Description

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.

Official Title

Non Exudative Age-Related Macular Degeneration Imaged With Swept Source Optical Coherence Tomography: The Extension Study

Details

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. This is an extension of a currently ongoing longitudinal observational study (BIRC-01) (NCT03688243).

  • Provide signed informed consent

You CAN'T join if...

  • 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
  • Subjects currently or previously enrolled in other interventional clinical trials in which treatment was administered to the study eye.
  • Previous vitrectomy or intravitreal injections in the study eye.
  • Axial length measurement ≥ 26 mm.
