Vision Information: High Degree Myopia
Myopia, or short-sightedness is the inability to see distant objects clearly. It results from an irregular-shaped cornea.
Usually the condition stabilizes when the growth process is completed and can be corrected with eyeglasses or contact lenses. But high degree myopia is a progressive condition that can create problems because of its association with degenerative changes at the back of the eye.
In high degree myopia, near vision can deteriorate to a level where even objects very close to the face become hard to focus. And especially in the case of high myopia there is a slight danger of sight loss since the deformation of the eye creates stress on the retina which can become damaged or detached and also can provoke other changes.
Retinal detachment requires immediate treatment and its symptoms are light flashes, floaters (shadow-like shapes which appear singly or in clusters in the field of vision) or a "curtain" across the field of view. If you have any of these symptoms we strongly advise consulting an ophthalmologist for a comprehensive eye examination.
Around one in twenty-four patients with myopia will have high degree myopia. It can run in families and has a genetic relevance that should be discussed with your eye care professional.
Myopia is not curable but vision can be corrected in most cases. Corrective procedures for high myopia can vary and will depend on the severity of the condition, which is best diagnosed by an ophthalmologist.
