Subjective Patient Assessment Comparing Overall Tolerability and Satisfaction of a Prostaglandin Analogue Including Either Bimatoprost 0.01% or Latanoprost.

Tolerability of Medications as Measured by the COMTOL Validated Instrument

时间窗: at the time of enrollment in the clinic, patients will immediately complete the questionnaire and exit the study

Patients who are already taking the medications of interest will be enrolled from a general ophthalmology practice. Immediately after consenting to participate, they will complete a validated survey instrument called the Comparison of Ophthalmic Medication for Primary Outcome Measure Tolerability (COMTOL) questionnaire (Ophthalmology 1997; : 104:334-342). Because this study will not be a crossover trial design, and patients will only continue taking the medications they were prescribed in the course of their glaucoma therapy, the modified version will eliminate questions in the COMTOL related to subjective comparison of two medications and instead focus on tolerability of the single medication being taken by test subjects.
