[[Trabeculectomy in Madagascar. Retrospective study over 3 years].

This study reports the results of the evolution of ocular pressure, glaucoma excavation and complications after trabeculectomy particularly cataracts observed in 47 cases of chronic glaucoma. Our chronic glaucomas are frequent in male with an average of age of 60,5 years. Normalisation of ocular tension has been obtained in 87.23% of cases. However in 10.53% of cases, an adjuvant medical treatment has been necessary. Ocular pressure figure raised up progressively after trabeculectomy to reach some limit from which it remains stable. The best ocular pressure control has been observed first in glaucoma with opened angle, then in post traumatic glaucoma. Visual acuteness was improved in 20.27% of cases. Trabeculectomy has involved a relief, a disparition of pain in all the cases. The main late complication observed is opacification of eye lens in patients aged more than 70 years old.
