increases.

There are three TGC setup options:

1.

Near - increases the gain for the anterior portion of 
the eye in the B-Scan image, near the probe

2.

Middle - increases the gain for the middle portion 
of the eye

3.

Far - increases the gain for the far portion of the 
eye

To adjust the TGC image scan presets slide the 
appropriate setting indicators as shown in Figure 56 
below.
