Background:
Presence of subretinal abscess in endogenous endophthalmitis indicates a more severe form of infection. Available reports indicate variable response to standard treatment with systemic, intravitreal pharmacotherapy and vitreous surgery. There are no reports citing the possible role of intralesional antibiotic therapy in managing subretinal abscess.
Case presentation:
A 30 year old lady presented with features of endogenous endophthalmitis and subretinal abscess. Presenting vision was finger counting close to face. Despite prompt initiation of systemic antibiotics and intravitreal injection, no response was noted. 25G pars plana vitrectomy was performed along with injection of vancomycin directly into the subretinal abscess, using a 41G needle. Postoperative course was uneventful and the abscess showed signs of rapid resolution. Visual acuity improved to 6/24.
Conclusion:
Intralesional pharmacotherapy may be safe and effective in the treatment of subretinal abscess associated with endogenous endophthalmitis.
