摘要

导言:单眼PPRCA和同眼RP样视网膜病变并存是一种罕见的临床现象,迄今为止公开发表的描述有限。本研究旨在描述三位受此临床表现影响的患者的综合临床评估和长期随访情况:方法:对三位同时患有 PPRCA 和 RP 样视网膜病变的患者进行了前瞻性的重新评估和综合评估。通过将最佳矫正视力(BCVA)和椭圆带(EZ)宽度与每位患者的病历和之前的SD-OCT扫描数据进行比较,评估疾病的进展情况。采集并检测血液样本,以排除自身免疫性或感染性眼部疾病,检测抗视网膜自身抗体(ARA),并进行基因分析:结果:在三位患者中,均发现RP样表型眼的BCVA下降,EZ带随时间推移呈进行性同心性缺失,而在PPRCA眼中,没有一位患者的BCVA出现明显变化,只有一位患者的EZ宽度呈进行性下降。目前尚未发现明确的病因。三位患者中有两位检测出两种或两种以上的ARA亚型:结论:PPRCA被证明是一种非进行性或缓慢进行性疾病,而具有RP样表型的眼睛却表现出进行性视力损害,这凸显了揭示这种疾病的重要性。该病的病因仍不清楚:两只眼睛的表型不同可能与遗传特征有关,也可能与 ARAs 的潜在作用有关。

Pigmented paravenous retinochoroidal atrophy and retinitis pigmentosa-like phenotype in the same patient: A case series.

Introduction: Concomitant manifestation of PPRCA in one eye and RP-like retinopathy in the fellow eye is a rare clinical entity, with limited published descriptions to date. The aim of this study is to describe comprehensive clinical evaluations and long-term follow-up of three patients affected by this clinical picture.

Methods: Three patients with concurrent PPRCA and RP-like retinopathy were prospectively re-evaluated and comprehensive assessments were performed. The progression of disease was assessed by comparing best corrected visual acuity (BCVA) and ellipsoid zone (EZ) width with data available from each patient's medical charts and previous SD-OCT scans. Blood samples were collected and tested to rule out autoimmune or infectious ocular diseases, for testing anti-retinal autoantibodies (ARAs) and for genetic analysis.

Results: Reduction in BCVA and a progressive concentric loss of the EZ band over time were detected in the eye with RP-like phenotype in all three patients, while in the eye with PPRCA none of the patients showed significant changes in BCVA and only one patient showed a progressive reduction of the EZ width. No clear etiology has been identified. Two or more ARAs subtypes were detected in two out of three patients.

Conclusions: PPRCA was demonstrated to be a non-progressive or slowly progressive disease, instead the eye with RP-like phenotype showed a progressive visual impairment, highlighting the importance of shedding light on this condition. Its etiology remains unclear: a genetic trait with different phenotype between the two eyes is conceivable, as well as a potential role of ARAs.
