Study to Compare Kowa OCT Bi-μ and the Optovue iVue 100

Inclusion Criteria (Normal Group):

- Subjects with normal eye examinations (without pathology other than cataract) in one
or both eyes on the date of the study visit;

- Subjects with intraocular pressure (IOP) ≤ 21 mmHg in the normal eye(s) on the date of
the study visit; and

- Subjects with current best-spectacle-corrected visual acuity (BSCVA) of 20/40 or
better in the normal eye(s) on the date the study visit.

Exclusion Criteria (Normal Group):

- Subjects unable to tolerate ophthalmic imaging;

- Subjects with ocular media not sufficiently clear to obtain acceptable OCT images;

- Subjects with 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;

- Subjects with current narrow anterior chamber drainage angle in the normal eye(s), as
determined by self-report and/or investigator assessment at the study visit; and

- Subjects with a history of leukemia, dementia or multiple sclerosis.

Inclusion Criteria (Glaucoma Group):

- Subjects who have been diagnosed with glaucoma in the glaucoma study eye(s), with
optic nerve damage as evidenced by either of the following optic disc or retinal nerve
fiber layer structural abnormalities observed via fundus exam during the study visit:

1. Diffuse thinning, focal narrowing, or notching of the optic disc rim, especially
at the inferior or superior poles with or without disc hemorrhage; or

2. Optic disc neural rim asymmetry of the two eyes consistent with loss of neural
tissue;

- Subjects with a current BSCVA of 20/40 or better in the glaucoma study eye(s) on the
date of the visit; and

- History of visual field defects within the previous two (2) months from the study
visit or measured on the day of the study visit that is consistent with glaucomatous
optic nerve damage based on at least one of the following 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; and

2. Glaucoma hemi-field test "outside normal limits."

Exclusion Criteria (Glaucoma Group):

- Subjects unable to tolerate ophthalmic imaging;

- Subjects with ocular media not sufficiently clear to obtain acceptable OCT images;

- Subjects with at least one Humphrey Field Analyzer (HFA) visual field (24-2 SITA
Standard, white on white) measured on the day of the study visit, or within the
previous two (2) months from the study visit with unreliable results, defined as
fixation losses > 20%, or false positives > 33%, or false negatives > 33% in the
glaucoma study eye(s);

- Subjects with any current ocular pathology except glaucoma in the glaucoma study
eye(s), as determined by self-report and/or investigator assessment on the day of the
study visit; and

- Subjects with a history of leukemia, dementia or multiple sclerosis.

Inclusion Criteria (Retinal Disease Group):

- Subjects with current IOP ≤ 21 mmHg in the retinal disease study eye(s) on the day of
the study visit;

- Subjects with a current BSCVA of 20/400 or better in the retinal disease study eye(s)
at the study visit; and

- Subjects diagnosed with retinal pathology including but not limited to: Macular
Degeneration, Diabetic Macular Edema, Diabetic Retinopathy, Macular Hole, Epiretinal
Membrane, Cystoid Macular Edema, and others in the retinal disease study eye(s) as
confirmed within the past six (6) months.

Exclusion Criteria (Retinal Disease Group):

- Subjects unable to tolerate ophthalmic imaging;

- Subjects with ocular media not sufficiently clear to obtain acceptable OCT images;

- Subjects with glaucoma or any ocular pathology other than retinal pathology (e.g.
cornea pathology) in the retinal disease study eye(s), as determined by self-report
and/or investigator assessment at the study visit;

- Subjects with current narrow anterior chamber drainage angle in the retinal disease
study eye(s), as determined by self-report and/or investigator assessment at the study
visit; and

- Subjects with a history of leukemia, dementia or multiple sclerosis.
