Eligibility

Inclusion criteria

Inclusion criteria: 50-70 years of age Presence of DPOAEs in one ear For healthy controls: Upright IOP of 21mmHg or lower For high pressure glaucoma: Diagnosed Glaucoma, upright IOP over 21mmHg before the onset of IOP lowering treatment, and established disease progression rate based on perimetry For normal tension glaucoma: Diagnosed Glaucoma, upright IOP of 21mmHg or lower with or without IOP lowering treatment, and established disease progression rate based on perimetry For high IOP with no glaucoma: Upright IOP of 22mmHg or higher Written informed consent.

Exclusion criteria

Exclusion criteria: No presence of DPOAEs For healthy controls, any eye disease or family history of glaucoma

Design outcomes

Primary

Measure	Time frame
The primary objective is to evaluate the use of DPOAEs as a representation of ICP in Glaucoma patients by investigating changes in DPOAE amplitudes and phase angles with changes in posture in subgroups of glaucoma patients and in healthy controls.	—
