The onset of symptoms and the severity of vision loss vary widely. The adult-onset form begins later, usually in middle age, and tends to cause relatively mild vision loss. The two forms of vitelliform macular dystrophy each have characteristic changes in the macula that can be detected during an eye examination.
Age-Related Macular Degeneration is a degenerative maculopathy associated with progressive sight loss. It is characterised by changes in pigmentation in the Retinal Pigment Epithelium, the appearance of drusen on the retina of the eye and choroidal neovascularization. AMD has two forms; 'dry' or atrophic/non-exudative AMD, and 'wet' or ...
Generally, diseases outlined within the ICD-10 codes H30-H36 within Chapter VII: Diseases of the eye, adnexa should be included in this category. Wikimedia Commons has media related to Disorders of choroid and retina .
Dietary antioxidant vitamins, minerals, and carotenoids do not appear to affect the onset; [5] however, dietary supplements may slow the progression in those who already have the disease. [ 5 ] Age-related macular degeneration is a main cause of central blindness among the working-aged population worldwide. [ 6 ]

Fundus of geographic atrophy. Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision over time.
Stargardt disease is the most common inherited single-gene retinal disease. [1] In terms of the first description of the disease, [2] it follows an autosomal recessive inheritance pattern, which has been later linked to bi-allelic ABCA4 gene variants (STGD1).
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.
