Selective Ocular Arteriography in Living Experimental Animals

The clinical application of ocular arteriography is presently limited to the occasional demonstration in cerebral arteriograms of vessels of the orbit and to a fine crescent in the posterior part of the orbit representing the choroidal circulation.^1,2 In 1951, Schurr² suggested the application of cerebral arteriography in the visualization of orbital structures for demonstration of vascular abnormalities and differential diagnosis of orbital and ocular neoplasms. Verified results from this method have been few,^3-5 emphasizing the inherent difficulty in obtaining satisfactory films of this area by this method, and the inherent dangers of the procedures itself. The importance of radiographic diagnosis and study is attested to by the various procedures which have been developed,^1,6-8 such as venography and pneumography of the orbital structures.

For these considerations it was felt that the technique of perfusion of the ocular arteries via the infraorbital artery in experimental animals previously described
