Postoperative endophthalmitis due to : First reported case of acute and virulent presentation from a tertiary eye care center in South India.

A 60-year-old male presented with pain and decreased vision 3 weeks following uneventful intracapsular cataract extraction with anterior vitrectomy for subluxated cataract. A diagnosis of acute endophthalmitis was made based on clinical and ultrasound features. Patient improved only after undergoing pars plana vitrectomies twice and repeated intravitreal antibiotic-steroid injections. Vitreous aspirate revealed Gram-negative bacillus identified as Pseudomonas luteola on culture. Patient returned with a retinal detachment at first follow-up which was treated with vitrectomy, endolaser, and silicone oil tamponade. To the best of our knowledge, this is the first case of P. luteola causing acute onset, virulent endophthalmitis reported in literature.
