Patients w/ active intraocular inflammation (eg, uveitis); inflammatory ocular conditions, neovascular, inflammatory, angle-closure, congenital or narrow-angle glaucoma; preexisting or history of CV disease (eg, CHD, Prinzmetal's angina 1st degree heart block & cardiac failure); hypotension; severe peripheral circulatory disturbance/disorders (ie, Raynaud's phenomenon); mild or moderate COPD; corneal disease. History of atopy or severe anaphylactic reactions. Aphakic, pseudophakic patients w/ torn posterior lens capsule or w/ known risk factors for macular edema (eg, intraocular surgery, retinal vein occlusions, ocular inflammatory disease & diabetic retinopathy); diabetics (especially those w/ labile diabetes). May mask signs of hyperthyroidism or acute hypoglycemia; induce dryness of eyes. Cardiac disorders. Choroidal detachment. Potential permanent increased brown iris pigmentation, periocular skin & eyelash darkening; periorbital tissue pigmentation; potential for hair growth in skin surface w/ repeated contact w/ soln. May decrease IOP-lowering effect w/ frequent exposure of >1 dose daily. Monitor for IOP changes in patients using other prostaglandin analogs. Concomitant use w/ systemic β-adrenergic blocking agents. May impair compensatory tachycardia & increase risk of hypotension w/ anesth. Remove contact lenses prior to administration & reinsert at least 15 min after instillation. May have negligible influence on ability to drive and use machines. Renal or hepatic impairment.
