Abstract: :
Purpose: We evaluated the clinical history, outcome and identified endophthalmitis pathogens of patients referred to and from the Ophthalmology Institute "Conde de Valenciana" in Mexico City from March 2002 to August 2003. Methods: 50 eyes with endophthalmitis were managed with endophthalmitis vitrectomy study group guidelines and screened with polymerase chain reaction, gram stain and culture. Results: Common causes facoemulsification 24%, trauma 18%, extracapsular cataract extraction 16% and Ahmed valve 8%. Hospital incidence in cataract surgery 0.28% (12 of 4,214 cases). Polymerase chain reaction identified 90% (gram + 82%, gram –14%, fungi 4%), gram stain 34%, culture 42%. Initial visual acuity 40% light perception 60% hand motion or better. Final visual acuity 34% no light perception, 34% light perception to 2/200, 16% 5/200 to 20/200 and 16% 20/80 to 20/25. Conclusions: Polymerase chain reaction helped to identify more endophthalmitis pathogens and may determine proper management.
