[Tonometric course after trabeculectomy. Apropos of 105 cases at the Lomé UHC].

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.
