Severe open angle glaucoma in hereditary hemorrhagic telangiectasia

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease. Conjunctival telangiectasias and retinal vascular malformations are known ocular manifestations. We report here the first case of open angle glaucoma in a patient with HHT caused by a nonsense mutation, C471X in the ACVRL1 gene.
