Introduction: To determine whether a smartphone medical adherence application (app) (RxmindMe® Prescription/Medicine Reminder and Pill Tracker) can be used to improve compliance to treatment of amblyopia in patients 3-7 years of age.
Methods: Prospective, case-control study. Patients 3-7 years of age were randomized to receive electronic remainders (reminders group) or standard instructions (control group). Visual acuity and compliance with treatment was assessed at the follow up visit. The patient’s adherence with the prescribed treatment was calculated as the reported number of hours of patching performed divided by the number of hours prescribed or compliance percentage. The validated ‘Amblyopia treatment Index Parental Questionnaire’ was administered to the parent/guardian to assess the impact of patching treatment during the follow up appointment.|
Results: 23 patients were enrolled. Twelve children in the reminder group were compared with 11 in the control group. No significant differences were found between the two groups in terms of age (p=0.168), gender (p=0.684), visual acuity improvement (p=0.36), or percentage compliance (95% vs. 90%, p= 0.40).
Discussion: While some families felt they benefited from the reminder app, visual improvement and compliance was similar to standard treatment.
Conclusion: Our findings indicate that a smartphone reminder app can be used in this patient population in the treatment of amblyopia. Targeting the app to specific patient demographics or when difficulty with compliance is encountered needs to be further investigated.
