Evaluation of Visual Field Changes after Trabeculectomy in ‎Patients with Glaucoma

To evaluate visual field changes after trabeculectomy in patients with glaucoma.
In this retrospective study, 166 eyes of 166 patients with glaucoma (mean age 53.3±17.9), who underwent mitomycin C augmented trabeculectomy, were examined. The patients needed to have at least 3 reliable visual field before the surgery and 2 after the surgery. The data of biomicroscopic examination, intraocular pressure, visual field, best corrected visual acuity, and spherical correction of refractive error were extracted from their electronic data record. The results of this study showed changes in visual filed mean deviation as the main outcome measure. Secondary outcome measure was intraocular pressure, visual acuity, visual field pattern standard deviation, and visual field index.
The mean post-operative IOP (13±5 mmHg) significantly decreased from the baseline values (19±6 mmHg) (P Glaucoma is a progressive optic neuropathy that even persists after significant intraocular pressure reduction. This underlines the importance of examining the optic nerve and the field of vision after surgery.
