Purpose
To describe how vitreoretinal specialists have incorporated the Endophthalmitis Vitrectomy Study (EVS) findings into current practice, to highlight divergences from the EVS recommendations, and address the role of microbial culture in guiding additional treatments.
Methods
This is a cross-sectional survey of vitreoretinal specialists regarding indications used for performing a pars plana vitrectomy (PPV), selection of antibiotics for treatment, utilization of cultures, and treatment strategies for treatment-refractory patients with bacterial endophthalmitis.
Results
Of 681 physicians contacted, 149 (21.9%) responded. For patients with visual acuity of light perception or less, 75% of respondents utilized PPV. Intravitreal vancomycin and ceftazidime were used by 100% and 96% of participants respectively. Vitreal cultures were obtained more than 50% of the time by 86.5% of participants, and were used to influence retreatment less than 50% of the time by 77.8% of respondents. For patients with worsening clinical signs 48 hours after initial treatment, 69.8% of participants performed PPV with intravitreal antibiotics.
Conclusions
Although most respondents followed the EVS guidelines, a minority deviated, and the majority generalized their strategy to other forms of endophthalmitis. There is significant variation in retreatment strategies, and while cultures are frequently obtained to help guide these treatments, they are utilized infrequently.
