Abstract

Purpose To evaluate the clinical effectiveness of diode laser transcleral cyclophotocoagulation in the treatment of glaucoma after intravitreal silicone oil injection for complicated retinal detachments Methods In a series of 301 patients who underwent pars plana vitrectomy with silicone oil injection, 62 patients (prevalence 18.5%) had postoperative glaucoma and in 7 cases the glaucoma was refractory to all treatments (all these eyes had silicone oil removal within three months from vltreoretinal surgery). In these 7 cases (6 seeing eyes and 1 blind and painful eye) we performed a transcleral cyclophotocoagulation using a diode laser (IRIS Medical Oculight Photocoagulator). All eyes were treated with 16 spots over 360°, 1 5mm posterior to the limbus, using 2 W of energy for 2 seconds. Mean follow up period was 11.5 ±7.89 months, 5 cases had only 1 treatment and 2 cases had 2 treatments. The mean pre and post-treatment lOPs were 32 ±3.4 and 14.8 ±6.6 mmHg respectively (p=0.000). In 5 cases (71.4%) an IOP <21 mmHg was reached and in the blind eye the remission of pain was obtained. No major complications were observed. Conclusions The study suggests that diode laser transcleral cyclophotocoagulation is a non invasive, safe and effective technique in the management of glaucoma after intravitreal silicone oil injection.
