Abstract

• Purpose: To report a large consecutive case series of patients who developed delayed-onset and acute-onset endophthalmitis after cataract surgery. • Design: Retrospective consecutive case series. • Methods: The current study is a retrospective consecutive case series of patients treated between January 2000 and December 2009 for culture-proven endophthalmitis after cataract surgery. The study defined 2 groups after cataract surgery: acute-onset endophthalmitis (≤6 weeks after surgery) and delayed-onset endophthalmitis (>6 weeks after surgery). • Results: A total of 118 patients met study criteria; cases included 26 delayed-onset cases and 92 acute-onset cases. The following clinical features and outcomes occurred in delayed- vs acute-onset cases: 1) the presenting visual acuity was ≤5/200 in 31% vs 89%; 2) hypopyon was found in 46% vs 80%; 3) the most frequent isolate was Propionibacterium acnes (11/26) vs coagulase-negative Staphylococcus (57/92); and 4) patients with the most frequent isolate achieved a visual outcome of ≥20/100 in 91% vs 56%. In delayed-onset cases, the intraocular lens was removed or exchanged in 19 of 26 cases (73%). Of these 19 cases, 13 achieved a visual outcome of ≥20/100. • Conclusions: Patients with delayed-onset endophthalmitis generally presented with better initial visual acuities, had a lower frequency of hypopyon, and had better visual outcomes compared to acute-onset patients. Propionibacterium acnes and coagulase-negative Staphylococcus species were the most common organisms cultured in delayed- and acute-onset categories, respectively, and were associated with the best visual acuity outcomes in each group.
