What are the risks of high myopia?

People with high myopia are at greater risk of developing eye diseases, such as:

• Glaucoma.
• Cataracts.
• Retinal tears which may lead to a retinal detachment.
• Myopic maculopathy or myopic macular degeneration.

Can high myopia cause blindness?

Myopia, particularly high myopia, not only impacts your vision in the short term, but it can eventually lead to blindness. Studies across the world have shown that myopia can increase your risk of blindness through disorders like macular degeneration, retinal detachment, glaucoma, and cataracts.

What are the disadvantages of myopia?

Those who develop high myopia, defined as ≤ −5 dioptres (D) are at increased risk of cataract, open-angle glaucoma, myopic macular degeneration and retinal detachment (p. 5), all of which has a personal and economic cost.

Is myopic eye bad?

Usually, myopia is a minor nuisance that can be corrected with eyeglasses, contact lenses or surgery. But in rare cases, a progressive type called degenerative myopia develops that can be very serious and is a leading cause of legal blindness. Degenerative myopia affects only about 2\% of the population.

Is minus 5.25 eyesight bad?

If your number is between -0.25 and -2.00, you have mild nearsightedness. If your number is between -2.25 and -5.00, you have moderate nearsightedness. If your number is lower than -5.00, you have high nearsightedness.

What are the disadvantages of spectacles in high myopia?

However, in high myopia, spectacles have the disadvantage of reducing the retinal image size, inducing peripheral distortion and reducing the effective visual field (especially with lenticulated lenses). Contact lens correction is warranted where spectacle correction is problematic or normal visual development is threatened.

How does myopia affect glaucoma risk?

Glaucoma. A systematic review of the available evidence concluded that the risk of developing glaucoma was nearly 50\% higher (or one and a half times as high) in individuals with moderate to high myopia, compared to those with low myopia (odds ratios [OR] of 2.5 and 1.7 respectively).7 Cataract.

What is the prevalence of high myopia?

High myopia generally begins in early childhood, and continued growth of the eye often means that the corrective lens prescription required to allow proper focus may not stabilize until the early adult years. The prevalence of high myopia has been increasing over the last several decades. Because more people are developing high myopia,

What happens if myopia is less than 5 d?

A person who needs ≤ −5 D of correction has a visual acuity that is far worse than the threshold for blindness (–3/6 in the better eye). Even when appropriate refractive correction is provided, myopia continues to place an individual at an increased risk of sight-threatening diseases, including5,6: Glaucoma (open-angle)
