Symptoms of Diabetic Retinopathy
There are two forms of diabetic retinopathy:
1. Retinopathy Subclinical: In which affect the small retinal vessels. Some vessels get smaller and others rise and form pockets that block the flow of blood plasma leakage occurring and then blood. These bleeding and leakage of blood vessels can cause bumps on the retina or form deposits called exudates. Subclinical retinopathy is considered an early stage of diabetic retinopathy. The view is not affected seriously and usually remains stationary, no progress in 80% of diabetic patients.2. Retinopathy: is the continuation of the previous form, with the addition of new blood vessels grow on the surface of the retina or optic nerve. These new blood vessels are very fragile and can rupture and bleeding into the vitreous. If the effusion of blood is abundant, it stain the vitreous is transparent, interfering with the passage of light. The result will be loss of vision. Besides the scar tissue formed from the masses caused by the rupture of blood vessels in the vitreous, you can drag and stretch the retina causing detachment of the same in the back of the eye. Loss of vision and even blindness can result from this process.
When bleeding occurs in proliferative retinopathy, the patient has a complete loss of vision. Although no signs of pain, this severe form of diabetic retinopathy requires immediate medical attention.
