[Estimation of the efficacy of deep sclerectomy in glaucoma surgery. One-year follow-up]. / Estimación de la eficacia de la esclerectomía profunda no perforante en el tratamiento quirúrgico del glaucoma al año de la cirugía.

PURPOSE: To evaluate the efficacy of deep sclerectomy in the surgical treatment of glaucoma one year after surgery. METHODS: 53 eyes of 43 patients (26 male, 27 female) with medically uncontrolled glaucoma of various types, were treated with deep sclerectomy surgery. RESULTS: 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. CONCLUSIONS: Deep sclerectomy is an efficient technique to control IOP, with few early post-operative complications.

[Treatment of conjunctival intraepithelial neoplasia with topical mitomycin C 0.02%]. / Tratamiento de las neoplasias conjuntivales intraepiteliales con colirio de mitomicina C al 0,02%

PURPOSE: To evaluate the efficacy of topical mitomycin C (MMC) 0.02% in treating conjunctival intraepithelial neoplasia (CIN). METHODS: Three patients with CIN were treated with topical MMC 0.02%. Our follow-up period was twelve months (range 8-18 months). RESULTS: CIN was resolved in all three cases without modifying the normal corneal and conjunctival architecture. CONCLUSIONS: Topical MMC 0.02% four times daily during two weeks is a useful alternative tool for the surgical management of CIN.
