Clinical Trial Summary

A prospective, randomized comparative study on adult patients with synechial angle closure glaucoma.

Description:

Patients were randomized into two groups: group A : patients will undergo two site phacoemulfication combined with trabeculectomy Group B with Phacoemulsification combined with ab-externo trabeculotomy. Preoperative assessments including full ophthalmic examination, anterior segment Optical Coherence Tomography (OCT) of the angle , endothelial cell count , visual fiend Perimetry and Biometry. Patients were followed up: first day, first week and every two months for 6 month. We will compare adverse effects and outcomes in both groups.
