What is it about?
A single impression of the ocular surface can be treated like a tissue biopsy by a technique using frozen sectioning and immunohistochemistry. This technique was used to highlight the lack of correspondence between typical clinical tests used to assess ocular surface disease.

Why is it important?
If clinicians choose only a single clinical test to assess dry eye and ocular surface disease, the results have a high likelihood of being ambiguous.
Perspectives
Busy clinicians and their patients can benefit from diagnostic tools that are objective, reproducible, as well as both time and cost efficient. Continuing to search for such tools is important.
