[Tonometric course after trabeculectomy. Apropos of 105 cases at the Lomé UHC]. / Evolution tonométrique après trabéculectomie. A propos de 105 cas observés au CHU de Lomé.

ABSTRACT

BACKGROUND: This study has been conducted in order to assess tonometric changes after trabeculectomies without antimetabolites in primary open angle glaucoma. MATERIAL AND METHODS: One hundred and five eyes (105) in 64 patients with complicated open angle glaucoma with drug-resistant intraocular pressure or presenting disease progression were followed for 36 months. RESULTS: The mean intraocular pressure before surgery was 32.24 mmHg. Success rate (IOP < 21 MMhG without additional medical treatment) assessed with the Kaplan-Meier method was 64% at 12 months, 60% at 24 months and 56% at 36 months. CONCLUSION: In our experience, many factors including the cost of medical treatment are discussed before the surgery. Our success rate probability was average. Antimetabolites and medical additional treatment are needed for improvement.
