A 35-year-old otherwise healthy man presented with a 1-week history of blurred vision in his RE. Medical history revealed mild chickenpox 3 weeks prior to his presentation, which resolved without complications. On ophthalmic examination, BCVA was 20/40 in the RE and 20/20 in the LE. There was no afferent pupillary defect. The intraocular pressure was 16 mmHg in both eyes. Minimal conjunctival hyperemia was present, and there were a few anterior chamber cells and 3+ vitreous cells and haze in the RE. Funduscopy revealed whitish retinal infiltration affecting the far periphery of the retina in one quadrant. Clinical examination results of the LE were normal.\nA diagnosis of ARN syndrome secondary to chickenpox infection was made, and the patient was treated with intravenous acyclovir (10 mg/kg, three times a day). Seven days later, there was no improvement in the RE, and the patient was given intravitreal ganciclovir (2 mg). After a 10-day course of intravenous acyclovir, the patient received valacyclovir (1000 mg, three times daily). Seven days after initiation of oral antiviral therapy, he received oral prednisone (0.5 mg/kg/day for 1 week, followed by gradual tapering over 8 weeks). Systemic corticosteroids were prescribed because of significant vitritis. BCVA of the RE improved to 20/20, with gradual resolution of vitreous inflammatory reaction. The peripheral retinal lesion healed with a residual chorioretinal scar. No fellow eye involvement or recurrence of ARN was observed after an 18-month period of follow-up.
A 41-year-old man complaining of left visual disturbance visited our department. He had a history of IVH associated with moyamoya disease three months ago. He was comatose at the initial presentation. Computed tomography (CT) at the first visiting hospital demonstrated IVH with hydrocephalus (). Cerebral angiography showed severe bilateral stenosis at the distal internal carotid artery and basal moyamoya vessels. It was compatible with moyamoya disease (). Emergent extraventricular drainage was performed. His mentality gradually improved to alert. Ophthalmologic examination at our hospital detected a vitreous hemorrhage in his left eye (), with right eye remaining normal (). In spite of three months conservative care, his visual acuity was not improved. Vitrectomy with epiretinal membrane removal was performed (). After operation his left visual acuity was recovered.
