Vision Loss

Vision Loss can be various ways. But, today we are going to discuss about 5 Harmful Diseases That Are Responsible For Your Vision Loss.

Diseases That Are Responsible For Your Vision Loss 

Diseases That Are Responsible For Your Vision Loss 

The most hazardous eye conditions might develop for a number of reasons. Let’s take a look at the types of those diseases one by one that are reliable for Vision Loss:-

1. Diabetic Retinopathy

Diabetic Retinopathy

If the parity of diabetes is upper than usual, multiple organs and functionality of the body are harmed. Optical information goes to the optic nerve via the retina of the eyes. When blood sugar rises, the narrow blood vessels in the retina are damaged, tearing the narrow blood vessels. Blood and other fluids leak from there. As a result, the tissue of the retina swells. Vision becomes blurred. One of the most damaging aspects of diabetes is retinopathy, which can lead to blindness or Vision Loss.

This damage starts out very subtle but progresses over time. The affliction of diabetes for a long period of time enlarges the danger of this disease. As soon as possible the issue is tracked out and treated, the lower the risk of eyesight issue or Vision Loss. The way to prevent this disease is to control diabetes so that blood sugar levels do not rise Because of that:

• Regularly take diabetes medicines and insulin.

• Have a healthy diet. Foods that increase blood sugar levels should be ignored.

• Develop the habit of physical exercise according to your daily capacity.

• Quit drinking and smoking.

There should be enough fresh fruits and vegetables in the diet. Eye health is deeply dependent on diet. September 2019 incident In Britain, a teenager develops sudden blindness. The study revealed that the boy had eaten nothing but potato chips, French fries, and processed pork products for several years. A case like this is an extreme example of optic neuropathy. A hygienic diet is also necessary for eye health or prevent Vision Loss.

In the therapy of this issue, straight injection into the eye can stave off damage to the blood vein and halt the combustibility. If a bit of the retina is ripped out, it can be mending through laser treatment. Surgery becomes essential in the extremely advanced steps of diabetic retinopathy. Surgery involves replanting the vitreous humor from the back of the eye and reattaching the detached retina. Diabetic Retinopathy is one of the mist crucial diseases of Vision Loss.

2. Glaucoma


Unconsciously, the patient’s widening vision shifts from peripheral to focused. The patient may see clearly at a great distance, but it is like looking through a round tube. I can’t see things around me. Difficulty driving. Syndromes are not detectable; hence it is too tardy to seize them.

The reason for the sickness is destruction to the optic nerve. The cause of damage is intraocular pressure inside the eye. The fluid inside the eyeball is called aqueous humor. When its pressure reaches a certain level, the pressure on the optic nerve causes Vision Loss.

Prominent ophthalmologist Dr. Sumit Chowdhury said, “While the patient understands the matter, the damage is already done. If the eyesight lessens and the patient sees dim mish in the eyes, then they have to understand that the main eyesight also began to be harmed. Highly weak eyesight, pain, and redness in the eyes are attributes of a specific type of glaucoma. Frequently changes in the foresight of the glasses in a short time can also be a symptom of glaucoma.

It is often seen that, in those person who have high minus lenses power in her/his eyes, any kinds of injury, type 2 diabetes, migraine, thyroid, injury to the eyes, anyone in the family diagnosed with glaucoma, obesity, even if they are taking steroids for a long times, this disease the risk is elevated.

About the method of diagnosis Dr. Chowdhury said, “First the patient’s eye pressure, or IOP, is checked. Gonioscope is used to assess the inner angle of the eye, also known as the angle of the anterior chamber, after viewing the IOP. By this definition, glaucoma is divided into open-angle and closed-angle glaucoma. An open angle means that the pressure of the aqueous humor inside the eye increases, but the fluid exit is open. In the case of a closed angle, this path is closed. The eyes are often painful and red, and the glasses have to be changed due to frequent movement.”

After looking at the angle, the damage to the optic nerve is seen. Automated perimeter can measure how much visual field has been lost. OCT, or optical coherence tomography, is sometimes performed if not detected at perimeter or for confirmation. In many cases, however, optic nerve damage may occur despite normal or low IOP or intraocular pressure. In all these cases, the disease cannot be detected without automated perimeter or OCT.

Dr. Chowdhury also said, ”The sooner the disease is detected, the sooner damage can be stopped. Some of the vision that is lost does not come back, but the remaining vision can be preserved. In this method, the doctor only gives the prescription; the rest depends on the vigilance of the patient and his family.

