| 목적 : We investigated the prognosis and risk factors for amblyopia in myopic children under four years of age.방법 : Twenty-four children with cycloplegic refractive error of ≥5.00 diopters (D) (spherical equivalent) in each eye, age < 4 years old at the time of the first visit, and follow-up until the patient was >8 years old were enrolled. Best-corrected visual acuity (BCVA), refractive errors and the presence of strabismus were evaluated serially from at least 4 years to over than 8 years. The children were divided into 2 groups according to BCVA at 8 years. A BCVA worse than 20/40 in either eye was considered as the presence of amblyopia.결과 : Amblyopia was detected in 7 out of 24 (29.2%) patients who were 8 years old. The refractive error was similar in amblyopic and non-amblyopic children at both 4 and 8 years of age. Strabismus (exotropia and esotropia) was more common in the amblyopia group; 3 patients were found to have constant esotropia, and 2 had intermittent exotropia. A significant correlation was found between refractive errors at 4 years of age and BCVA at 8 years of age (Spearman rho = 0.417, P = 0.009). BCVA at 4 years of age was also strongly correlated with BCVA at 8 years of age (Spearman rho = 0.517, P = 0.001).결론 : Early onset myopic children who have strabismus or severe astigmatism may develop amblyopia. |
