Yes, this is one of your most valuable assets. Because it is so important to keep your eyes healthy, these are the ten most common problems that people face with their own eyes. If any of these actions apply to you, contact your eye doctor as soon as possible before your condition threatens your vision.
It is characterized by an opaque opalescent lens in the eyes, most cataracts are associated with age and are more common in people older than 50 years (but can develop at any age). Cataracts can be the result of injuries, UV radiation or deterioration of the protein over time, and this causes the cloud to cloud clouds. If left untreated, cataracts can eventually lead to severe vision loss.
Treatment: Fortunately, cataracts are a common eye problem that can be treated surgically. Whether surgery is required, depends on the degree of loss of vision and whether it depends on your quality of life and function.
Typically, the cornea (the transparent outer lens of the eye) has a dome shape, such as a ball. However, sometimes the collagen, which keeps the cornea in place, weakens, causing the cornea to become narrowed. This condition is called keratoconus. If treatment is not done early and quickly, it can lead to severe vision loss. If left untreated, many people will require corneal transplantation.
Treatment: Treatment usually begins with glasses. Contact lenses, which are usually heavy, breathable lenses, suggest strengthening the cornea and improving vision. In addition, cross-linking of corneal collagen is often effective in preventing progression, as well as intima (implants located beneath the surface of the cornea reduce conicity and improve vision). The last remedy is cornea transplantation.
3. Diabetic retinopathy
Diabetic retinopathy occurs because of long-term hyperglycemia associated with type 1 and type 2 diabetes, and can lead to blindness if left untreated. Excessive blood sugar levels can alter the blood vessels in the back of the eye, preventing the retina from getting the required amount of nutrients needed to maintain vision. People with type 1 or type 2 diabetes are at risk for diabetic retinopathy. However, the type of diabetes in a person, the frequency of fluctuations in blood sugar levels, the extent to which they control sugar, and the time during which they have diabetes can affect his / her risk.
Treatment: In most cases, laser surgery can prevent a significant loss of vision associated with diabetic retinopathy. The procedure, called laser photocoagulation, can seal or destroy blood vessels that grow or flow in the retina.
4. Macular degeneration
The main cause of this blindness is the damage to the macula, which is the area of the retina that senses light. Risk factors include: age, smoking, female and family history. Unfortunately, there are no known methods for treating macular degeneration. However, current treatments can slow the progression of the disease.
Treatment: Age-related macular degeneration can prevent severe vision loss or significantly slow the progression of the disease. There are several treatment options, including:
Anti-angiogenic drugs. These drugs are injected into the eye to prevent the formation of new blood vessels and the leakage of abnormal blood vessels into the eye.
Laser treatment. High-energy lasers can sometimes be used to destroy abnormal blood vessels that are actively growing.
Photodynamic laser treatment. Two-step treatment, in which a photosensitive drug is used to destroy abnormal blood vessels. The drug is injected into the bloodstream for absorption by abnormal blood vessels in the eye. A cold laser is then applied to the eye to activate the drug, causing damage to the abnormal blood vessel.
Vitamins C, E, β-carotene, zinc and copper can reduce the risk of vision loss in some patients with advanced age-related macular degeneration.
5. Refraction error
According to the National Eye Institute, refraction is the most common cause of vision problems. When light passes through the cornea and the lens, refraction of the eye occurs. Errors can occur due to the length of the eyeball, changes in the shape of the cornea, or the natural aging of the lens. Myopia, hyperopia and astigmatism are classified by mistake of refraction.
Treatment: the most common forms of treatment are glasses, contact lenses and surgery.
