Purpose

To describe vitreoretinal interface abnormalities detected by SD-OCT in eyes with macular edema associated with retinal vein occlusion (RVO).

Setting/Venue

Hedi Raies Institute, Ophthalmology Department B.

Methods

A total of 42 eyes (40 patients) with macular edema associated with RVO and treated with intravitreal bevacizumab injection were retrospectively analyzed on spectral-domain optical coherence tomography (SD-OCT) initially and at 24 months.

Results

The mean age of patients was 56 years and the mean number of injections was 7.49 at 24 months. Using SD-OCT, vitreoretinal interface abnormalities were detected in 31 eyes (73.8%) and were significantly more frequent in central vein occlusion (P<0.001). There was vitreomacular adhesion without traction in 3 eyes (7.1%) and with traction in 1 eye (2.4%). Epiretinal membranes were present in 25 eyes (59.5%) and were globally adherent in 19 eyes (70.4%) and focally adherent in 4 eyes (14.8%). A lamellar macular hole was present in 3 eyes and a full-thickness macular hole in one eye.

Conlusions

Vitreoretinal interface abnormalities seem to be frequent in macular edema associated with RVO and treated with intravitreal bevacizumab.
