What does posterior scleral staphyloma mean?

Posterior staphyloma is a type of eye condition, typically caused by high myopia.

In cases of high myopia, especially with myopia exceeding 800 degrees, not only does the axial length of the eye elongate, but the posterior sclera also becomes relatively thin, allowing a bluish-purple hue to show through. If not effectively controlled, this may lead to continuous elongation of the ocular axis and gradual posterior expansion and bulging of the back wall of the eyeball, forming a concave deformation known as posterior staphyloma.

Once posterior staphyloma develops, prompt medical treatment at a hospital is necessary. Additionally, patients should avoid strenuous physical activities in daily life to prevent retinal detachment, which could result in vision loss or even blindness.
