Abstract:

Objective To analyse the outcomes of selective laser trabeculoplasty (SLT) in treatment of secondary glaucoma after intravitreal silicone oil injection. Methods Eighteen patients (18 eyes) with secondary glaucoma after intravitreal silicone oil injection were selected, and SLT was performed with 360° of the trabecular meshwork at 100 points. All patients were followed up, and complications, intraocular pressure and drug usage were observed. Results After SLT treatment, mild pain occurred in 4 eyes (22.2%), mild conjunctival hyperemia in 8 eyes (44.4%), anterior uveitis in 7 eyes (38.9%), anterior chamber bleeding in 1 eye (5.56%), and transient intraocular pressure spike in 3 eyes (16.7%). The mean intraocular pressure decreased from (25.56±3.09) mmHg before treatment to (20.17±2.57) mmHg after treatment (t=8.581, P=0.000 1). The number of drugs for intraocular pressure control also decreased from 2.167±0.514 to 1.333±0.840 （t=4.499，P=0.000 3）. Conclusion SLT is a safe and effective option in treatment of patients with secondary glaucoma after intravitreal silicone oil injection.
