Values obtained during initial examination (baseline). Laser flare photometry measurements were not obtained on every patient at initial examination.
Number of eyes for which data were available. For some patients with bilateral disease, measurements could not be obtained for both eyes.
Initial values obtained at an examination after baseline, if laser flare photometry was not performed at baseline.
For patient who had follow-up and who had laser flare photometry measurements at multiple examinations.
Calculated by subtracting baseline flare value or first flare value from most recent flare value.
The absolute difference between the highest and lowest flare values for each patient with follow-up who had multiple laser flare photometry measurements.
The highest flare value obtained for each patient, regardless of when during the course of disease.
Calculated by adding duration of disease before baseline and interval from baseline to examination at which maximum flare obtained. If the duration of uveitis before baseline was unknown, the patient was assigned the value “0” for study purposes.
