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 .
Adult-onset vitelliform macular dystrophy (AVMD) consists of lesions similar to BVMD on the retina. However, the cause is not as definitive as BVMD. The inability to diagnosis AVMD via genetic testing makes differentiating between AVMD and pattern dystrophy difficult.

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.
Usually, it is present at birth as a flat, reddish-purple, tense and edematous lesion. Although half of lesions are congenital, 58% of KHE develop during infancy, 32% between age 1 and 10 years (32%) and 10% after 11 years of age. Moreover, adult onset has been described too with mainly males being affected. Both sexes are affected equally in ...
Normal adult hemoglobin A molecule comprises two α and two β globin chains associated with a heme ring. Mutation at the 6th position of the beta chain is the cause of sickle cell disease. [ 10 ] Due to sickle cell disease, vascular occlusion may occur in the conjunctiva, iris, retina, or choroid.
Gottron's sign is a pathognomonic cutaneous manifestation associated with dermatomyositis (DM), which is an inflammatory disorder affecting the skin and muscles. [1] The primary lesion of dermatomyositis appears as a violaceous, macular erythema with a symmetric distribution, which may progress and become poikilodermatous (atrophic with telangiectasia and pigmentary changes) and indurated (as ...
