Understanding diabetes is the first step in protecting your vision and overall health.
Diabetes is a chronic disease in which the hormone insulin is either underproduced or unable to regulate blood sugar effectively. When diabetes is not controlled, blood sugar levels rise and lead to hyperglycemia, or high blood sugar.
Hyperglycemia damages many systems in the body, including blood vessels and nerves. Over time this damage can affect the eyes, heart, kidneys, and other organs.
Diabetic eye disease is a group of conditions caused or worsened by diabetes. Some problems develop without early warning signs, making regular eye exams essential.
Conditions linked to diabetes include diabetic retinopathy, diabetic macular edema, glaucoma, and cataracts. Diabetes increases the risk of cataracts fourfold and can also cause dryness and reduced corneal sensation.
Diabetic retinopathy occurs when high blood sugar damages the tiny blood vessels in the retina. Leaking or abnormal vessel growth can bleed, scar, and distort vision, and advanced stages may lead to blindness.
The early stages often have no symptoms, which is why frequent diabetic eye exams are vital. As the condition progresses, you may notice:
Scar tissue from damaged vessels can pull the retina away from the underlying tissue, causing a retinal detachment. Sudden floaters or flashes of light can signal this emergency, and quick treatment is critical to save vision.
Diabetic macular edema develops when fluid collects in the macula, the part of the retina responsible for clear central vision. About half of patients with diabetic retinopathy may develop this complication, which leads to vision loss.
Early detection offers the best chance to reduce vision loss. Laser therapy, injection treatments, or vitrectomy surgery can limit damage from proliferative diabetic retinopathy or diabetic macular edema, though lost vision is often not fully restored.
Active steps can greatly lower the risk of eye problems related to diabetes.
Because diabetic eye disease may not cause symptoms in its early stages, regular comprehensive eye exams allow for early diagnosis and timely treatment. Some health insurance plans now track eye exam frequency as part of overall diabetes care.
Following your medical plan for diet, exercise, and medication helps keep blood sugar in check and slows eye disease progression. Routine screenings for blood pressure, cholesterol, and kidney function also support long-term eye health.
