Lamina Cribrosa Depth Change With Change in Eye Pressure

Lamina Cribrosa Depth Change With Change in Eye Pressure

This is a study of the compliance of the lamina cribrosa with change in eye pressure.

Glaucoma patients and control subjects will have their internal eye structure (lamina cribrosa) imaged by optical coherence tomography (OCT) standard images at two different eye pressures. In some participants, the eye pressure will be changed by one of two interventions, wearing goggles or having laser suturelysis

Inclusion Criteria:

• persons who consent to drink water and be imaged

Exclusion Criteria:

• non-consenting persons
