If left undetected and untreated, vision problems in the elderly can lead to partial or complete vision loss. In fact, statistics reveal that 65% of those with visual impairment and 82% of those who are blind are over 50 years old.
To help you steer clear of serious eye problems later in life, below is a list of eye diseases that you need to watch out for as you age, plus information on diagnostic and treatment options.
Vision Problems in the Elderly
1. Age-related Macular Degeneration (AMD)
Age-related macular degeneration primarily affects the macula — a tiny portion found at the center of the retina and responsible for sharp central vision.
If you have AMD, you will have difficulties performing detail-oriented tasks such as reading, writing, driving, and identifying different shades of colors. Distorted, fuzzy, or shadowy central vision is an early sign of AMD.
In a major clinical study called The Age-Related Eye Disease Study (AREDS) done by the National Eye Institute (NEI), four factors stood out in increasing AMD risk:
- Age
- Race (Caucasian)
- Family history
- History of smoking
AMD can be classified into two types: dry and wet. Each type requires different treatment approaches.
It’s possible to detect early signs of AMD and slow down its progression through a comprehensive retinal exam.
2. Cataracts
In a healthy eye, the lenses are primarily crystal clear and flexible. As you age, the lenses become less flexible, and cloudy areas typically cover the entire lens inside your eye. This is what happens when you develop cataracts.
Half of Americans will develop cataracts by age 75. The earliest signs of cataracts include cloudy or blurred vision, poor night vision, and colors that may appear less vivid than they once did.
Lens replacement surgery is the only way to remove cataracts. It involves creating a small incision through which the natural lens is removed and replaced with a new, artificial lens.
3. Diabetic Eye Disease
Also known as diabetic retinopathy, diabetic eye disease results from damage to the blood vessels in the retina in people with diabetes. As a result, the blood vessels will either bleed or leak fluid. If left uncontrolled, this can lead to permanent vision loss.
Nerve damage affecting muscles that control eye movements may be present, too. Symptoms may include double vision and involuntary eye movements.
If you have an early-stage diabetic eye disease, you will be asked to control your blood sugar and cholesterol levels. Advanced stages require laser treatment and vitrectomy surgery.
4. Glaucoma
Glaucoma is a collective term for a group of related eye disorders that damage the optic nerve, which transmits information from the eye to the brain.
Glaucoma can be either open-angle or narrow-angle. Often, open-angle glaucoma has no symptoms, and vision stays normal.
The majority of glaucoma cases involve elevated intraocular pressure, leading to peripheral vision loss. Trouble seeing in dim light and difficulties navigating while walking are late symptoms of peripheral vision loss.
Glaucoma is diagnosed through a comprehensive dilated exam. Treatment is often aimed at reducing the amount of fluid produced by the eye or increasing the amount that drains from it. Glaucoma surgery may be recommended to increase the drainage of aqueous humor.
Besides aging, glaucoma risk is high among African-Americans and people with a family history of glaucoma.
5. Dry Eye Syndrome
Dry eye syndrome is a result of a chronic lack of sufficient moisture (oil, water, or mucus) on the eye’s surface. This lack of moisture and lubrication is often a result of the following:
- Insufficient production of tears
- Poor tear quality
Underlying causes and symptoms of dry eye syndrome can vary. The following are the most common symptoms:
- Burning sensation
- Gritty or sandy feeling in the eye
- Sore eyes
- Blurred vision
- Watery eyes due to excessive tearing
Dry eye management and treatment options include eye drops to relieve symptoms, anti-inflammatory medications, dietary changes, lid hygiene, and in-office procedures.
6. Low Vision
People with eye disease symptoms due to advancing age are more likely to have low vision. This condition makes daily tasks difficult because even with glasses, contact lenses, and medications, low vision symptoms cannot be reduced.
People with low vision can lead better lives and work safely with rehabilitation options such as:
- Spectacle-mounted magnifiers
- Lighted handheld magnifiers
- Digital desktop magnifiers
- Bioptic telescopes
- Software with text-to-speech and magnification features
Don’t Live with Age-related Vision Loss
Visual impairment among aging individuals takes many forms and can vary in severity. In most cases, your visual acuity score alone is not a good predictor of age-related vision problems. A comprehensive eye exam performed by knowledgeable and caring eye care professionals is crucial to maintaining your eyes’ optimal function throughout your golden years.
Don’t believe that getting old translates to vision loss? Maintaining healthier eyesight in your golden years is possible if you take proactive steps.
