Myopia magna

The myopia magna, high myopia o pathological myopia it is an eye disease in which objects that are far away are perceived blurred. This is due to the eyeball is longer than usual, which causes the eye to focus in front of the retina and not over it.

We talk about myopia magna when the patient has 6 to 8 diopters and degenerative lesions are observed in the retina.

Myopia magna

The myopia magna, high myopia o pathological myopia it is an eye disease in which objects that are far away are perceived blurred. This is due to the eyeball is longer than usual, which causes the eye to focus in front of the retina and not over it.

We talk about myopia magna when the patient has 6 to 8 diopters and degenerative lesions are observed in the retina.

What is myopia magna?

La myopia magna, Also known as high myopia, manifests when a patient with this refractive error presents between 6 and 8 diopters. In myopic patients, the objects are focused in front of the retina and not on it, causing the far vision is blurred, while the nearby one remains in good condition.

This condition occurs due to a excessive elongation of the eyeball that gives rise to a anomalous stretching of all structures, including the retina. Its presence increases the possibility of suffering from other eye problems, such as retinal detachment, so frequent eye exams are very important to minimize risks and complications.

Symptoms of myopia magna

Patients with myopia magna are often myopic since childhood, presenting vision problems from the 5 years. Over time, the refractive error evolves to overcome the 6 diopters, stabilizing usually at the end of adolescence.

There are patients in whom myopia continues to advance with age, this condition is known as degenerative myopia and should be closely monitored by an ophthalmologist to avoid major complications.

Some of the symptoms of high myopia are:

  • Far blurred vision and lack of visual acuity.
  • Presistence of photopsies or flashes of light.
  • The patient can reach perceive small spots on the retina, known as flying flies or myodesopsies.

When the patient has more than 6 diopters, periodic ophthalmological control is required in order to minimize the risks associated with this condition.

Complications

Having myopia magna increases the risk of various conditions that can compromise visual health.

The main complications of this refractive error are:

  • Retinal detachment, patients with high myopia are more prone to suffer tears in the retina that can lead to a detachment of the same. This condition is an ophthalmological emergency that must be attended to immediately.
  • Choroidal neovascularization, formation of abnormal blood vessels under the retina.
  • Atrophy that ends up affecting the central area of ​​the retina, the macula, compromising the sharpness of the central vision nearby.
  • Early onset of Cataracts.
  • Increased risk of glaucoma.
  • Other complications like a macular hole, submacular hemorrhages o myopic macular degeneration.

Whether the myopia magna evolves into degenerative myopia or if the diopters stabilize, the ophthalmological reviews are essential to prevent the appearance of these complications.

Treatment of myopia magna

There is no cure for myopia magna, however to prevent this refractive error compromising the quality of life the patient must resort to the use of glasses or contact lenses.

La refractive surgery with phakic intraocular lenses it is an alternative to correct myopia in patients with high diopters that have not increased in recent years. This will allow dispense with the use of glasses by implanting a custom-made lens.

In addition, and depending on the complications associated with myopia magna, there are several additional treatments. It can be done laser photocoagulation to those patients with retinal tears y vitrectomy in patients with retinal detachment.

Those who suffer from choroidal neovascularization they will have to undergo intraocular medication injections to decrease the presence of fluid and macular hemorrhages.

An early diagnosis and continuous ophthalmological evaluation are the tools we have at our disposal to prevent this condition from generating complications that seriously compromise vision.
