Visual evoked response in macular diseases.
Visual evoked responses (VER) were recorded in 10 patients with unilateral maculopathy. VER latency and amplitude were compared between the affected and unaffected eyes. Evaluation of results reveals that in macular disease with fluid accumulation (Central Serous Retinopathy and Traumatic Macular Oedema) the VER showed amplitude reduction depending on reduced visual acuity with no significant change in latency, whereas, in disease with degeneration of retinal layers, (Degenerative Maculopathy) latency was markedly increased signifying associated conduction defect.
