Pseudomonas Endophthalmitis: an analysis of fifteen cases.
Pak J Surg Jan ;24(2):113-6.

Objective: To analyze the incidence of endophthalmitis caused by Pseudomonas aeruginosa after cataract surgery and the treatment outcome. Design & Duration: Retrospective case series from January 2004 to December 2006. Setting: Department of Ophthalmology, Unit I, Civil Hospital, Karachi. Patients: All cases who developed Pseudomonas endopthalmitis after cataract extraction with intraocular lens (IOL) lens implant (n=375) during the study period. Methodology: The medical records of all patients who were treated for Pseudomonas aeruginosa culture-proven endophthalmitis were reviewed. Results: Out of the total 375 cases 15(4%) developed Pseudomonas endopthalmitis. There were 11(73.33%) male and four (26.66%) female patients with a median age of 56 years (range 52-60 years). Symptoms appeared between the 1st and 4th postop. day, and the time interval between surgery and confirmation of Pseudomonas endophthalmitis ranged from 3-6 days. The clinical features at presentation included pain, increased congestion, flare, cells and hypopyon. The visual acuity (VA) at presentation i.e. pre-treatment was from perception of light (PL) & projection of rays (PR) in six cases, hand movement (HM) in four and finger counting (FC) in five cases. Six weeks after treatment the VA improved to 5/60 in seven and 6/36-6/9 in three patients; five cases had faulty projection and deteriorated to no perception of light (NPL) at six weeks post-treatment. Conclusion: There is no relationship with age and gender, but the time interval between surgery, appearance and duration of symptoms and confirmation of Pseudomonas endophthalmitis are important. Better visual acuity resulted when patients presented early, had early diagnosis, and prompt and proper treatment.
