Etiology and diagnosis of fungal postoperative endophthalmitis.

Delayed infections after ocular surgery (especially cataract) are usually due to saprophytic contaminant fungi of relatively low pathogeneicity. About 20 different varieties of fungi have been cultured from such eyes. Thus, as far as the eye is concerned, there is no such thing as a harmless, benign fungus. Mycotic postoperative endophthalmitis is a distinct entity with a typical clinical picture, easily diagnosed once learned. Laboratory tests are often positive. Since the visual result is poor even if the eye is saved, prevention and early recognition are our primary concerns. In this regard, a recent episode of 12 infections from contaminated intraocular lens neutralizing solutions as well as other sporadic instances of fungal infection after lens implantation must be noted.
