Blindness: Steps, Signs, Prevention, Treatment

Blindness is such a problem related to the loss of vision, which can not be cured with normal eyeglasses, contact lenses, medicines, and surgery. This situation negatively affects the everyday life of a person. In this state, the person does not see anything, even if it is not visible to light.

If you have some form of blindness, then your eyesight is in limited quantity, for example, inability to explain the difference in the size of the objects of different sizes. Full blindness means that you will not be able to see anything and you will only feel dark. If the thing is legal blindness – this is an American word, which means the patient’s eyesight, then its patient has to compromise with vision. A person with a healthy eye can see up to 200 feet, whereas the person with legal blindness can only see up to 20 feet.

Causes for long-term blindness include cataract, refractive errors, glaucoma, corneal opiate, age-related macular degeneration, childhood blindness, and diabetic retinopathy etc. Blindness is examined by visual acuity examination. Treatment of blindness is done on the basis of its cause, it can be treated medically or surgically.

Blindness stages

What are the steps of blindness?

The best way to measure vision loss is to see how much and how people are able to work their eyes. These levels can be clearly visible, visible in blurred, low vision, and complete blindness. The Vision Function is divided into 4 phases by the World Health Organization (WHO).

  • Normal
  • Medium vision loss
  • Serious sight loss
  • Blindness

The eyes of the person cannot be cured with medicines, operations, contact lenses and eyeglasses in the dark to severe levels of blindness.

Symptoms of blindness

What symptoms are perceived in blindness?

Suddenly, the failure to lose sight suddenly sometimes takes a few seconds or a few days. The vision either becomes completely blurred or completely eliminates. In some cases, the sight is affected by flashing light or the spot is visible in the spot.

Some part of the place we see during this problem or it looks completely blurred. In such a case, one eye is seen with the other eye and this process is done with both eyes so that it can be detected that the problem is in one eye or both.

Lack of sudden loss of sight is often painless, but it can also have problems like eye pain, redness, and headache. Any change in vision ability is serious in itself. Well, this change happened in a small part of the realm of view or it has been cured automatically.

Other symptoms that occur suddenly or both in the eyes include the following:

  • Feeling severe weakness in the body along with sight or pain in the eyes of the eye.
  • Loss of sight suddenly and without pain, sometimes experiencing vision loss in the morning
  • Difficulty looking after head injury
  • Difficulty adjusting in dim light
  • Difficulty focusing
  • Having pain with light and being too sensitive to light
  • Burning in the eyes, dryness in the eyes, swelling or scab
  • Blurred or two photos visible
  • Look at the circle of light around the things you are watching
  • Spotting spots in the viewing area
  • The blindness starts suddenly and completely unexpectedly
  • Sometimes it is very difficult to overcome, and with increasing time it becomes very fierce.
  • Take one hour to recover the problem yourself or in some cases less than an hour.

When should the doctor show up?

If you suddenly lose sight of sight, then go to the doctor immediately. Keep a friend or relative with you as a partner who can go with you to an emergency and stay there. Do not wait for your sight to be arranged to go to the doctor immediately. Many times, immediate treatment increases the chances of your sight coming back, but this outcome depends entirely on the cause responsible for your blindness. Treatment can include options such as surgery to medicines.

Due to blindness and risk

Why is blindness?

Getting hurt –

  • Direct injury to the eye, injuries to the bones or tissues around the eye, damages the eyes and can inhibit vision. However, it is not necessary that the cause of this injury is only an external object.
  • There may be vision loss due to any trauma caused by the head. The reason for this is that many veins pass from the head to the eyes and the nerves can be damaged by the trauma on the head. It is also possible in a slight injury to the head and also in any traumatic brain injury. (Read more Diabetic neuropathy)

Diseases of eyes described below can also cause blindness, such as:

Optic neuritis – This is a type of swelling in the eyes, which can partially be visible for some time or forever.

Retinitis pigmentosa – Retinitis pigmentosa is a result of any type of damage in the retina. In very rare cases, it is blinded by blindness.

  • Cataract – This causes blurred vision, it is quite common among older people.
  • Lazy Eye – It is also known as Amblyopia or Dim Vision. In this, the victim is unable to see the full details of the person or person being seen in front. Going forward can lead to blindness.
  • Tumors – Tumors that affect your retina or vein can also cause blindness.
  • Glaucoma – Glaucoma is meant to have four different conditions of the eyes that can damage the vein of your eyes. With the help of these nerves, the information of what you see reaches to the brain and we get to know what we saw.
  • Macular degeneration – destroys the part of your eye so that you can see an object in the detail. Generally, it affects older adults only.

If you are suffering from diabetes or stroke, there are full potentials that you can get into the grip of blindness. Other common complications due to birth defects, eye injuries, and eye surgery are also other common causes of blindness development.

