Iris tissue after medical abortion

The human body structure is very complex. The human eyes alone have a very complex organizational structure. Anyone who has some understanding of the structure of the human eye should know that the iris tissue plays a very important role in the eye. It is mainly used to adjust the size of the pupil. However, some women find that the iris tissue in their eyes changes after undergoing medical abortion. So is there any relationship between medical abortion and iris tissue?

1. The iris belongs to the middle layer of the eyeball, located at the front of the vascular membrane, in front of the ciliary body. It can adjust the size of the pupil and the amount of light entering the eye. There is a pupil in the center of the iris. There are iris granules on the edges of the pupils of horses and cows.

2. The pigmented annular membrane in the front of the eyeball is composed of connective tissue cells, muscle fibers, etc., with the pupil in the middle. The color of the eye is determined by the amount of pigment contained in the iris. [1] It contains two layers of smooth muscle with opposing effects, which cause it to contract in low light (dilate the pupil and increase the amount of light reaching the retina) and to relax in high light (contract the pupil).

3. Colors: Mainly blue and brown, other colors are mixed. Physical constitution can be roughly differentiated based on color: blue indicates an acidic constitution and brown indicates a choleric constitution. Other possible pigmentation issues include the appearance of brown or abnormal pigmentation on the iris, which have different meanings depending on where they appear. The structure can basically be divided into silk, linen, mesh, etc., mainly based on the density of the fibers. The denser the fiber, the stronger the fiber. In addition, holes or abnormal arrangement of fibers are signs of disease.

The iris is mainly composed of connective tissue, which contains pigments, blood vessels, and smooth muscles. The color of the iris varies depending on the amount and distribution of pigment, and generally comes in black, blue, gray, and brown. There are smooth muscles in the iris that are arranged around the pupil, called the mydriasis muscle (pupillary sphincter), and smooth muscles that are arranged radially around the pupil, called the mydriasis muscle (pupillary dilation muscle). The former is innervated by the parasympathetic nervous system, and the latter by the sympathetic nervous system. When strong light shines into the eyes, the pupillary sphincter contracts to limit the light entering; when the light is weak, the pupil dilator muscle dilates the pupil to increase the light entering. The normal pupil size is also related to many factors such as age and refractive status. The pupils of infants under one year old are the smallest, then gradually increase in size, and then gradually become smaller after puberty. The pupil of a myopic eye is larger than that of a hyperopic eye. When a person is in pain or frightened, their pupils dilate, while when they are asleep, their pupils shrink.
