What is Tractional retinal detachment?
Retinal traction detachment (RTD) or tractional retinal detachment (TRD) is defined as the separation of the neurosensory retina from the retinal pigment epithelium (RPE) due to the traction caused by proliferative membranes present over the retinal surface or vitreous.
What are the causes of retinal detachment?
There are many causes of retinal detachment, but the most common causes are aging or an eye injury. There are 3 types of retinal detachment: rhegmatogenous, tractional, and exudative. Each type happens because of a different problem that causes your retina to move away from the back of your eye.
How does Tractional retinal detachment occur?
Tractional retinal detachment happens when scar tissue or other tissue grows on your retina and pulls it away from the layer underneath. It can lead to serious vision loss. This type is often found in people with diabetes who have severe diabetic retinopathy, or damage to blood vessels in the retina.
Does retinal detachment happen suddenly?
Retinal detachment often happens spontaneously, or suddenly. The risk factors include age, nearsightedness, history of eye surgeries or trauma, and family history of retinal detachments. Call your eye care provider or go to the emergency room right away if you think you have a detached retina.
Why is Tractional retinal detachment concave?
The detached retina takes a concave shape in contrast to the convex shape of rhegmatogenous retinal detachment (RRD). In contrast to RRD, which is caused by one or more retinal breaks, RTDs are caused by tractional forces, and there is no retinal break in the area of RTD.
Can symptoms of detached retina come and go?
Some people may brush off symptoms, reasoning that since they’re not in pain there isn’t a problem. But that isn’t the case. Leading up to the retinal detachment, many people notice that their peripheral vision gradually begins to go. This may happen over the course of days or weeks.
What does Rhegmatogenous mean?
[ rĕg′mə-tŏj′ə-nəs ] adj. Arising from a rupture or a fracture.
