Purpose: To report an unusual case of sterile versus bacterial endophthalmitis in a post cataract surgery wound leak Subject: A 58-year-old woman with a past eye medical history of LASIK underwent routine cataract extraction (CE) with lens implant of left eye and presented with a delayed, fulminant endophthalmitis OS on day 19 post CE or 3.5 days after the development of a post-op wound leak. Eye examination OS showed visual acuity (VA) of bare LP. Slit lamp examination revealed an edematous cornea with a 1mm hypopyon. A large amount of exudate filled the entire posterior segment.Results: Patient was treated with intravitreal vancomycin (1mg) and ceftazidime (2mg) and pars plana vitrectomy. Vitreal cultures were negative, but initial clinical presentation mimicked a virulent strep, staph, or pseudomonas endophthalmitis. Her postoperative course showed gradual improvement, reaching baseline VA of 20/30 OS with a normal eye exam.
Conclusion:Although culture-negative bacterial endophthalmitis is common, good visual outcomes with virulent bacteria is not. Fulminant culture-negative endophthalmitis with a good visual outcome may be due to a sterile toxic insult, a variation of TASS which we call Toxic Posterior Segment Syndrome (TPSS).
