Conditions
Outcome Measures
Primary Outcomes (1)
Highest Vitreous Humor Level of Brimonidine in the Study Eye
The highest level of brimonidine measured in the vitreous humor of the study eye in any patient is reported for each treatment arm. The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye.
60 Days
Secondary Outcomes (2)
Highest Aqueous Humor Level of Brimonidine in the Study Eye
60 Days
Percentage of Patient Samples With Plasma Levels of Brimonidine Below the Limit of Quantitation (BLQ)
60 Days
Study Arms (2)
400 µg Brimonidine Tartrate Implant
EXPERIMENTAL400 µg brimonidine tartrate implant in the study eye on Day 1 (2, 4 or 8 weeks prior to undergoing a pars plana vitrectomy).
200 µg Brimonidine Tartrate Implant
EXPERIMENTAL200 µg brimonidine tartrate implant in the study eye on Day 1 (2, 4 or 8 weeks prior to undergoing a pars plana vitrectomy).
Interventions
400 µg brimonidine tartrate implant in the study eye on Day 1 (2, 4 or 8 weeks prior to undergoing a pars plana vitrectomy).
200 µg brimonidine tartrate implant in the study eye on Day 1 (2, 4 or 8 weeks prior to undergoing a pars plana vitrectomy).
Eligibility Criteria
You may qualify if:
- Plan on having a pars plana vitrectomy for repair of a posterior segment condition (eg, epiretinal membrane, macular hole, vitreomacular traction)
- Visual acuity in the non-study eye better than 20/200
You may not qualify if:
- History of pars plana vitrectomy or retinal detachment surgery in the study eye
- Surgery or laser treatment in the study eye within 3 months
- Use of brimonidine, apraclonidine or other topical alpha-2-agonist in either eye within 2 weeks
- Intraocular infection or inflammation
