Abstract

Purpose: : To evaluate differences in the visualization of vitreo-retinal interface analyzed by Time Domain OCT (STRATUS, Carl Zeiss Meditech, Dublin, California) and Spectral Domain OCT (CIRRUS, Carl Zeiss Meditech, Dublin, California).

Methods: : We reviewed a case series of 47 consecutive subjects who underwent Stratus OCT and Cirrus OCT examination the same day. Scanning protocols used were Macular Thickness Map ( Stratus OCT) and 5 Line Raster-Macular Cube 512x128 (Cirrus OCT). Each scan was manually analyzed by an experienced retinal specialist in order to determine the presence of the following clinical features: 1. Absence of Posterior Vitreous Detachment (PVD), 2. Complete PVD, 3. Perifoveal Vitreous Detachment (Incomplete PVD Nasally and Temporally causing a V-shaped pattern) and 4. Epiretinal Membrane.Statistical test: Mc Nemar’s chi square.

Results: : 83 eyes of 47 subjects were examined. Overall, Cirrus OCT detected one of the previous 4 vitreo-retinal clinical features in 66 of 83 eyes (79,51%) as compared with 40 of 83 eyes (48,19%) using OCT Stratus. Absence of PVD was identified in 1 of 83 eyes ( 1,2%) using OCT Stratus compared with 10 of 83 eyes (12,04%) using OCT Cirrus (p=0,026). Complete PVD was identified in 11 of 83 eyes (13,2%, Stratus) and 21 of 83 eyes (25,3%, Cirrus) (p=0,0015). Perifoveal PVD was identified in 9 of 83 eyes (10,8%,Stratus) and 19 of 83 eyes ( 22,8%, Cirrus) (p=0,0015). Epiretinal Membrane was identified in 21 of 83 eyes ( 25,3%, Stratus) and 31 of 83 eyes (37,3%, Cirrus) (p=0,0015).

Conclusions: : OCT Cirrus is more sensitive than OCT Stratus in detecting the absence of PVD and the presence of Complete PVD, Perifoveal PVD and Epiretinal Membrane.
