为探讨微小斜视和小角会聚性斜视抑制暗点的类型、大小和深度，对14例斜视患者和4例正常人进行了双眼静态视野检查。斜视患者客观斜视角1 ~ 8 °，视力0.1 ~ 1.25，立体视功能受限。在测试过程中，受试者在两台Friedmann视野分析仪上融合图片，在单眼和双眼观看条件下分别研究右眼和左眼。5例斜视患者斜视眼出现抑制暗点，直径5-30 °，深度4 ~ 14 dB。在其他9名受试者和4名正常人中均未检测到抑制暗点。总之，只有36%的斜视受试者存在抑制暗点，这些暗点集中在斜视眼的注视点周围，在某些情况下还包括中心凹区域，并且深度和大小不同。(C)1997 Elsevier Science Ltd.
In order to elucidate the type, size and depth of suppression scotomata in microstrabismus and small angle convergent strabismus, we performed binocular static perimetry in 14 subjects with strabismus and four normal observers. The strabismic cases had an objective angle of convergent squint between 1 and 8 deg, visual acuity between 0.1 and 1.25, and limited stereopsis. During testing the subjects fused pictures on two Friedmann visual field analyzers, Right and left eyes were studied separately under both monocular and binocular viewing conditions. In five strabismics a suppression scotoma was found in the squinting eye, with a diameter of 5-30 deg and a depth ranging from 4 to 14 dB. No suppression scotomata could be detected in the nine other subjects nor in the four normal observers, In conclusion, only 36% of subjects,vith strabismus were found to have a suppression scotoma, These scotomata were centered around the fixation point of the squinting eye, in some cases also encompassing the foveal area, and varying in depth and size.
