Purpose: To determine the spectrum, clinical profile and risk factors for poor visual outcome in patients of post cataract surgery endophthalmitis.

Methods: Data from 124 eyes were analysed. Various clinical and microbiological parameters were evaluated and risk factors for unfavourable outcome identified.


Results: The mean age of the patients was 59.50 +/- 13.75 years; 60.5% were males. The median surgery-symptom interval was 7 days (mean 15.81 +/- 24.01) and the medium symptom-presentation interval 7.5 days (mean 14.19 +/- 19.13). Corneal infiltrates were seen in 29%, hypopyon in 62 (50%). Smear positivity was 52.5% and culture positivity 38%. Equivocal microbiological positivity was seen in 22 (18%), bacterial 12 (10%), fungal 27 (21.5%), polymicrobial 8 (6.5%) and negative 55 (44%). 20% eyes had total loss of vision at last follow-up. Poor visual acuity at presentation, presence of intraocular lens, shorter surgery-symptom interval, corneal and surgical wound infiltrates, loss of red reflex, microbiological positivity of the vitreous tap and systemic diabetes mellitus were significant risk factors for unfavourable outcome.

Conclusion: Our data highlights a low culture positivity and a predominance of fungal pathogens as a cause of post cataract surgery endophthalmitis. The visual outcome in these patients is still dismal and better treatment strategies should be evolved keeping in mind the microbiological spectrum. The risk factors identified may be helpful in prognosticating the outcome in such patients.
