The retina is the layer of sensitive tissue that is in the back of the eyeball. It is in the retina where the images that you pass through the lens of the eye are focused.
Retinal detachment is a disease in which the retina, which is the neural structure of the eye and allows the translation of light rays that enter the eye into images, is detached from the outer layers, resulting in poor vision.
There are different causes for retinal detachment, sometimes arising holes that occur directly in the retina, membranes that pull or fracture or by inflammation, which also produces a separation of the layers of the retina. Some of these can be spontaneous and some of them by direct trauma on the eye.
Another cause is the so-called "traction detachment" that usually occurs in patients with uncontrolled diabetes, have a history of retinal surgery or who suffer from chronic inflammation.
How can we detect it?
The patient will usually notice a shadow that does not move anywhere in their field of vision. Before detachment occurs you may see moving blackheads ("flies") or lights (spontaneous flashes of light). You will then see a shadow that may or may not completely cover the vision (depending on the time of evolution or the site in the eye where the detachment begins).
For detection, it is necessary to go to the doctor's office, where the pupil will dilate to determine the damage. Occasionally, some other type of examination may be needed, such as an ocular ultrasound.
Treatment is usually surgical and is considered an emergency.. There are different types of surgeries, depending on the condition of the retina. Only inflammatory retinal detachments are medically managed, ie without surgery.
A patient who is not diagnosed early can definitely lose vision.
