Detailed Description
Participants who fulfill the study eligibility criteria and who are planned to undergo a pars plana vitrectomy will be enrolled in the study. Eligible participants scheduled for a diagnostic vitrectomy may also be enrolled.
The study will consist of two stages:
Stage One - Open label dose escalation:
Up to three subsequent dose-escalation groups will receive Laquinimod eye drops for 2 weeks and samples will be assayed for Laquinimod concentration in aqueous humor, vitreous and plasma.
Stage Two- Randomized, Controlled Comparison of 2 Laquinimod doses:
After the dose escalation cohorts are analysed, 2 Laquinimod doses will be selected for a randomized comparison. The doses in stage 2 will not exceed those studied in stage 1.
