Effect of Trabeculotomy on Corneal Endothelial Cell Loss in Cases of After Penetrating-Keratoplasty Glaucoma

Purpose: The aim of this study was to evaluate the effect of trabeculotomy (TLO) on glaucoma and endothelial cell loss after penetrating keratoplasty (PK). Methods: A retrospective study was conducted on consecutive patients who underwent PK and in whom more than 24 months of follow-up was available. Patients were categorized into the PK+TLO group [ie, TLO for post-PK glaucoma (n = 10)] and the PK group [PK alone (n = 73)]. Intraocular pressure (IOP) was evaluated during each follow-up examination. Central corneal endothelium images were obtained and analyzed to determine corneal endothelial cell (CEC) density. Results: The mean duration period from original PK to TLO for secondary glaucoma was 25.5 ± 34.9 months in the PK+TLO group. Mean preoperative IOP in the PK+TLO group was 35.8 mm Hg, and decreased to 17.5 mm Hg at 24 months postoperative (P
