The aim of this study is to develop a non-invasive predictive test for the function of the distal outflow tract after ab interno trabeculectomy for open angle glaucoma. We hypothesize that the ocular pressure drop and outflow change after preoperative trabeculectomy may predict the success of ab interno trabeculectomy. The results of this study should allow trabeculopuncture to be used to select the most appropriate procedure for the individual patient.
