Ophthalmic Artery and Superior Ophthalmic Vein Blood Flow Dynamics in Glaucoma Investigated by Phase Contrast Magnetic Resonance Imaging.

Precis: Ophthalmic artery (OA) and superior ophthalmic vein (SOV) blood flow were quantified by phase contrast magnetic resonance imaging (PC MRI) and seemed lower in glaucoma. Venous flow dynamics was different in glaucoma patients with a significantly decreased pulsatility.

Introduction: Studies using color Doppler imaging and optical coherence tomography flowmetry strongly suggested that vascular changes are involved in the pathophysiology of glaucoma, but the venous outflow has been little studied beyond the episcleral veins.

[Characteristics and management of Uveitis-Glaucoma-Hyphema syndrome].

Introduction: Uveitis-Glaucoma-Hyphema syndrome (UGH) is caused by mechanical chafing of anterior segment structures by an intraocular lens, especially an anterior chamber lens. The objective of this study was to characterise the clinical course and risk factors of UGH syndrome at a time when posterior chamber implantation is the gold standard.

Patients And Methods: This was a retrospective study of 30 cases of UGH syndrome managed between January 2014 and September 2018.
