Abstract
Purpose: The aim of this study is to evaluate the associations between retinal vessel density and choroidal thickness of macula in pediatric myopic eyes, using optical coherence tomography angiograohy ( SS-OCTA) and its correlation with axial length.Setting: Participants were recruited in Tbilisi State Medical University, Department of Pediatric Eye Diseases and Caucasus Medical Centre.
Methods: 96 eyes of 48 subjects with myopia and 40 eyes of 20 age-matched, emmetropic volunteers (control group) were enrolled in this study. Myopia was defined as spherical equivalent
Results: The whole RVD (retinal vessele density) and parafovea RVD were significantly higher in controls than in the myopic subjects.(p
Conclusions: CONCLUSION. In conclusion, we found a significant relation between axial length; choroidal thickness and retinal vessel density of macula in myopic children using SS-OCT. There are many factors affecting the thickness of the choroid including age, axial length and spherical equivalent. We found statistical significant and negative correlation between choroidal thickness and age as well as axial length.There was statistical significance between choroidal thickness and sex as well as spherical equivalent but there was no correlation between them. Our results suggest that superficial retinal vessel density is decreased in the entire group of the myopic children compared to emmetropic subjects. Longitudinal observation of these young patients is needed to determine the relevance of the microvascular alterations in the future. In children, increasing axial myopia was associated with choroidal thickness of macula. These findings suggest that early anatomic changes may be presented in the retina of children with axial myopia.
