Embodiment Construction

[0032] figure 1 A shows a cross-section of an example of a human eye 100 . Eye 100 includes two chambers within sclera 122 : anterior chamber 104 and posterior chamber 116 . The anterior chamber 104 is generally defined as the space between the cornea 102 and the iris 106 and is filled with aqueous humor. Pupil 107 is the hole defined by iris 106 that allows light to enter eye 100 . Lens 110 is positioned behind iris 106 and is supported by ligaments 112 . The ciliary process 114 , which includes the ciliary body and ciliary muscle, surrounds the lens 110 and is positioned behind the iris 106 .

[0033] The posterior chamber 116, located between the anterior chamber 104 and the retina 120, is filled with the vitreous. Retina 120 is structurally and physiologically supported by choroid 123 located between retina 120 and sclera 122 .

[0034] Anterior chamber 104 and posterior chamber 116 are collectively referred to as the intraocular space of eye 100 . The anterior chamb...

Abstract

An apparatus for at least one of diagnosing or treating an eye condition can include a goggle enclosure, sized and shaped to be seated on an eye socket of an eye to provide one or more cavities withinthe enclosure that extend about an entire exposed anterior portion of the eye, a pump, in fluidic communication with the one or more cavities to apply a fluid pressure to t he one or more cavities, the pump configured to adjust a fluid pressure within the one or more cavities of the goggle enclosure, and a control circuit, including a data interface to receive data directly or indirectly indicating at least one of an intraorbital pressure, ICP, IOP, or a relationship between ICP and IOP, and based on processing the received data as a feedback control variable, controlling the pump to adjust the fluid pressure within the one or more cavities, the controlling including using further monitoring of the received data to control the pump.

Description

[0001] priority claim [0002] This patent application claims U.S. Provisional Patent Application Serial No. 62 / 210,751 of Berdahl, filed August 27, 2015, entitled "Detecting Intrabody Pressure Using Eye Blood Vessel Characteristic" and filed March 21, 2016, entitled "Apparatus and Methods for Ocular Pressure Modification," Berdahl's U.S. Provisional Patent Application Serial No. 62 / 311,052, both of which are incorporated herein by reference in their entirety. Background technique [0003] Measuring intraocular pressure is important for diagnosing and treating eye diseases such as glaucoma. Early diagnosis and treatment of glaucoma are key to curb or prevent vision loss. Non-contact tonometers are useful instruments for measuring intraocular pressure, but can cause discomfort to the patient when used. [0004] US Patent 4,724,843 mentions a tonometer capable of directing a controlled puff of air onto the cornea. [0005] US Patent 5,523,808 mentions a compound ophthalmic de...
