Grading Protocols

Grading protocols are developed for specific studies depending on the study goals.  SIRC currently uses the following grading protocols:

AMD

The Complications of AMD Prevention Trial (CAPT) grading protocol quantifies drusen, changes in drusen over time, and describes exudation (late AMD).  For a general overview of the CAPT grading protocol click here [PDF currently unavailable].

The Comparison of Age-related Macular Degeneration Treatments Trials (CATT) grading protocol to be added soon.

For a Glossary of Terms Used in Grading AMD see "Glossary of Terms".
