Advanced Dry AMD With Geographic Atrophy Clinical Trial
Official title:
Repeatability and Reproducibility of Cirrus HD-OCT Measurements of Illumination Areas Under the Retinal Pigment Epithelium
The objective of this study is to determine the repeatability and reproducibility of the Cirrus HD-OCT measurement of illumination areas under the retinal pigment epithelium (RPE).
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 illumination areas under the RPE will be determined. In Phase 2, the inter-operator variability of Cirrus HD-OCT measurements of illumination areas under the RPE 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. ;
Observational Model: Case-Only, Time Perspective: Prospective
