ClinConnect Summary

Study Objectives and Purpose:

Part A - AS-OCT repeatability and agreement

1. The primary purpose of Part A is to compare the repeatability of the Cirrus with the Visante AS-OCT imaging system.
2. The second objective is to identify the level of agreement in the tear meniscus measurements taken by the Cirrus and Visante AS-OCT.

Part B - Tear evaporimetry with functional infra-red thermography

1. To evaluate the repeatability of Infrared thermography for ocular surface temperature measurements that are used for calculation of tear evaporation rates. If this is found to be acceptable, it w...
