Participant Flow

This study used an eye-based unit of analysis, where each eye with ptosis served as an individual study unit. Participants with bilateral ptosis contributed two eyes to the study, while those with unilateral ptosis contributed one eye. This was a single-arm study in which all recruited eyes progressed sequentially through identical interventions and assessments as described in the Arm/Group Description.

This study used an eye-based unit of analysis, where each eye with ptosis served as an individual study unit. Participants with bilateral ptosis contributed two eyes to the study, while those with unilateral ptosis contributed one eye. All affected eyes underwent identical interventions and assessments in a single arm, sequential design as outlined below. Study Protocol: Each eye with ptosis underwent the following sequential interventions and assessments: 1. Baseline measurements: Superior visual field (SVF) testing and margin reflex distance 1 (MRD1) measurements were performed with the eyelid in its natural position. 2. Eyelid taping intervention: The upper eyelid was manually elevated using adhesive tape, and SVF testing was repeated. 3. Phenylephrine intervention: One drop of 2.5% phenylephrine ophthalmic solution was instilled into the affected eye, followed by both SVF testing and MRD1 measurements. The total duration for each participant was less than 60 minutes across all testing conditions. Post-Study Assessment: Following completion of all interventions, participants completed a satisfaction questionnaire using a 5-point Likert scale to evaluate their experience with both eyelid taping and phenylephrine administration.

PRIMARY outcome

Timeframe: Baseline, Within 1 minute after upper eyelid taping.

Insurance SVF criteria for determining if ptosis is functionally significant are based on the absolute SVF height in primary gaze (a superior visual field of 30 degrees or less from fixation at baseline) and the difference in SVF demonstrated by taping of the upper eyelids (improvement of at least 12 degrees in the superior visual field compared to baseline). Here we assessed the count of units, with units being eyes, that demonstrated an improvement of at least 12 degrees in superior visual field between baseline and taping of the upper eyelid.
