Retrobulbar blood flow was measured by colour Doppler imaging in the ophthalmic, central retinal and temporal posterior ciliary artery (TPCA) and nasal short posterior ciliary artery.

Moreover, the Pulsatile Index, peak systolic velocity (PSV) and end diastolic velocity (EDV) of posterior ciliary artery (PCA), central retinal artery (CRA) and ophthalmic artery (OA) were quantified ...

Posterior superior alveolar artery; Infraorbital art.: infraorbital artery; OA: ophthalmic artery; SPCA: short posterior ciliary artery; LPCA: long posterior ciliary artery; CRA: central retinal ...

CCA: common carotid artery; ICA: internal carotid artery; ECA: external carotid artery; PPA: pterygopalatine artery; MCA: middle cerebral artery; Infraorbital art.: infraorbital artery; OA: ophthalmic ...

An ophthalmologist conducted a visual examination which showed central retinal artery occlusion (CRAO), the blockage of a major artery in the retina that causes severe vision loss or blurriness.

These results indicate that photoreceptor ciliary disassembly is a key event triggering photoreceptor dysfunction and retinal damage in the pathological process of RD.

These results indicate that photoreceptor ciliary disassembly is a key event triggering photoreceptor dysfunction and retinal damage in the pathological process of RD (Figure 1).

Retinal artery occlusion is a blockage in a blood vessel that supplies your retina. It usually occurs suddenly and can cause vision loss without pain.

Mavlyanova conducted a study that included 90 patients with end-stage chronic renal failure based on color ultrasound dopplerography, which also was used to study the blood flow of the orbital artery, ...

The non-perfusion of ciliary vessels damage macular retinal ganglion cells, which are related to the prognosis of ischemic CRVO (17, 26). When ciliary vessels are blocked, aqueous humor accumulates ...

The short posterior ciliary arteries supply the anterior optic nerve, choroid, retinal pigment epithelium (RPE) and outer 130mm of the retina (to the OPL), while the long posterior ciliary arteries ...
