We presented an unusual case of ophthalmic herpes zoster masquerading as orbital cellulitis, resulting in delay in appropriate treatment. A 65-year-old woman presented with left periorbital pain and swelling of a week duration. Examination revealed periorbital edema and inflammation but no proptosis. The erythema extended onto the brow. There was no change in visual acuity and cranial nerve function was normal. She was apyrexial and all other parameters were within normal limits. The patient was admitted with an initial diagnosis of sinusitis with orbital cellulitis/dacryocystitis and intravenous co-amoxiclav and a non-steroidal anti-inflammatory drug were administered. The following day, there was little change in her condition with the ocular movements being normal and vision remaining unaffected. She was apyrexial but the periorbital swelling persisted. Computed tomography of the sinuses did not show sinusitis or a periorbital collection. The third day after admission and 10 days after the initial appearance of pain, vesicles appeared on the left forehead, which enabled a diagnosis of herpes zoster of the ophthalmic branch of the trigeminal nerve. She was then treated with acyclovir with a good result.
