Background: The aim of this study was to investigate a possible influence of body mass index (BMI) to the outcome of trabectome surgery.

Methods: 131 eyes with primary open angle glaucoma, myopia-associated glaucoma and pseudoexfoliation glaucoma were included into this retrospective study. The data were extracted from the Freiburg trabectome database from June 2009 to April 2013. We fitted a Cox proportional hazards model in order to assess the influence of the BMI on trabectome outcome.

Results: The absolute success after trabectome surgery (20 % pressure reduction without anti-glaucomatous medication) was statistically significantly better in the group with BMI > 25 kg/m(2) (p = 0.047). No statistically significant effect was observed for relative success or the rate of re-operation respectively.

Conclusion: In our patient cohort of 131 eyes, a high BMI was associated with a reduced success, as long as an absolute success is required. No difference is seen if additional anti-glaucomatous medication is acceptable (relative success).
