What You Need Know about Diabetes and Eye Health

Diabetes can cause serious complications in the eyes, potentially leading to vision loss or even blindness if not properly managed. High blood sugar levels over time can damage the delicate blood vessels and tissues of the eye, resulting in a variety of eye conditions. In this article, you will learn everything you need to know about eyes health and diabetes.

What You Need Know about Diabetes and Eye Health

How Diabetes Affects the Eyes

The eyes are made up of several important parts that can be affected by diabetes:

• Iris: The colored part of the eye that regulates how much light enters.
• Lens: Helps focus light onto the retina for clear vision.
• Vitreous Humor: Gel-like substance inside the eye that helps maintain its shape.
• Retina: A light-sensitive layer that sends signals to the brain.
• Optic Nerve: Carries visual information from the retina to the brain.

Damage to these structures can cause long-term vision problems if not addressed early.

Common Diabetic Eye Conditions

People living with diabetes are at a higher risk for the following eye diseases:

• Diabetic Retinopathy: Damage to the blood vessels of the retina. It's the most common cause of vision loss in people with diabetes.
• Cataracts: Clouding of the eye’s natural lens, which can develop earlier in people with diabetes.
• Glaucoma: Increased eye pressure that can damage the optic nerve and lead to permanent vision loss.

When to Get an Eye Exam

Routine eye exams are essential for detecting early signs of eye damage—even before symptoms appear. Here’s how often you should be screened:

• Type 1 Diabetes: First eye exam 5 years after diagnosis, then yearly.
• Type 2 Diabetes: Eye exam at the time of diagnosis, then yearly.
• Pregnant Women with Diabetes: Before pregnancy or during the first trimester, followed by regular monitoring as advised by your doctor.

Warning Signs Not to Ignore

Seek immediate medical attention if you experience:

• Blurry or fluctuating vision
• Double vision
• Difficulty seeing at night
• Difficulty distinguishing colors
• Dry eyes
• Sudden vision loss

Prevention Tips

You can reduce your risk of diabetic eye complications with these simple steps:

• Keep your blood sugar in a healthy range.
• Control your blood pressure and cholesterol.
• Avoid smoking.
• Visit an eye care specialist regularly for check-ups.

Conclusion

Eye damage from diabetes can often be prevented or slowed with early detection and good blood sugar management. Prioritizing regular eye exams and managing your overall health are the best ways to preserve your vision.
