Ultrasound biomicroscopy fin­dings in the area of previous surgical intervention in refractory glaucoma patients under topical ocular hypotensive therapy

Abstract

In contrast to well controlled POAG patients, target values of IOP were not achieved in refractory POAG patients with either of the topical therapeutic measures. Moreover, intrascleral cavity and filtering bleb heights in these patients were reliably low (p ≤ 0.01), as confirmed by UBM analysis of the area of surgical intervention.
