Primary Open Angle Glaucoma
Conditions
Brief summary
To assess the safety and performance of the MIDI Arrow in patients suffering from glaucoma that is inadequately controlled on maximum tolerated medical therapy with intraocular pressure ≥ 18 mm Hg and ≤ 40 mm Hg
Detailed description
This will be a monocentric, non-randomized, single arm clinical study in which each patient meeting the inclusion criteria and not excluded per the exclusion criteria will be implanted with a MIDI Arrow in the anterior chamber of the eye. Patients will be followed for at least 24 months with an expected enrollment period of up to 24 months. Safety of the shunt will be evaluated with indirect and direct microscopic evaluation of the implanted and non-implanted eyes pre and post operatively, and at defined follow-up intervals for hypotony, inflammation, infection, migration of the shunt, visual acuity, as well as a number of other defined potential complications. The effectiveness of the shunt will be evaluated by measurement of intraocular pressure at defined intervals.

Outcome results
Number of Eyes With Study Success
The rate of success reflected sustained control of IOP over 24 Months from baseline
Time frame: Months 6, 9, 12 and 24
Population: The Intent-to-Treat (ITT) population included all enrolled eyes who have signed the informed consent and attended the procedure visit to receive the assigned therapy under evaluation (MIDI Arrow).
| Arm | Measure | Group | Value (COUNT_OF_UNITS) |
|---|---|---|---|
| Success With Respect to IOP | Number of Eyes With Study Success | Month 6 | 50 Implanted eyes |

IOP Change From Baseline
Intraocular Pressure (IOP) change in studied eye compared to baseline value at all timepoints thru 24 Months.
