PURPOSE
To investigate the trend of refractive change in hyperopic patients according to increases in age. METHODS: Eighty-eight children who had hyperopia of more than +1.50 diopters (D) and could be followed up for at least 5 years were included in this study. We divided the patients into two groups according to the level of initial hyperopia and retrospectively analyzed hyperopic refractive changes over a 5-year period according to age at initial diagnosis, presence of esotropia, amblyopia, astigmatism and anisometropia. RESULTS: We gained the following formula about the aspect of hyperopic reduction in 88 patients over a period of 5 years: Diopter (D)=7.99-2.14 Ln (age). The presence of anisometropia and amblyopia did not affect hyperopic reduction. Hyperopic reduction amounts in the group with a hyperopic eye of more than +5D at initial diagnosis were greater than in the group with a hyperopic eye less than +5D, and greater in the group with an astigmatic eye of more than 1D. The presence of esotropia and the age at initial diagnosis did not affect hyperopic reduction. CONCLUSIONS: We show that emmetropization in hyperopic children occurs according to the following formula: Diopter (D)=7.99-2.14 Ln (age). Both the initial level of hyperopia and the concurrent presence of astigmatism affected hyperopic reduction. However, the presence of anisometropia, amblyopia, esotropia and the age at initial diagnosis did not significantly affect hyperopic reduction. |
