Age-related macular degeneration (macular degeneration) is the leading cause of irreversible severe vision loss. The incidence of degeneration increases with age.
Keratoconus is a degenerative, non-inflammatory disease of the cornea. It is a progressive disorder in which thinning of the cornea is observed centrally or paracentrically, resulting in a conical shape.
Glaucoma is a disease of the eye, which due to the blockage of the flow of aqueous fluid produced by the radial body, increases the intraocular pressure and destroys the ganglion cells of the retina. If the intraocular pressure remains high, untreated, then vision is at risk of damage.
One of the most common eye diseases is cataracts. The most common form is what we call “senile cataract”, which manifests itself in the context of the normal aging of the body and mainly affects the elderly.
Presbyopia is a problem that occurs in all people after the age of 40-45. In essence, this is not a disease but the normal aging process of the crystalline lens of the eye. The main symptom is reduced vision up close.
Hyperopia is the refractive error of the eye, in which a parallel beam entering the eye does not focus on the retina but meets it before it even forms a focus. Thus each point of an object is reflected in the retina as a circle of confusion and the object appears blurred. The hypermetropic eye can see clearly neither distant nor near objects.
In astigmatism, the refractive power of the eye is not the same in all meridians, so it is not possible to concentrate the rays entering the eye at one point. In most cases, astigmatism is due to a corneal disorder.
Myopia is the refractive error of the eye, in which light rays are not concentrated in the retina, as is normal, but somewhere in front of it. Its main symptom is the blurred perception of distant objects.
