Purpose To evaluate the role of micropulse diode laser trabeculoplasty (MDLT) in the treatment of secondary glaucoma due to intravitreal injection of corticosteroid. Methods Five consecutives patients previously treated with intravitreal triamcinolone (4mg) for refractory diabetic macular edema developed secondary glaucoma in the treated eye. Each eye underwent 360° micropulse diode laser trabeculoplasty (2000 mw power, 200 msec duration, 15% duty cicle, 300 µm diameter per spot). Patients were followed at 1, 7, 15, 28 days and monthly for 12 months. Results Mean age of the patients was 56 ± 2 years. Mean baseline intraocular pressure (IOP) was 30 ± 3 mmHg. IOP significantly decreased at 7 days post operative (19 ± 4 mmHg; p < 0.001) and maintained at normal level in 3 of 5 eyes. After 28 days two eyes needed retreatment and IOP maintained normal in one eye during follow up. No pain or side effect was documented. Conclusion Secondary glaucoma due to intravitreal injection of corticosteroid may be safely treated with micropulse diode laser trabeculoplasty.
