To identify the risk factors, microbes, treatment modalities, and outcomes of patients with endophthalmitis associated with Baerveldt Glaucoma Drainage Devices (GDDs).
A non-comparative consecutive case series of patients at the Bascom Palmer Eye Institute diagnosed with endophthalmitis associated with Baerveldt GDDs between January 1, 1999 and July 31, 2011 was done.
9 patients were identified. The average time elapsed from GDD surgery to endophthalmitis was 20 months with a range of 1 week to 4 years. 2 patients grew Staphylococcus epidermidis. 2 patients grew Staphylococcus aureus. 2 patients grew Serratia marcescens. 1 patient grew Streptococcus sanguis. 1 patient grew both Proteus mirabilis and Staphylococcus warneri. 1 patient grew both Staphylococcus epidermidis and Mycobacterium fortuitum. All patients were injected with intravitreal vancomycin and ceftazidime at the time of infection. 5 of 9 patients had tube exposure. 2 patients underwent evisceration. 3 patients underwent tube removal. Median pre-infection visual acuity was 20/100 with a range of 20/50 to HM. Median post-infection visual acuity was 20/400 with a range of 20/60 to NLP. Average loss of vision was 3.4 lines with one patient progressing to LP and two patients to NLP.
Endophthalmitis associated with Baerveldt GDDs is uncommon. In the current study, tube exposure was a common risk factor for endophthalmitis. Infections were caused by a broad spectrum of microbes. Visual outcomes were generally poor.
