Longitudinal studies showed progressive increases in AF followed by reduced AF associated with losses of visual sensitivity, outer retinal layers, and cones.

The onset of symptoms occurs in adolescence, although in some cases manifestations occur in the first decade of life. Disease definition Stargardt disease, also known as Stargardt 1 STGD1is an autosomal recessive form of retinal dystrophy that is usually characterized by a progressive loss of central vision associated with irregular macular and perimacular yellow-white fundus flecks, and a so-called ”beaten bronze” atrophic central macular lesion.

Stargardt disease is a genetic illness. In 1 instance, 2 affected persons married and both of their children were affected. A dominant Stargardt’s macular dystrophy locus maps to chromosome 13q Lipofuscin accumulation, abnormal electrophysiology, and photoreceptor degeneration in mutant ELOVL4 transgenic mice: The patient’s father was heterozygous for the mutation.

Round, linear, or pisciform lesions are distributed in the posterior pole, sometimes with extension to the equator, and with macular involvement. Exclusion of chromosome 11q13 region as a genetic locus responsible for autosomal dominant Stargardt’s disease. Ueber familiare, progressive Degeneration in der Makulagegend des Auges. Median ages of onset and baseline examination were enfeermedad.

In addition, two autosomal dominant types of macular dystrophy exist that resemble STGD1: From linkage studies, Gerber et al.

Constant right exotropia was present and was tsargardt at near than distance with a small hyper component. They found that nonsense mutations truncating the ABCA4 protein consistently led to Stargardt disease, whereas all mutations they identified in the ABCA4 gene in fundus flavimaculatus were missense mutations affecting uncharged amino acids. Preventive measures for slowing down the progression of the disease include avoidance of overexposure to visible light with sunglasses and no intake of vitamin A stragardt.

If loss of visual acuity begins in the first 2 decades, the designation Stargardt disease is preferred; if it begins later in life and has a more progressive course, the term FFM is preferred Weleber, Spectrum of ABCR gene mutations in autosomal recessive macular dystrophies.

Acuity loss progressed with age and generally was worse in the older affected individuals. Regular ophthalmologic evaluations are recommended by ophthalmologists experienced in this disease. While the OMIM database is open to the public, users seeking information about a personal medical or genetic condition are urged to consult with a qualified physician for diagnosis and for answers to personal questions.
