Corneal sting by wasp is a relatively rare phenomenon. Wasp, bees and yellow jackets belong to Hymenoptera species of insects. A triad of mechanical, toxic and immunologic damage has been proposed to explain the spectrum of injuries from wasp stings.

Wasp venom is a complex mixture of toxic substances such as Phospholipase A, Phospholipase B, Apamine, Hyalouronidase, Mast cell degranulating peptide and Mastoparan peptide, which is implicated in direct mast cell degranulation leading to histamine release. A wide range of immunologically mediated ocular sequel have been described which include focal or diffuse corneal edema, bullous keratopathy, panuveitis, hyphema, anterior polar cataract, papillodema, lens subluxation and optic neuritis. The author hereby tends to report a case of Striate Keratitis following wasp sting, its expected pathogenesis, treatment and outcome.
