[Etiology of endophthalmitis]

Sixty p. cent of endophthalmitis were seen after recent ocular surgery. Another 14% were seen after surgery performed some years before. Non perforating trauma were responsible for 9.5%, and another 9.5% were seen complicating old ocular lesions by chemical, mechanical or infectious agents. Only in 7% the etiology was endogenous in one case general sepsis by meningococci, in another case, mycotic infection after prolonged systemic cortisone treatment, and one case in which endophthalmitis remained unexplained. Most cases complicating recent ocular surgery were seen after cataract extraction.
