Types and causes of blindness

In astigmatism, one eye creates an image of one side of the brain and the other eye creates a different image.

It means that two different images are being formed on the brain, the brain does not accept this in any case. Blurred vision is mostly seen in children but it can affect you at any stage of life. Blindness in children or older people can be caused by various medical conditions such as cerebral palsy or physical paralysis.

What is squint or cross eyes?

Cross-eyes, also known as ‘strabismus’, is a condition in which your eyes do not line up. In this the eyes look in different directions and each eye will focus on a different object.

Symptoms

In strabismus, the eyes may point inward or outward or focus in different directions, and signs of strabismus include: blurred vision, double vision, loss of depth perception, pain in the eyes or headache. Pain. These symptoms can be constant or only appear when you are tired or not feeling well.

Types of blindness

(1) Hypertropia: It occurs when the eyes turn upwards.

(2) Hypotropia: It occurs when the eyes turn downward.

(3) Esotropia: It occurs when the eyes turn inwards.

(4) Exotropia: It occurs when the eyes turn outwards.

Causes of blindness

Blindness is caused by nerve damage or when the muscles around your eyes don’t work together because some muscles are weakened by other muscles. When the brain receives a different visual message from each eye, it ignores the signals from your weaker eye. If the condition of the eyes is not good, it can make you blind.

Dandruff in children

Dandruff is common in children. Often the underlying cause is unknown. ‘Infantile esotropia’ is a special type of nearsightedness that appears in children in the first year. Sometimes blindness runs in families and is corrected with surgery. This squint occurs in children between the ages of two and five and is usually corrected with glasses. One type is “acquired blindness.” In this, children usually look at the imitation of someone with crooked eyes. It occurs between the ages of two and five years but is cured with regular use of glasses.

Medical condition

Blindness can occur in any part of life. This is usually due to physical disorders. For example, eye injury, cerebral palsy, physical paralysis etc. Allah has given us two eyes. When we look at an object, both eyes automatically turn towards that object. If for some reason the coordination of these two eyes is damaged, the disease of squint appears. Imbalance can usually be caused by any of the following three reasons:

(1) The mind could not maintain the balance of the movements of the two eyes.

(2) The performance of one eye becomes impaired due to any reason. For example, cataracts, macular degeneration, one eye being naturally weaker than the other, etc.

(3) One or more of the 12 muscles that control eye movements become diseased and do not work properly. For example, paralysis of an organ, maldevelopment of an organ, injury of an organ.

Disadvantages of blindness

Many times blindness leads to psychological confusion. Because the face becomes ugly. Children with muscle paralysis may unconsciously assume abnormal head and face positions. This position can lead to lifelong damage to the neck joints. Headache, dizziness, start moving words while reading, are common symptoms of this disease. Their presence affects the performance of children. Children are fascinated by studies. People start stealing from work for which they don’t even understand the reason.

It is curable in most patients. Treatment is related to the defect. If the eye function is poor and its ability to function can be improved in some way, it will cure the blindness. For example, cataract surgery should be done. If glasses are needed, then starting to use glasses will gradually correct the strabismus. Thus, it is often possible to improve the performance of muscles that are paralyzed or congenitally weak.
