Gaze-Evoked Intraocular Pressure Change in Glaucoma

The primary aim of this study is to evaluate the effect of upgaze on patients with POAG and NTG. Secondary aims of this study will include stratification based on severity of glaucoma or prior surgical interventions, and presence or absence of Bell’s phenomenon.

Inclusion Criteria:

- Subjects in the primary POAG or NTG arms must be diagnosed by NYEE glaucoma attendings.

- Subjects in the control arm must not carry a diagnosis of glaucoma of any kind, ocular hypertension, or corneal disease which may affect IOP measurements.

- All subjects must be 18 years old or older, and be willing to have the IOP measured up to 6 times.

Exclusion Criteria: 

- Subjects will be excluded from participation if they have a prior diagnosis of thyroid eye disease, restrictive myopathy, asymmetric proptosis of >2mm or exophthalmometer measurements >24mm in either eye as measured by Hertel exophthalmometry, limitation of eye movements on ductions, or intolerance to intraocular pressure measurement.

Conditions:
• Glaucoma
