目的探讨先天性冲动型眼球震颤患者采用Parks法手术治疗前后的近立体视锐度变化。方法用颜少明等研著的《立体视觉检查图》(下文简称颜氏图)测定15例先天性冲动型眼球震颤患者术前第一眼位、静止眼位和术后第一眼位近立体视锐度。结果第一眼位双眼最佳矫正视力和近立体视锐度在术后较术前提高,差异有显著性。结论先天性冲动型眼球震颤患者经Parks修正法手术治疗后,症状改善,视力提高,近立体视觉也得以相应提高。
Objective To investigate the near stereoacuity changes of patients with congenital impulsive nystagmus treated with Parks method. Methods Yan Shaoming et al.’s “stereoscopic examination chart” (hereinafter referred to as Yan’s chart) measured 15 cases of congenital impulsive nystagmus in patients with preoperative first eye position, resting eye position and postoperative first eye near stereopsis Sharpness. Results The best corrected visual acuity and near stereoacuity in the first eye position were significantly improved after operation compared with that before operation. The difference was significant. Conclusion After congenital impulsive nystagmus patients underwent Parks correction surgery, their symptoms improved, visual acuity improved, and stereopsis improved accordingly.
