2 Consequences of Childhood VI Social Emotional Physical Educational Economical Quality of Life

3 Consequences of Childhood VI Unilateral congenital cataract associated with delayed motor functioning at 4.5 years - may adversely affect social and academic functioning* If unilateral, risk of 5-year incident VI in betterseeing eye (RR = 2.7 X) *Celano et al. Dev Med Child Neurol in press (from Infant Aphakia Trial)

4 Leading Causes of Childhood Blindness in US Cortical visual impairment Optic nerve hypoplasia Retinopathy of prematurity (ROP) risk if minority, low SES, low birth weight Kong et al. J AAPOS 2012;16:

5 Retinopathy of Prematurity: US Incidence Overall = 0.17% Premature infants in NICU = 7.35% If >28 days NICU = 15.5% Lad et al. Am J Ophthalmol 2009;148:

6 Leading Causes of Visual Impairment Infants, Toddlers, Preschoolers Amblyopia Refractive Error Strabismus The BIG THREE

7 Amblyopia Reduced best-corrected VA with amblyogenic factor in healthy eye(s) Abnormal visual experience interferes with normal development of visual pathways - impaired form vision Most common cause of vision loss in children
