About

The objective of this study is to determine the repeatability and reproducibility of the Cirrus HD-OCT measurements of drusen area and volume.

Full description

This is a prospective, single site study. Ocular history and examination will be conducted on consented subjects to determine further participation in the study. The study will be divided into two phases. In Phase 1, the inter-device variability of Cirrus HD-OCT measurements of drusen area and volume will be determined. In Phase 2, the inter-operator variability of Cirrus HD-OCT measurements of drusen area and volume will be determined. In each of these phases, the Macular Cube 200 x 200 scan and the Macular Cube 512 x 128 scan will be evaluated.

Enrollment: 54 patients

Sex: All

Ages: 50+ years old

Volunteers: No Healthy Volunteers

4. Able and willing to give consent and follow study instructions.

Exclusion criteria
