    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.