Eye examinations should be done at regular intervals, along with regular use of medicine. Only then can blindness due to glaucoma be prevented.” Glaucoma is also a dangerous disease of Vision Loss or eyesight issue.



Cataracts are also a harmful disease of eyesight issue or Vision Loss. Cataracts are the loss of clarity of the eye’s own natural lens. Protein buildup on the lens results in clouding. And, for the reason the light rays can’t reach straight to the retina. It is very normal and it occurs to everyone. 

Almost all people develop this disease in old age. At least after the average age of 65–70 years, it is normal for this disease to appear in one or both eyes. Though this disease is very rare, but it can also be noticed in children. Wherefore, the disease is so ordinary, it can be reckoned the largest reason of blindness if not treated.

The signs of this disease are increasing Vision Loss, foggy or blurred eyesight; eyesight issues even with sunglasses or glasses, occasionally dual vision, trouble to detect colors, and expanded blurred eyesight in the evening time.

There is no other way to shut it. However, smoking damages overall eye health cause of Vision Loss. Therefore, not smoking, protecting the eyes from ultraviolet ray’s as much as possible, and controlling or preventing diabetes can greatly delay the onset of this disease. Surgery is the primary treatment for this problem. Ninety percent of people regain improved vision after surgery.

Dr. Chowdhury informs us, “The retina of the eye is like the film of a camera. If the retina is healthy and not weakened, then the light coming through the clear lens will produce a clear reflection on the retina after cataract surgery.

As a result, full vision will return. Paedomorphic glaucoma is a condition in which protein deposits lead to the lens becoming mushy and swollen if treatment is delayed. Or it can be a sturdy cracked and liquid, cacao dependent hagocyticagocytic glaucoma. It can conduct to blindness or Vision Loss, If this glaucoma is not treated due time. So, it is secure to have cataract surgery in due time.

4.Age-related Macular Degeneration

4.Age-related Macular Degeneration

Usually occurs over 50 years of age. The portion of the retina that manages the main vision of the eye and permits the eye to see directly on a thing is called the macula. As we age, this part deteriorates and eyesight starts to decrease. This degeneration is of two types: dry and wet. In dry degeneration, the macula becomes progressively dry and thin and cannot function properly. Most degeneration is of this type. In wet degeneration, central vision is obstructed when fluid leaks out of newly formed blood vessels under the macula. In this case, the loss of vision is more rapid.

Symptoms of this problem are difficulty seeing objects clearly, objects’ shapes and sizes appearing distorted or wavy, straight spots appearing wavy, colors not clearly perceived, and the central part of vision appearing dark or blank. If noticed any of these must consult an eye specialist. With right nursing or treatment, harm can be stopped or prevented.

To keep good eye health or prevent Vision Loss, it is very crucial to quit smoking if you have a routine and healthy diet. A healthy diet which is rich in vitamins is efficient to stop the procedure of Vision Loss to a huge extent.

Intraocular injections are sometimes used to treat age-related macular degeneration. The injection works to break up any abnormal blood vessels that form and drain any fluid that accumulates in the macula dense. If necessary, although in rare cases, the doctor may decide to perform surgery for this disease.

5.Sudden Injury to the Eye

Sudden Injury to the Eye

Severe eye injuries can cause Vision Loss. The severity of the danger depends on where critical parts like the choroid, retina, cornea, conjunctiva, iris, and pupil are injured on the surface of the eye. Dr. Chowdhury said, “There are two types of injuries: blunt trauma, maybe trauma to the outer bone of the eye, soreness, or fracture. Another is sharp trauma. Cut somewhere in the eye, muscle injury, blood clot or hemorrhage, etc. If the eye is injured, the first thing to see is the depth of the injury.

How many layers of the eye are injured? A lot depends on how quickly he is brought to the eye department of the hospital after the injury and what facilities are there for treatment.” If a hit causes bleeding from the optic sinew or retina of the eye, eyesight is temporarily ruined. But if correct treatment does not occur in due time, it will be risky to repair the harm. In that case, Vision Loss can be permanently occur.

That’s why, when driving or working with any harmful chemicals, you have to be very careful about your eyes.



Eye is one of the most important organs of the human body. Today we have learned about 5 most harmful diseases that are responsible for eyesight problems or Vision Loss. We have to be more conscious about these diseases as well as harmful impacts of these diseases in our eyes.
