Age-Related Eye Diseases (AREDs)
You Should Consult with a Doctor:
Cataract, Macular Degeneration, and Retinal Vascular Occlusion

We take it for granted that our vision gets dimmer as we age. However, aging can also bring about more serious eye diseases that require urgent intervention.

Cataract: The Most Common Age-Related Eye Disease

Cataracts are quite commonplace today. This disease makes the eye lens look cloudy, and can be caused by other medical conditions, such as diabetes and trauma. However, most cases are caused by aging. An ophthalmologist of HanGil Eye Hospital also points out that symptoms of a cataract include blurry vision (the disappearance of the outlines of objects in one’s vision) and day blindness (hemeralopia). Cataracts can be removed surgically. If you have any of these symptoms, consult a specialist as soon as possible.

Macular Degeneration: A Major Cause of Blindness

The macula lutea is a collection of visual cells and nerves behind the retina. It is the part of the eye that receives light and renders the images of objects seen. Damage to the macula lutea can cause various complications, including the loss of vision. Age-related macular degeneration (AMD) is the most common form of damage. Extended exposure to sunlight, obesity, smoking, hypertension, hyperlipidemia, and family history are also other factors.
If you are experiencing a sudden decline in vision and objects appear to you as if they had been crumpled or erased on one side, you should see a doctor immediately. You can also do a simple test of covering one eye and gazing at objects like a checkerboard, pavements, a calendar, or bathroom tiles. If you see the lines resembling waves or are partially erased, you likely have a case of macular degeneration.

Tips for Preventing Macular Degeneration

- Quit smoking.
- Eat healthy amounts of fruits, vegetables, and fish daily.
- Refrain from eating food that raises your triglyceride levels.
- Maintain a healthy weight and exercise regularly.
- Get regular checkups if your family’s medical history includes this disease.
- Take vitamins and minerals.

A Stroke of the Eye: Retinal Vascular Occlusion

A stroke occurs when a blood vessel is blocked or when it contracts/expands, thereby reducing blood flow to the brain. Retinal vascular occlusion (RVO) is similar to a stroke in that it damages the retina and affects vision when any of the retinal arteries or veins are blocked.
People who experience a sudden darkening of their vision without experiencing any preceding pain and get better after several minutes or people whose vision of one eye getting much worse than that of the other should doubt the RVO and see a doctor immediately. At times, the hemorrhage in the vitreous body can also cause floaters.
According to HanGil Eye Hospital, the RVO is associated with diseases that have cardiovascular symptoms, such as arteriosclerosis, diabetes, and hypertension. They especially caution the elderly, who are more likely to experience these symptoms. RVO is easy to detect, prevent, and treat if you get regular eye exams.
