PMOS 1% First, Then PMOS Vehicle
Participant received Phentolamine Mesylate Ophthalmic Solution 1%: 1% phentolamine mesylate ophthalmic solution (Nyxol), a non-selective alpha-1 and alpha-2 adrenergic antagonist at Visit 1. Then, after one week, they received Phentolamine Mesylate Ophthalmic Solution Vehicle (Placebo): Topical Sterile Ophthalmic Solution at Visit 2. 1 drop in each eye, 1 hour post medically-induced mydriasis at both visits.
PMOS Vehicle First, Then PMOS 1%
Participants received Phentolamine Mesylate Ophthalmic Solution Vehicle (Placebo): Topical Sterile Ophthalmic Solution at Visit 1. Then, after one week, they received Phentolamine Mesylate Ophthalmic Solution 1%: 1% phentolamine mesylate ophthalmic solution (Nyxol), a non-selective alpha-1 and alpha-2 adrenergic antagonist at Visit 2. 1 drop in each eye, 1 hour post medically-induced mydriasis for both visits.
