摘要

到底看電視會不會誘發近視的產生呢？我們利用兩隻三個月大的台灣彌猴，從小給予看電視；我們是利用20吋電視，觀看時间每天12小時，觀看距離1公尺。另外四隻同年齡彌猴未看電視作為對照組。三個月大彌猴之眼球平約屈光度為+1.38±0.72D，觀看一年後平均屈光度為-0.25±2.34D，然後停止觀看一年後平均屈光度為-4.19±2.39D，再追踪一年後屈光度為-8.69±1.48D。所以，在視力發育時間長時間及短距離地觀看電視可以誘發近視的產生，而且此種近視甚至在停看電視後，仍持續進行；因而，此種早發性近視和遲發性近視（即所謂學校性近視）其產生的基本機轉可能不同。

Purpose. TV program is very attractive to all of the children and they spend a lot of time in watching TV. Does watch TV during the age of visual development can be a factor to the production of myopia? We used animal model to approach this study.
Methods. Two 3 months old monkeys were studied. Twenty inches TV was putting around 1 meter before the cages and switch was set on 12 hrs on/off cycle. We tried to enforce the monkeys to watch TV from noon to midnight for the first year and then stop watching for the following years. Another 4 monkeys without TV watching leave for controls. We followed up for three years.
Results. The initial mean refractive status of 3 months old monkeys was +1.38±0.72 D for four eyes. After one year, the mean refractive status became -0.25±2.34 D. Then the monkeys stopped TV watching. The mean refractive status of the second year became -4.19±2.39 D, but the control group without watching TV was +0.95±0.37 D. After another one year, the mean refractive error of TV monkeys became -8.69±1.48 D. Thus, TV watching during the age of visual development could induce myopic production, and the myopia progress continuously even stop the TV watching.
Conclusions. These results suggested that watching TV under long watching time and short watching distance may trigger the development of myopia. This early onset myopia can progress continuously even without any environmental factors. However, the mechanisms of early onset myopia may be different to the school myopia which is late onset myopia.
