Nearsightedness, technically known as myopia, is a condition which causes difficulty focusing on objects at a distance, while near vision remains normal. Myopia is one of the most common vision problems worldwide and it is on the rise.
People with myopia are usually able to see well up close, but have difficulty seeing objects at a distance. Due to the fact that they may be straining or squinting to see into the distance, they may develop headaches, eye fatigue or eye strain.
Myopia is a refractive error caused by an irregular shaped cornea that affects the way light is focused on the retina. For clear vision, light should come to a focus point directly onto the retina. In myopia, the cornea is longer than usual, resulting in a focus point that falls in front of the retina, causing distant objects to appear blurry, while close objects can be seen normally.
Myopia typically has a genetic component as it often appears in multiple members of a family and it usually begins to show signs during childhood, often getting progressively worse until stabilizing around age 20.
There may also be environmental factors that contribute to myopia such as work that requires focusing on close objects for an extended period of time and spending too much time indoors.
Diagnosis of Myopia
Myopia is diagnosed by an eye examination with an qualified optometrist. During the exam the optometrist will determine the visual acuity of the eye to prescribe eye glasses or contact lenses. A prescription for myopia will be a negative number such as -1.75.
Treatment for Myopia
Myopia is typically treated with corrective eyeglasses or contact lenses and in certain cases refractive surgery such as LASIK or PRK is an option. Surgery is the most risky treatment as it requires permanently changing the shape of the cornea.
Other treatments involve implanting a lens that reshapes the cornea called a phakic intra-ocular lens or vision therapy. A treatment called Ortho-k, in which the patient wears corneal reshaping contact lenses at night to see without correction during the day can be another option.
Rapidly progressing myopia is more than just a hassle — today’s research shows that it will put your child at increased risk of developing serious eye diseases in late adulthood, such as glaucoma, cataracts, retinal detachment and macular degeneration.
Fortunately, Dr. Ralph Paternoster can help slow the progression of your child’s myopia with a customized myopia management program.
What is Myopia Management?
Myopia management is an evidence-based program that can halt or slow the progression of myopia in children.
There are several options and each myopia management program is customized for each child. Dr. Ralph Paternoster can help you decide which method is most suitable for your child depending on their age and myopia level.
