Corneal Endothelium Cell Loss after Ahmed and Baerveldt Glaucoma Drainage Device Implantation: A Systematic Review and Meta-analysis

Overall, implantation of a GDD leads to clinically relevant corneal endothelial cell loss. ECD loss may be more pronounced in Asians compared to Caucasians. No difference in ECD loss was observed between the two GDD types GDD. The existing evidence is characterized by heterogeneity, and further high-quality randomized controlled trials are necessary to establish definitive estimates.
