摘要
目的 分析目前市场上流行的中药眼贴对于长时间接触视频终端的视疲劳患者的治疗效果.方法 随机对照双盲试验.把100例18～40岁、长时间接触视频终端(≥8 h/d)并具有视疲劳症状的受试者随机分为两组,一组为中药眼贴(含有野菊花、丹参、珍珠粉和薄荷脑等成分),一组为对照眼贴(不含任何中药成分).在贴敷眼贴之前和贴敷眼贴后,采用Log MAR视力表检查远视力,采用双眼开放式调节力测量仪检查视远(5 m外)和视近(33 cm)时的调节反应.结果 实际纳入94例受试者,眼贴组和对照组各47例,两组受试者的平均年龄为(26.1±3.9)岁和(25.9±4.4)岁(t=0.27,P=0.55),屈光度为(-2.41±3.32)D和(-3.03±3.53)D(t=0.88,P=0.58),基线资料无差异.贴敷眼贴后,两组受试者右眼的远视力变化值分别为-0.00±0.07和-0.01±0.05(t=0.71,P=0.40),视远调节反应变化值为0.06±0.42和-0.01±0.42(t=0.84,P=0.88),视近调节反应变化值为-0.23±0.55和0.02±0.33(t=-2.65,P=0.003).结论 中药眼贴贴敷后视疲劳受试者在近距离(33 cm)时的调节反应显著增大,有助于减轻视频终端视疲劳.
Objective To analysis the therapeutic effect of the traditional Chinese medicine paster on asthenopia in patients who work at video display terminals for a long time. Methods Randomized, controlled, double-blind trail. 100 asthenopic patients( aged 18-40 years) with a history of long-term working at video display terminals( ≥8 hours / day) were randomly divided into two groups. One group was administrated by traditional Chinese medicine pasters containing wild chrysanthemum,dan-shen,pearl powder,mentha-camphor and so on. The other group was controls given the pasters without any traditional Chinese drugs. The distance vision was tested with Log MAR visual chart before and after using the pasters. Accommodative responses at distant( 5 m) and near target( 33 cm) were examined by binocular open field accommodation measurement instrument. Results Ninety-four patients were finally included and 47 patients in each group. There were no statistical differences between the two groups in baseline data,with mean age of 26. 1 ± 3. 9 years and 25. 9 ± 4. 4 years( t = 0. 27,P = 0. 55),and refraction error of- 2. 41 ± 3. 32 D and- 3. 03 ± 3. 53 D( t = 0. 88,P = 0. 58),respectively. After using the pasters,the changes in distant visual acuity of right eye in each group were- 0. 00 ± 0. 07 and- 0. 01 ± 0. 05( t = 0. 71,P = 0. 40). The changes in accommodative responses at distant were 0. 06 ± 0. 42 D and- 0. 01 ± 0. 42 D( t = 0. 84,P = 0. 88),respectively. The accommodative changes at near were- 0. 23 ± 0. 55 D and 0. 02 ± 0. 33 D( t =- 2. 65,P = 0. 003) in the paster group and the control group,respectively. Conclusion The accommodative responses at near( 33 cm) of asthenopic patients were significantly increased after using the traditional Chinese medicine pasters,which is beneficial to release asthenopia in patients working at video display terminals.
