Abstract: In certain embodiments, a system for assessing a floater in the eye of a patient includes a display device, input device, and computer. The display device displays a target and background. The background has an alignment point and alignment axis. The eye axis of the eye is substantially aligned with the alignment axis when the eye is fixating on the alignment point. The input device receives patient input from the patient. The computer provides target display input to the display device to yield the target moving according to a pattern for the eye to follow. The eye axis moves relative to the alignment axis as the eye follows the moving target. The computer records patient input indicating that the patient sees the floater. The computer calculates a severity score, which indicates the severity of the floater, according to the patient input and generates a report that describes the severity score.

Abstract: Embodiments disclosed herein provide devices, systems, and methods for reducing intraocular pressure. For example, the disclosed devices, systems, and methods are useful for reducing intraocular pressure resulting from conditions, such as acute glaucoma, on a short-term basis until a definitive surgical procedure is performed. More particularly, valved trocar cannula systems for reducing intraocular pressure resulting from conditions, such as acute glaucoma, pending surgical intervention in an operating room are disclosed. In practice, a trocar assembly is used to place a valved cannula assembly in a patient's eye, such as in the anterior chamber or pars plana, to reduce high intraocular pressure. The valved cannula is then left in the patient's eye for a period of time to continuously allow aqueous humor or liquid vitreous humor to flow therethrough, until the patient may be surgically treated in an operating room.
