Plain-language summary
The investigators wish to better understand the role of the choriocapillaris (CC) in the formation and progression of non-exudative in age related macular degeneration (armd) by imaging the retinal pigment epithelium (rpe) and the choroidal microvasculature and by studying their inter-dependence to determine if the loss of the CC could prove useful as an anatomic clinical trial endpoint in future drug trials.

Inclusion Criteria:
* Enrollment in and completion of the BIRC-01 study

* Provide signed informed consent
Exclusion Criteria:
* Subjects with exudative AMD in both eyes
* Eyes with evidence of non-proliferative and proliferative diabetic retinopathy.
* Presence of confounding ocular diagnosis such as myopia \>6D, or other ocular conditions that may cause retinal pigment epithelium atrophy or exudative MNV
