Macular hole secondary to branch retinal vein occlusion diagnosed by Retinal Thickness Analyzer.

The Retinal Thickness Analyzer is a laser slit biomicroscopy imaging device that produces accurate measurements of retinal thickness and displays the images in a two-dimensional pattern, superimposed on a fundus image. This article reports a patient with decreased vision following branch retinal vein occlusion in whom the Retinal Thickness Analyzer was used to establish the diagnosis of a macular lamellar hole that was not apparent clinically.
