Lamina Cribrosa Depth Change With Change in Eye Pressure
Not Applicable
Completed
- Conditions
- Glaucoma, Open-Angle
- Interventions
- Other: wearing swimming goggles or having laser suturelysis
- Registration Number
- NCT03267849
- Lead Sponsor
- Johns Hopkins University
- Brief Summary
This is a study of the compliance of the lamina cribrosa with change in eye pressure.
- Detailed Description
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
