PURPOSE: To assess the efficiency and safety of MicroPulse® Transscleral Laser Therapy (TLT) in the management of silicone oil-induced glaucoma. METHODS: A prospective case series of 33 eyes with uncontrolled silicone oil-induced glaucoma was enrolled at the department of ophthalmology of Mohamed Taher Maamouri Hospital, Nabeul, Tunisia. Patients were treated with MicroPulse TLT using the IRIDEX Cyclo G6® Glaucoma Laser System with the MicroPulse P3® fiberoptic handheld probe. Patients underwent complete ophthalmologic examination during the 12-month follow-up period. RESULTS: The study included 33 eyes of 33 patients. The mean age was 50.39 years old. We included patients with silicone oil-induced glaucoma. Silicone oil tamponade was indicated for complicated rhegmatogenous retinal detachment in 22 cases, diabetic tractional retinal detachment in 10 cases, and post-traumatic retinal detachment in one case. Silicone oil was already removed before the procedure in 23 eyes. Silicone oil tamponade duration varied between 3 to 26 months. IOP measurements at enrolment, day 1, day 7, day 15, 1 month, 3 months, 6 months and 12 months was respectively 37.94±13.61, 19.03±10.98, 16.5±6.17, 19.45±9.73, 19.27±8.33, 19.39±9.52, 19.97±10.03 and 19.7±9.58▒mmHg. The percentage of IOP lowering was 45.38% at 6 months and 45% at 12 months. The success rate was 93.93% at 6 months remaining stable at 12 months. No major side effects were observed, in particular, no phthisis bulbi nor prolonged inflammation. There was no difference in IOP lowering between patients with silicone oil or those after silicone oil removal (P=0.99). CONCLUSION: MP-TLT was safe and effectively lowered intraocular pressure in uncontrolled silicone-oil induced glaucoma.
