The most common types of glaucoma were neovascular and glaucoma secondary to silicone oil. Surgical success was achieved in more than 70% of patients and the mean IOP value decreased from 37.7 mmHg preoperatively to 19.5 mmHg after six months of follow-up with statistical significance. The average number of hypotensive drugs used by impaired patients went from 2.73 before surgery to 1.93 after 180 days. Complications occurred in less than 10% of patients.
