A Modified NEI Grading Scale for Corneal Fluorescein Staining w/ Dr. Ken Sall

A Modified NEI Grading Scale for Corneal Fluorescein Staining

Dr. Ken Sall and Dr. Andrew Pucker discuss why a new, modified NEI grading scale for corneal fluorescein staining shows efficacy when the original scale does not. Dr. Sall explains the history of cornea grading, the common methodologies for grading and the advantage of the new scale, including inter- and intra-examiner repeatability. The new methodology, pioneered by Lexitas Pharma Services, can be useful for anterior segment ophthalmology clinical trials and was borne out of a need for more accurate grading during studies.
