Retrobulbar blood flow in rat eyes during acute elevation of intraocular pressure.

Exp Eye Res 2021 06 28;207:108606. Epub 2021 Apr 28.

F.L. Lizzi Center for Biomedical Engineering, Riverside Research, New York, NY, USA.

Most studies of the effect of acute elevation of intraocular pressure (IOP) on ocular blood-flow have utilized optical coherence tomography (OCT) to characterize retinal and choroidal flow and vascular density. This study investigates the effect of acute IOP elevation on blood flow velocity in the retrobulbar arteries and veins supplying and draining the eye, which, unlike the retinal and choroidal vasculature, are not directly compressed as IOP is increased. By cannulation of the anterior chamber of 20 Sprague-Dawley rats, we increased IOP in 10 mmHg steps from 10 to 60 mmHg and returned to 10 mmHg. Read More

Cavernous sinus embolisation prior to removal of penetrating foreign body in a 6-year-old child.

BMJ Case Rep 2020 Dec 13;13(12). Epub 2020 Dec 13.

Department of Ophthalmology, Children's Hospital at Westmead, Westmead, New South Wales, Australia.

Transorbital penetrating foreign bodies are extremely rare in children and may penetrate the cavernous sinus or the underlying internal carotid artery. Parent vessel sacrifice and temporary balloon occlusion are feasible options for managing arterial injury during removal of the foreign body. Even in the absence of arterial injury, the ophthalmologist may encounter significant bleeding from the cavernous sinus deep in their operative field that is difficult to control. Read More

The Functional Anatomy of the Ophthalmic Angiosome and Its Implications in Blindness as a Complication of Cosmetic Facial Filler Procedures.

Plast Reconstr Surg 2020 10;146(4):745

From the Taylor Lab, Department of Anatomy and Neuroscience, and the Department of Surgery, University of Melbourne; the Plastic and Reconstructive Surgery Unit, The Royal Melbourne Hospital; and the Professorial Plastic Surgery Unit, Epworth Freemasons Hospital.
