Background: Snake bite is a neglected public health problem worldwide especially in the tropics. Studies on ocular manifestations are still fragmentary. The objective of the study was to find ocular manifestations among the snake bite cases with systemic envenomation admitted in the intensive care units in a tertiary care hospital in rural North Kerala, India during a period of 4 years from May 2012 to May 2016.Methods: It was a prospective, observational, cross sectional study. Institutional ethical committee approval was obtained for the study. A descriptive analysis of snake bite cases with systemic envenomation was done. Other snake bites are excluded from the study. Patients who needed ophthalmological opinion for ocular symptoms were analyzed.Results: Total suspected snake bites admitted in ICUs during the study period were 638. Only 7 patients (1%) with haematotoxic envenomation needed ophthalmological opinion for ocular symptoms. Patients in the present study ranged between the age of 11 and 53. Ocular lesions diagnosed among the 6 patients who developed capillary leak syndrome, were bilateral angle closure glaucoma in 3 patients, pan uveitis, disc edema and retinal haemorrhages in 2 patients, bilateral macular oedema. Youngest patient had intracranial haemorrhage and bilateral orbital hemorrhage, leading to exposure keratitis. SAV was administered in all patients ranging from 11-30 vials. All the patients except the patient with orbital haemorrhage had a grave prognosis. Still only one of these patients expired on day 3, rest all patients had better vision and survived due to timely management.Conclusions: A timely intervention especially at the initial presentation of capillary leak syndrome, can decrease the morbidity and save the life of a patient.

“…However, subconjunctival hemorrhage, hyphema, retinal and vitreous hemorrhages are well-known effects of viper envenomation. Other rare problems described included ptosis, ophthalmoplegia, keratomalacia, uveitis, central retinal artery occlusion, unilateral or bilateral optic neuritis, visual loss due to cortical infarction, and macular infarction (3)(4)(5)15).…”

Snakebites are endemic in some parts of Thailand, being associated with several complications. Ocular disturbances are uncommon, except in cases of corneal or conjunctival injury, when the eye is directly exposed to the snake venom. The present study presents a case of combined ophthalmic artery occlusion and transient central retinal artery occlusion with macular ischemia after a Russell's viper bite.

“…However, the common problem described after snakebites is a neurological disturbance in the form of ophthalmoplegia (3). Other ocular disturbances observed as effects of snakebites range from keratomalacia to vitreous hemorrhage, including uveitis, glaucoma, central retinal artery occlusion, macular infarction, optic neuritis, penetrating eye injury, globe necrosis and visual loss due to cortical infarction (1,(3)(4)(5)(6)(7). The signs, symptoms and magnitude of pit viper envenomation depend on…”

“…Ocular complications are very rare, but common ocular involvements are generally connected with neurological ones. Visual loss subsequent to snakebite may result from neurological or hemostatic abnormalities as well as from direct ocular inoculations (1).…”

Viper venoms act mainly on blood and blood vessels. Reports of ophthalmic manifestations after snakebite include ptosis and ophthalmoplegia. In the current study, we describe a case that developed bilateral retinal and subretinal hemorrhage following snakebite. Bilateral retinal hemorrhage is a rare ocular complication of snake envenomation and has not been reported with fundus photographs in the literature so far.
