  • Publication number: 20230414101
    Abstract: An apparatus to treat, inhibit, or prevent an eye condition in a patient can include a cover, sized and shaped to fit over an eye of a patient to define a cavity between the cover and an anterior surface of the eye when the cover is located over the patient eye. The apparatus can include a pressure source, in communication with the cavity, capable of applying non-ambient pressure in the cavity. The apparatus can include control circuitry, in communication with the pressure source, configured to vary non-ambient pressure applied to the cavity to affect a targeted pressure relationship between an indication of a first physiological pressure level and a second physiological pressure level associated with the eye of the patient.

  • Publication number: 20230043903
    Abstract: Assemblies and methods for modifying an intraocular pressure of a patient's one or both eyes are disclosed. The assemblies and methods can be used to treat, inhibit, or prevent ocular conditions such as glaucoma, high intraocular pressure, optic disc edema, idiopathic intracranial hypertension, zero-gravity induced papilledema, and other optic pressure related conditions. An assembly can include a goggle including at least one cavity, a pump in fluid communication with the at least one cavity, and a control mechanism. The control mechanism can be operatively coupled to the pump and can maintain a target pressure or target pressure range in the at least one cavity, which, when the assembly is worn by a patient, is the area between a patient's eye(s) and wall surfaces of the goggle. Controlling the pressure over the outer surfaces of the patient's eye(s) can drive a desired change in the intraocular pressure of the eye(s).

  • Publication number: 20210106492
    Abstract: An apparatus can include a left cover, sized and shaped to fit over a left eye of a patient to define a left cavity between the left cover and an anterior surface of the left eye and a right cover, sized and shaped to fit over a right eye of the patient to define a right cavity between the right cover and an anterior surface of the right eye. The apparatus can include a left pressure source to apply a left working fluid to the left cavity, the left pressure source capable of generating a left cavity pressure including a left negative gauge pressure and a right pressure source to apply a right working fluid to the right cavity, the right pressure source capable of generating a right cavity pressure including a right negative gauge pressure, where the right pressure source can be separate from the left pressure source.

  • Patent number: 10960074
    Abstract: A process for treating glaucoma whereby the treatment can be accomplished by the use of medication or by surgery, or both, in order to control or prevent the occurrence of glaucoma. The optic nerve is aligned within and between two distinct pressurized spaces and within the dural sheath, the intraocular space and the intracranial space having an intraocular pressure (IOP) and an intracranial pressure (ICP), respectively. Medicine can be administered to raise the intracranial pressure in order to reach a desirable lower translaminar pressure difference across these two pressurized spaces which are separated by the lamina cribrosa in order to treat glaucoma. An alternate closely related mode of the treatment process is the implanting of a shunt substantially between the intraocular space and the intracranial space in order to beneficially equalize pressure differentials across the intraocular space and the intracranial space.
