Brief summary
A single centre, open label, study to assess the safety, tolerability and biodegradation of
PA5108 ocular implant in adults who have Open Angle Glaucoma (Primary or Secondary).
Participants who are currently managing their Open Angle Glaucoma with combination drop
therapy will be recruited. Drop therapy will cease in the treatment eye and continue in the
contralateral eye. The treated eye will receive via injection, a single PA5108 ocular
implant. Participants will be monitored for safety and tolerability of the ocular implant
until it completely biodegrades.
