Snakebite is an important but neglected health hazard with significant morbidity and mortality and is more prevalent in tropical countries.1 Venomous snakebites may result in neurologic or hemostatic dysfunction with multisystem involvement depending on the type of envenomation. Many victims survive with permanent physical and psychological morbidity, including ocular morbidity.2 Studies have reported ocular manifestations after venomous snakebites in 1% to 27% cases.1–3 Although ocular involvement after snake bite is not very uncommon, vision-threatening complications are infrequent, including acute angle closure glaucoma, vitreous and retinal hemorrhage, central retinal artery occlusion (CRAO), macular infarction, exudative retinal detachment, optic neuritis, globe necrosis, endophthalmitis, and blindness caused by cortical infarction.
