title: [The difference between right and left eyes in the values obtained with a laser flare-cell meter].
abstract: The difference in various values, measured with a laser flare cell meter (FC1000: KOWA), between the right and left eyes was determined in 28 eyes of 14 healthy males, 18 to 23 years of age (group A), and in 60 eyes of 30 out-patients, 6 to 68 years of age (group B). None of the eyes had any ocular pathology except for refractive error. Both groups of eyes were first evaluated without any treatment, and the eyes in group A were measured again after the instillation of mydriatics. The flare, signal, and background values were all statistically higher in the right eye than in the left in all subjects; the difference in the flare value between the two eyes was approximately 1 photon count/millisecond on the average. A regression analysis of the difference of the signal and the background values between the two eyes suggests that variation of the light scattered from behind the iris is responsible for the difference in the flare intensity between the right and the left eyes.
