目的 调查浙江省盲校学生视力状况,评价屈光矫正和低视力康复效果.方法 横断面调查研究.对219例来自浙江省3所盲校的学生采用裂隙灯检查眼前节、用眼底镜检查眼底,并进行UCVA、屈光度和BCVA检查,采用4×、6×或8×的单筒望远镜进行低视力康复.采用配对t检验对康复检查结果进行分析.结果 屈光矫正前后患者视力比较差异有显著的统计学意义(3.53±0.34 vs.3.85±0.27,t=-14.997,P＜0.01),153例BCVA＜3.7,66例BCVA≥3.7.盲患者配戴远用助视器前后视力比较差异有统计学意义(2.03±0.94 vs.2.12±1.06,t=-5.537,P＜0.01),低视力患者比较差异也有统计学意义(3.90±0.23vs.4.55±0.24,t=-28.537,P＜O.01).配戴远用助视器后脱盲率为24％,低视力患者的脱残率为80％.结论 屈光矫正和助视器验配可以有效地改善盲和低视力患者远视力,对患者进一步接受教育极其重要.

Objective To evaluate the effect of refraction and visual rehabilitation on students in schools for the blind in Zhejiang province.Methods In this cross-sectional investigation,219 students in 3 schools for the blind in Zhejiang province were included.The students underwent eye examinations,visual acuity tests,refractive correction and low vision rehabilitation.Results were analyzed with a paired t test.Results The differences in visual acuity were significant after refraction (3.53±0.34 vs.3.85±0.27,t=-14.997,P＜0.01).The BCVA of 153 patients ＜3.7,and 66 patients ≥3.7.The differences in visual acuity were also significant after using a telescopic device (2.03±0.94 vs.2.12± 1.06,t=-5.537,P＜0.01) for blind patients and for low vision patients (3.90±0.23 vs.4.55±0.24,t=-28.537,P＜0.01).After using a telescope,distance visual acuity was ≥3.7 in 24％ of blind children and was ≥4.5 for 80％ of low vision children.Conclusion Refraction and low vision aids can improve students' visual acuity which is important to further their education.
