ABSTRACT
AIM: To investigate curative effects of excimer laser corneal refractive surgery for adults or older adolescent with hyperopic anisometropic amblyopia.METHODS: From March 2014 to March 2016, we selected 26 cases 26 eyes of adults or older adolescent with hyperopic anisometropic amblyopia in our hospital.All eyes underwent laser in situ keratomileusis, observed for the uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), diopter and stereopsis.RESULTS: At the end of the follow-up, the patient`s spherical equivalent and anisometropia were 1.47±0.51D and 1.15±0.22D, were significantly lower than that before operation (P<0.05).At the end of the follow-up, the distance and near UCVA and BCVA were 0.26±0.13 and 0.23±0.09, 0.42±0.09 and 0.31±0.16, which were significantly higher than those before operation (P<0.05).At the end of follow-up, the visual function of the patients was significantly improved (P<0.05), the rate of postoperative visual function < 100 eyes was 23%.CONCLUSION: In adult or older adolescent with hyperopic anisometropic amblyopia, excimer laser corneal refractive surgery has a certain effect.
ABSTRACT
This prospective study was performed to measure the macular and the peripapillary retinal nerve fiber layer (RNFL) thicknesses using optical coherence tomography (OCT) in patients with anisometropic amblyopia. Thirty-one patients with hyperopic anisometropic amblyopia were included. The macular retinal thickness and the peripapillary RNFL thickness were measured using OCT. The mean refractive error was +3.71 diopters (D) and +1.00 D, the mean macular retinal thickness was 252.5 micrometer and 249.7 micrometer, and the mean RNFL thickness was 115.2 micrometer and 109.6 micrometer, in the amblyopic eye and the normal eye, respectively. OCT assessment of RNFL thickness revealed a significantly thicker RNFL in hyperopic anisometropic amblyopia (P=0.019), but no statistically significant difference was found in macular retinal thickness (P> 0.05). In conclusion, the amblyopic process may involve the peripapillary RNFL, but not the macula. However, further evaluation is needed.
