Diabetic retinopathy is one of the eye conditions that affect people who are having diabetes or high blood sugar, from a longer time, says Dr. Kevin Niksarli. Over blood sugar levels can devastate the blood vessels which are situated at the backside of the eye, shuns the retina from getting the right amount of nutrients it requires to uphold proper vision.
The retina is a light thin nerve tissue that is present at the back of the eye. As light penetrate on the front of the eye, it converts the light into electrical form which travel from the optic nerve to fraction of the brain called as the visual cortex. Then the brain combines all the images received from both eyes to read them as a single and 3D image, says Kevin Niksarli. This allows us to see distance and depth images. Without retina, the eye can’t converse with the brain, and vision become impossible.
Diabetic retinopathy happens as diabetes harms the minute blood vessels of the retina. In its early stages, called non-proliferative retinopathy, the blood vessels pour fluid and distort the sight. In the advanced stage, called proliferative retinopathy, some thin new blood vessels cultivate near the retina and vitreous humor. If it is left uncured, these bloody vessels may bleed out, blur the vision or scar cracking the retina.
Anyone with diabetes type 1 or 2 is at danger of rising diabetic retinopathy. However, the diabetes type a person is having, how frequently their blood sugar varies, how well their sugars are controlled, and duration of diabetes all affect his or her dangers. The better the blood sugar levels are controlled, the lower your danger you are having.
Diabetic Retinopathy Symptoms: There are usually no early indications of diabetic retinopathy and vision may not be distressed until the situation is severe. However, the common signs of the diabetic retinopathy are loss of central visualization while driving or reading, inability to see the colors, and faintness of vision. Small floaters or spots may also points that blood vessel leaks and may clarify in sometime. However, as the bleeding frequently happens over once, it is essential to examine your eyes yearly, and treat immediately if you undergo any of these symptoms.
Diabetic Retinopathy Treatments: In most of the cases, a laser surgery can prevent from major vision loss related with diabetic retinopathy. A technique called as laser photocoagulation can be used to seal off or destroy the growing or leaky blood vessels of the retina. This laser technique is not painful; but may lower one’s night sight and capability to see colors.
In some people who are undergoing with diabetic retinopathy, the blood that leaks out from blood vessels within the retina might also leak in the vitreous humor, and as a result cause cloudy vision. For this to be treated a surgical technique called as vitrectomy can be utilized to take away the blood that is leaked in this area of the eye.
If diabetic retinopathy diagnosed in proper time, almost 90% of people can be saved from sightlessness. Learn about other eye care topics such as pink eye and macular dengeration.
