It is categorized as "macular perifoveal telangiectasia", a neurodegenerative metabolic disorder, correlated with diabetes and coronary artery disease. It generally affects both eyes and usually affects both sexes equally. Type 3 is an extremely rare, poorly understood neurological disease of the retina.
Dilated blood vessels can also develop on the legs, although when they occur on the legs, they often have underlying venous reflux or "hidden varicose veins" (see Venous hypertension section below). When found on the legs, they are found specifically on the upper thigh, below the knee joint and around the ankles.
Angiomas and numerous abnormal, small, dilated telangiectatic vessels with thickened, sclerotic and calcified walls have been found in those brain areas which also show calcifications. [ 1 ] [ 2 ] By analogy to Coats disease , the exudative retinopathy is thought to result from breakdown of the blood-retinal barrier at the level of the vascular ...
Prominent blood vessels (telangiectasia) over the white of the eyes usually occur by the age of 5–8 years, but sometimes appear later or not at all. [7] The absence of telangiectasia does not exclude the diagnosis of A–T. Potentially a cosmetic problem, the ocular telangiectasia do not bleed or itch, though they are sometimes misdiagnosed ...
MVD, which is frequently fatal and is related to the much better-known Ebola virus, is sometimes known as "bleeding eye disease" because it damages people's blood vessels, causing them to bleed ...
Additional cases have been reported in individuals with leukemia [11] or myelofibrosis, [12] [13] multiple myeloma, [14] and myeloproliferative diseases (including Polycythemia Rubra Vera). [15] Rare instances of urticaria pigmentosa and TMEP coexisting have also been reported. [16] [17]
Rarely, only one eye is affected. In the acute stage, lasting a few weeks, the affected eye demonstrates an oedematous appearance of the nerve fiber layer, especially in the arcuate bundles and enlarged or telangiectatic and tortuous peripapillary vessels (microangiopathy).
Lesions lips, patient with hemorrhagic hereditary telangiectasia. Hereditary hemorrhagic telangiectasia (HHT), also known as Osler–Weber–Rendu disease and Osler–Weber–Rendu syndrome, is a rare autosomal dominant genetic disorder that leads to abnormal blood vessel formation in the skin, mucous membranes, and often in organs such as the lungs, liver, and brain.
