[Eyelid necrosis caused by an hymenopteran insect bite].

We report a case report of extensive eyelid necrosis caused by an insect bite. A 39-year-old man had suffered ocular trauma from a hymenopteran insect in Tunisia. The patient presented with eyelid necrosis. Eyelid necrosis mechanisms following insect bites are discussed and other causes of eyelid necrosis are presented. Eyelid necrosis, often caused by vasoconstrictive medications or animal venoms, notably hymenopteran insect bites, can result in substantial eyelid injury.
