Diabetes & Vision Health – Understanding Diabetic Eye Care and Risks

Diabetes is a complex and invasive disease that can cause myriad health problems in nearly all of the body’s major systems. This includes a number of conditions that can impact the eyes and a person’s ability to see. One of the most devastating is diabetic retinopathy, which can ultimately lead to loss of vision and even blindness.


November is Diabetes-Related Eye Disease Month, so let’s take a closer look at how this disease can impact vision and eye health and the importance of diabetic eye care.


Diabetic Retinopathy

As the name implies, diabetic retinopathy can occur in the retinas of an individual with diabetes. Due to the impact of diabetes, the blood vessels in the body that feed the eye and retina can be weakened, causing them to bulge or even leak – a condition known as nonproliferative diabetic retinopathy. If uncontrolled, the disease can progress further, developing into proliferative retinopathy. In these patients, the blood vessels that have been damaged close off entirely, causing the formation of new vessels on the surface of the retina, leading to further and more serious vision problems.

In early stages, the disease is often imperceptible, though symptoms may include reduced visual acuity at distance or close up. More advanced cases may lead to visual artifacts such as eye floaters or streaks in the vision that may or may not clear up. If left untreated, the disease can progress further, leading to secondary conditions such as diabetic macular edema – a swelling of the macula causing blurred vision that occurs in about half of cases – or neovascular glaucoma, which can block the routine drainage of fluid from the eye. In severe cases, it can even cause the retina to detach from the back the eye.


Other Diabetic Vision Issues

In addition to diabetic retinopathy, having diabetes can increase your risk for two other severe eye conditions  glaucoma and cataracts. We’ve discussed each of these conditions previously in the blog, as they can occur in any person, but studies show that diabetics have nearly double the risk of developing these conditions of a non-diabetic person. This makes it all the more critical for those with diabetes to schedule an annual diabetic eye care appointment to look for any early symptoms of these or other diseases and discuss steps you can take to maintain your eye and visual health.


Another potential complication of diabetes is blurred vision as a result of excessive blood sugar levels. If your blood sugar level gets too high, it can cause your eyes’ lenses to swell, which can impact how light travels through the eye and cause things to look blurry. Fortunately, this symptom is easily controlled by better managing blood sugar levels and often can be reversed within a few days or weeks. However, diabetic patients with blurry vision should be sure to see their eye doctor as soon as symptoms occur as blurry vision can also be symptomatic of the other, more severe diabetes-related conditions discussed.


Prevention And Early Detection

The best way to prevent diabetic retinopathy is controlling your blood sugar. It is important to know your Hemoglobin A1 level (HbA1c), which gives you information about your blood sugar control over the past several months. Commonly used guidelines from the American Association of Clinical Endocrinologists and the American Diabetes Association suggest an HbA1c goal range of 7 percent to 8 percent for most patients to prevent diabetic complications. The Diabetes Control and Complications Trial (DCCT) showed a strong exponential relationship between the risk of diabetic retinopathy and the mean HbA1c level, with each 10 percent decrease in the HbA1c (e.g., from 9 percent to 8.1 percent), showing a 39 percent decrease in the risk of progression of retinopathy.


The National Institute of Diabetes and Digestive and Kidney Diseases also suggests that individuals with diabetes have annual eye exams. For Type 1 diabetics, annual exams should begin within five years of being diagnosed; Type 2 diabetics should start annual exams immediately after diagnosis. The NIDDKD also suggests that women who are diabetic and pregnant should have an exam within the first trimester, and follow their doctor’s recommendations for follow-up exams through their child’s first birthday. Expectant mothers who were not previously diabetic, but who develop gestational diabetes are not typically believed to be at any increased risk, but should raise any concerns with their eye doctor during pregnancy.


The American Academy of Ophthalmology adds that for most diabetics, diabetic retinopathy in some form may be nearly unavoidable. The Wisconsin Epidemiologic Study of Diabetic Retinopathy (WESDR) followed both Type 1 and Type 2 diabetic patients over the course of 20 years, finding that 99 percent of patients with Type 1 diabetes and 60 percent of Type 2 diabetics had signs of at least some degree or retinopathy. Maintaining annual visits with your eye doctor can help monitor your overall eye health, however, and provide an opportunity for your physician to notice any problems early before the disease can progress.

