Aim: Endophthalmitis remains one of the most dreaded complications of modern cataract surgery. Its nationwide incidence has been estimated but published data on accurate incidence at regional level is scarce. This audit examines incidence and visual outcome of endophthalmitis from a single eye department in Scotland over a 7 year period. Findings are compared with those from other series.
Methods: A retrospective consecutive audit of all cases of acute endophthalmitis treated between 1st January 2000 and 31st December 2006 at the Southern General Hospital in Glasgow was undertaken. Details of each case in relation to presentation, treatment and outcome of endophthalmitis were recorded. Cross-tabulations were performed to identify prognostic factors of visual outcome.
Results: Twenty-five patients were treated for endophthalmitis over the audit period. The incidence of endophthalmitis was 0.20% (95% confidence interval, 0.10-0.30%). There were 12 (48%) culture positive cases with coagulase negative staphylococcus accounting for 58%. After treatment, sixteen patients (64%) achieved driving standard vision or better. Poor vision at presentation and streptococcal endophthalmitis were associated with poor visual outcome.
Conclusion: The incidence of endophthalmitis in this series is comparable to larger studies suggesting that accepted benchmarks, despite being estimates, reflect UK practice. Visual outcome, with treatment, can be favourable in a significant proportion of patients.
