Optical coherence tomography to detect macular edema in the presence of asteroid hyalosis.

Abstract

To propose the use of optical coherence tomography as an effective diagnostic tool for identifying macular edema in patients with asteroid hyalosis obscuring the fundus view. Case report. Review of clinical chart and images. Private retina practice. One patient diagnosed with diabetic retinopathy and asteroid hyalosis, who was experiencing decreased visual acuity and whose fundus view was inadequate for diagnosis using customary techniques. Usual methods of diagnosis were ineffective until OCT obtained a clear image of the fundus and subsequent macular thickening with vitreomacular adhesion. Optical coherence tomography is an effective diagnostic tool for discovering macular edema in cases of dense asteroid hyalosis where traditional methods fail to obtain a clear image of the fundus.
