Occlusion of posterior ciliary artery. IV. Electroretinographic studies.
The effects of posterior ciliary artery (PCA) occlusion have been studied in rhesus monkeys by Hayreh and Baines (I972 a, b, c), who reported the effects of occlusion of the medial PCA, lateral PCA, and all the PCAs on the choroidal circulation (Hayreh and Baines, I972a) and optic nerve head (Hayreh and Baines, I972C), and the productionof chorioretinal lesions (Hayreh and Baines, 1972b). Their...
متن کاملOcclusion of the posterior ciliary artery. II. Chorio-retinal lesions.
The clinical picture of central retinal artery occlusion is well-known. Little is known, however, about the clinical picture of occlusion of the posterior ciliary arteries (PCAs). We have, therefore, carried out experimental occlusion of the various PCAs individually or together in rhesus monkeys. The effects of such occlusions have been investigated in the choroid, pigment epithelium (PE), and...
متن کاملA Case of Incomplete Central Retinal Artery Occlusion Associated with Short Posterior Ciliary Artery Occlusion
To our knowledge, incomplete central retinal artery occlusion associated with short posterior ciliary artery occlusion is extremely rare. Herein, we describe a case of a 62-year-old man who was referred to our hospital with of transient blindness in his right eye. At initial examination, the patient's best-corrected visual acuity was 18/20 in the right eye. Fundus examination showed multiple so...
متن کاملPosterior Ciliary Artery Occlusion Caused by Hyaluronic Acid Injections Into the Forehead
Although cosmetic facial soft tissue fillers are generally safe and effective, improper injections can lead to devastating and irreversible consequences. We represent the first known case of posterior ciliary artery occlusion caused by hyaluronic acid. A 41-year-old female presented with right visual loss 7 hours after receiving cosmetic hyaluronic acid injections into her forehead. Examination...
متن کاملOcclusion of the posterior ciliary artery. 3. Effects on the optic nerve head.
The two or three posterior ciliary arteries (medial and lateral posterior ciliary arteries), which are the source of blood supply to the posterior choroid, are also the major souice of blood supply to the optic nerve head (Hayreh, i969, I970) and have a segmental distribution (Hayreh, I970, I97ib). The ciliary circulation is the only source of blood supply to the lamina cribrosa and prelaminar ...
