Metamorphopsia can be a symptom of a number of eye disorders involving the retina or macula. Some of these conditions include the following: Age-related macular degeneration; Epiretinal membrane and vitreomacular traction; Posterior vitreous detachment; Macular hole; Diagnosis
8.7% global prevalence in 2020 [2] Macular degeneration, also known as age-related macular degeneration ( AMD or ARMD ), is a medical condition which may result in blurred or no vision in the center of the visual field. [1] Early on there are often no symptoms. [1] Over time, however, some people experience a gradual worsening of vision that ...

Aberrations of the eye. The eye, like any other optical system, suffers from a number of specific optical aberrations. The optical quality of the eye is limited by optical aberrations, diffraction and scatter. [1] Correction of spherocylindrical refractive errors has been possible for nearly two centuries following Airy's development of methods ...
The FDA approved two biosimilars for Eylea (aflibercept), a drug used to treat age-related macular degeneration, diabetic retinopathy and other eye conditions. Biosimilars Yesafili and Opuviz...
Macular degeneration happens with age, when the macula, at the center of the retina — “the part of the eye that sees the world for us,” Dr. Vlad Diaconita, a retinal and vitreoretinal ...
Specialty. Ophthalmology. Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes. Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
Refractive error - sometimes called "ametropia" - is when the refractive power of an eye does not match the length of the eye, so the image is focused away from the central retina, instead of directly on it. [12] [13] Types of refractive error include myopia, hyperopia, presbyopia, and astigmatism.
AMD Alliance International is a non-profit coalition of the world’s leading vision, seniors and research organizations working to raise awareness of age-related macular degeneration, understanding of available options for prevention, early detection, treatment, rehabilitation and support services. It is the only international organization in ...
Forster-Fuchs' retinal spot. An optical coherence tomography (OCT) of the retina, showing a Fuchs spot. The Fuchs spot (also known as Förster-Fuchs' Spot [1]) is a degeneration of the macula in cases of high myopia.
