A standardized grading system for limbal stem cell deficiency

Welcome to the VaHI grading tool

Limbal stem cell deficiency (LSCD) results from a range of pathologies such as chemical burns and aniridia. While the repertoire of treatment techniques expands and the number of limbal cell therapies grows, there is still a lack of objective outcome measures in grading this pathology. The different assessment techniques and subjective parameters challenge the grading of LSCD severity and impede objective comparison of treatment outcomes.

VaHI stands for Vascularisation, Haze and Integrity; 3 key clinical signs of LSCD. Grading different clinical signs related to LSCD allows a simple way of documenting the severity of the condition and in evaluating outcomes after treatment.

The VaHI software provides a new, improved and easy grading system for assessing and grading LSCD eyes. Feel welcome to discover this tool and join us for some simple and straightforward grading.
