Visual and Functional Assessment in Low Vision Patients

NCT01876147 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 50

No results posted yet for this study

Summary

Vision testing is a fundamental part of every optometry and ophthalmology assessment. Traditional vision testing charts are not able to measure vision below a certain level. Vision in this range is classified as counting fingers (CF), hand movements (HM) and light perception (LP). These measures are not very accurate or easily quantifiable. They are also poorly understood in terms of impact on quality of life. This study aims to assess new methods for measuring the vision of patients with very low vision.
