Bilateral Acute Anterior Uveitis and Optic Disc Edema Following a Snake Bite
Praveen K Kumar,Shashi Ahuja,Praveen S Kumar 대한안과학회 2014 Korean Journal of Ophthalmology Vol.28 No.2
The authors wish to report a case of bilateral acute anterior uveitis and optic disc edema following ahemotoxic snake bite, in order to highlight the concomitant occurrence of these conditions and the potentialadverse effects of anti-snake venom (ASV). A 35-year-old male was bitten by a viper at seventeen thirtyhours, and was started on ASV. Two days following treatment he experienced sudden onset redness andpainful diminution of vision in both eyes (OU). On examination, the patient’s visual acuity (VA) in OU was 20/ 200. Examination revealed fresh keratic precipitates, cells, and flare in the anterior chamber (AC), posteriorsynechiae, sluggish and ill-sustained pupillary reaction, and hyperemic, edematous disc with blurredmargins in OU. He was started on topical steroids, cycloplegics and intravenous methylprednisolone. Following treatment, the patient showed improvement and was continued on topical medications and oralprednisolone tapered over 3 weeks, after which VA OU improved, the AC showed no cells and flare anddisc edema resolved. Uveitis and optic disc edema in snake bite can either be due to the direct toxic effectsof the venom or the effect of ASV. Steroids have a beneficial role in the management of these symptoms.

Ocular Manifestations of Venomous Snake Bite over a One-year Period in a Tertiary Care Hospital
Praveen Kumar K V,Praveen Kumar S,Nirupama Kasturi,Shashi Ahuja 대한안과학회 2015 Korean Journal of Ophthalmology Vol.29 No.4
Purpose: Ocular manifestations in snake-bite injuries are quite rare. However, the unusual presentations, diagnosis and their management can pose challenges when they present to the ophthalmologist. Early detection of these treatable conditions can prevent visual loss in these patients who are systemically unstable and are unaware of their ocular condition. To address this, a study was conducted with the aim of identifying the various ocular manifestations of snake bite in a tertiary care center. Methods: This is a one-year institute-based prospective study report of 12 snake bite victims admitted to a tertiary hospital with ocular manifestations between June 2013 to June 2014, which provides data about the demographic characteristics, clinical profiles, ocular manifestations, and their outcomes. Results: Twelve cases of snake bite with ocular manifestations were included of which six were viper bites, three were cobra bites and three were unknown bites. Six patients presented with bilateral acute angle closure glaucoma (50%), two patients had anterior uveitis (16.6%) of which one patient had concomitant optic neuritis. One patient had exudative retinal detachment (8.3%), one patient had thrombocytopenia with subconjunctival hemorrhage (8.3%) and two patients had external ophthalmoplegia (16.6%). Conclusions: Bilateral angle closure glaucoma was the most common ocular manifestation followed by anterior uveitis and external ophthalmoplegia. Snake bite can result in significant ocular morbidity in a majority of patients but spontaneous recovery with anti-snake venom, steroids and conservative management results in good visual prognosis.
