Seeing eye doctor for routine care

You may qualify if:

  • Normal - No glaucoma or treatment to lower IOP or retinal pathology for posterior imaging; No contact lens wear, dry eye, anterior pathology or ocular surgery for corneal imaging.
  • Glaucoma - Have glaucoma and no history of other retinal pathology.
