Does all high myopia lead to retinal detachment?

The risk of developing a retinal detachment is five or six times greater in people with high myopia (OR >20) compared to those with low myopia (OR <4). People with high myopia have longer eyes (axial elongation), which means that the retina is more stretched and therefore prone to peripheral retinal tears.

How common is retinal detachment with high myopia?

The yearly incidence of retinal detachment is approximately 0.015\% in eyes with up to -4.75 D of myopia, 0.07\% in eyes with -5.00 to -9.75 D, and 0.075\% in eyes with myopia greater than -10.00 D.

What level of myopia causes retinal detachment?

Patients with pathological myopia (ie, > −8 diopters) are at increased risk of retinal detachment due to axial elongation of the globe and peripheral retinal thinning.

Does high myopia lead to glaucoma?

High myopia is associated with an increased risk of pathological ocular complications and may lead to blinding disorders such as premature cataracts, glaucoma, retinal detachment, and macular degeneration[18].

Is high myopia the same as degenerative myopia?

If you’ve been diagnosed with pathological or degenerative myopia, you have very high myopia and your eye also shows degenerative changes affecting the back of the eye (the retina).

How common is high myopia?

Nearly 4 percent of adults in the United States have high myopia, defined as -6.0 D or worse in their right eye. That is equivalent to 9.6 million people. The prevalence of progressive high myopia is 0.33 percent.

Which is the most common complication of high myopia?

The most important complication of myopia is MMD, which is a common cause of visual impairment, particularly for high myopia. Characteristics of MMD are lacquer cracks, Fuchs spot, choroidal neovascularization (CNV), or chorioretinal atrophy.

What is consider high myopia?

Doctors generally define high myopia as nearsightedness of -6 diopters or higher, according to the American Association for Pediatric Ophthalmology & Strabismus. The Association also notes that high myopia often occurs in people with very long eyes, and typically appears during early childhood.

Why myopia is a risk factor for glaucoma?

As your myopia gets worse, retinal nerve fiber layers and macular thickness change too, putting you at risk of having glaucoma. Severe nearsightedness may also cause segmentation errors during macular imaging, making it difficult to accurately diagnose glaucoma.

How is myopia a risk factor for glaucoma?

The relation between myopia and open-angle glaucoma is not well understood. The underlying mechanism as to why myopia can lead to open-angle glaucoma is thought that the axial length increase leads to the tilting of the optic disc, causing damage to the axons in the lamina cribrosa.

What level of myopia is legally blind?

In order to be considered Legally Blind, your vision must be WORSE than 20/200 in your BEST eye while you are wearing your glasses or contacts.

What are some medical complications that can result from myopia?

Myopia can be corrected optically by glasses, contact lenses, or refractive surgery. Nevertheless, it has been associated with complications, such as myopic macular degeneration (MMD), retinal detachment (RD), cataract, and open angle glaucoma (OAG).

What happens if you have high myopia?

High Myopia. High myopia is associated with an increased risk of pathological ocular complications and may lead to blinding disorders such as premature cataracts, glaucoma, retinal detachment, and macular degeneration [18]. Thus, high myopia is a major cause of legal blindness in many developed countries [19].

Is high myopia a risk factor for glaucoma?

Many studies found that high myopia has been associated with POAG. It is possible that myopic individuals may be at increased risk for the development of glaucoma [8]. Epidemiologic evidence suggests that high myopia is a risk factor for the development and the progression of glaucomatous optic neuropathy [4].

What is the difference between high myopia and retinal detachment?

Retinal detachment. The risk of developing a retinal detachment is five or six times greater in people with high myopia (OR >20) compared to those with low myopia (OR <4).9People with high myopia have longer eyes (axial elongation), which means that the retina is more stretched and therefore prone to peripheral retinal tears.

What should ophthalmic workers do if a patient has high myopia?

Assess visual fields if possible. Ophthalmic workers should acknowledge high myopia as a significant cause of visual impairment and a risk factor for a number of sight-threatening conditions. Key messages High myopia is becoming more common
