Abstract

Abstract : Background/aim: Previous studies have revealed various subnormal visual functions in prematurely born children. The present study aimed to determine the retinal macular thickness in prematurely born children and compare with children born at term. Methods: The eyes of 65 prematurely born children aged 5–16 years were examined with Stratus optical coherence tomography (OCT) 3, and the results were compared with those of 55 children born at term. The retinal macular thickness in the nine EDTRS macular areas (A1–A9), the foveal minimum and the total macular volume were determined. Results: The central macular thickness (A1 and foveal minimum) was significantly thicker in the prematurely born children than in those born at term. There was no correlation between macular thickness and visual acuity or refraction. Children with previous retinopathy of prematurity (ROP) had significantly thicker central maculae than those without it. Prematurely born children without previous ROP had significantly thicker central maculae than the control group. Multiple regression analyses showed that gestational age at birth was the only risk factor for a thick central macula. Conclusion: Prematurely born children had thicker central maculae than those born at term. Regardless of ROP, the degree of prematurity was the most important risk factor for abnormal foveal development.
