One-sided blurry eye, what is the cause? dangerous?

In general, blurry eyes indicate that you have a common visual acuity problem - such as minus or plus eyes - which can be corrected by wearing glasses or contact lenses. However, you should check with your doctor if blurred vision only occurs in the other eye. It could be that this condition is a symptom central serous chorioretinopathy (CSCR).

At a glance

Central serous chorioretinopathy (CSCR) aka central serous retinopathy is a visual disturbance due to leakage of fluid from the tissue layer under the retina (choroid). The fluid then seeps and accumulates in the lining of the retina.

The buildup of fluid causes swelling in the lining of the retina. Fluid that accumulates in the retina layer causes visual disturbances in the form of changes in the shape of objects from the original shape of what they should be seen.

CSCR usually only creates one-sided blur. Other symptoms that can accompany it are:

• Black area right in the center of vision
• A straight line that becomes crooked, wavy
• Objects appear smaller than their original size
• Objects become visible further away from their true distance
• White objects look yellowish

There are two types of eyes that are blurry or blurred due to CSCR, namely acute and chronic. Acute CSCR occurs suddenly and lasts a short time. Usually, acute CSCR resolves on its own when the fluid is eventually reabsorbed within 2–6 months.

However, if this acute phase occurs repeatedly, CSCR can develop into a chronic condition with more pronounced visual impairment symptoms. In the chronic phase, fluid buildup lasts more than 6 months and cannot be reabsorbed without treatment.

If left untreated, the affected eye, either one or both eyes, is at risk of total vision loss.

What causes one-sided blur on CSCR?

The exact cause of CSCR is not yet known, but there are several things that are thought to have contributed to the cause:

• Genetic aka congenital eye disorder. At least 50% of people with CSCR have families that suffer from the same thing.
• High blood pressure (hypertension) can increase your risk of having one-sided blurred eye due to CSCR up to 2.2 times.
• Use corticosteroids (dexamethasone, methylprednisolone, etc.).
• Characteristics and attitudes competitive, aggressive, and temperamental
• Sleep disturbance increases the risk of CSCR by up to 22%.

The cause of the eye blur in addition to CSCR

Apart from CSCR, there are also other health conditions that can cause your eyes to become blindfolded. Some of them are:

1. Cataracts

Cataracts are a common eye disorder. This condition usually affects both parts of the eye. However, sometimes one part of the eye has a decrease in vision that is worse than the other eye.

Cataracts occur when there are blemishes or blemishes that cover the lens of the eye, so that the light that enters the eye is not focused properly. As a result, the vision becomes blurry or hazy.

2. Glaucoma

Glaucoma is a disease caused by damage to the optic nerve. This disease is caused by increased pressure on the eyeball, so that the optic nerve is compressed and the ability to see is getting worse.

Because glaucoma can only affect one eye, it is possible that one eye blur is a sign of glaucoma. However, most cases of glaucoma actually occur in both eyes.

If glaucoma only affects one eye, there is a 40-80% chance that it can damage both eyes in 5-10 years.

3. Eye infection

An eye infection has the potential to trigger your eye to become blurry or blurry. Infection can affect any part of the eye, one of which is conjunctivitis which affects the conjunctiva of the eye.

This condition is usually caused by a bacterial, viral, or allergen infection. Not only does the vision become blurred, conjunctivitis also causes red, itchy, and watery eyes.

These symptoms can affect only one eye or both of your eyes.

4. Macular degeneration

Macular degeneration is a common cause of blindness in the elderly. This condition occurs when a part of the retina called the macula is damaged. As a result of macular degeneration, central or middle vision will decrease.

According to the BrightFocus website, a person may develop macular degeneration in only one eye. However, as the disease progresses, over time both eyes will experience a decrease in vision.

How to treat one-sided blurry eye

How to treat myopic eyes usually depends on the main cause.

For one-sided blurred eye caused by CSCR, especially chronic ones, the treatment given includes:

• Laser photocoagulation
• Anti-VEGF injection (bevacizumab)
• Eye drops, such as nepafenac
• Oral medicine (acetazolamide, aspirin, spironolactone)

Another type of treatment if the blurry eye is caused by another disease. For example, if your condition is related to cataracts that are severe enough, you may be advised to undergo cataract surgery.

Therefore, immediately consult a doctor when you experience vision problems in one eye. This is important so that you get treatment according to your eye health condition.
