- 5x the risk of early cataracts
- 14x the risk of glaucoma
- 22x the risk of retinal detachments (peripheral retina)
- 41x the risk of maculopathy (disease of central retina)
The effects of near-sightedness, or myopia, are not simply alleviated through glasses or contact lenses. With or without glasses or contact lenses, myopia typically progresses throughout the growth of the child and usually stabilizes after teenage years.
If myopia is not controlled the risk of advancement significant leading to not only to pathology but to functional lifestyle issues and safety.
Eye doctors often refer to nearsightedness less than -5 or -6 diopters as "common myopia." Nearsightedness of -6 diopters or more is commonly called "high myopia."
This distinction is important because high myopia increases a person's risk of developing other eye problems that can lead to permanent vision loss or blindness. These problems include tearing and detachment of the retina, clouding of the lens (cataract), and an eye disease called glaucoma that is usually related to increased pressure within the eye. The risk of these other eye problems increases with the severity of the nearsightedness. The term "pathological myopia" is used to describe cases in which high myopia leads to tissue damage within the eye.
