Is 20/20 visual outcome a reality in rubella cataract? - Prognostic factors in children with cataract associated with congenital rubella syndrome.

Purpose: The aim of this study ws to evaluate prognostic factors associated with final visual outcome in patients with congenital cataract associated with congenital rubella syndrome. Methods: A prospective interventional analysis of preoperative systemic and ocular features of 56 eyes of 28 seropositive infants of less than 12 months presenting to us with bilateral cataract was performed. All infants were surgically treated with cataract extraction, posterior capsulorhexis, and anterior vitrectomy followed by visual rehabilitation. Intraocular lens implantation was done in children after 2 years of age. Outcome data were collected till children reached the fifth chronological age. Chi-square test was used as a test of significance for qualitative data. Results: Of the 56 eyes, 44.6% eyes had vision better than 20/60. Important preoperative factors related to poor visual prognosis were morphology of cataract (P = 0.004), microphthalmos (P
