Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients of either sex, any race, aged over 50 years and over, diagnosed with exudative (wet) AMD in one eye (non-study eye) and non-exudative (dry) AMD (intermediate or large/confluent drusen, with hyperpigmentation, and no CNV or geographic atrophy) in the other eye (study eye) that is at risk for progressing to exudative (wet) AMD and meet all the inclusion and exclusion criteria.

You may qualify if:

  • Written informed consent
  • Age over 50 years
  • Any race and any sex
  • Clinical diagnosis of exudative AM;D in one eye (non-stud eye) and the presence of the following characteristics in the second eye (study eye, eye to be treated):
  • At least 5 or more intermediate (\> 63 µm) or larger soft drusen AND/OR Confluent drusen within 3000 µm of the fovea center
  • Hyperpigmentation

You may not qualify if:

  • History of medical condition that would preclude scheduled study visits
  • History of ophthalmic disease in the study eye other than AMD
  • Clinical signs of myopic retinopathy, or refraction higher than -8 diopter power.
  • Intraocular surgery in the study eye within 60 days prior enrollement
  • Evidence of past or present CNV in the study eye
