Infectious endophthalmitis.

A clinical series of twenty-eight cases of suspected infectious endophthalmitis was reviewed. The combination of epidemiology and peroperative microscopy at the time of vitreous biopsy provided a useful indication of the pathogen involved. The visual prognosis was related to the virulence of the pathogen, and to the delay between recognition of symptoms or signs and treatment. It appears possible to predict high risk groups which warrant a high index of clinical suspicion and prompt diagnosis to enable early vitrectomy with injection of appropriate intraocular antibiotics.
