In general, blurry eyes indicate you have common visual acuity problems, such as minus or plus eyes, which can be corrected by wearing glasses or contact lenses. However, you should consult a doctor if blurry vision only occurs in the one eye. This condition could be a symptom of central serous chorioretinopathy (CSCR).
An Overview Of Central Serous Chorioretinopathy (CSCR)
Central serous chorioretinopathy (CSCR) aka central serous retinopathy is visual impairment due to leakage of fluid from the layer of tissue under the retina (choroid). The fluid then seeps and accumulates in the retinal layer. The accumulation of fluid causes swelling in the retinal layer.
Fluid that accumulates in the retinal layer causes visual disturbances in the form of changes in the shape of objects from the original shape of objects that should be seen. CSCR usually only makes one eye blurry. Other symptoms that can accompany are:
- The black area is right in the center of vision
- Straight lines that become crooked, wavy
- Objects appear smaller than their original size
- Objects appear farther away than they really are
- Things that are white become yellowish
Blurred or blurred eyes due to CSCR are divided into two types, namely acute and chronic. Acute CSCR occurs suddenly and lasts a short time.
Usually, acute CSCR resolves on its own when the fluid is finally reabsorbed within 2–6 months. However, if this acute phase occurs repeatedly, CSCR can develop into a chronic condition with more pronounced visual disturbances.
In the chronic phase, fluid buildup persists for more than 6 months and cannot be reabsorbed without treatment. If left unchecked, the eye affected by CSCR, either one or both eyes, is at risk of total vision loss.
What Causes One-Sided Blur In CSCR?
The exact cause of CSCR is not known, but there are several things that are suspected to be involved as a cause:
- Genetic alias congenital eye disorders. At least 50% of CSCR sufferers have a family who also suffers from the same thing.
- High blood pressure (hypertension) can increase your risk of developing blurred vision due to CSCR by up to 2.2 times.
- Use of corticosteroids (dexamethasone, methylprednisolone, etc.).
- Competitive, aggressive, and temperamental characteristics and attitudes
- Sleep disturbances increase the risk of CSCR by up to 22%.
Causes Of Blurry Eyes Other Than CSCR
Apart from CSCR, there are other health conditions that can cause your eyes to be farsighted. Some of them are:
1. Cataract
Cataracts are one of the most common eye disorders. This condition usually affects both eyes. However, sometimes one part of the eye experiences a decrease in vision that is worse than the other eye.
Cataracts occur when there are smudges or opaque spots that cover the lens of the eye so that light entering the eye is not focused properly. As a result, vision becomes blurred or ghosted.
2. Glaucoma
Glaucoma is a disease caused by damage to the optic nerve. This disease is caused by an increase in eye pressure, so that the optic nerve is compressed and the ability to see gets worse.
Because glaucoma can only affect one eye, it is possible that one eye blurry 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 glaucoma can damage both eyes within 5-10 years.
3. Eye infection
Eye infections have the potential to trigger your eyes 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 blurred vision, 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 blurry eyes 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 decreased vision.
How To Treat Blurry Eyes
How to treat farsighted eyes usually depends on the main cause. For blurred vision caused by CSCR, especially chronic in nature, the treatment provided includes:
- Laser photocoagulation
- Anti-VEGF injection (bevacizumab)
- Eye drops, such as nepafenac
- Oral medications (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 already severe enough, you may be advised to undergo cataract surgery.
Therefore, immediately consult a doctor if you experience vision problems in one eye. This is important so that you get the appropriate treatment for your eye health condition.
