Retinal Detachment


View Video
Is the separation of the light-sensitive membrane , located in the back of the eye (retina ) of its supporting layers.


The retina is the clear tissue at the back of the eye that helps one to see the images focused on it by the cornea and lens.
• The most common type of retinal detachment is often due to a tear or hole in the retina through which fluid may leak from the eye. This causes separation of the retina from the underlying tissues , much like a bubble under a decorative role . This is almost always caused by a condition called posterior vitreous detachment. However, it can also be caused by trauma and severe myopia . A family history of retinal detachment also increases the risk .
• Another type of retinal detachment is called traction and is seen in people with uncontrolled diabetes , previous surgery of the retina or have chronic inflammation.
When presented with retinal detachment , bleeding from blood vessels in the area may cloud inside the eye , which is normally filled with vitreous humor. Central vision becomes severely affected if the macula , the part of the retina responsible for fine vision , becomes detached.


• Bright flashes of light , especially in peripheral vision
• Blurred vision
• Floaters in the eye


Tests are done to verify the response of the retina and the pupil and one's ability to see colors properly . These tests may include:
• electroretinography ( a record of the electrical signals produced on the retina when one sees things)
• Fluorescein angiography
• Measurement of intraocular pressure
• Ophthalmoscopy
• Refractive tests
• Retinal photography
• Color tests
• Visual acuity
• Slit lamp examination
• Ultrasound of the eye


Most patients with a retinal detachment will need surgery , either immediately or after a short period of time.
Surgery may not be necessary if you have no symptoms or have had the detachment for a while .
Some types of retinal detachment surgery can be performed in a doctor's office :
• lasers can be used to seal the tears or holes in the retina before there is a retinal detachment.
• If you have a small retinal detachment , your doctor may place a gas bubble in the eye . This is called pneumatic retinopexy and helps the retina float back into place . The hole is sealed with a laser.
The most severe retinal detachments may require surgery in an operating room. Such procedures include:
• Introflexión or scleral buckle to gently push the wall of the eye up against the retina .
• Vitrectomy to remove the gel or scar tissue pulling retinal detachments or used for larger tears .
The traction retinal detachments can be monitored for a while before surgery . If surgery is needed, is usually vitrectomy.


The prognosis after retinal detachment depends on the location and extent of the detachment and early treatment . If the macula was not damaged , the prognosis with treatment can be excellent.
Most retinal detachments can be repaired , but not all. You can not recover all of your vision after surgery.


A retinal detachment causes vision loss . Surgery to repair can help recover some or all vision.
When to Contact a Medical Professional
A retinal detachment is an urgent problem that requires medical attention within 24 hours of the first symptoms.


Wear goggles to prevent eye trauma and control your blood sugar carefully if you have diabetes. Visit your eye doctor at least once a year , especially if you have risk factors for occurrence of a retinal detachment.
