眼球震颤患者配戴RGP临床观察

Clinical observation of nystagmus patients taking with RGP

目的探讨眼球震颤患者配戴RGP的临床效果。方法随机选择14例眼球震颤患者，为其进行眼前节、眼底、屈光、角膜曲率、角膜地形图、眼球震颤幅度，震颤频率检查，然后选择合适基弧的RGP镜片，并追加度数，随访观察1．5年。结果配戴RGP前矫正视力0．32±0．22，戴后0．55±0．29，差异显著有统计学意义（t=-8．33，P〈0．05）。戴RGP前振幅（15±5）mm，戴后（10±5）mm，差异显著有统计学意义（t=12．96，P〈0．05）。戴RGP前震频（35±10）次／min，戴后（25±10）次／min，差异显著有统计学意义（t=14．23，P〈0．05）。期间丢片有2例，其余患者均能较好护理镜片。结论眼球震颤患者在配戴RGP后视觉质量提高，矫正视力提高，振幅、震频降低。

Objective To investigate the clinical effect of the nystagmus patients taking with RGP. Methods Fourteen nystagmus patients were fitted with RGP contact lens. Evaluation of it was done. The period of follow-up ranged 18 months to observe the changing of vision, vibration, and frequency. Results The results showed that the beginning corrected vision was 0.32±0.22, after 18 months was 0.55±0.29, the difference was significant （P 〈0.05）, the beginning vibration was 15± 5, after 18 months was 10±5, the difference was significant （P 〈0.05）, the beginning frequency was 35±10, after 18 months was 25±10, the difference was significant （P 〈0.05）. Conclusions Wearing RGP can make the nystagmus patients＇ corrected vision improved ,vibration and frequency decreased.
