Abstract

PURPOSE

To describe the vitreoretinal interface of the asymptomatic fellow eyes of patients with acute unilateral posterior vitreous detachment (PVD) based on biomicroscopic examination and spectral domain optical coherence tomography.

METHODS

Sixty-five eyes of 65 consecutive patients with acute unilateral PVD were examined by slit-lamp, indirect ophthalmoscopy, and spectral domain optical coherence tomography. The state of PVD in different retinal locations and premacular pocket were assessed and graded using spectral domain optical coherence tomography.

RESULTS

Nine eyes (13.85%) had no PVD, 15 (23.08%) had extrafoveal vitreous separation (Stage 1), 18 (27.69%) had partial foveal vitreous separation (Stage 2), 12 (18.46%) had complete foveal vitreous separation (Stage 3), and 11 (16.92%) had a complete PVD (Stage 4). The presence of a premacular pocket showed equal distribution in Stages 0, 1, and 2 (66.67, 80.00, and 77.78%, respectively) but was significantly less common in Stages 3 (P = 0.016) and 4 (P < 0.0001). Only certain posterior vitreous configurations were identified (P < 0.0001), suggesting an orderly progression of PVD evolution.

CONCLUSION

Our spectral domain optical coherence tomography-based PVD staging system describes the evolution of PVDs. This can be used as a guide in predicting the occurrence and evolution of PVD in this population.

摘要

目的

基于生物显微镜检查和光谱域光学相干断层扫描，描述急性单侧玻璃体后脱离（PVD）患者无症状对侧眼的玻璃体视网膜界面。

方法

对65例连续急性单侧PVD患者的65只眼进行裂隙灯、间接检眼镜和光谱域光学相干断层扫描检查。使用光谱域光学相干断层扫描评估并分级不同视网膜位置和黄斑前间隙的PVD状态。

结果

9只眼（13.85%）无PVD，15只眼（23.08%）有黄斑外玻璃体分离（1期），18只眼（27.69%）有部分黄斑玻璃体分离（2期），12只眼（18.46%）有完全黄斑玻璃体分离（3期），11只眼（16.92%）有完全PVD（4期）。黄斑前间隙在0期、1期和2期的出现率分布相同（分别为66.67%、80.00%和77.78%），但在3期（P = 0.016）和4期（P < 0.0001）明显较少见。仅识别出特定的玻璃体后结构（P < 0.0001），提示PVD演变具有有序进展。
