Effect of Serum Vitamin D on MARPE Treatment Response

A total of 30 patients are planned to be included in the study during the first half of 2025, who will apply to the clinic. In our clinical routine, approximately 30% of RME patients are treated using the MARPE method. The patients will be randomly assigned to two different groups. The first group will be referred to the Pediatric Endocrinology outpatient clinic at NEU Faculty of Medicine for vitamin D level measurements at the beginning of the treatment. The second group will proceed with treatment as usual, without vitamin D measurement. At the end of the treatment, vitamin D levels of all patients in both groups will be measured.
