| Abstract |
|
We reviewed records of 50 bilateral hyperopic amblyoic patients who visited ophthalmologic clinic at Yeungnam University Hospital between December 1984 and October 1993, and investigated the effect of age at initial correction, magnitude of hyperopia and duration of correction on corrected visual acuity with the lapse of time. Criteria for selection included the followings; hyperopia of 3.50 diopters or more, astigmatism of 2.50 diopters or less, and anisoametropia of 1.25 diopters or less. Full cycloplegic corrections were prescribed at the initial visit to all subjects. The distribution of initial corrected visual acuity was 0.1 to 0.5. Age at initial correction varied from 2 years to 8 years(mean 3.98 years). The magnitude of hyperopia appeared to have the greatest influence on the visual outcome at initial correction. Duration of correction also influenced on the visual outcome, showing continuous visual improvement during 4 years after initial correction. The age at initial correction did not appear to influence on the initial and final corrected visual acuity. A comparision between initial and final corrected visual acuity showed a sigificant difference, irrespective of age at the intial correction or magnitude of hyperopia. |
