Acute retinal necrosis (ARN) is a rare but potentially devastating condition thought to be caused by the herpes viruses. It usually occurs in otherwise healthy individuals and is characterised by vitritis, retinal vasculitis and necrotising retinitis. Although uveitis and secondary raised intraocular pressure is common, secondary acute angle closure glaucoma (AACG) has not been previously described in association with ARN. The authors present a case of ARN that presented with symptoms and signs masquerading as an attack of primary angle closure glaucoma. This report highlights the importance of considering secondary causes of angle closure in atypical cases of AACG.
