• PurposeFive-year prospective data on children enrolled in the Infant Aphakia Treatment Study (IATS) provided an opportunity to explore ocular and systemic associations in patients with a unilateral congenital cataract.MethodsInfants <7 months of age with a unilateral cataract were eligible for IATS screening. We reviewed data pertaining to the exclusion of patients as well as data collected on standardized study forms used at any time for documentation of ocular or systemic disorders.ResultsOverall, 227 infants were referred for possible enrollment. Of these, 10 had insignificant cataracts and 32 refused to participate. Of those excluded, 3 were premature, 27 had significant ocular disease (usually persistent fetal vasculature (PFV) or corneal diameter <9 mm), and 4 had systemic disorders. An additional 26 were excluded at the time of the first EUA, most often because of PFV or variants thereof. On follow-up, in the 114 enrolled patients, the following disorders were diagnosed: Stickler syndrome (1), mitochondrial disease (1), autism (1), and presumed congenital rubella syndrome (1). No patient developed a cataract in the fellow eye.DiscussionSome conditions that can feature unilateral cataracts are diagnosed at birth or very early in life, but others may be diagnosed at varying periods thereafter. PFV and its variants are the most common associated ocular findings in about a quarter of cases of unilateral congenital cataracts.ConclusionAlthough patients with a unilateral cataract may have significant associated abnormalities in the affected eye, most commonly PFV and its variants, the prevalence of associated significant systemic disease is quite low.
