Acute retinal necrosis syndrome (ARN) is a viral infection characterized by focal retinal necrosis. Viral meningitis complicated by ARN is relatively rare. In the present case study, a 44-year-old male presented with fever, headache and mental disorder. After four days, the patient developed blurred vision. The patient was diagnosed with viral encephalitis complicated by bilateral ARN, based on the examination results. After treatment with antivirals and systemic glucocorticoids, the symptoms of the patient improved. Viral encephalitis may be an important risk factor for ARN. For a patient with viral encephalitis who experiences decreased visual acuity or vitreous opacification, the possibility of ARN should be considered.

Herpes simplex virus (HSV) is the most common cause of acute viral encephalitis. Acute retinal necrosis (ARN) is a rapidly progressing and potentially blinding eye disease that may be induced by HSV. The present case study reports the very rare case of a patient with herpes simplex encephalitis (HSE) combined with acute retinal necrosis (ARN). A 47-year-old woman was admitted to hospital with persistent high fever and somnolence for 5 days. Magnetic resonance imaging showed abnormal signals in the right medial temporal lobes, and HSV-1 was identified in the serum and cerebrospinal fluid. Five days later, despite treatment with intravenous acyclovir and partial improvement in consciousness, the patient suddenly developed blurred vision and bilateral visual pain. Fundus fluorescence angiography revealed bilateral vessel obstruction and flaky reduced fluorescence. ARN was diagnosed clinically. Dexamethasone was administered as an anti-inflammatory adjunct to intravenous acyclovir therapy. The visual acuity of the patient was reduced to mere light perception a further 4 days later. The present case indicates that HSE may be complicated with ARN, causing a reduction in visual acuity to mere light perception within a very short time.

Acute retinal necrosis (ARN) is a rapidly progressive disease with poor prognosis, leading to visual loss in most cases. Rapid diagnosis and early anti-viral treatment significantly affect the course and prognosis of the disease. In this case report, we present a 34-year-old female patient referred to our clinic with symptoms of blurred vision and ocular pain diagnosed as acute glaucoma elsewhere. A clinical diagnosis of ARN was made and anti-viral treatment was started immediately. We herein describe our treatment approach to this particular case and discuss previously reported treatment modalities.
