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).
A pressure assembly to adjust cavity fluid pressure in a cavity to treat an eye condition of a patient based on a determined translaminar pressure gradient (TPG), the TPG being a pressure difference between biosensor-measured intraocular pressure (IOP) and separately and independently biosensor-measured cerebrospinal fluid pressure (CSFP), the cavity defined by an enclosure sized and shaped to fit over a patient eye without contacting a surface of the patient eye, the pressure assembly comprising:
