Study Title:

Effect of bilberry extract on slowing high-myopia progression in children: 2-year follow-up study.

Study Abstract

Aim: To evaluate the effect of oral Difrarel on progression of high myopia in children and to study myopia course after its discontinuation.

Methods: A total of 64 highly myopic children were enrolled in this study. Patients were divided into two equal groups: group 1 was administered Difrarel for 1 year and stopped its intake for another year, and group 2 (control) did not take Difrarel. Refraction and axial length of the right eye of every subject were measured every 6 months in both groups.

Results: Each group had 32 eyes of 32 patients. The mean age was 9.34±2.27 years in group 1 and 9.33±2.2 years in group 2. Mean refraction and axial length at the start of the study were -10.78±2.6 D and 23.7±1.2 mm, respectively, in group 1, and -10.5±2.55 D and 23.9±1.4 mm in group 2. Refraction and axial length measurements every 6 months revealed statistically significant lower numbers in group 1 than group 2 after 1 year. After discontinuation of the drug, the difference between both groups remained significant.

Conclusion: Oral Difrarel slowed axial elongation and stopped myopia progression in children with high myopia. The drug effect was consistent after its discontinuation for 1 year.
