近视眼隐性内斜视患者50例戴镜4mo～5a随访

A follow-up of esophoria in 50 myopes wearing spectacles for 4 months to 5 years

目的:近视眼隐性内斜视(隐内斜)患者,在戴镜后仍会加速进展。通过随访各种不同方法配镜后近视度的变化,指导配镜选择。方法:对2004/2009年视光门诊收集完整的50例近视眼隐内斜患者的配镜资料及门诊病历,逐年统计。对不同时期、戴不同种类的眼镜后,近视度变化的值,按球镜、柱镜换算成每年屈光度变化的均值,再作均值之间的配对t检验。戴镜分普通眼镜、降-1.50DS近用镜、学生渐变多焦镜(MC镜)和阅读附加镜。结果:MC镜较普通镜在控制球镜度的进展方面,已有非常显著的统计学意义(P<0.01);阅读附加镜较MC镜在控制球镜、柱镜的屈光度变化方面均有非常显著的统计学差异(P<0.01);MC镜长期戴镜后有柱镜度增加、最佳矫正视力下降的现象;改用阅读附加镜后,最佳矫正视力提高。结论:近视眼隐内斜患者带普通眼镜后近视度增加较快,戴近用镜(降-1.50DS)和MC镜后次之,戴阅读附加镜效果理想。

AIM： To determine the impact of wearing several kinds of spectacles on progression of 50 myopia cases with esophoria. METHODS： Fifty myopia with esophoria were collected from 2004-2009, and whose refraction data and medical records were analyzed yearly. Wearing spectacles were ordinary glasses, reading glasses （reducing -1.50D）, multifocal lens （MC）, and reading additional lens, respectively. The refraction change of the four groups were analyzed by paired sample t- test. RESULTS： There were 50 patients ,aged 9 to 17 years （12.04±2.53）, 26 males and 24 females. MC was better than ordinary glasses in controlling the increase of degree of sphere in myopia （P〈0.01）. Reading additional lens were more effective in controlling the increase of degree of sphere and cylinder than MC（P〈0.01）.The degree of cylinder could increase and the best-corrected visual acuity could decrease because of long-time wearing of MC, while wearing reading additional lens could improve the best-corrected visual acuity. CONCLUSION： Myopia progression is faster in patients wearing ordinary glasses than reading glasses （reducing -1.50D） and MC. Myopia progression will slow down wearing reading additional lens.
