■Quantitative measurement of protein concentration in aqueous humor with high accuracy using
the laser scattering technique
■Clinical tests for uveitis and other ocular inflammations, and to monitor post cataract surgery
■Non-contact and non-invasive testing
An area including the measurement window is scanned with a laser beam. Background signal 1 (BG1) is obtained when the laser beam is located below the measurement window and background signal 2 (BG2) is obtained when the laserbeam is located above the measurement window. Both are scattered light noise from intraocular tissue, whilst the flare signal (SIG) is a sum of scattered light from protein and scattered light noise from intraocular tissue.
Thus, the intensity of the scattered light caused by the protein concentration in the aqueous humor of the anterior chamber is calculated using the formula: SIG-(BG1+BG2)/2. The result obtained from using this formula is called ‘flare value’ and represented as photon count per millisecond.
The KOWA FM-700 is classified Class 1 laser product.
