中文摘要 | 目的:Atropine可以控制近視進行,其一的機轉是阻斷調視力,本文主要探討 Atropine對調視力之影響。 方法:24位近視學童,等分成三組:0.1%、0.25%、0.5% Atropine組。這些均連續使用 Atropine六個月,調視力測量是以自覺式紅外線屈光儀(Nidek AA-2000)。數據的取得是用 藥前、及用藥一個月、兩個月、三個月、六個月後。 結果:調節張力和調節適應力在0.25%和0.5% Atropine均有意義的增加,而0.1%只有 些微增加。調節反應力三組均減少,0.25%比0.1%更低。調調節速度和回復時間均沒有什麼 影響。三組之瞳孔均有意義放大,且0.25%和0.5%比0.1%來得大。調節時之縮瞳調視作用 在0.25%和0.5%有意義減少,但0.1%只有輕微變化。 結論:0.25%對瞳孔調視力和0.5%相近,但0.1%之作用最少。 |
英文摘要 | Purpose. One of the mechanisms of atropine in controlling myopic progression was thought to block the accommodation. It is need to understand the changes of accommodation affected by the atropine. Methods. Twenty four myopic children were included. Three groups were equally divided: 0.1%, 0.25%, and 0.5% atropine. The subjects were using atropine for 6 months. The accommodative patterns were monitored with an objective infrared refractometer (Nidek AA-2000). Data were corrected before, then 1 month, 2 months, 3 months, and 6 months after using atropine. Results. The tonic accommodation and accommodative adaptation were significantly reduced in 0.25% and 0.5% atropine after 6 months, but only slightly in 0.1%. The accommodative response was also significantly reduced in all atropine groups after 6 months. The latency, speed and relaxation time of accommodation between groups were not significantly different. The pupil size was dilated in all atropine groups, and it was significantly larger in 0.25% and 0.5% than 0.1% atropine. The pupil miotic effect during and after stimulation were significantly reduced in both of 0.25% and 0.5%, but slightly in 0.1% atropine. Conclusions. The 0.25% atropine had similar effect on the pupil and accommodation as 0.5% atropine, however 0.1% atropine had least effect. |
