Patients with over six diopters of nearsightedness have High Myopia. Usually, this is caused by having an eye that is longer than normal (26 mm and higher). It occurs in about 2% of the population. People with High Myopia usually can see very well with the help of Glasses or Contact Lenses. Some people with High Myopia are effectively treated with Refractive Surgery. High Myopia is believed to be hereditary – but the exact mode of inheritance is poorly understood. There may be an environmental stimulation for High Myopia in people who use their eyes excessively for near tasks such as reading and under use their eyes for distance sight such as when one is outdoors. People with High Myopia are at increased risk for developing holes or tears in their retinas that can lead to retinal detachments and loss of visual acuity. When a break or tear occurs, a person may see flashes of light and/or new floaters (spots in his or her vision). When the retina detaches from the back of the eye, a curtain may come across the field of vision and eventually cross the Macula and cause a person to lose the ability to read. People with High Myopia are also at greater risk of developing degeneration of the macula where the ability to distinguish fine print is lost. People with High Myopia should check the vision daily in each eye by covering their eyes one at a time and noticing if their vision appears to be normal. If they see poorly or notice new Floaters, Distortion, or a Curtain coming across their field of vision they should see an Ophthalmologist of other Eye Care Professional promptly to have the best chance of preserving their good vision.
