5 Leading Causes of Blindness in Elderly People

Most Common Causes of Blindness in Aging Adults in Fort Myers, FL

As people age, their eyesight often diminishes. Certain health conditions can cause blurred vision, double vision, diminished peripheral vision, and even total blindness. Here are five leading causes of blindness in the elderly and how you can help your aging loved one manage these vision issues.

1. Glaucoma

Glaucoma refers to elevated eye pressure. The two types of glaucoma are open-angle glaucoma and closed-angle glaucoma. Open-angle glaucoma is more common, and while both types can lead to blindness in the elderly, closed-angle glaucoma generally causes more severe symptoms, including intense eye pain, ocular redness, headaches, and sometimes nausea and vomiting. Special eye drops can lower eye pressure, but they do little to boost vision. If your loved one complains of eye pain or vision loss, make an appointment with an eye doctor. If eye drops are prescribed, assist your loved one with applying the drops to make sure the medication gets into the eye and the tip of the bottle doesn’t touch the eye’s surface.

2. Diabetic Retinopathy

Poorly managed or long-term diabetes can raise the risk of blindness in seniors. Diabetes can cause blood vessel damage, including damage to the small blood vessels of the retina behind the eye. While laser surgery can slow the progression of diabetic retinopathy, it may not enhance vision. You can help your loved one reduce the risk of retinal damage related to diabetes by making sure he or she takes all prescribed medications, follows the proper diet, gets daily exercise, avoids excess weight, and keeps all scheduled medical appointments. 

Some seniors with diabetes may find it challenging to manage their blood sugar levels on their own. Living with serious health conditions can make it challenging for seniors to age in place. However, they can maintain a higher quality of life with the help of professional live-in care. Fort Myers seniors can benefit from assistance with meal prep, bathing, transportation to the doctor’s office, medication reminders, and much more.

3. Strokes

Cerebral vascular accidents, or strokes, can lead to partial or total blindness. The risk of strokes increases as people age, especially if they have preexisting medical conditions such as high blood pressure, diabetes, or heart disease. To reduce your loved one’s risk of a stroke and subsequent blindness, monitor his or her salt intake to prevent sodium-related hypertension. Also, if your loved one smokes or drinks excessive amounts of alcohol, encourage quitting because both of these lifestyle choices can raise blood pressure, cause cardiac arrhythmia, and increase the risk of heart attacks and strokes.

4. Cataracts

Cataracts refer to a clouding or opacity of the eye’s natural lens. With cataracts, vision is often dim, blurred, cloudy, or hazy, and colors sometimes appear dull. While cataracts don’t cause symptoms such as pain, redness, or burning sensations, they can lead to blindness if not treated. A stronger eyeglass prescription can minimally increase vision. While new glasses can help, the only permanent treatment option is the surgical removal of the cataract and replacing the eye’s natural lens with an intraocular implant.

Seniors who have surgery to remove cataracts may find daily tasks challenging as they recover, and a professional caregiver can be a great asset. The type of in-home care seniors need can vary. Some need assistance a few hours a day, while others require more extensive around-the-clock assistance. At Home Care Assistance, we tailor our care plans based on each senior’s individual care needs, and the plans can be adjusted at any time.

5. Age-Related Macular Degeneration

As people get older, the risk of age-related macular degeneration, or damage to the eye’s macula, rises. Depending on the severity of the condition, symptoms of age-related macular degeneration can range from mildly blurred vision and depth perception problems to total blindness. Laser surgery can sometimes slow the progression of macular degeneration, but total restoration of visual function is rare.

Blindness can have a major effect on seniors’ ability to perform everyday tasks on their own, but help is just a phone call away.
