Inclusion Criteria: * At least one eye diagnosed with acquired blepharoptosis and presence of all the following criteria at screening: * Loss of reliable Leicester Peripheral Field Test (LPFT) of ≥ 8 points in the top 2 rows (LPFT Eligibility Score); subjects had to see at least 9 total points in the top 4 rows (LPFT Total Score). * This criterion had to be met in both the Visit 1 Hour 0 (V1H0) and Visit 1 Hour 6 (V1H6) LPFT assessments. * There had to be ≤4 points of variance between the V1H0 and the V1H6 LPFT Eligibility Score. * The Marginal Reflex Distance-1 (MRD-1), the distance from the pupil center to the margin of upper lid, ≤ 2 mm (no visible pupil center defaults to 0) in the same eye * Visual acuity is 0.25 decimals (i.e., Snellen 20/80) or better according to standard logarithmic visual acuity chart in the same eye * Presence of all the following criteria at baseline: * Loss of reliable LPFT of ≥8 points in the top 2 rows (LPFT Eligibility Score) in the same eye; subjects had to see at least 9 total points in the top 4 rows (LPFT Total Score). * This criterion had to be met in the Visit 2 Hour 0 (V2H0) LPFT assessment * There had to be ≤4 points of variance between the V1H6 and the V2H0 LPFT Eligibility Score; * The MRD-1, the distance from the pupil center to the margin of upper lid, ≤ 2 mm (no visible pupil center defaults to 0) in the same eye * Visual acuity is 0.25 decimals (i.e., Snellen 20/80) or better according to standard logarithmic visual acuity chart in the same eye * Female subjects are 1-year postmenopausal, surgically sterilized, or females of childbearing potential (females who had started their menstrual cycles) with a negative urine pregnancy test at screening. Females of childbearing potential had to use an acceptable form of contraception throughout the study. Exclusion Criteria: In the study eye * Dermatochalasis that extended less than 3 mm above the upper eyelid margin. * Pseudoptosis (upper eyelid dermatochalasis that overhung the upper eyelid margin). * In either eye: Congenital ptosis; Horner syndrome; Marcus Gunn jaw-winking syndrome; Myasthenia gravis. * Mechanical ptosis, including ptosis due to orbital or lid tumour, cicatricial processes affecting the movements of the upper lid, and enophthalmos. * Previous ptosis surgery (previous blepharoplasty \[only\] was allowed provided the surgery took place \> 3 months prior to screening). * Lid position affected by lid or conjunctival scarring; Visual field loss from any cause other than ptosis; History of herpes keratitis. * History of closed/narrow angle glaucoma (unless patent peripheral iridotomy had been performed \> 3 months prior to screening). * Periocular neurotoxin (e.g., Botox®, Dysport®) injections within 3 months prior to screening and during the study. * Topical application of bimatoprost (i.e., Latisse®) to the eyelashes within 7 days prior to screening and during the study. * Use of topical ophthalmic medications including but not limited to anti-allergy \[e.g., antihistamines like Emadine®, Patanol®\], dry eye \[e.g., Diquas®, Beifushu®; except artificial tears like Hyaluronate\], antimicrobial drugs \[e.g., antibiotics and antivirals like Cravit®,Tobrex®, Aciclovir\], and anti-inflammatory drugs * Current punctal plugs or placement of punctal plugs during the study. * Current use of over-the-counter (OTC) vasoconstrictor/decongestant eye medication or any ophthalmic or non-ophthalmic α-adrenergic agonist including OTC products at any time during the study.
