Fig. 1. Representative courses of severe, avirulent, and chronic endophthalmitis. Data represent composite findings from experimental and clinical Staphylococcus epidermidis, Staphylococcus aureus, Enterococcus faecalis, Bacillus cereus, and Propionibacterium acnes endophthalmitis. The kinetics of pathologic parameters (bacterial growth, retinal response, and inflammatory cell influx) are shown relative to arbitrarily chosen theoretical maximums rather than absolute measures of each parameter. Top arrows represent the initiation of treatment, based on clinical recommendations.
