Diabetic retinopathy is caused as a side effect of diabetes. The condition leads to rapid loss of vision. Common symptoms may include spots or strings floating in your vision, blurred or fluctuating vision, impaired color vision, dark or empty areas in your vision and subsequent vision loss. Diabetic retinopathy usually affects both eyes. Laser treatment uses the heat from a laser to seal or destroy abnormal, blood vessels in the retina. Focal photocoagulation treatment is used to seal leaking blood vessels in a specific area of the retina. Scatter laser treatment, on the other hand, is used to slow down the growth of abnormal blood vessels that may have developed all over the retina. The ophthalmologist will make a particular number of laser burns depending on the spread of the blood vessels over the retina. Treatment may cause mild loss of central vision, reduced night vision and a decreased ability to focus. Some people may lose peripheral vision. But the vision loss is negligent in comparison with the damage that may be caused by untreated retinopathy. Rare complications include bleeding in the eye, vitreous hemorrhage, traction retinal detachment and accidental burns. Laser photocoagulation is a painless procedure, you may feel a slight stinging sensation or see brief flashes of light during the laser procedure. The vision may be blurry and your eye may hurt a little for a day or two after the treatment. All the precautions must be followed, and follow-up appointments must be kept. You should wear sunglasses after the surgery to avoid bright sunlight.
