PURPOSE: The purpose of this study was to evaluate the influence of trabectome surgery on corneal endothelial cells by site. METHODS: Retrospective observational study. Trabectome surgeries were performed on 159 eyes of 132 adult Japanese patients. Corneal endothelial cells were measured at the center (C), inferior (I), nasal inferior (NI), nasal superior (NS), superior (S), temporal superior (TS), and temporal inferior (TI) sectors at <1 month preoperatively and 3, 6, 12, 24, and 36 months postoperatively, for changes in corneal endothelial cell density (ECD), coefficient of variation (CV), and incidence of hexagonal cells (6A). RESULTS: Mean preoperative ECD in all groups were 2401±451 (SD)  cells/mm (C), 2366±450 cells/mm (I), 2397±479 cells/mm (NI), 2476±554 cells/mm (NS), 2493±596 cells/mm (S), 2464±558 cells/mm (TS), and 2329±510 cells/mm (TI). The 12-month postoperative mean ECDs were 2344±480 cells/mm (C), 2312±469 cells/mm (I), 2325±536 cells/mm (NI), 2473±517 cells/mm (NS), 2438±607 cells/mm (S), 2227±578 cells/mm (TS), and 2193±523 cells/mm (TI). There was no change in ECD in all sectors before and after surgery. ECD decreased at the TS and TI in combination with cataract surgery (2620±430 and 2445±384 cells/mm) preoperatively to 2264±501 and 2216±477 cells/mm at 12 months postoperatively. CV and 6A did not change at all sites in all surgical procedures before and after surgery. CONCLUSIONS: Trabectome surgery involves minimal effects to corneal endothelial cells, although long-term prospective studies with greater sample sizes are necessary to confirm this conclusion.
