Retinal Tears and Detachment
The retina is the lining of the inside of the eye. It sends messages to the brain so you can see.When the retina pulls away from the inside of the eye,tears,holes ordetachment can occur.
Signs of Retinal Tears and Detachment Retinal tears or detachment is painless. Signs include:
Sudden increase in floating spots in your vision
Sudden flashes of light in one or both eyes
A shadow or curtain over part of your vision
Sudden blurry vision
If you have any signs, see a doctor called an ophthalmologist right away. Retinal detachment is a medical emergency. If not reattached quickly, permanent vision loss can occur in the affected eye. Prompt medical care and treatment can save your vision. Your doctor will check your eye to find what is causing your signs. If a retinal tear, hole or detachment is found, surgery is done. If a tear or hole is treated before detachment occurs, you will likely retain most of your
Treatment for small holes or tears Small holes or tears are treated with a laser beam or a freeze treatment called cryopexy. These treatments are done in your doctors office.
A laser beam may be used to make burns around the retinal tear or hole. These burns cause scarring to secure the retina in place.
In cryopexy, intense cold is used to freeze the retina around the tear.
This freezes the area and causes a scar to develop. The scarring secures the retina to the eye wall. Treatment for retinal detachment. There are three types of surgeries used to treat retinal detachment. You may need to have this done in a hospital.
Scleral buckling a tiny band is attached to the outside of the back of the eye to gently push the wall of the eye against the detached retina.
Vitrectomy a tiny incision is made in the eye. Gas or silicon oil is injected to push the retina against the wall of the eye.
Pneumatic retinopexy A bubble of expandable gas is injected.
Over several days, the gas bubble expands, eventually causing the retina to reattach itself to the wall of the eye. With all of these surgeries, either laser beam or cryopexy is used to secure the retina back in place. It may take several months following surgery to know how well your vision will improve. Results are best when treatment occurs before retinal detachment.
Diabetic retinopathy is an eye problem that can cause blindness. It occurs when high blood sugar damages small blood vessels in the back of the eye, called the retina. All people with diabetes are at risk for this problem. There are things you can do to reduce your risk and prevent or slow vision loss.
Diabetic retinopathy can affect both eyes. You may not have any signs at first. As it worsens, blood vessels weaken and leak blood and fluid. As new blood vessels grow they also leak causing blocks in your vision.
Signs of Diabetic Retinopathy
Floating spots in your vision
Blocked or hazy vision
To help reduce your risk of vision loss:
Keep your blood sugar levels well controlled. This is one of the best ways to protect your vision. Work with your doctor, nurse and dietitian.
Keep your blood pressure and blood cholesterol levels normal. You may need to take medicine.
Have an eye exam each year by an eye specialist that includes eye dilation. An eye exam can detect early changes before you have any signs.
Call your doctor if you have any changes in your vision.
There is no cure for diabetic retinopathy, but laser treatment or surgery may be done to prevent or slow vision loss
