This study is a prospective comparative, randomized, single center study to gather agreement and precision data in all subjects.

Inclusion Criteria - Normal Group:

1. Male or female subjects 22 years of age or older who have full legal capacity to volunteer on the date the informed consent is signed;
2. Subjects who can follow the instructions by the clinical staff at the clinical site, and can attend examinations on the scheduled examination date;
3. Subjects who agree to participate in the study;

Exclusion Criteria - Normal Group:

1. Subjects unable to tolerate ophthalmic imaging;
2. Subjects with any current ocular pathology, as determined by self-report and confirmed by the investigator assessment and/or confirmed by the investigator assessment at the study visit;
3. Subjects that present with an active ocular infection in either eye;
4. Subjects who have a history of ocular surgery, including laser therapy/surgery;
5. Subjects with a condition or in a situation which the investigator feels may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the study.

Inclusion Criteria - Cataract Group:

1. Male or female subjects 22 years of age or older who have full legal capacity to volunteer on the date the informed consent is signed;
2. Subjects who can follow the instructions by the clinical staff at the clinical site, and can attend examinations on the scheduled examination date;
3. Subjects who agree to participate in the study;
4. Subjects diagnosed with cataract classified per the LOCS III scale;

Exclusion Criteria - Cataract Group:

1. Subjects unable to tolerate ophthalmic imaging;
2. Subjects with corneal or conjunctival abnormalities that may affect adequate assessment of the anterior chamber in either eye;
3. Subjects that present with an active ocular infection in either eye;
4. Subjects who have a history of ocular surgery, including laser therapy/surgery;
5. Subjects with a condition or in a situation which the investigator feels may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the study

Inclusion Criteria - Glaucoma Group:

1. Male or female subjects 22 years of age or older who have full legal capacity to volunteer on the date the informed consent is signed;

2. Subjects who can follow the instructions by the clinical staff at the clinical site, and can attend examinations on the scheduled examination date;

3. Subjects who agree to participate in the study;

4. Subjects with glaucomatous optic nerve damage as evidenced by any of the following optic disc or retinal nerve fiber layer structural abnormalities:

   1. Diffuse thinning, focal narrowing, or notching of the neuroretinal rim, especially at the inferior or superior poles with or without disc hemorrhage;
   2. Optic disc neural rim asymmetry of the two eyes consistent with loss of neural tissue

5. History of Visual field defects within the previous six (6) months from the study visit or measured the day of the study visit consistent with glaucomatous optic nerve damage with at least one of the following two findings:

   1. On pattern deviation (PD), there exists a cluster of 3 or more points in an expected location of the visual field depressed below the 5% level, at least 1 of which is depressed below the 1% level;
   2. Glaucoma hemi-field test "outside normal limits."

Exclusion Criteria - Glaucoma Group:

1. Subjects unable to tolerate ophthalmic imaging;
2. Subjects with corneal or conjunctival abnormalities that may affect adequate assessment of the anterior chamber in either eye;
3. Subjects that present with an active ocular infection in either eye;
4. No reliable Humphrey Field Analyzer (HFA) visual field (24-2 Sita Standard, white on white) result within 6 months of the study visit, defined as fixation losses > 33% or false positives > 33%, or false negatives > 33% in the study eye;
5. Subjects with a condition or in a situation which the investigator feels may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the study.
