[Visual prognosis factors in congenital cataract].

PURPOSE: Study of different factors which can change the visual prognosis in congenital cataract.

METHODS

One hundred seventy eyes of 100 children with congenital cataract are operated by extracapsular cataract extraction with limbic incision. Posterior rhexis and anterior vitrectomy were associated in children under 2 years. Implantation was used in 42%, contact lens in 8%. Other cases were corrected by glasses. The prognostic factors studied were: uni- or bilaterality, partial or complete aspect of cataract, age of apparition and management, and association with other malformations.

RESULTS

Only 9 eyes out of 30 with unilateral congenital cataracts had visual acuity > or = 2/10; 44.4% of bilateral cataracts had visual acuity > or = 2/10; The best visual acuity was noted in progressive and partial cataract without associated malformations.
