Emerging evidence has suggested that macular microcirculation and microstructural changes after rhegmatogenous retinal detachment (RRD) successful reattachment surgery are currently evaluated in detail by OCT-Angiography (OCT-A). New imaging technology has revealed the existence of microscopic macular changes, even in cases that retinal morphology appears to be normal in fundus biomicroscopy. The use of OCT-A for the examination of foveal characteristics has attracted significant attention in recent years as the technique offers a potential explanation of the suboptimal recovery of visual acuity and incomplete restoration of the macula despite anatomical repair. However, the available evidence that is needed to establish the OCT-A parameters as predicting factors in clinical practice is both limited and contradictory.
A detailed review of the literature was conducted. The association of OCT-A characteristics with postoperative visual acuity after RRD surgery, including vitrectomy with gas tamponade and in some cases scleral buckle, was extensively analyzed.
A comprehensive update on microcirculation and microstructural changes of the macula using OCT-A after RRD repair may indicate potential factors of functional outcomes in clinical practice.
A review of the existing literature sheds light on the microvascular changes of the macular capillary plexus that may significantly affect functional outcomes after RRD surgery. The current article discusses important aspects of key publications on the topic, highlights the importance of long-term effectiveness of these possible prognostic factors and proposes the need for further future research.
有新的证据表明，在孔源性视网膜脱离（RRD）成功复位手术后，黄斑微循环和微结构的变化目前正在通过 OCT 血管造影（OCT-A）进行详细评估。新的成像技术揭示了微观黄斑变化的存在，即使眼底生物显微镜检查显示视网膜形态正常。近年来，OCT-A 用于检查黄斑特征引起了广泛关注，因为该技术可能解释了尽管解剖修复，但视力恢复不佳和黄斑未完全恢复的原因。然而，需要建立 OCT-A 参数作为临床实践预测因素的证据既有限又相互矛盾。
对文献进行了详细回顾。广泛分析了 OCT-A 特征与 RRD 手术后视力的关系，包括玻璃体切割联合气体填充，在某些情况下还包括巩膜扣带。
RRD 修复后使用 OCT-A 对黄斑微循环和微结构变化的全面更新可能表明临床实践中功能结果的潜在因素。
对现有文献的回顾揭示了黄斑毛细血管丛的微血管变化，这些变化可能会显著影响 RRD 手术后的功能结果。本文讨论了关于该主题的重要出版物的要点，强调了这些可能的预后因素的长期有效性的重要性，并提出了进一步研究的必要性。
