Our eyes, like all other body parts, become more susceptible to disease as we age. The most common vision-related problems in older adults are glaucoma and cataracts. In fact, these are two of the most common causes of vision loss in the world.
However, few people understand how they differ and affect eyesight. Learn the key differences and crucial information about glaucoma and cataracts to ensure you're well-informed about your eye health.
Glaucoma vs. Cataracts
Glaucoma is an eye disease caused by increased pressure in the eyes. It steals away eyesight with very few or no symptoms, and once lost, vision cannot be restored. That makes early detection crucial.
A cataract is an age-related clouding of the lens of the eye. Just like with a camera, our eyes contain a lens to help us to focus on things whether they are nearby or far away. To work well, the lens must be clear. As we age, the lens of our eye gradually becomes cloudy. This type of vision loss can be more gradual. While it can seem similar to glaucoma, patients won’t be able to tell which condition they have without a proper eye exam.
Risk Factors for Cataracts and Glaucoma
Cataracts develop due to aging, but they can also be caused by a history of eye injuries or underlying health conditions. Recognizable symptoms of cataracts include blurry vision, difficulty seeing at night, dull vision with fading or yellowing of colors, the perception of halos around lights, and frequent changes in glasses prescription.
Glaucoma risk factors include age, race, family history and underlying health conditions, like diabetes. There are several types of glaucoma. One common type of glaucoma is primary open-angle glaucoma, which can lead to blind spots in your side vision. Angle-closure glaucoma can present with sudden vision loss, headaches and pain. Glaucoma can only be prevented through early diagnosis and prompt treatment.
Treatments for Cataracts and Glaucoma
A key difference between the two conditions pertains to treatment options. Cataracts can usually be removed through cataract surgery, allowing the patient to see clearly again. On the other hand, glaucoma symptoms can only be prevented, not reversed.
Glaucoma can lead to irreversible blindness. That’s why patients who notice any changes in their vision should get an eye exam right away.
Does Cataract Surgery Help Glaucoma?
Cataract surgery is one of the most commonly performed procedures in the world, proven to be safe, fast, and effective. Thanks to advanced corrective lens technology, many patients see better after surgery than they ever did before.
What many patients don’t realize is that cataract surgery can help improve glaucoma symptoms as well. That’s because cataract surgery can lower high eye pressure. This is a big relief for many patients who are often unsure whether they can have cataract surgery with glaucoma. Some patients even have cataract surgery and a type of glaucoma surgery in a combination procedure.
