Surgery Notes

Retinal detachment, as its name indicates, is the separation of light-sensitive membrane located at the back of the eye, ie the retina. If caught early are very likely to bring solution although in some cases you can not do anything to save the patient’s vision. Dr. Sergio Bonafonate, an expert in retinal and Vitria, eye surgeon and director of Medical Center Ophthalmology BONAFONT explains what this condition and can be done to put solution.

What is the Retina
The retina, as already indicated, is a sensitive membrane that covers the entire eyeball inside her. Its mission is to capture images of light entering the eye and transform them into nervous stimuli to the true vision is formed on the back wall of the brain, ie the visual cut.

Causes of Detachment
There are many causes that may be the driver of a detached retina, but in certain occasions the experts do not quite determine which is the reason. Retinal detachment occurs because a liquid that fills the eyeball area eventually collapse and cause the retina to break. This phenomenon can occur at any age, even at the time of birth. In most cases occur in people aged 60 years, although it is true that previous surgery such as cataract, may be inducing a retinal detachment.

Symptoms of Retinal Detachment
The person who has been detached retina in his field notes that appear like flies or visual floaters. Sometimes even perceive flashes of light in a zig zag, as if it were lightning. You may also be that the person perceived as if a dark curtain will fall and the visual field. Retinal detachment is not a phenomenon that occurs gradually so the symptoms appear abruptly.

Diagnostics
For diagnosis is simply to review the back of the eye and the inside of the eyeball. With that there will be enough to see if the retina has detached from the area. At one time it requires to perform an ultrasound but this happens rarely.

Treatments
If retinal detachment has occurred in a localized manner may be treated with laser, but when the retina detaches completely because of fluid build-up surgery is the only option. The evolution is correct forecast of 90-95%, and the patient retains a more or less good, if not complete. But there is 5% of patients who for various reasons end in blindness and the eye pressure rises or because they do not get re-apply the retina.

Can it be Prevented?
Retinal detachment can be prevented in cases that have a family history of pathology, when there are degenerative changes in the same area and when detected lesions reticular encourage detachment. If diagnosed early can prevent the release through laser treatment.
