PURPOSE: To report a large consecutive case series of @entity1 who developed delayed-onset and acute-onset @entity3225 after @entity231 surgery. DESIGN: Retrospective consecutive case series. METHODS: The current study is a retrospective consecutive case series of @entity1 treated between January 2000 and December 2009 for culture-proven @entity3225 after @entity231 surgery. The study defined 2 groups after @entity231 surgery: acute-onset @entity3225 ( <=6 weeks after surgery) and delayed-onset @entity3225 (>6 weeks after surgery). RESULTS: A total of 118 @entity1 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 @entity5478 (11/26) vs coagulase-negative Staphylococcus (57/92); and 4) @entity1 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: @entity1 with delayed-onset @entity3225 generally presented with better initial visual acuities, had a lower frequency of hypopyon, and had better visual outcomes compared to acute-onset @entity1 . @entity5478 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.
