Abstract
PURPOSE: To evaluate the correlation between longitudinal changes in aqueous flare measured by laser flare photometer (LFP), best-corrected visual acuity (BCVA), and clinical grade using both Standardization of Uveitis Nomenclature (SUN) and modified SUN (MSUN) scales uveitis patients. METHODS: Patients were classified according to both SUN and MSUN grading scales. LFP measurements were acquired (Kowa FM-700) at each visit. Mean change in LFP was assessed longitudinally, comparing with those in visual acuity, SUN, and MSUN grading scales. RESULTS: Mean change in LFP was correlated to those in BCVA (p = .018), SUN scale (p < .001), and MSUN scale (p = .008). Cases within same initial SUN (0 and 1+) and MSUN (0.5+ and 1+) grades and different longitudinal flare prognosis (decreased/unchanged/increased) had significantly different initial LFP values (all p < .05). CONCLUSIONS: LFP measurement is beneficial in monitoring inflammatory activity. Cases of identical clinical flare scores with different clinical prognosis may be predicted by LFP.
