Diabetic
Retinopathy
What is Diabetic Retinopathy?
Diabetic
retinopathy is the most common diabetic eye disease and a leading cause
of blindness in American adults. It is caused by changes in the blood
vessels of the retina.
In some people with diabetic retinopathy, blood vessels may swell and
leak fluid. In other people, abnormal new blood vessels grow on the surface
of the retina.
The retina is the light-sensitive tissue at the back of the eye. A healthy
retina is necessary for good vision.
If you have diabetic retinopathy, at first you may not notice changes
to your vision. But over time, diabetic retinopathy can get worse and
cause vision loss. Diabetic retinopathy usually affects both eyes.
Does Diabetic Retinopathy have any symptoms?
Often there are no symptoms in the early stages of the disease, nor
is there any pain. Don't wait for symptoms. Be sure
to have a comprehensive dilated eye exam at least once a year.
Blurred
vision may occur when the macula—the part of the retina that provides
sharp central vision—swells from leaking fluid. This condition
is called macular edema.
If new blood vessels grow on the surface of the retina, they can bleed
into the eye and block vision.
How is Diabetic Retinopathy treated?
Careful dilated eye examination should be performed by your primary
eye care doctor on a regular basis at least once a year. If Diabetic
Retinopathy is detected, the Macula Center of North Carolina offers state-of-the–art
diagnostic testing.
Special testing for Retinal and Macular Disease
Digital Angiography - The Macular Center offers
world-class digital photographic and angiographic testing. In
these tests, special photographs are taken of the retina, sometimes
including a small dye injection in the arm. These images allow
precise diagnosis and treatment of retinal disease.
- High Definition
OCT - The Macula Center is proud to
be one of the first retinal practices to offer Zeiss Cirrus 3-D High
Definition scanning for macular disease. This safe, non-invasive
scan provides the latest in imaging quality for diagnosis and treatment.
Treatment for Diabetic Retinopathy
Depending on the severity of retinal involvement, many treatment options
are available.
- Laser Photo coagulation - The use of laser light
to coagulate leaking blood vessels and reduce swelling and bleeding
and swelling. Laser
treatment is performed in the office and is both safe and effective. The
Macula Center of North Carolina offers the latest in state-of the-art
Zeiss® laser technology.
- Drug Therapy - In certain
cases, DR can be treated by injectable drugs. The eye is pretreated
with anesthetics and antibiotics. This office procedure is safe and
effective.
- Surgery - Advanced cases of Diabetic Retinopathy
are treatable with modern hospital based surgery called vitrectomy. This
procedure, usually performed under local anesthesia, involves removing
the vitreous fluid to clear away hemorrhage or repair retinal detachment. Dr.
Laborde now offers the latest in small incision, sutureless
vitrectomy. During
his training, Dr. Laborde had the great honor of completing his retinal
fellowship under Dr. Steve Charles, perhaps the foremost pioneer in
modern retinal surgical technique.
