... of the cerebral venous blood outflow may lead to chronic cerebrospinal venous insufficiency (CCSVI). According to this theory, CCSVI would trigger iron deposition along the cerebral veins, which would in turn activate the complement and macrophage system leading to periventricular demyelination, the hallmark...

... Abstract Ab externo Schlemm's canal (SC) surgery (e.g., viscocanalostomy and canaloplasty) is a valuable alternative to glaucoma filtration surgery. It targets the abnormally high resistance to outflow in the trabecular meshwork (TM) and reestablishes the physiologic outflow system...

... Abstract In primary open-angle glaucoma, the site of greatest resistance to aqueous outflow is thought to be the trabecular meshwork (TM) and inner wall of Schlemm's canal. Augmentation of the conventional (trabecular) outflow pathway can facilitate physiologic outflow and subsequently lower...

Just after birth, two parallel blood flows run through the heart. Oxygen-deprived blood runs from the heart's right atrium though the right ventricle to enter...

Postoperatively, the ocular surface also plays an important role, as the conjunctiva interacts with aqueous humor and subconjunctival fibrosis may block aqueous outflow and cause surgical failure. As preoperative inflammation underlies postoperative fibrosis and therefore surgical outcome, a better knowledge...

But still, many future IOP-lowering options will be developed, including neuroprotective strategies aiming to directly prevent or significantly hinder neuronal cell damage. The goal...

This results in an initial secondary open-angle glaucoma stage that may be amenable to intraocular pressure (IOP)-lowering medications and modulation of the underlying ischemic process, often in combination with panretinal photocoagulation...
