If you’re living with diabetes, you’re likely aware of the importance of managing blood sugar levels to avoid complications. However, one area often overlooked is how high blood sugar can impact your eyes. So, how does diabetes affect your eyes? Quite significantly, in fact. Diabetes can lead to a range of serious eye conditions, collectively known as diabetic eye disease, that may result in vision loss if not properly managed.
In this article, we explore how diabetes impacts your vision, with a focus on Diabetic Retinopathy, prevention tips, and available treatment for diabetic eye disease.
Understanding the Link Between Diabetes and Vision
How High Blood Sugar Affects the Eyes
When blood glucose levels are consistently elevated, it can cause damage to the tiny blood vessels in your eyes. These vessels are crucial for nourishing the retina, the light-sensitive tissue at the back of your eye. Over time, high sugar levels can cause these vessels to swell, leak or close off entirely, disrupting the retina’s function and leading to diabetic eye disease.
This is why regular eye examinations are critical for anyone with diabetes. If you’re due for an eye test, visit Clear Vision Optical or book an appointment online.
What is Diabetic Retinopathy?
Diabetic Retinopathy is one of the most common and serious complications of diabetes affecting the eyes. It occurs when the retinal blood vessels become damaged due to prolonged high blood sugar levels.
Stages and Symptoms
There are two main stages of Diabetic Retinopathy:
- Non-proliferative diabetic retinopathy (NPDR): In its early stages, blood vessels weaken, causing tiny bulges (microaneurysms) that may leak fluid.
- Proliferative diabetic retinopathy (PDR): In more advanced stages, new abnormal blood vessels grow, which can bleed into the eye and increase the risk of retinal detachment.
Early diabetic eye disease often presents no symptoms, making regular eye checks vital. As it progresses, you might notice blurred vision, floaters, or even sudden vision loss.
Other Common Diabetic Eye Conditions
In addition to Diabetic Retinopathy, other conditions can develop as a result of diabetes:
- Diabetic Macular Oedema (DMO): A build-up of fluid in the macula, the part of the retina responsible for sharp central vision.
- Cataracts: People with diabetes are more likely to develop cataracts at a younger age.
- Glaucoma: High intraocular pressure can damage the optic nerve, especially in those with diabetes.
All of these fall under the umbrella of diabetic eye disease and require monitoring and management.
Symptoms: What to Look Out For
Early detection is key. Be on the lookout for:
- Blurry or fluctuating vision
- Dark or empty areas in your vision
- Spots or floaters
- Trouble seeing at night
- Sudden vision loss
These symptoms may be signs of Diabetic Retinopathy or another form of diabetic eye disease. Don’t wait for symptoms to appear, schedule regular eye exams to catch problems before they progress.
Who is at Risk?
Risk Factors for Diabetic Eye Disease
Anyone with diabetes type 1, type 2, or gestational is at risk of developing eye complications. However, the risk increases with:
- Longer duration of diabetes
- Poor blood glucose control
- High blood pressure or cholesterol
- Smoking
- Being over 40 years of age
This is why it’s strongly recommended that people with diabetes have comprehensive eye exams at least once a year. At Clear Vision Optical, we offer thorough eye checks using advanced diagnostic tools.
Preventing and Managing Diabetic Eye Disease
Tips for Prevention
The good news is that proactive management can greatly reduce your risk. Here’s how:
- Keep blood glucose, cholesterol, and blood pressure under control
- Follow a balanced diet and exercise regularly
- Avoid smoking
- Attend annual eye exams, even if you feel fine
These actions help prevent and delay the onset of diabetic eye disease, and protect your long-term vision.
Treatment for Diabetic Eye Disease
When complications do occur, there are several options available for the treatment of diabetic eye disease, depending on the severity and specific condition.
Available Treatments
- Laser Therapy: Used to seal leaking blood vessels or shrink abnormal vessels.
- Anti-VEGF Injections: Help reduce swelling in the retina and slow disease progression.
- Vitrectomy: Surgical removal of blood or scar tissue from the eye, often used in advanced cases.
At Clear Vision Optical, we work closely with ophthalmologists to coordinate referrals for advanced treatment for diabetic eye disease while continuing to monitor your condition in-practice.
