Eye Red Streak and Diabetes

Posted on February 10, 2021 | No Comments on Eye Red Streak and Diabetes

Unmanaged diabetes can make patient susceptible to diabetic complications such as Diabetic retinopathy, a diabetic eye disease in which blood vessels in the retina swell and leak fluid or even close off completely. In some cases, abnormal new blood vessels grow on the surface of the retina. This often accounts for the symptom, in which a patient sees red streak in his vision.

Patients with diabetic retinopathy would not notice changes in their vision in the disease’s early stages. They would initially see red streaks in their eyes. But as it progresses, it can lead to serious vision loss which cannot be reversed. The red streaks in the eye can be attributed to Microaneurysms or small bulges in blood vessels of the retina that often leak fluid. This causes the vessels to enlarge that looks life streaks. It can also be caused by Retinal haemorrhages or tiny spots of blood that leak into the retina.

Both are symptoms of Nonproliferative diabetic retinopathy (NPDR) which is the earliest stage of diabetic retinopathy. Most diabetics have mild NPDR, which usually does not affect their vision. However, if their vision is affected, it is the result of macular edema and macular ischemia. The former pertains to the swelling or thickening of the macula caused by fluid leaking from the retina’s blood vessels which latter pertains to when small blood vessels of the eyes closed. The macular damage causes blurring and vision loss.
