News » Retinal detachment: causes, symptoms and prevention
The retinal detachment is an eye disease characterized by the lifting of the neuroretin to which is assigned to transmit the visual signals, via photoreceptors and nerve cells.
Under ordinary conditions the retina adheres perfectly to the inner surface of the eye.
Due to a rupture or a hole, it can detach from the texture to which it adheres and crumple. In this situation the retina is no longer able to transmit adequate signals of the image to the brain and, consequently, the vision becomes blurred and reduced.
Determining causes. .
There can be several causes for retinal detachment.
The disease can affect people of average age who have a medium to high myopia, although it is a fairly rare phenomenon (1 in 10,000), or individuals with peripheral retinal degeneration in the eyes. In other cases, it is a consequence of an injury or ocular vitroretinic traction in an advancing diabetic retinopathy. Retinal tears and consequent detachment may also take place, in some rare case, in young individuals.
There are several symptoms that occur in the presence of retinal detachment.
Firstly, this condition is never painful. The most common symptom is the vision of a kind of "tent" in the visual field. Can be perceived flashes of light or flashes of light or dark spots or lines in the visual field, the so-called "floaters" typical of floaters.
In any case, immediate action can minimize damage to the eye, then in the presence of a sharp decline in vision, you should immediately carry out the necessary checks going at an emergency room or by an ophthalmologist.
How to diagnose it.
In some cases, when the retinal detachment is diagnosed early, simply around the retinal degeneration treatment called argon laser photocoagulation.
Other times, however, a surgery considered necessary that runs usually under general anesthesia. In most cases it is sufficient a single operation.
After surgery you do not feel pain, but the eye can be inflamed and may need to stay in hospital for a few days.
Undergo the operation is of primary importance in all cases in which the risk is to lose totally or partially the view and, as regards the timing, the greater the duration of retinal detachment, the lower the possibility of visual recovery.
To do prevention first of all it is necessary to ensure that it can not exist a genetic predisposition to retinal detachment.
In the case where it has already undergone detachment in one eye it will require greater attention regarding the other\'s health, and be subject to more frequent eye checks.
Finally, if the eye doctor should find the alterations in the peripheral retina, retinal detachment can be prevented by carrying out a treatment with laser photocoagulation.
For some individuals at risk, such as those with high myopia or floaters, eye doctors recommend avoiding those activities involving sudden movements of the head and eye.
