title: Ocular toxicity caused by toad venom.
abstract: OBJECTIVE
  To report a case of ocular toxicity caused by toad venom.
  
  
  METHODS
  Observational case report.
  
  
  RESULTS
  A 31-year-old man came to our clinic complaining of burning pain, photophobia, and blurred vision in both eyes. He reported that an hour earlier he had been handling a toad (Bufo bufo). It ejected a liquid from its back that splashed on the patient's face and made him rub his eyes. Corrected visual acuity was 20/50 in the right eye and 20/40 in the left eye. Slit-lamp microscopy revealed mild chemosis and stromal corneal edema with Descemet folds in both eyes. Intraocular pressure (IOP) was 9 mm Hg in both eyes. Posterior segment examination was normal. Topical dexamethasone every 4 hours and cycloplegic 3 times a day were prescribed. Forty-eight hours later, corneal edema and conjunctival chemosis had resolved, and IOP was 18 mm Hg.
  
  
  CONCLUSIONS
  Ocular toxicity secondary to toad venom may cause corneal edema and low IOP that resolve without specific treatment in a short period.