Dry, irritated eyes can make everyday activities such as uncomfortable. Artificial tears and other treatments may deliver temporary relief but do not always provide a permanent solution to the underlying cause of chronic dry eye. For many patients, the problem begins with meibomian gland dysfunction (MGD), a common condition that affects tear film quality. At Ross Eye Institute at UBMD, we use advanced technology to treat the root cause of dry eye with OptiLight® IPL (Intense Pulsed Light) and OptiPLUS™ , helping patients achieve long-lasting comfort and healthier eyes. What Is Meibomian Gland Dysfunction (MGD)? The meibomian glands are tiny oil-producing glands located along the edges of your eyelids. These glands release oils that help prevent tears from evaporating too quickly. When the glands become blocked or stop functioning properly, tears evaporate faster, leading to dry eye symptoms such as: Burning or stinging eyes Redness Blurred vision Gritty or sandy sensation Watery eyes Eye fatigue Light sensitivity MGD is a leading cause of dry eye disease and frequently worsens over time without treatment. What Is OptiLight® IPL? OptiLight® is an FDA-approved Intense Pulsed Light (IPL) treatment specifically tailored to manage dry eye disease associated with meibomian gland dysfunction. During treatment, the skin around the eyes is exposed to controlled pulses of light. These gentle pulses help reduce inflammation, improve meibomian gland function, and decrease abnormal blood vessels that contribute to chronic dry eye. Many patients notice gradual improvement after a series of treatments, with benefits including: Reduced dry eye symptoms Improved tear stability Less eyelid inflammation Greater comfort during daily activities Boosted overall eye health The procedure is non-invasive, requires little or no downtime, and usually takes a short office visit. What Is OptiPLUS™? OptiPLUS™ is often used alongside OptiLight® to deliver a more comprehensive treatment for dry eye disease. Following IPL therapy, OptiPLUS™ gently clears blockages from the meibomian glands, allowing healthy oils to flow more freely into the tear film. This combination targets both inflammation and gland obstruction, two major contributors to evaporative dry eye. Through combining these advanced technologies, patients may experience more effective and longer-lasting relief than with traditional treatments alone. Who May Benefit from IPL Dry Eye Treatment? OptiLight® and OptiPLUS™ may be recommended for patients who: Have chronic dry eye symptoms Have been diagnosed with meibomian gland dysfunction Depend on artificial tears multiple times each day Experience eyelid inflammation or redness Have not found sufficient relief from conventional treatments Spend long hours using digital devices A comprehensive eye exam lets your eye care specialist determine if these treatments suit your individual needs. What to Expect During Treatment Your provider will first evaluate your eyes and eyelids to determine the severity of your dry eye disease and meibomian gland function. During an OptiLight® session, protective shields cover the eyes while pulses of light are delivered to the treatment area. Patients often describe the sensation as a mild snapping against the skin. If OptiPLUS™ is included in your treatment plan, your provider will then gently express the meibomian glands to remove blockages and restore healthy oil flow. Most treatment plans include a series of treatments scheduled several weeks apart to get the best possible results. Find Lasting Relief from Dry Eye Living with chronic dry eye does not have to be your new normal. Advanced therapies like OptiLight® IPL and OptiPLUS™ treat the underlying causes of evaporative dry eye rather than just masking symptoms.  At Ross Eye Institute at UBMD, our experienced eye care specialists extend personalized dry eye evaluations and advanced treatment options to help restore comfort, improve tear quality, and protect your long-term eye health. If dry, irritated eyes are affecting your quality of life, schedule an appointment to learn whether OptiLight® and OptiPLUS™ are right for you.

Red, itchy, irritated eyes can be frustrating and uncomfortable. Many people assume these symptoms are caused by allergies, but dry eye syndrome can produce similar signs. Understanding the difference between dry eye and eye allergies is important to find the right treatment and protect your long-term eye health. At Ross Eye Institute at UBMD, our specialists work hard to identify the source of their symptoms and develop specific treatment plans to improve comfort and vision. Understanding Dry Eye Dry eye occurs when the eyes don’t make sufficient tears or when they evaporate too quickly. Tears play a key part in keeping the surface of the eye lubricated, nourished, and protected. Several variables lead to dry eye syndrome, including: • Aging • Extended screen time • Certain medications • Hormonal changes • Environmental conditions such as wind or dry air • Preexisting health conditions Dry eye symptoms may include: • Burning or stinging sensations • Gritty or sandy feeling in the eyes • Blurred vision • Eye fatigue • Sensitivity to light • Excessive tearing as a response to irritation Symptoms often worsen after reading, computer use, or prolonged visual tasks, so many patients notice discomfort later in the day. Understanding Eye Allergies Allergic conjunctivitis is a reaction to environmental allergens in which the eyes become inflamed. Common triggers include pollen, dust mites, pet dander, mold, and seasonal allergens. When the eyes come into contact with an allergen, the immune system responds by sending histamines through the body that cause inflammation and irritation. Common symptoms of eye allergies include: • Intense itching • Redness • Watery eyes • Swollen eyelids • Burning sensations • Mucus discharge Unlike dry eye, allergy symptoms often occur alongside other allergy-related issues such as sneezing, nasal congestion, or a runny nose. Key Differences Between Dry Eye and Eye Allergies Although the symptoms can overlap, several important differences may help distinguish between the two conditions. Itching Is More Common with Allergies Itching is often the hallmark symptom of eye allergies. While dry eye may cause irritation or discomfort, significant itching is more likely to be associated with an allergic reaction. Dry Eye Often Causes a Gritty Feeling Many patients with dry eye describe feeling as though sand or a foreign object is trapped in their eyes. This experience is less common with allergies. Allergies Usually Produce More Tearing Eye allergies often trigger excessive watering as the body responds to allergens. Dry eye can also cause reflex tearing, yet the eyes still feel dry. Symptoms May Follow Seasonal Patterns If symptoms worsen during spring or fall allergy seasons, eye allergies may be the cause. Dry eye symptoms persist year-round and may worsen in dry environments or during lengthy screen use. When to Schedule an Eye Examination Dry eye and eye allergies can look very similar, so a professional eye examination is often the best way to determine the underlying cause. You should schedule an evaluation if you experience: • Persistent redness or irritation • Ongoing blurry vision • Eye discomfort that does not improve • Frequent tearing or dryness • Light sensitivity • Symptoms that impede daily activities An eye care professional can assess tear production, evaluate the ocular surface, and find signs of allergies or other eye conditions. Finding Relief for Your Symptoms Proper diagnosis is the primary pathway to effective treatment. Dry eye management may include artificial tears, prescription medications, habit modifications, or advanced therapies. Eye allergy treatment often focuses on avoiding triggers and using antihistamines or anti-inflammatory medications when appropriate. At Ross Eye Institute at UBMD, we provide comprehensive eye care services to help patients find relief from dry eye symptoms, eye allergies, and other vision concerns. If you are experiencing ongoing eye irritation, scheduling a thorough optical test can determine the source and restore your comfort and eye health.
