The authors wish to report a case of bilateral acute anterior uveitis and optic disc edema following a hemotoxic snake bite, in order to highlight the concomitant occurrence of these conditions and the potential adverse effects of anti-snake venom (ASV). A 35-year-old male was bitten by a viper at seventeen thirty hours, and was started on ASV. Two days following treatment he experienced sudden onset redness and painful 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), posterior synechiae, sluggish and ill-sustained pupillary reaction, and hyperemic, edematous disc with blurred margins 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 oral prednisolone tapered over 3 weeks, after which VA OU improved, the AC showed no cells and flare and disc edema resolved. Uveitis and optic disc edema in snake bite can either be due to the direct toxic effects of the venom or the effect of ASV. Steroids have a beneficial role in the management of these symptoms.

PURPOSE: Snakebite is an emergency which causes local symptoms such as pain and edema around the bite. Systemic symptoms may also develop, such as dizziness or renal failure, and may even cause death. The purpose of this research was to assess the validity and safety of snakebite protocol for surgery when treating snakebite patients. MATERIALS AND METHODS: Retrospective research was performed on patients who were admitted after being treated at the emergency center from January 2008 to December 2012. When necessary, debridement was also performed, and 46 of 111 patients (41.4%) underwent debridement. Those who had received debridement without antivenom administration due to a positive skin reaction test were classified as group A, and group B received antivenom and delayed debridement. We reviewed the emergency and admission charts of the patients in each group and recorded and compared their age, sex, bite site, severity of local and general symptoms, time to receive antivenin, and complications. RESULTS: Of the ten patients (21.7%) in group A, two (66.6%) developed cellulites, and one of them experienced skin necrosis, resulting in a skin graft. In group B, there were 36 patients (78.2%), 19 (52.7%) of whom developed cellulitis. Skin necrosis occurred in two patients, and one of these patients received a skin graft. Compartment syndrome was found in one patient, and fasciotomy and a skin graft were performed. CONCLUSION: The treatment protocol implemented to treat snakebite patients admitted to the emergency center during this research was safely and properly followed during surgical treatment.
