        • Study on the Contrast Sensitivity on the Astigmatism Eyes in Patients with Monocular Amblyopia Patients

          目的:分析探討單眼散光弱視患兒對比敏感度(CS)視功能的受損特點。方法:對正常兒童組36例、單眼散光弱視組34例、單眼非散光弱視組33例,共103例,用靜態F.A.C.T圖表和計算機Gabor斑CS檢查程序分別檢查患兒對側眼、弱視眼及90°和180°兩主子午線方向上的對比敏感度。結果:①單眼散光弱視組和單眼非散光弱視組的對側眼、弱視眼的CS值在所有空間頻率均較正常組的CS降低(Plt;0.05),表現為中、高空間頻率區CS的明顯受損(Plt;0.01)。②單眼散光弱視組的弱視眼在90°和180°兩主子午線方向上的對比敏感度有顯著差異(Plt;0.01)。結論:弱視兒童的對側眼不正常。用計算機Gabor斑檢查可以了解弱視散光兒童不同子午線上的CS存在的差異,明確定位弱子午線,并可以針對子午線性弱視,進一步開展知覺學習的治療。
