访超过90天。方法：回顾临床记录和手术报告，收集以下数据点：性别、种族、年龄、地理位置、诊断日期、眼睛侧边、黄斑和晶状体状态、症状持续时间、手术日期和类型、视网膜撕裂的数量和位置、RRD的程度、玻璃体出血或脉络膜脱离的存在、维生素D实验室提取的日期和水平、PVR的发展以及是否需要额外的手术。结果：共有313名受试者符合纳入标准，其中119名（38.0%）血清维生素D水平低于实验室正常限度。以男性（96.4%）和白种人（82.4%）居多。在所有受试者中，42例（13.4%）在首次手术修复后被诊断为PVR。在单因素分析中，维生素D水平低的受试者发生PVR的可能性几乎是维生素D水平正常受试者的4倍（OR 3.95, 95% CI 1.98-7.87）。结论：据我们所知，本研究首次报道了低血清维生素D水平与RRD修复后PVR发生风险增加之间的关联。未来需要更多不同患者群体的研究来验证这种潜在的关联。

Objective

To define the clinical features and genetics of children with retinoblastoma diagnosed at ≥5 years of age.

Design

Retrospective review.

Subjects

Children ≥5 years of age treated for retinoblastoma at a single institution between January 1999 and January 2022.

Methods

A chart review including demographics, genetic testing, laterality, presenting signs and symptoms, initial diagnosis if not retinoblastoma, and procedures performed on affected eyes before diagnosis of retinoblastoma.

Main Outcome Measures

Tumor classification, treatments and outcomes, and genetic data on tumors.

Results

Of the 529 retinoblastoma patients identified, 25 (4.7%) were diagnosed at ≥5 years of age (median age 6.0 years, range 5.1–11.3 years). Most patients (24 of 25, 96%) presented with unilateral disease. Nine of 25 (36%) were misdiagnosed before presentation. Pathogenic RB1 germline mutations were identified in 6 of the 24 (25%) patients who underwent testing; 1 child had a positive family history. Further evaluation in 6 tumors (from 6 patients) identified hypermethylation of the RB1 gene promoter in 2 patients.

Conclusions

Older children with retinoblastoma are commonly misdiagnosed before presentation. Germline predisposition to retinoblastoma was more common than anticipated for patients with late-onset unilateral disease. This may have important implications for treatment and prognosis.

Purpose

To assess factors affecting visual outcomes in endogenous endophthalmitis (EE).

Design

Retrospective cohort study from 8 tertiary care centers.

Participants

Eyes with EE and at least 4 weeks of follow-up.

Methods

Demographics, visual acuity (VA), vitrectomy use, and microbial cultures from blood, aqueous, or vitreous fluid were collected and evaluated relative to change in VA and enucleation/evisceration.

Main Outcome Measures

Presenting VA and microbial culture results associated with improvements to VA.

Results

Two hundred sixty-two eyes from 231 patients diagnosed with EE were evaluated. Eyes presenting with VA of either count fingers or hand motion (CF/HM) had significantly greater improvement in VA, compared with eyes presenting with either VA ≥20/800 or VA of light perception (LP) or no LP (less than or equal to LP) (P < 0.01). Twenty-eight eyes underwent enucleation/evisceration, and 23 (82.1%) of these eyes had VA less than or equal to LP at presentation. Forty-six point 9 percent of all study eyes (139 of 262) were from patients with positive blood cultures. Positive growth from blood cultures was associated with greater odds of VA improvement (odds ratio [OR]: 1.78, confidence interval [CI]: 1.07–2.95, P = 0.03) in all study eyes and reduced odds of enucleation/evisceration in eyes presenting with VA less than or equal to LP (OR: 0.12, CI: 0.04–0.42, P < 0.001). Compared with eyes from patients with positive blood cultures, eyes from patients with negative blood cultures had significantly lower rates of treatment with both systemic antimicrobials and intravitreal antimicrobial injections (P < 0.001). In eyes from patients with negative blood cultures, there was a trend for greater improvement after initial treatment with both antibacterial and antifungal injections compared with initial treatment with either antibacterial or antifungal injection alone (P = 0.05).

Conclusions

Eyes presenting with a VA of CF/HM have the greatest potential for VA improvement. Patients with EE without any organisms identified on blood cultures may benefit from broad initial intravitreal antimicrobial coverage to reduce the odds of worsening VA.

目的：探讨内源性眼内炎（EE）患者视力预后的影响因素。设计：来自8个三级医疗中心的回顾性队列研究。参与者：患有内源性眼内炎的眼睛，随访至少4周。方法：收集人口统计学、视力（VA）、玻璃体切除术的使用，以及血液、水或玻璃体液中的微生物培养物，并评估VA和去核/去内脏的变化。主要结果测量：显示VA和与VA改善相关的微生物培养结果。结果：对231例EE患者的262只眼睛进行了评估。与VA≥20/800或VA光觉或无光觉（≤LP）的眼相比，以数指或手部运动VA （CF/HM）为表现的眼的VA改善显著（p < 0.01）。28只眼行去核/剜出，23只眼（82.1%）就诊时VA≤LP。46.9%的眼睛（139/262）来自血培养阳性患者。在所有研究的眼睛中，血液培养的阳性生长与VA改善的几率更大（OR: 1.78, CI: 1.07 - 2.95, p = 0.03）相关，并且与VA≤LP的眼睛中去核/内脏切除的几率降低相关（OR: 0.12, CI: 0.04 - 0.42, p < 0.001）。与血培养阳性患者的眼睛相比，血培养阴性患者的眼睛接受全身抗菌素和玻璃体内抗菌素注射的治疗率明显较低（p < 0.001）。在血培养阴性患者的眼睛中，与单独使用抗菌或抗真菌注射相比，首次使用抗菌和抗真菌注射后有更大的改善趋势（p = 0.05）。结论：CF/HM的VA有很大的改善潜力。在血液培养中未发现任何微生物的EE患者可能受益于广泛的初始玻璃体内抗菌药物覆盖，以减少VA恶化的几率。

Patients with EE without any organisms identified on blood cultures may benefit from broad initial intravitreal antimicrobial coverage to reduce the odds of worsening VA.</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":19501,"journal":{"name":"Ophthalmology.
