Classification of semi-automated flare readings using the Kowa FM 700 laser cell flare meter in patients with uveitis.

Purpose To propose a classification system to grade semi-automated flare readings and assess its correlation with clinical flare grading and also to explore the utility of an additional step in clinical flare assessment between grades 0 and 1. Methods Semi-automated flare readings from 103 eyes with uveitis were taken using the Kowa FM 700 laser flare meter and classified into two models ( LFCM and LFCM_1), and introduction of a 0.5 step in flare grading was explored. Results Good correlation was present between the conventional SUN clinical flare and the proposed clinical classification for flare (weighted kappa ( WK) = 89.64%, p < 0.001). Semi-automated flare grading ( LFCM and LFCM_1) had WK agreement of 82.52% and 79.85% (p < 0.001) with conventional SUN clinical flare grading. Conclusions The proposed classification system for semi-automated laser flare readings ( LFCM) allows stratification of measurements into grades analogous to clinical flare grades and correlates well with conventional clinical flare grading.
