Abstract

Objective: Primary objective to compare refractive changes and ocular biometrics between preterm and term infants. Secondary objective to find association of gestational age and birth weight to final refractive status of infants at 1 year of age.Method:Cohort study enrolling 90 infants with 45 corrected gestational age preterm and 45 term. Growth and ocular parameters recorded at birth, 3 months, 6 months and 1 year age.Results: Mean axial length of preterm infants was 15.84±0.84mm and terms was 16.84±0.43mm. The mean spherical equivalent among preterm and term were -0.6 D and +1.1D respectively.Conclusion: The preterm infants have more tendency to develop myopia which increases for first few months after birth whereas term infants tend to emmetropisation since birth.There is no significant difference in emmetropisation among preterm and term infants at 1 year of age. Among gestational age and birth weight, Birth weight is strongly associated with final refractive status at 1 year age.
