摘要:
目的　探讨角膜塑形术对中低度近视眼的对比敏感度、调节近点、调节灵敏度、正负相对调节的影响及其动态变化过程。方法　连续收集２００９年８月至２０１３年８月就诊的青少年中、低度近视患者８３例１６６眼。按戴镜时间分为４组：１组（戴镜前５０例９９眼），２组（戴镜后１～３个月３６例７２眼），３组（戴镜后时间＞３～１２个月３８例７６眼），４组（戴镜后时间＞１２～４０个月４２例８４眼）。检查对比敏感度，采用移近法测定调节近点，测定正、负相对调节，±２．００Ｄ翻转拍测定调节灵敏度。结果　（１）对比敏感度：与１组（３ｃ·ｄ－１：１．８０±０．１６；６ｃ·ｄ－１：２．０６±０．１５；１２ｃ·ｄ－１：１．８４±０．１５；１８ｃ·ｄ－１：１．４２±０．１５）比较，２、３、４组各空间频率均下降，差异均有统计学意义（均为Ｐ＝０．０００）。（２）调节近点变化：与１组（９．１０±１．８８）ｃｍ比较，２、３、４组调节近点分别为（７．７４±１．９０）ｃｍ、（７．４３±１．３５）ｃｍ、（７．０３±１．２６）ｃｍ，差异均有统计学意义（均为Ｐ＝０．０００）。（３）单眼调节灵敏度变化：与１组（８．７０±２．４６）周·ｍｉｎ－１比较，２组差异无统计学意义（Ｐ＝０．９０）；３组、４组调节灵敏度均增加，差异均有统计学意义（Ｐ＝０．０２、Ｐ＝０．００６）。（４）相对调节：正相对调节，与１组（－２．０７±０．８８）Ｄ比较，２组差异无统计学意义（Ｐ＝０．１１０）；３组、４组正相对调节均增加，差异均有统计学意义（Ｐ＝０．００１、０．００６）。负相对调节：与１组（＋２．５７±０．５８）Ｄ比较，２组、３组差异均无统计学意义（Ｐ＝０．２３、０．９８），４组负相对调节减少（Ｐ＝０．００２）。结论　角膜塑形术引起各空间频率对比敏感度阈值均下降，调节能力增加。调节灵敏度、正相对调节能力保持稳定后呈增加趋势，负相对调节能力保持稳定后呈下降趋势。
Abstract:
Objective To evaluate the dynamic changes of contrast sensitivity ( CS) .accommodation nearpoint ( NP) . accommodative facility ( AF) , positive relative accommodation ( PRA) ,negative relative accommodation ( NRA) after orthokeratology (OK). Methods Retrospective clinical study. Eighty-three myopia subjects ( 166 eyes) from August 2009 to August 2013 in our hospital were enrolled. Four groups were divided based on wearing OK lens time : Group I ( before wearing , 50 cases , 99 eyes) , group 2 (1 -3 months after wearing ,36 cases,72 eyes) , group 3 ( >3 - 12 months after wearing,38 cases, 76 eyes) , group 4 ( > 12 - 40 months after wearing, 42 cases, 84 eyes) . CSV-IOOOE was used to measure CS,the subjective push-up method was used to test NP, Phoropter( Nidek RT-600 ) was used to measure PRA/NRA, + 2. 00 D flippers was used to measure AF. Results Compared with group I (1. 80 +0. 16 .2. 06 +0. 15 . 1. 84 +0. 15 ,1. 42 + 0. 15) , CS at different spatial frequencies (3 c . d ’1 .6 c . d ’I , 12 c . d ’l . 18 c . d-l ) in group 2 ,3 ,4 all decreased ( all P = 0. 000) . NP in group I ,2 ,3 ,4 were ( 9. 10 + 1. 88) cm. (7. 74 + 1. 90) cm , (7. 43 + 1. 35) cm and ( 7. 03 + 1. 26 ) cm , respectively ,there were sigruficant differences of group 2 ,3 and 4 compared with group I ( all P = 0. 000 ) . Compared with group I ( 8. 70 + 2. 46 ) circles per minute . there was no change in AF of group 2 (P = 0. 90 ) . and increased in group 3 and 4 (P = 0. 02 .P = 0. 006 ) . Compared with group I ( - 2. 07 +0. 88) D. there was no change in PRA of group 2 (P = 0. 110) , and increased in group 3 and 4 (P = 0. 001 ,P = 0. 006 ) . Compared with group l , there was no change in NRA of group 2 and 3 (P = 0. 23.P = 0. 98 ) . and decreased in group 4(P = 0. 002 ) . Conclusion All CS will be increased, and accommodation will be increased after wearing OK lens. AF and PRA present the increased tendency , and NRA present the decreased tendency.
