Abstract
Purpose: To analyze the effect of presence with or absent of retinopathy of prematurity (ROP) and its stage, birth weight, conceptual age and associated diseases on the axial length of premature infants' eye. Methods: A total of 102 eyes of 51 premature infants less than 36 weeks of conceptual age were evaluated in this study. Fundus examination for ROP and axial length measurement were conducted at 40, 52 and 64 weeks of postconceptual age. The medical records were reviewed retrospectively. Independent t-test analysis, simple regression analysis, and one-way ANOVA were performed to assess the influence of each factor on axial length. Results: The mean axial length at 40, 52 and 64 weeks were 17.35, 18.80 and 19.78 mm, respectively. The mean axial length with and without ROP at 40 weeks were 17.10 mm and 17.54 mm, respectively, which were statistically significant (p=0.000). There was a significant decrease in axial length at 40 weeks in the higher ROP stage (p
