- History of uveitis in either eye
- Ocular disorders in the study eye that may confound interpretation of study results, compromise visual acuity or require medical or surgical intervention during the 12-month study period, including retinal vascular occlusion, retinal detachment, macular hole, or choroidal neovascularization of any cause (e.g., age-related macular degeneration, ocular histoplasmosis, or pathologic myopia)
- Uncontrolled glaucoma in the study eye (according to investigator's judgment)

- Ocular conditions in the study eye that require chronic concomitant therapy with topical ocular or systemically administered corticosteroids
- Systemic conditions or treatments
- History of disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug, might affect the interpretation of the results of the study, or renders the patient at high risk from treatment complications
- Renal failure requiring dialysis or renal transplant OR renal insufficiency with creatinine levels \>2.0 mg/dl
- Untreated diabetes mellitus
- Severe (blood pressure systolic \> 160 mmHg OR diastolic \> 100 mmHg) AND untreated hypertension
