Abstract

Objective: The purpose of this study is to enhance the known onset time of acute retinal necrosis syndrome and explain the reason of different prognosis of acute retinal necrosis. Method: Three patients were examined by neurology and ophthalmology. Possible pathogenesis was analyzed. Results: The 3 patients were 37-year-old male, 49-year-old female and 47-year-old male respectively. After being presented at diagnosis, they had herpetic encephalitis associated with acute retinal necrosis syndrome and all the examinations are consistent with herpetic infection. Conclusion: The key to influence the vision is the vision correction at preliminary diagnosis and central retinal artery occlusion and pathogenesis in the acute phase may relate to chemotaxis ability of T cell.
