A 60-year-old man developed periodic alternating nystagmus in association with decreased vision due to cataracts. Prior to surgery, vision was limited to hand motion only in both eyes. An extracapsular cataract extraction with insertion of a posterior chamber intraocular lens was performed in the patient's left eye. On the first postoperative day, vision was 20/60 in the left eye and the nystagmus was absent with both eyes open. Periodic alternating nystagmus that occurs with poor vision is related to a loss of fixation. Surgery aimed at improving the visual status may be effective in extinguishing the nystagmus.
一名60岁男性因白内障导致视力下降，并出现了周期性交替性眼球震颤。手术前，双眼视力仅能达到手动。该患者左眼进行了白内障囊外摘除术并植入了后房型人工晶状体。术后第一天，左眼视力为20/60，双眼睁开时眼球震颤消失。视力不佳时出现的周期性交替性眼球震颤与注视丧失有关。旨在改善视力状况的手术可能对消除眼球震颤有效。
