Study Arms (4)

Normal Group:

(1)Subjects presenting at the site with normal eyes bilaterally (cataracts are acceptable). (2)IOP ≤ 21 mmHg bilaterally; BCVA 20/40 or better bilaterally. (3) No history of corneal, glaucoma, or retinal diseases. (4)No history of ocular surgeries, including laser refractive surgery, cataract surgery, glaucoma surgery and retinal surgery. (5)Subjects without any current ocular pathology other than cataract in the normal eye(s), as determined by self-report and/or investigator assessment at the study visit.

Device: Vision-700

Glaucoma Group

(1) With a current BCVA of 20/40 or better in the glaucoma study eyes. (2) History of visual field defects within the previous six months from the study visit or measured on the day of the study visit that is consistent with glaucomatous optic nerve damage. (3) Subjects who have been diagnosed with glaucoma in the glaucoma study eyes based on the presence of visual field defects, regardless of the optic nerve head and RNFL appearance. (4) Subjects without retinal disease or cornea condition in the glaucoma study eyes, as determined by self-report and/or investigator assessment at the study visit.

Device: Vision-700

Retinal Disease Group

(1)Subjects with a current BCVA of 20/400 or better in the retinal disease study eye(s) at the study visit. (2)Subjects diagnosed with retinal pathology including but not limited to any one of following criteria: a. Non Exudative Macular Degeneration (dry AMD), Diabetic Macular Edema, Macular Hole, Epiretinal Membrane, Cystoid Macular Edema, or other retinal disease in the study eye(s) as confirmed within the past six months, who exhibit structural lesions in the study eye; b. Neovascular Macular Degeneration (wet AMD), Diabetic Retinopathy, Retinal Artery Occlusion, Retinal Vein Occlusion or other retinal disease in the study eye(s) as confirmed within the past six months, who exhibit vascular and/or ischemic lesions in the study eye. (3) Subjects without glaucoma or cornea condition in the retinal disease study eye(s), as determined by self-report and/or investigator assessment at the study visit.

Device: Vision-700

Cornea Condition Group

History of refractive surgery, contact lens (wear contact lens more than 6 months), dry eye or keratoconus.

Device: Vision-700
