Study Comparing the P200TE and the P200TxE

The objective of this study is to collect OCT scans to compare the qualitative B scan images
produced by the P200TxE to the P200TE device on a variety of subjects with ocular disease and
no ocular disease. Usability feedback from operator and clinician will be collected.

visit as confirmed by the investigator;

Exclusion Criteria - Normal Group:

- Subjects unable to tolerate ophthalmic imaging;

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

investigator;

Exclusion Criteria - Glaucoma Group:

- Subjects unable to tolerate ophthalmic imaging;

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

self-report and/or investigator assessment on the day of the study visit.

- Subjects with history of dementia or multiple sclerosis.

- Subjects who are not reliably tested with at least one Humphrey Field Analyzer (HFA)
visual field (24-2 or 30-2, white on white) measured on the day of the study visit or
within the previous six (6) months from the study visit, defined as fixation losses >
20% or false positives > 33%, or false negatives > 33%;