There are three main reasons for losing sight of the sudden:

  1. Blurring in the transparent structures of the eye in general
  2. Abnormalities in the retina (light sensing structure behind the eye is called retina)
  3. Abnormalities in the vein that lead the sign of sight from the eye to the brain.

Risk factor –

The risk of blindness in people of the following classes is high:

  • Infants born prematurely
  • People taking the high dose of blood pressure medicines
  • Migraine headaches that have been family or hereditary disease
  • People with eye-related diseases such as macular degeneration and glaucoma
  • People with diabetes (read more – avoiding diabetes)
  • Patients whose eye surgery has occurred
  • People who work in contact with sharp-edged objects or toxic chemicals
  • People with stroke
  • People who have communication problems such as rigidity in the arteries, swelling and burning sensation in the blood vessels.

Avoiding blindness

How to prevent blindness?

With the help of a healthy behavior, temporary blindness can be prevented due to the sudden flow of blood in the eye, as well as prevent stroke and other health-related problems.

  • Talk to your doctor about what you should do to get a healthy lifestyle.
  • Keep your blood pressure, blood sugar and cholesterol level diet, exercise and if medicines are written, help with them.
  • Eat a healthy diet and maintain a healthy weight.
  • Keep fit with the kind of exercises you are right for
  • Learn how to manage stress
  • If you drink beedi or cigarettes, try to leave it. You can also take help from a doctor to quit smoking.
  • If you want to drink alcohol, first ask the doctor how much alcohol is safe for you.

Blindness test

How is blindness checked?

Many evaluations made to examine the disease help to determine the root causes of vision loss. For this you should know the following:

  • Basic Testing – Fundamental exam techniques are important to confirm the proper investigation. The first thing in this test is to determine the best – the right visual acuity.

o The doctor will first carefully examine the sharpness of his vision by asking the patient to read some letters on a chart. In this test, one eye is closed and one is asked to read and then both are asked to open and read.

o The pinhole test is important for reducing possible causes of vision loss. The pinhole is a shield of the eye, which has several small holes. It allows light rays to reach the retina without interfering with optical problems in the eyes. This is an excellent way to clarify the difference between problems caused by eye lenses and other problems.

o It is also tested on both eyes of the patient in different ways than how they look different colors from both eyes.

  • Pupil Testing – When evaluating the loss of the pupil, the reaction of the pupil is seen, it is also known that what is caused by the lightening of the victim and healthy eye, it is a special pupillary defect.
  • Vision area – To know the extent of vision loss and its patterns, it is necessary to test the visual field (vision field).
  • Funds testing – Most of the disorders associated with retina are so serious that they can cause vision loss. These disorders are visible during the careless retina test.
  • Lab Testing – Laboratory tests may be necessary depending on suspected causes of vision loss. People who have been over 55 years old and have suddenly been blinded, they should get CBC, platelet count, ER (Erythrocyte sedimentation rate) and C reactive protein test. Screening for hyperlipidemia and diabetes is also useful for finding cardiovascular risk factors. Also, these office blood pressure measurements are also very useful for patients who have suddenly been blindness.
  • Further investigation – Additional testing may also be required, including optical coherence tomography, fluorescein angiography, neuroimaging, carotid Doppler ultrasonography, echocardiography, or Temporal artery biopsy and so on. Although it depends on the cause of sight loss.

Treatment of blindness

How can blindness be treated?

The blindness is treated only on the basis of reason. If the treatment is started quickly, the loss of vision can be reduced. Vision loss due to eye-related problems can be corrected with the help of drops, medicines or surgery.

  • Steroids can be used if the cause of vision loss is swelling and burning.
  • If sudden blockage of blood vessels is causing vision loss, attention should be given to treating blood flow properly and smooth as soon as possible.
  • If you have severely blocked a blood vessel in your neck, you may need surgery to correct it.
  • The condition of blindness due to inflammation, burning, and infection can be corrected with the help of medicines and some types of eye drops.
  • The condition of the blindness due to the lack of nutrition can be corrected by changing the diet.
  • In situations where the eyes can not properly illuminate the face, due to which the front object is not visible, a suitable glasses can be provided to the patient to treat this condition.
  • High cholesterol, high blood pressure, and diabetes can be controlled by diet and medicines. If you smoke, it is very important that you leave it.

Most people are blind due to cataract. Cataract surgery is done in these patients and in most cases, the vision is returned. Typically, an intraocular lens (IOL) is removed by removing the natural opaque lens from the eye.

Although vision loss can occur at any age, most of the problem is in adults only. Blindness like any other major life event can bring feelings of loneliness, compulsion, anxiety, and depression. In this case, the doctors also give counseling to the blindness of the blindness, and at the same time, they can refer them further on the basis of their needs so that there is no depression of any kind in the patient. Those who have complete blindness should definitely be motivated to take counseling.
