[Epidemiology of trachoma and vision disorders in central Viet Nam].

Cataract is the first blinding disease in VIETNAM. Its frequency was studied in Central VIETNAM. Trachoma and xerophthalmia are very common. The evaluation of the prevention program against blindness in Central Areas of VIETNAM is set up. The authors point out an important improvement of the situation. Nevertheless they stress the necessity of carrying on the anti-trachomatous and anti-xerophthalmic campaign. A higher number of cataract operations could be performed since a sufficient number of operating kits was allowed.
