Case Report: Optical Coherence Tomography Findings in Glaucoma with Co-existing Vitamin a Deficiency.

Abstract

This case study reports on the presence of vitamin A deficiency in an adult with asymmetric normal tension glaucoma. The retinal OCT findings demonstrated expected loss of the outer retinal layers, typically seen in Vitamin A deficiency, but also severe and bilateral loss of the inner retinal layers. After Vitamin A supplementation, visual acuity, dark adaptation, and color vision normalized. The outer retinal layers had a restoration of the thickness after vitamin A supplementation but the inner layers did not change. This case is unique because it may give us an insight about the role of vitamin A on the inner retina and demonstrates the recovery of the outer retinal layers with vitamin A supplementation.
