Diabetic Eye Disease in Fresno, CA
What is Diabetic Retinopathy?
Diabetic retinopathy is the most common diabetic eye disease. Diabetic eye disease occurs when blood vessels in the retina change, becoming weak and abnormal. These new vessels swell and leak fluid or even close off completely.
Diabetic retinopathy generally affects both eyes and occurs in stages. Diabetic retinopathy is a progressive disease, and as it reaches its later stages it becomes difficult to reverse vision loss.
Stages of Diabetic Retinopathy
Diabetic retinopathy ranges from mild to severe. There are two forms of diabetic retinopathy:
Nonproliferative Diabetic Retinopathy (NPDR)
NPDR is the earliest stage of diabetic retinopathy. Damaged blood vessels in the retina leak fluid and small amounts of blood into the eye, causing small blind spots in vision.
Proliferative Diabetic Retinopathy (PDR)
PDR mainly occurs when many blood vessels in the retina close, preventing enough blood flow. In response to this, the retina begins to grow new, abnormal blood vessels. This is called neovascularization. These new blood vessels are not able to supply the retina with proper blood flow. The new vessels are also often accompanied by scar tissue, which increases the risk of retinal detachment.
What Causes Diabetic Retinopathy?
Uncontrolled diabetes can lead to problems such as diabetic retinopathy. It is very important for diabetics to maintain good blood sugar and blood pressure as well as having regular diabetic retinopathy screenings at Fogg, Maxwell, Lanier & Remington EyeCare in Fresno, California. Controlling blood sugar also helps prevent cataracts, as the risk of cataracts is higher for diabetics.
