9 Weak scattered light induced by laser beam entered into the anterior chamber is detected and used for measurements. It is known that intensity of the scattered light is proportional to the protein level contained in aqueous humor of the anterior chamber. However, intensity of the scattered light may vary if there is a difference in the protein co[...]

20 Points for alignment 1. Measurement window must be between the left and right laser beams. 2. Measurement window must be located below the Spot light. 3. Measurement window and the right laser beam must be within the pupil. Points for operation It is recommended to tilt the joy stick lightly in diagonal directions while monitoring Diagonal view [...]

21 BG level indicator BG check finds out the uniformity of background lights by determining the back- ground lights around Measurement window. Level of the uniformity appears in Measurement window shown in the display. This is what we call “BG level indi- cator”. Details are shown in Figure 9. Level 5 is the highest level that indicates backgro[...]
