Hello, I'm new here. I am in my first year of pharmacy college and I have learned a few drugs that act on the eyes and I have been studying the eyes and myopia. I am here to start a topic to see if drugs can be used to treat it. I am just going to talk about what I learned from my research so far, I am still a student and I would be happy if someone corrected me.
I think I have acquired myopia or self induced myopia from being too close to a computer screen and bad eye habits for so many years. I think what happens is the ciliary muscle in the eye that controls focusing becomes over works and spasms. Just like any other muscle would from over use, the ciliary muscle contracts for near vision and prolong contraction causes this spasm. The muscle then does not want to relax for far vision, I believe because trigger points form in it. Trigger points are sore spots you can feel in your skeletal muscles like on your back, a spot that feels really tender and releases when massaged. Trigger points in the cililary muscle are not as easly treated though because they are inside your eye.
I think this type of self induced myopia can be cured by drugs such as tropicamide and atropine. Tropicamide paralysis the ciliary muscle, its the eye drops that optometrists use to dilate the pupil for eye exams so I heard. I never actually had an eye exam where it was used though.
So I think with the cililary muscle paralyzed it will be completely relaxed for far vision I should be able to see perfectly at far vision. I think the use of such eye drops would loosen up the eye muscles which are tight and cant relax for far vision.
I think the palming method works on the same principles, when you cup your eyes your puplis dialate which also causes your cililary muscle to dialate and relax.
I also think this is how the Bates method works. The exercises help you to slowly relax your cililary muscle making it more flexable. I have not read bates book, but I believe that the use of tropicamide could be an easier and much faster way to cure myopia or could suppliment the exercises.
