XXXX and their carotid origin.

Most eye problems referred to vascular surgeons for workup of @entity66 are either transient ( @entity1939 fugax) or partial (retinal branch @entity432 ) @entity227 . @entity1 with more severe total infarcts of the retina (central retinal @entity432 ) or of the head of the optic nerve (" @entity1781 ") are seldom suspected of @entity66 and, in the latter case, are generally labeled idiopathic. An explanation for the difference in attitude towards these conditions is suggested. A prescribed carotid etiology for these various @entity6810 was explored in a study of 20 consecutive @entity1 who had @entity6810 . Special visualization of the neck, orbital, and retinal vasculature was obtained. Sixty percent had ipsilateral and 50% had contralateral @entity2998 . The ophthalmic artery and the posterior ciliary arteries showed intrinsic lesions each in 25% of cases. Our pilot study concludes that there is strong evidence that most of these @entity63 are related to @entity2998 , which is found in the majority of @entity1 . In a minority of them ischemic problems may be due to @entity3468 or to intrinsic disease of the ophthalmic artery. A more cohesive approach to the study and treatment of these different entities is supported by the suggestion of a common etiology for most of them. Close collaboration with ophthalmologists will be needed to improve the present management of these eye conditions.
