[Estimation of the efficacy of deep sclerectomy in glaucoma surgery. One-year follow-up]

To evaluate the efficacy of deep sclerectomy in the surgical treatment of glaucoma one year after surgery.

53 eyes of 43 patients (26 male, 27 female) with medically uncontrolled glaucoma of various types, were treated with deep sclerectomy surgery.

The mean postoperative intraocular pressure (IOP) was 18.19 S.D. 5.22 mmHg., and the mean preoperative IOP was 26.66 S.D. 5.93 mmHg. We observed a statistically significant reduction in the IOP (p<0.05). Our success criteria were IOP lower than 21 mmHg with or without associated hypotensive medications, no advance in glaucomatous visual field defects and no advance in optic nerve cupping. This was achieved in 88.68% of the cases at 12 months follow-up.

Deep sclerectomy is an efficient technique to control IOP, with few early post-operative complications.
