目的利用眼间噪音掩盖技术结合快速对比敏感度测试技术（qCSF）测量弱视患者眼优势度，分析其可行性。方法实验研究。共10例成人弱视患者（弱视组）和17例正常成人对照者（正常组）参与了本研究。双眼先后作为测试眼和非测试眼，给非测试眼分别呈现空间滤波后的噪音和空白背景，测量测试眼的对比敏感度曲线，两者的差值即为非测试眼对测试眼的抑制度。测试时为有效地排除弱视眼对比敏感度损伤对测量结果造成的干扰，设定噪音图案的对比度值为噪音对比度阈值的5倍。数据采用重复测量的方差分析进行比较。结果弱视组不同空间频率抑制度大小眼间差异存在统计学意义（F=24．25，P〈0．01）；而正常组不同空间频率抑制度大小眼间差异无统计学意义（F=0.32．P〉0．05）。此外，弱视组的弱视眼对其对侧眼的抑制度显著低于正常组的非优势眼对其优势眼的抑制度（b24．29，P〈0．01）；弱视组对侧眼对弱视眼的抑制度略微高于正常组优势眼对其非优势眼的抑制度。但差异无统计学意义（F=3．81，P〉0．05）。结论弱视患者存在显著的眼间相互抑制不平衡，表现为弱视眼不能有效抑制对侧眼，而弱视对侧眼对弱视眼的抑制水平与正常人相当。我们认为这一现象可能是导致弱视患者双眼空间视觉损伤的基础。
