assemblies and methods for modifying an intraocular pressure of a patient &# 39 ; 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 &# 39 ; s eye and wall surfaces of the goggle . controlling the pressure over the outer surfaces of the patient &# 39 ; s eye can drive a desired change in the intraocular pressure of the eye .
