英文摘要 | Background: Dynamic retinoscopy is a well-described but often overlooked technique that allows rapid assessment of accommodative ability. We want to evaluate the application of dynamic retinoscopy in hypermetropic children with or without amblyopia. Methods: From Jan. 1999 to Jan. 2001, 60 eyes of 40 patients were enrolled in this study. Patients were selected based on the hyperopic refractive error (ranged from +0.25D to +5.00D, mean+2.73D) according to their medical records. The average age was 6.7 years, ranged from 4 to 11 years. Dynamic retinoscopy was performed on 28 eyes with amblyopia and 32 eyes without amblyopia then the results of dynamic retinoscopy were recorded. Results: All non-amblyopic eyes (53.3%) showed the “rapid, complete, steady” normal response. On the other hand, all the blyopic eyes (46.7%) revealed abnormal responses, “incomplete” (35.7%), “asymmetric” (35.7%) and “unsteady” (14.4%) were the most of all. Conclusions: In our study, all subjects with good accommodative ability will not develop amblyopia even with moderate-to-high degree of hyperopia. On the other hand, subjects with poor accommodative response will have high risk of developing amblyopia even with mild degree of hyperopia. Therefore this clinical tool can be used as a convenient and rapid guide providing critical data about accommodative ability that can help us solve diagnostic or therapeutic dilemmas involving hyperopic amblyopia, especially in preverbal children. |
