What are the functions and efficacy of 0.01% atropine sulfate eye drops? How does it help treat myopia?

0.01% atropine sulfate eye drops (trade name: EIKANCE) is a drug used for ophthalmic treatment. It mainly helps control the progression of myopia by regulating eye muscle activity. Atropine sulfate is an anticholinergic drug that inhibits the effect of parasympathetic nerves on the eyes and reduces the contraction of the ciliary muscles, thereby affecting the adjustment function of the eyeballs. Especially in the treatment of myopia, the application of atropine has received widespread attention.

Myopia is a refractive error in which the axial length of the eyeball is too long or the refractive power of the cornea is too strong, resulting in the inability of light to accurately focus on the retina. Under normal circumstances, the eyes need to adjust the focus through the adjustment of the ciliary muscles, but for patients with myopia, the adjustment function of the eyes is overactive, causing the image of distant objects to always fall in front of the retina, forming a blurred image. 0.01% Atropine Sulfate Eye Drops helps slow down the excessive adjustment of the eyeball by reducing the adjustment function of the ciliary muscle, thereby effectively controlling the progression of myopia.

Studies have shown that low concentrations of atropine sulfate (such as 0.01% concentration) have shown significant effects in controlling myopia in children. Compared with high concentrations of atropine, low concentrations can reduce the growth rate of axial length without causing significant side effects, thereby effectively slowing down the increase in myopia. This is especially important for children and adolescents who are experiencing myopia progression, as this is the period when myopia develops most rapidly.
Specifically, 0.01% atropine sulfate eye drops can reduce the excessive force of the eyes by reducing the adjustment force of the ciliary muscle, thereby reducing the growth rate of the axial length of the eye, thereby slowing down the increase in myopia. The drug has a mild dilation effect on pupils and does not cause significant side effects such as light sensitivity, so it is relatively safe for long-term use.
In summary, 0.01% atropine sulfate eye drops have become an effective means of myopia control through its unique pharmacological effects, especially suitable for children and adolescents. It can significantly slow down the progression of myopia and provide a new option for ophthalmic treatment.
