Visual field defects in neurocysticercosis: A rare presentation

Neurocysticercosis is one of the commonest helminthic infections which affects central nervous system in humans and is caused by a tapeworm , Taenia solium . A 46-year-old male patient reported with complaint of restricted visual field in the left eye for one week. His best-corrected visual acuity was 6/6 partial, N6 in both eyes. Perimetry confirmed left homonymous hemianopia. The patient was referred to a neurophysician and based on magnetic resonance imaging brain and positron emission tomography scan, the patient was diagnosed with neurocysticercosis. The subject was started on oral medications following which the lesion resolved and improvement in visual fields was seen at one month follow-up. Ophthalmic manifestations of neurocysticercosis are variable and may include rare symptoms like visual field defects. A multimodal imaging and multidisciplinary approach can be helpful in the early diagnosis and faster recovery in patients with neurocysticercosis.
