Children with neurological conditions such as cerebral visualimpairment (CVI) are likely to have visual concerns as well as developmental delays inareas such as motor, cognition and speech. Through this study, we aim to determine thecorrelation between vision loss and the overall development of children with CVI.Methods : A prospective cross-sectional study was conducted on children with CVIvisiting a paediatric neurology unit in India. Grating acuity (Teller Acuity Cards), contrastsensitivity (Ohio Contrast Cards), functional vision (Lantzy’s CVI range; phase 1=buildingvisual behaviour, phase 2=integrating vision with functions, phase 3=resolution of CVIcharacteristics) and developmental quotient (DQ) (Denver Developmental ScreeningTest-II) were assessed.Results : Forty-seven children (males: 35) with CVI were included with a meanchronological age of 2.9±1.7 years (range= 9 months to 6.8 years). The mean binoculargrating acuity was 1.35±0.67 logMAR (range=2.27 to 0.37 logMAR) and mean binocularcontrast sensitivity was 0.49±0.56 logCS (range=0.0 to 1.66 logCS). Grating acuity(r=-0.36, p=0.01), contrast sensitivity (r=0.41, p<0.01) and functional vision score (r=0.5,p<0.01) were significantly and moderately correlated with DQ. Using linear mixed model(age adjusted), the outcome parameters of grating acuity, contrast sensitivity and DQwere compared to the CVI phases. Significant difference was noted across the 3 phases ofCVI for grating acuity (p<0.01). There was no significant difference between phase 1 and 2for contrast sensitivity and DQ (p=0.09), however phase 3 showed significant differencewhen compared with other two phases (p<0.01).Conclusions : Vision parameters correlate with DQ in children with CVI. Although thereis no separate vision domain in most developmental screening tools, psychologists couldconsider referring children particularly with lower DQs for vision assessment. Eye-carepersonnel should also ensure providing referrals to therapists for child’s overalldevelopment particularly during the early years. The results do not establish any2/2causation between the 2 parameters (visual vs. DQ) and can be further explored bystudying the DQs of children having ocular visual impairment and no additionaldevelopmental delays.This abstract was presented at the 2022 ARVO Annual Meeting, held in Denver, CO, May1-4, 2022, and virtually.This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.Advertisement
