Vitelliform macular dystrophy is an irregular autosomal dominant eye disorder which can cause progressive vision loss. [1] This disorder affects the retina , specifically cells in a small area near the center of the retina called the macula .
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 ...
Macular dystrophy may refer to any of these eye diseases: Macular corneal dystrophy, a rare pathological condition; Macular degeneration, or age-related macular degeneration; Vitelliform macular dystrophy, an irregular autosomal dominant eye disorder
In 1909 he described 7 patients with a recessively inherited macular dystrophy, now known as Stargardt's disease, being described as a progressive and severe reduction of central vision, which develops in the first and second decade of life. [23] [2]
Diabetic Macular Edema (DME): is an eye disease specifically related to diabetes, occurring due to fluid build-up in the retina as a result of sustained high blood glucose levels. It can result in blurred vision and vision loss. [5] Eye floaters and spots: where visible cloud-like images appear to "float" in an individual's field of vision. [6]
Occult macular dystrophy (OMD) is a rare inherited degradation of the retina, characterized by progressive loss of function in the most sensitive part of the central retina , the location of the highest concentration of light-sensitive cells (photoreceptors) but presenting no visible abnormality.
A mutation in the BEST1 gene leads to a loss of channel function and eventually retinal degeneration. [10] Although BVMD is an autosomal dominant form of macular dystrophy, expressivity varies within and between affected families although the overwhelming majority of affected families come from northern European descent.
The prevalence of Functional visual loss neuro-ophthalmology clinics is said to be 5-12%, and general ophthalmology clinics 1-5%. [2] [3] It is said that the total prevalence may be much more higher because patients may also consult their general practitioners, internal medicine physicians, psychiatrists or neurologists.
