Further observations on the diagnosis, etiology, and treatment of endophthalmitis.

This report of 54 suspected cases of endophthalmitis emphasizes the following findings: 1. That vitreous aspiration is more sensitive in making a culture proven diagnosis than anterior chamber paracentesis. 2. That Staphylococcus epidermidis is a much more common cause of endophthalmitis than previously apprediated. 3. That intraocular antibiotics in the recommended dosage, are reasonably safe clinically and add a new dimension to the treatment of endophthalmitis.
