Efficacy and Necessity of Time Interval Between Instillation of Two Glaucoma Eye Drops

According to the American Academy of Ophthalmology's Preferred Practice Pattern on Primary Open Angle Glaucoma, patients should wait five minutes between administering topical drops for intra-ocular pressure reduction. To date, no study has shown the efficacy of this waiting period. In this study, we aim to establish the clinical significance of keeping a time interval between glaucoma medications.
