近年来,笔者诊治2例眼球震颤阻滞综合征(NBS)。报告如下。 例1:男,25岁。自幼双眼水平摆动不能固定,6月左右发现内斜视,1～2岁发现歪头视物,4岁时看细致物体时内斜视加重,看远物体时减轻,现在内斜视固定。查体:视力右0.7,左0,3,双眼视力0.8(均在代偿头位状况下检查),右眼内斜+35°,为注视眼。第一眼位无眼球震颤,外转时眼震明显加重,内转时减轻。左眼不能注视。双眼水平运动时若使用外转眼注视则双眼运动正常,若使用内转眼注视则外转眼不到位,表现假性外直肌不全麻痹。代偿头位为面向右侧转,即使遮盖左眼或在左眼前加与斜视角等量的三棱镜后内斜视及头位不
In recent years, I diagnosed two cases of nystagmus syndrome (NBS). The report is as follows. Example 1: Male, 25 years old. Since childhood, the level of his eyes can not be fixed swing around estrus found in June, 1 to 2 years old found tilted head visual objects, 4 years old to see the detailed objects within the strabismus to increase, looking away from the object to reduce, now esotropia fixed. Physical examination: visual acuity 0.7, left 0,3, binocular visual acuity 0.8 (check in the compensatory head position conditions), right eye oblique + 35 °, for the fixation of the eye. The first eye without nystagmus, nystagmus significantly increased when the external rotation, reduced within the turn. Left eye can not watch. If the use of horizontal eye movement outside the eyes to look at the normal eye movement, if the use of the inner orbital eye watching is outside the eye is not in place, the performance of pseudo external rectus abscess paralysis. Compensation head for the right turn, even cover the left eye or in front of the left eye and squint angle plus the same amount of prism after esotropia and head position
