A retrospective review and observational study of outcomes and safety of bimatoprost ophthalmic solution 0.03% for treating eyelash hypotrichosis.

Background: The efficacy and safety of bimatoprost ophthalmic solution 0.03% for treating hypotrichosis were shown in a randomized controlled trial and in an open-label study. To date, no data on real-world experience have been published.

Objective: To evaluate long-term patient satisfaction, usage patterns, and safety of bimatoprost 0.03% in clinical practice.

Materials And Methods: In this retrospective chart review with a cross-sectional design, adult patients exposed to bimatoprost 0.03% for at least 12 months were randomly sampled from 16 investigational sites. Charts were reviewed for medication usage characteristics and adverse events (AEs). At a study visit, questionnaires eliciting patient-reported outcomes were administered and spontaneously reported AEs were tabulated.

Results: Analysis included 585 subjects with a mean (SD) treatment duration of 19.3 (4.3) months. Patient satisfaction with bimatoprost 0.03% was 92.5%; on average, approximately 3 applications per week maintained benefits. Overall, 27.4% of patients spontaneously recalled experiencing AEs while on treatment; however, patient charts showed that only 4 AEs were documented. No instances of iris hyperpigmentation occurred. No serious or severe AEs were noted.

Conclusion: Treatment with bimatoprost 0.03% for at least 12 months is safe, and long-term use is associated with a high degree of satisfaction.
