If these findings are confirmed in larger studies, the researchers believe better advice can be given to patients with hereditary hemorrhagic telangiectasia
who are considering embolization for PAVMs.

Videolaryngostroboscopy reveals bilateral multiple vocal fold telangiectasias

HHT or Rendu-Osler-Weber disease is an autosomal dominant dysplasia characterized by widespread cutaneous, mucosal, and visceral telangiectasias
. These telangiectasias
, the hallmark of the disease, arise from the dilatation of postcapillary venules, which directly fuse with an arteriole, thus bypassing the capillary system.

From its initial description to the present day, there has been no consensus regarding the mechanism of perifoveal telangiectasia
. However, it is currently believed that the degeneration of Muller cells, which serve protective and supportive functions, is the primary pathology, and the damage to the retinal layers, atrophy, and vascular changes develop secondarily.
