This study will be used to evaluate how patients put eye drops in their eyes and any problems that may arise from this activity. The information gathered will help identify common problems patients are having with putting in their eye medications. Then doctors can be better informed about the issues and provide better advice to their patients to overcome these problems.

Approximately 100 patients will take part in a one time procedure and survey as part of this project. After appropriate consent patients are asked to complete a short 2 page survey about themselves and their eye drops. Then a video recording will be made of the patient instilling eye drops in their habitual manner. The eye drops used will be sterile saline placed in either Travatan-like or Systane bottles to simulate the corresponding prescribed medication. The videos will be graded for instillation technique and combined with scoring of survey answers.

Patients will be asked to instill the drops to their left eye with their dominant hand as we expect this to be most difficult. Patients with severe (>20/200) vision loss will instill drops into their better seeing eye.
