AMD (Age-related macular degeneration)

MD has become one of the most common causes of visual loss in people over 65 years worldwide. One of the most characteristic symptoms when the patient says he sees straight lines or curves there is a blind spot in the center of the visual field.

We differentiate two types: dry AMD and wet AMD;

Wet AMD is the more dangerous of the two, as it has a very rapid evolution can affect the retina irreversibly. It is very important to detect it early, because if detected early has a solution (with new antiangiogenic treatments and laser).
Dry AMD has a more slow and less dangerous than wet, but it is important to follow up with frequent visits to a retinal specialist ophthalmologist.

Diabetic Retinopathy

Diabetic retinopathy is the 1st cause of blindness in the western world. Diabetes alters the blood vessels of the retina and the whole organism. Although eye disorders may go unnoticed, are discovered in a patient ophthalmologic examination or when he dims the light or the completely lost, so recommend ophthalmological examination at least once a year.

We differentiate two types:
- Base diabetic retinopathy or background, central vision diminishes patient but retains lateral view. Can not read or recognize faces.
- Proliferative diabetic retinopathy, blood vessels close they tend to break and bleed.

The most important treatment is to use the laser to close or fotocoagular leaky blood vessels. This treatment does not need surgery and can be done in the office.
However, the laser can not be used in all patients. If the vitreous humor is full of blood, is a vitrectomy.

Vitreous detachment

With age, the vitreous tends to deteriorate losing water and decreasing its volume, and become smaller, tends to pull the retina to separate. The vitreous body is a transparent jelly, which is subject to various points on the retina and is made up mostly of protein.

The most characteristic symptoms are seen floaters and / or flashes of light, even as cobwebs.
The vitreous detachment does not involve any treatment at first, only the constant revisions by a retinal specialist ophthalmologist because it can lead to retinal detachment.

Retinal Detachment

It occurs when, for once, a tear or excessive traction, or part of the retina is detached from its usual place. The vision becomes defective and lose certain areas of the visual field.

Some patients describe it "as if it ran a curtain" in front of the eye.

There are conditions that may increase the possibility of retinal detachment:

  • The myopia or high myopia.
  • Weak areas in the peripheral retina.
  • Family history of retinal detachment.
  • Ocular trauma.
  • Previous ocular surgery complicated.

Treatment for retinal detachment depends on each case but always ends in an effective outpatient surgery.

Other diseases of the retina

There are other diseases that can affect different parts of the retina and the macula or optic nerve, all covered by our specialists.

  • Hypertensive Retinopathy
  • Retinopathy of toxemia of pregnancy.
