Severe Nearsightedness

If you have severe nearsightedness, over -10D, you might have myopic degeneration.  The biomechanical theory assumes that the retina, in a myopic eye, is stretched over a larger than normal area because the eye is longer in shape than is normal.

Loss of central vision can occur if abnormal vessels grow directly under the macular.   This is called choroidal neovascularization. Early diagnosis and treatment can minimize the amount of vision loss.  Patients with myopic degeneration have an increased risk of developing peripheral retinal tears and retinal detachment.   This is why it is important for those with severe nearsightedness to have a dilated eye examination.
