To investigate the fundus manifestation of patients with acute retinal necrosis (ARN) examined by optical coherence tomography (OCT).

OCT, best corrected visual acuity, slit lamp anterior segment examination, indirect ophthalmoscope after mydriasis, color fundus photography, visual field, corneal endothelial examination and fundus fluorescein angiography were performed for 9 patients with ARN. The fundus changes of OCT were analyzed.

Total of 11 eyes fundus examination of 9 patients showed vitreous opacity, focal lamellar retinal necrosis of the fusion area, retinal vessel occlusion is white linear. The clinical diagnosis of ARN patients was based on typical fundus findings: yellow-white retinal necrosis, occlusive retinopathy, anterior chamber and vitreous inflammatory cells, etc. Patients with ARN were treated with acyclovir intravenously and vitrification in the event of retinal detachment.

The specific lesions observed on the OCT color fundus were consistent with the OCT images. Early and timely diagnosis and timely treatment of ARN patients by OCT could significantly improve their visual function and life quality.
