Fuchs spots are caused by regression of choroidal neovascularization. [3] Since it is a medical sign, treatment is given for the actual cause. Photothermal laser ablation, photodynamic therapy, anti-VEGF therapy, or a combination of these are the treatment options of choroidal neovascularization due to pathological myopia.
A subconjunctival hemorrhage appears as a bright red patch on the white of the eye and is commonly referred to as a burst blood vessel. In hyphema, blood pools in the anterior chamber, where the iris (the colored part of the eye) and the pupil are located. Hyphemas are graded based on the amount of blood covering the cornea.
In many cases, myopia will stabilize once the growth process has been completed, but in more severe chronic cases, loss of vision can occur. Degenerative myopia, also known as malignant, pathological, or progressive myopia, is characterized by posterior sclera elongation and thinning (at least 25.5 mm to 26.5 mm) and high refractive errors of ...
The prevalence of myopia has been reported as high as 70–90% in some Asian countries, 30–40% in Europe and the United States, and 10–20% in Africa. [127] Myopia is about twice as common in Jewish people than in people of non-Jewish ethnicity. [129] Myopia is less common in African people and associated diaspora. [126]
Patients at high risk for rhegmatogenous retinal detachment, such as those with myopia (nearsightedness), those who have had cataract surgery, those with a previous detachment in the other eye, and those with lattice degeneration or posterior vitreous detachment (PVD), should be educated on the symptoms and warning sings of retinal detachment ...
If the brain never learns to see objects in detail, then there is a high chance of one eye becoming dominant. The result is that the brain will block the impulses of the non-dominant eye. In contrast, the child with myopia can see objects close to the eye in detail and does learn at an early age to see objects in detail. [medical citation needed]
In myopia that is no longer progressing, the crescent may be asymptomatic except for its presence on ocular examination. However, in high-degree myopia, it may extend to the upper and lower borders, or form a complete ring around the optic disc and form a central scotoma. The myopic crescent is commonly seen in pathological axial myopia.
Spherical aberration exacerbates myopia in low light (night myopia). In brighter conditions, the pupil constricts, blocking the more peripheral rays and minimizing the effect of spherical aberration. As the pupil enlarges, more peripheral rays enter the eye and the focus shifts anteriorly, making the patient slightly more myopic in low-light ...
