RESUMEN
PURPOSE: Snake bite to the eye is a rare event. Most cases reported in the literature are due to boa constrictor bites. This is a rare case of snake bite from a common adder (Vipera berus) to the ocular adnexa along with a retained intraorbital tooth. METHOD: A 57-year-old man presented with a history of being bitten by an adder in the left eye upper lid 12 days previously while bending down to pick up a log at his farm. He developed a firm, tender lump in the medial part of his left upper eyelid. RESULT: A CT scan revealed an extraconal curved calcific dense foreign body, about 5 mm in length consistent with adder's tooth in the superomedial part of left orbit. CONCLUSION: There are few reports of adder bites on face, ear and neck. We report a rare case of adder bite on eyelid along with retained intraorbital fangs and its clinical outcome.
