Retinal Changes in Vitamin D Deficiency

Retinal tissue parameters of pediatric patients with vitamin D deficiency will be evaluated in this prospective case-control study. The patients will be divided into 2 groups according to the vitamin D level. Retinal vessel diameters, retinal nerve fiber evaluation, choroidal thickness will be evaluated. Choroidal thinning decrease in retinal artery diameter and increase in retinal vein diameter will be detected in the vitamin D deficiency group.

The study of the relationship between vitamin D status and retinal diseases is a new concept, and there is a large gap in research focusing on the pediatric population in the literature. The importance of vitamin D in retinal maturation and its role in the development of retinal diseases at a young age is being investigated. In this sense, as far as known, it is the first study investigating retinal structure parameters in pediatric patients with vitamin D deficiency.
