Abstract: Described here are systems and methods for accessing Schlemm's canal and for delivering an ocular device, tool, or fluid composition therein. The ocular devices may maintain the patency of Schlemm's canal without substantially interfering with transmural fluid flow across the canal. The fluid composition may be a viscoelastic fluid that is delivered into the canal to facilitate drainage of aqueous humor by disrupting the canal and surrounding trabeculocanalicular tissues. Some systems described here may be configured to cut or tear the trabecular meshwork with the body of an elongate member located within Schlemm's canal. Other tools for disrupting these tissues and minimally invasive methods for treating medical conditions associated with elevated intraocular pressure, including glaucoma, are also described.

Abstract: A method for augmenting a physical display with an extended reality display. A processor receives first signals representative of a first object fully presented on a physical display, second signals representative of a second object having a first portion presented on the physical display and a second portion extending beyond a border of the physical display, and third signals representative of a third object initially presented on the physical display and subsequently wholly moved beyond the border of the physical display. In response to receiving the second signals, the second portion is presented via a wearable extended reality appliance in a virtual space while the first portion is presented on the physical display. In response to receiving the third signals, the third object is wholly presented via the wearable extended reality appliance in the virtual space following the third object having been wholly presented on the physical display.
