Abstract

Background/aim: This case report aims to describe an unusual angiographic finding of smoke-stack leakage (SSL) in a vitrectomised eye of a patient with proliferative diabetic retinopathy (PDR).

Case description: A 59-year-old male with a 17-year history of type 2 diabetes mellitus underwent fundus fluorescein angiography (FA) following vitrectomy for vitreous hemorrhage secondary to PDR. His visual acuity at the time of FA was 6/6 in both eyes. The examination focused on identifying neovascularization elsewhere (NVE) and analysing leakage patterns. FA revealed active NVEs in the left eye with late-phase leakage nasally and inferiorly to the optic disc, while the right eye exhibited a distinctive SSL pattern from residual proliferation. Interestingly, the leakage subsided in the late phase, leaving only staining of the residual fibrous tissue.

Conclusion: The observed SSL in this vitrectomised eye underscores unique post-surgical dynamics of fluorescein diffusion. This case highlights the importance of recognizing altered leakage patterns in vitrectomised patients, which can impact the evaluation and management of retinal neovascularization in PDR.

玻璃体切除伴增殖性糖尿病视网膜病变眼的烟囱状荧光素渗漏：一种罕见的血管造影现象。

背景/目的：本病例报告描述了一例增殖性糖尿病视网膜病变（PDR）患者玻璃体切除眼的不寻常血管造影发现烟囱渗漏（SSL）。病例描述：59岁男性，17年2型糖尿病病史，因PDR继发玻璃体出血行玻璃体切除术后行眼底荧光素血管造影（FA）。他在FA时双眼视力为6/6。检查的重点是识别其他地方的新生血管（NVE）和分析渗漏模式。FA显示左眼有活动的nve，伴有晚期鼻及视盘下方渗漏，而右眼则因残余增生而表现出独特的SSL模式。有趣的是，渗漏在晚期消退，只留下残余纤维组织的染色。结论：在这只玻璃体切除的眼睛中观察到的SSL强调了荧光素扩散的独特术后动态。该病例强调了在玻璃体切除患者中识别渗漏模式改变的重要性，这可能影响PDR视网膜新生血管的评估和管理。
