Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The proposed human clinical studies have three main objectives: 1. To determine reproducibility of peripapillary birefringence maps and identify features that measure the health of the RNFL. 2. To determine the normal variation in the birefringence maps with age. 3. To develop and test a classifier for glaucoma based on the birefringence maps using a case-control clinical trial. This study is a case-control study intended to optimize feature selection for a future multi-center blinded study. The proposed clinical study does not measure conversion from normal to glaucoma.
