目的:调查不同年龄段民航飞行员对比敏感度( contrast sensitivity,CS),分析其特征,以期获得正常参考值。<br> 方法:随机选取2013-09/2014-07在民航总医院进行年度体检的现役民航飞行员,要求任何一眼裸眼视力≥1.0,无眼部疾病及相关全身疾病,按不同年龄将其分为4组,A组(20~29岁)、B 组(30~39岁)、C 组(40~49岁)、D组(50~59岁),每组50名100眼,应用 OPTEC 6500视功能检测仪检测每眼在明视和暗视状态下不同空间频率的CS。<br> 结果:各年龄段民航飞行员CS曲线均呈“倒U形冶改变,在中频区(3.0c/d和6.0c/d)最高。明视状态下,空间频率6、12和18c/d,D组与其他三组比较,CS值降低,差异具有统计学意义(P<0.01);暗视状态下,空间频率1.5、3和6c/d,D组与其他三组比较,CS值降低,差异具有统计学意义(P<0.01)。<br> 结论:该调查较为客观地反映了不同年龄段民航飞行员的CS特征,为深入研究民航飞行员的视功能特点以及获得民航飞行员CS正常值提供了参考依据。
目的:調查不同年齡段民航飛行員對比敏感度( contrast sensitivity,CS),分析其特徵,以期穫得正常參攷值。<br> 方法:隨機選取2013-09/2014-07在民航總醫院進行年度體檢的現役民航飛行員,要求任何一眼裸眼視力≥1.0,無眼部疾病及相關全身疾病,按不同年齡將其分為4組,A組(20~29歲)、B 組(30~39歲)、C 組(40~49歲)、D組(50~59歲),每組50名100眼,應用 OPTEC 6500視功能檢測儀檢測每眼在明視和暗視狀態下不同空間頻率的CS。<br> 結果:各年齡段民航飛行員CS麯線均呈“倒U形冶改變,在中頻區(3.0c/d和6.0c/d)最高。明視狀態下,空間頻率6、12和18c/d,D組與其他三組比較,CS值降低,差異具有統計學意義(P<0.01);暗視狀態下,空間頻率1.5、3和6c/d,D組與其他三組比較,CS值降低,差異具有統計學意義(P<0.01)。<br> 結論:該調查較為客觀地反映瞭不同年齡段民航飛行員的CS特徵,為深入研究民航飛行員的視功能特點以及穫得民航飛行員CS正常值提供瞭參攷依據。

AIM:To survey civil aviator contrast sensitivity ( CS) of different ages and analyze the characteristic of it in order to obtain the normal reference value. <br> METHODS: Four hundred eyes of 200 commissioned civil aviators from Civil Aviation General Hospital from September, 2013 to July, 2014 were randomly divided into four groups:group A (age 20~29), group B (age 30~39), group C (age 40~49), group D (age 50~59), and 50 people in each group ( 100 eyes ) . All of the eyes naked vision had to be ≥1. 0, with no eye disease and associated systemic diseases. The CS of different spatial frequencies was measured with OPTEC 6500 under light and dark room. <br> RESULTS:The CS curves of groups were all presented with inverted U shape, and the CS was highest in intermediate frequency area ( 3. 0c/d and 6. 0c/d ). Compared with that in the rest three groups, the values of CS at spatial frequency (6, 12 and 18c/d) under light room were decreased in group D, with statistical significance ( P<0.01 ) . Compared with that in the rest three groups, the values of CS at spatial frequency (1. 5, 3 and 6c/d) under dark room were decreased in group D, with statistical significance (P<0. 01). <br> CONCLUSION: This survey objectively reflects the characteristics of civil aviator CS of different ages, and provides reference date for further study on civil aviator visual function characteristics and obtaining the normal reference value of civil aviator CS.
