Abstract
PURPOSE: To investigate the prognostic value of optic nerve head swelling (ONHS) in central retinal vein occlusion (CRVO) and compare it to other prognostic factors. METHODS: Seventy-four patients with CRVO were studied retrospectively. The parameters analysed were the initial presence of ONHS, the fluorescein angiographic appearance, the implicit time in the 30-Hz flicker ERG and the initial visual acuity. The aspects of outcome studied were the development of neovascular complications and the visual acuity 1 year after the thrombotic event. RESULTS: Fluorescein angiography, ERG and initial visual acuity were of prognostic value in CRVO, whereas ONHS was of questionable value. CONCLUSION: ONHS is most likely of no prognostic value in CRVO.
