Brief summary

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

Detailed 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.

Interventions

PROCEDUREPhacoemulsification combined with trabeculectomy

Patients with chronic angle closure glaucoma assigned to this group will have fornex based trabeculectomy at superior limbus and then phacoemulsification via temporal incision

PROCEDUREPhacoemulsificaiton combined with ab-externo trabeculotomy

Patients with chronic angle closure glaucoma assigned to this group will have Deep Sclerectomy with ab externo trabeculotomy at superior limbus and then phacoemulsification via temporal incision
