Abstract

Purpose

To describe a novel postoperative OCT finding after rhegmatogenous retinal detachment (RRD) repair and explore its relationship with retinal displacement.

Design

Retrospective consecutive case series.

Participants

Patients with primary RRD with partial macular involvement who underwent successful repair.

Methods

Patients after RRD repair who demonstrated a marginal outer retinal ridge (MORR) on postoperative OCT were included. MORR was defined as a linear outer retinal hyperreflective ridge adjacent and parallel to the RRD margin.

Main Outcome Measures

Clinical characteristics, surgical variables, multimodal imaging findings, and evidence of retinal displacement were assessed.

Results

Twelve eyes were included. MORRs were predominantly located along the inferior RRD margin (11/12) and were detectable as early as postoperative day 1. In 4 of 12 eyes (33.3%), MORRs occurred in regions that were attached at presentation. MORRs resolved spontaneously within months in all cases. In 2 cases, MORR involved the fovea. Retinal displacement was more pronounced superior to a MORR, supporting retinal redundancy as the mechanism of formation.

Conclusions

MORR represents a novel OCT biomarker of retinal displacement and reflects postoperative retinal redundancy. Recognition of MORR provides new insight into the biomechanics of retinal reattachment and may have implications for surgical technique, postoperative imaging, and functional outcomes.

孔源性视网膜脱离修复后的边缘外视网膜嵴：一种新的视网膜移位生物标志物。

目的：描述孔源性视网膜脱离（RRD）修复术后一种新的光学相干断层扫描（OCT）发现，并探讨其与视网膜移位的关系。设计：回顾性连续病例系列。参与者：成功修复的黄斑部分受累的原发性RRD患者。方法：纳入RRD修复术后OCT显示边缘视网膜外脊（MORR）的患者。MORR被定义为与RRD边缘相邻并平行的线性视网膜外高反射脊。主要结局指标：评估临床特征、手术变量、多模态成像结果和视网膜移位的证据。结果：纳入12只眼。morr主要位于RRD下缘（11/12），早在术后第1天就可检测到。在4/12只眼（33%）中，morr发生在呈现时附着的区域。所有病例的morr在几个月内自行消退。在两个病例中，MORR涉及中央窝。视网膜移位比MORR更明显，支持视网膜冗余的形成机制。结论：MORR是一种新的OCT视网膜移位生物标志物，反映了术后视网膜冗余。对MORR的认识为视网膜再植的生物力学提供了新的见解，并可能对手术技术、术后成像和功能结果产生影响。
