1 Answer:

Good evening, thanks for the question

According to a national survey, 80% of the causes of blindness in adults and the elderly are due to cataracts. Especially if there are complaints of white vision in elderly patients.

Cataract is a clouding of the lens that causes a sharp decrease in vision (vision). As we get older, the protein in the lens will clot and slowly make the lens cloudy and foggy. This causes vision to be blurred and unclear.

Cataracts are most often associated with the process of lens degeneration in patients over the age of 40 years (senile cataract). In addition to senile cataracts, cataracts can also occur due to complications of glaucoma, eye trauma, and systemic disorders such as diabetes mellitus, history of steroid drug use, and others.

Patients present with complaints of vision declining slowly as covered by smoke / mist. Complaints accompanied by increased size of the glasses, glare, and difficulty reading.
Risk Factors:

1. Age more than 40 years

2. History of systemic diseases, such as diabetes mellitus

3. Routine use of steroid eye drops

4. The habit of smoking and sun exposure

To make a diagnosis of cataracts, the doctor will check the sharpness of vision, examination of the shadow test, as well as examination of lens turbidity either directly on cataracts that have matured or using an ophthalmoscope. The definitive treatment of this disorder is surgery.

The second most common cause after cataract is glaucoma pressure increase in the eyeball. Glaucoma is a group of eye diseases that are generally characterized by nerve damage and loss of visual fields that are progressive and are associated with various risk factors, especially high intraocular pressure (IOP).

Blindness due to glaucoma cannot be cured, but in most cases glaucoma can be controlled. Generally glaucoma sufferers are elderly, especially those who have risks. Nearly half of glaucoma sufferers are unaware that they have the disease.

Risk Factors:

1. Age 40 years or more

2. There are family members suffering from glaucoma

3. People with myopia, cardiovascular disease, hypertension, hypotension, vasospasm, diabetes mellitus, and migraine

4. In secondary glaucoma, a history of routine use of steroids, or a history of trauma to the eye can be found.
To establish the possible cause of blindness due to glaucoma, the doctor will conduct a sharp examination of vision, visual field examination, examination of intraocular pressure, and fundoscopic examination to assess the visual nerve.

Glaucoma treatment aims to control the pressure in the ball with the use of drugs.

Other causes such as macular degeneration related to old age can also be the cause, therefore consult for a more detailed examination.

While what can be done to reduce symptoms include:

Protect your eyes from dust exposure Using eye glasses when outside the home Using artificial eye drops Avoiding eye fatigue So, hopefully this information can be useful
