1. Giant cell arteritis: a multicenter observational study in Brazil
OBJECTIVE: To describe demographic features, disease manifestations and therapy in patients with giant cell arteritis from referral centers in Brazil. METHODS: A retrospective cohort study was performed on 45 giant cell arteritis patients from three university hospitals in Brazil. Diagnoses were based on the American College of Rheumatology classification cr

2. Retinal protective effects of topically administered agmatine on ischemic ocular injury caused by transient occlusion of the ophthalmic artery
Agmatine, an endogenous polyamine and putative neuromodulator, is known to have neuroprotective effects on various neurons in the central nervous system. We determined whether or not topically administered agmatine could reduce ischemic retinal injury. Transient ocular ischemia was achieved by intraluminal occlusion of the middle cerebral artery of ddY mice

3. Systematization, description and territory of the middle and rostral cerebral arteries in broad-snouted caimans (Caiman latirostris)
Background: Information on the arterial vascularization of the broad-snouted caimans’ brain (Caiman latirostris), a specie from the Brazilian fauna, is inexistent and the literature consulted yielded only one description about the development of embryonic circulation and post-birth cerebrovascular alterations in the brain of three caymans. The objective of

4. Intervalos de referência da dopplervelocimetria das artérias oftálmicas em gestantes de baixo risco / Reference values of Doppler velocimetry of the ophthalmic artery in low risk pregnancy
Objetivo: Construir intervalos de referência para os índices da Dopplervelocimetria (DPV) da artéria oftálmica (AOF) e da artéria central da retina (ACR) em gestantes de baixo risco. Avaliar a reprodutibilidade da DPV no leito orbital. Método: Estudo observacional, longitudinal, com acompanhamento de 63 gestantes de baixo risco. Foram aferidos: índice

5. Unusual visual loss after snakebite
Snakebites are endemic in some parts of Thailand, being associated with several complications. Ocular disturbances are uncommon, except in cases of corneal or conjunctival injury, when the eye is directly exposed to the snake venom. The present study presents a case of combined ophthalmic artery occlusion and transient central retinal artery occlusion with m

6. Dopplervelocimetria da Artéria Oftálmica em Gestantes Portadoras de Lúpus Eritematoso Sistêmico Sem Atividade de Doença Renal
Purpose: To analyze the patterns of dopplervelocimetry of the ophthalmic artery in pregnant and no-pregnant patients with systemic lupus erythematosus (SLE) without renal disorder flares, and to compare the Doppler indexes of normal pregnant women. Methods: an observational study was carried out through Doppler indexes evaluation of the ophthalmic artery of

7. Análise do fluxo sanguíneo da artéria oftálmica por ultrassonografia Doppler em recém-nascidos pré-termos de muito baixo peso
A prematuridade está associada com uma alta incidência de complicações no período neonatal sendo uma das mais importantes a retinopatia da prematuridade (ROP) e suas seqüelas: ambliopia, estrabismo, cegueira. Estudos indicam que alterações no fluxo sanguíneo retiniano estão envolvidas na patogênese da ROP causando um crescimento vascular anormal d

8. PRESSÃO ARTERIAL MÉDIA E O FLUXO SANGÜÍNEO DA ARTÉRIA OFTÁLMICA EXTERNA EM GATOS (Felis catus Linnaeus, 1758) / ARTERIAL PRESSURE AND BLOOD FLOW IN THE EXTERNAL OPHTHALMIC ARTERY IN CATS (Felis catus, Linnaeus, 1758)
A medicina veterinária vem se beneficiando dos avanços tecnológicos dos meios diagnósticos em medicina, e da facilitação da divulgação da ciência. Para que novas tecnologias sejam utilizadas são necessárias informações acerca dos padrões normais para cada tipo de exame, para que se possa utilizá-lo na rotina e destiná-lo adequadamente para ca

9. Regulation of ocular blood flow during increases of arterial blood pressure.
The blood flow in the uvea in cats and monkeys during acute increases of arterial blood pressure is well controlled by a sympathetic mechanism protecting the eye from overperfusion. Ocular macrocirculation (ophthalmic artery) and ocular microcirculation (iris) were examined in 22 healthy subjects during acute increases of arterial blood pressure induced by p

10. Influence of age, systemic blood pressure, smoking, and blood viscosity on orbital blood velocities.
The influence of multiple systemic factors upon the blood velocities obtained from the orbital circulations was investigated. The velocities obtained by colour Doppler imaging from the ophthalmic artery, central retinal artery, and vein from 95 ophthalmologically healthy volunteers were analyzed. The effects of age, systemic blood pressure, and smoking habit

11. Arterial supply to the optic nerve and the retina of the sheep.
The arterial supply of the optic nerve and the retina of four fetal and ten adult sheep was studied by various injection techniques and verified by histological examination in one neonatal lamb. The optic nerve was supplied by the rostral cerebral artery, including the rostral hypophysial artery, the internal ophthalmic artery and its chiasmatic rete, and re

12. Neuro-ophthalmic features of carotid cavernous fistulas and their treatment by endoarterial balloon embolisation.
The neuro-ophthalmic features of 11 traumatic carotid cavernous fistulas and their successful occlusion by endoarterial balloon embolisation is reported. Significant improvement in all neuro-ophthalmic signs and symptoms occurred following treatment, however, ocular motility deficits persisted in 7 patients. All 11 fistulas were occluded and the patency of t
