Diabetic Retinopathy is a common complication for people living with diabetes. This condition occurs when high blood sugar levels damage the blood vessels in the retina, the light-sensitive tissue at the back of the eye. Over time, these damaged blood vessels may leak or become blocked, leading to vision problems. In the early stages, diabetic retinopathy might not cause noticeable symptoms, but as it progresses, it can cause blurred or distorted vision, dark spots, and even vision loss.
Diabetic retinopathy is an eye condition caused by damage to the small blood vessels in the retina resulting from diabetes. Over time, elevated blood sugar levels can weaken these blood vessels, causing them to leak fluid or blood and potentially affecting vision.
Diabetic retinopathy can develop in people with either type 1 or type 2 diabetes. In its early stages, it may cause no noticeable symptoms, making regular dilated retinal examinations especially important.
This earlier stage occurs when damaged retinal blood vessels begin to leak or become blocked. Changes may include small hemorrhages, swelling, and reduced blood flow to the retina.
In more advanced cases, the retina may develop abnormal new blood vessels. These vessels are fragile and can bleed into the vitreous, potentially causing significant vision loss. Scar tissue may also form and lead to retinal detachment.
Diabetic macular edema occurs when fluid accumulates in the macula, the part of the retina responsible for sharp central vision. It can occur at different stages of diabetic retinopathy.
A comprehensive dilated retinal examination helps identify signs of diabetic retinopathy. Additional diagnostic testing may include optical coherence tomography (OCT), retinal photography, or fluorescein angiography.
Treatment depends on the severity of the condition and may include monitoring, intravitreal injections, laser treatment, or vitreoretinal surgery.
Managing blood sugar, blood pressure, and cholesterol is also important in reducing the risk of disease progression.
