According to the World Health Organization (WHO, 2014), diabetic retinopathy is one of the leading causes of blindness. When blood vessels in your eye leak or swell, you may notice a change in your vision.
Diabetic retinopathy can impair your vision in two ways:
Firstly, the macula is the part of your eye that is responsible for fine detail in your vision. When fluid leaks into the macula it causes swelling. If this happens, it is called macular edema. To help treat your condition, Dr. Drouilhet may recommend injections or laser (or a combination of the two). The videos below give you a brief explanation of what can be expected for either or both treatments.
The second way diabetes can impair your vision is by the leaking of retinal blood vessels into the vitreous. This condition is called Nonproliferative Diabetic Retinopathy (NPDR). NPDR can be treated with focal or grid laser at our office. Your eyes are dilated prior to the laser and most patients have minimal discomfort.
When retinal blood vessels are obstructed and begin to grow and reproduce, this is called neovascularization. If neovacularization occurs, this condition is called Proliferative Diabetic Retinopathy(PDR). Neovascularization occurs because your retina is trying to compensate for its blockage. One complication with neovascularization is vitreous hemorrhage. Vitreous hemorrhage is when blood leaks into the vitreous of your eye. The second complication that can occur is retinal traction detachment. This is when scar tissue on the retina pulls the retina off the back wall of the eye. Whatever the case may be, Dr. Drouilhet may recommend either laser or vitrectomy surgery. The videos below show how these two procedures are performed.
