[Results of early treatment of congenital strabismus].

The authors analyse the results obtained after very early treatment of Esotropia in 38 children. These children were divided into 4 groups according to their age at the time of treatment. At the age of 30 months, they studied binocular vision, manifest latent nystagmus (NML) and dissociated vertical deviation (DVD). In groups 1 and 2, treatment was instituted before the age of 6 weeks (13 children) no DVD was noted, only one NML and 11 children have binocular vision. In groups 3 and 4, treatment was instituted after the age of 3 months (25 children) 4 cases of DVD and 10 of NML are noted, and only 9 children have binocular vision. In case of congenital esotropia, the authors recommend treatment before 2 months old to obtain a possibility of binocular vision and to decrease the risk of NML and DVD.
