What is the Condition?
Also known as nearsightedness, myopia has become the most common eye problem amongst people, typically beginning in childhood. Myopia is characterized by a person being able to see near objects clearly, but have difficulty seeing distant objects.
A simple case of myopia could develop into high myopia, where the length of the eyeball becomes too long. This could lead to retinal detachment and retinal tears as well. At some point, abnormal blood vessels grow under this damaged retina, which will result in changed vision.
How does it Affect the Eye?
Myopia is characterized by blurry vision, because the affected eyes focus on images that are in front of the retina, rather than on the retina. Myopia could also take place due to an abnormal-sized lens or cornea, or even an elongated eyeball. The result of this condition is blurry or hazy vision that prevents the individual from seeing things clearly.
How Many Types of Myopia are there?
There are several types of myopia, namely:
This form of myopia occurs when your ciliary muscles spasm. The ciliary muscles are the muscles that are responsible for controlling how your eyes focus on things.
This is most common type of myopia that is a result of environmental conditions and genetics.
This form of myopia is most obvious during the nighttime, despite your vision functioning fine during the daytime.
This form of myopia takes place due to certain reasons, such as increase body glucose or nuclear sclerosis.
This form of myopia depends on the degree of refractive error in your eye(s), and gets worse as it progresses. As a matter of fact, it could lead to legal blindness. In degenerative myopia, your eye(s) keeps growing with time, which keeps worsening your blurry vision.
What are the Symptoms of this Condition?
The symptoms of this condition are as follows:
- It is difficult to see objects that are at a distance
- Vision can become blurry
- You will find yourself squinting
- Headaches and eye strain may occur as well
What are the Risk Factors for Developing this Condition?
A few risk factors for myopia include:
- Retinopathy of prematurity could lead to myopia, later in life
- If your family has a history of nearsightedness, you may acquire it as well
- Certain genetic disorders such as Marfan Syndrome are associated with the development of myopia
How is this Condition Treated?
There are a few ways to correct myopia:
Glasses or Contact Lenses:
Some common treatments for nearsightedness include wearing contact lenses or glasses. For mild cases of myopia, prescribed glasses or contact lenses do wonders. Contact lenses work as the first refractive surface for your eye(s), which allows better focus.
If you are considering refractive surgery, you must know that they are two types:
In this procedure, a thin flap is created on the cornea, some corneal tissue is removed and then the flap is put back to its old position. This is the most common form of refractive surgery.
In this procedure, the cornea is flatted by removing a layer of the corneal tissue. In this manner, light is then able to focus on the retina in an appropriate manner.
