Subject's adherence to prescribed therapy will be monitored with an electronic compliance device.
Device: MEMS cap
The Medication Event Monitoring System will be used to assess the level of subject adherence to recommended topical eye drop therapy.
Other Name: MEMS

Primary Outcome Measures :
  1. Medication adherence measured by MEMS caps [ Time Frame: 3 months ]
  2. Eye drop technique measured by video evaluation [ Time Frame: 1 time observation ]

Secondary Outcome Measures :
  1. Medication adherence measured by self-report [ Time Frame: 3 months ]
  2. Severity of VF damage [ Time Frame: 1 test date ]
  3. Intraocular pressure readings [ Time Frame: 3 months ]
