Myopic Progression in Girls with Gonadotrophin-Releasing Hormone Agonist Treatment for Central Precocious Puberty.

Abstract
We sought to determine whether the myopic progression of patients with central precocious puberty (CPP) who were undergoing treatment differed from that of their healthy peers with normal pubertal onset and progression. Eighteen girls with CPP and 14 age-matched controls who underwent regular ophthalmic examinations for at least 1 year were included. All the CPP patients received a 3.75 mg leuprolide acetate depot subcutaneously every 28 days. The spherical equivalent (SE) and axial length (AL) for myopia progression and the pubertal parameters (height, body weight, body mass index, Tanner stage, and bone age) were compared between the two groups. Of 32 subjects with a mean age of 8.6 ± 0.7 years, the SEs and ALs did not differ at baseline between the two groups, which had similar weight and similar body mass index. After 1 year, both the CPP patients and controls showed myopic progression, with an average myopic shift of -0.73 ± 0.48 diopters (D) and AL elongation with a mean change of 0.44 ± 0.61 mm. The SE and AL changes over 1 year were greater in the controls than those in the CPP patients, which was not statistically significant (-0.85 ± 0.55 D vs. -0.64 ± 0.41 D and 0.55 ± 0.89 mm vs. 0.35 ± 0.22 mm, respectively). The change in AL correlated significantly with the change in the height (β = 0.691, p = 0.039). In this 1-year study, the CPP patients with treatments trended to show less myopic progression than the controls.
