Monocular blindness during therapy for cerebral neurocysticercosis.

ABSTRACT

Neurocysticercosis is endemic in India, cerebral and ocular manifestations being common. A 32 yr old man on treatment with Albendazole for cerebral neurocysticercosis for 10 days presented with 3 days of painful uniocular blindness. He had only light perception in the left eye, left pupil was non-reactive to light and left disc was edematous. B-scan of eye revealed retinal detachment due to sub retinal cyst and CT brain showed multiple parenchymal cysticerci. The natural history of ocular neurocysticercosis or enhanced sub-retinal inflammation due to Albendazole therapy could have resulted in the retinal detachment in this case.
