Symptoms and Detection
Many times, patients report no symptoms in the early stage of Diabetic Retinopathy. Patients experience following symptoms in the advance stage of this eye condition:
Eye floaters and spots
Development of a scotoma or shadow in your field of view
Blurry and/or distorted vision
Corneal abnormalities such as slow healing of wounds due to corneal abrasions
Near vision problems unrelated to presbyopia
The irregular growth of new blood vessels gives rise to serious complications such as retinal detachment, vitreous hemorrhage, glaucoma and blindness. Usually, this disease affects both eyes.
How is it treated?
Depending on what you need to see at work, you might need to wear reading glasses or remove glasses that correct for nearsightedness until the effects of the eye drops wear off
Huge strides have been made in the treatment of diabetic retinopathy. Treatments such as scatter photocoagulation, focal photocoagulation, and vitrectomy prevent blindness in most people. The sooner retinopathy is diagnosed, the more likely these treatments will be successful. The best results occur when sight is still normal.
In photocoagulation, the eye care professional makes tiny burns on the retina with a special laser. These burns seal the blood vessels and stop them from growing and leaking.
In scatter photocoagulation (also called panretinal photocoagulation), the eye care professional makes hundreds of burns in a polka-dot pattern on two or more occasions. Scatter photocoagulation reduces the risk of blindness from vitreous hemorrhage or detachment of the retina, but it only works before bleeding or detachment has progressed very far. This treatment is also used for some kinds of glaucoma
Side effects of scatter photocoagulation are usually minor. They include several days of blurred vision after each treatment and possible loss of side (peripheral) vision.
In focal photocoagulation, the eye care professional aims the laser precisely at leaking blood vessels in the macula. This procedure does not cure blurry vision caused by macular edema. But it does keep it from getting worse.
When the retina has already detached or a lot of blood has leaked into the eye, photocoagulation is no longer useful. The next option is vitrectomy, which is surgery to remove scar tissue and cloudy fluid from inside the eye. The earlier the operation occurs, the more likely it is to be successful. When the goal of the operation is to remove blood from the eye, it usually works. Reattaching a retina to the eye is much harder and works in only about half the cases.
