An implant for pressure relief in glaucoma cases consists of a tube (5) within the eye socket and an inflatable section (8), connected to one end of the tube, that can be attached to the back surface of the eye ball. When uninflated, this section has a bulbous form with a surface ...
Glaucoma refers to a group of disorders that lead to damage to the optic nerve, the nerve that carries visual information from the eye to the brain. Damage to the optic nerve causes , which may progress to . Most people with glaucoma have increased fluid pressure in the eye, a condition ...
1. A method for controlling fluid flow to and from an eye during ophthalmic surgery, said method composing the steps of: introducing irrigation fluid into an eye; determining initial irrigation fluid pressure; adjusting irrigation fluid flow based on the determined initial irrigation fluid pressure; ...
Glaucomais a disease that damages your eye’s optic nerve. It usually happens when fluidbuilds up in the front part of your eye. That extra fluid increases thepressure in your eye, damaging the optic nerve. Thereare two major types of glaucoma. Primaryopen-angle glaucoma Thisis the most co...
Water shoots up into the air in this “ultrasonic fountain”, which was created by focusing high-frequency sound on a small volume of water just beneath the water’s surface. The sound waves resulted in large pressure drops as they passed through the water, causing some regions to become so...
We initially focus on glaucoma, a condition often associated with raised intraocular pressure. The mechanics in this disease is by no means fully understood, but we present some of the modeling work that provides a partial explanation. We next focus on other features of the dynamics of the two...
Response to "Comment on: The role of intracranial pressure in glaucoma and therapeutic implications" Glaucomatous damage causes characteristic cupping of the optic nerve where it passes through the lamina cribrosa. There is evidence that cerebrospinal fluid (CSF) within the optic nerve sheath has a ...

The central nervous system is effectively isolated from the rest of the body. This physiological compartmentalization not only provides protection of its delicate function from aberrant peripheral influences but also impedes its diagnostic evaluation. Ce
Due to the elasticity of the walls, the fluidic channels can be inflated or collapsed to alter intracavity volume in response to the changes in liquid volume inside, similar to the way in-vivo vessels change sizes under different blood pressure. Specifically, the channel with soft walls ...
