 CLIP Strategy |  From staircase to elevator

CLIP (Continuous Light Increment Perimetry) follows a radically different path. In contrast to the regular bracketing methods, CLIP makes use of test points with luminance increased at a steady rate. As a result, test duration is drastically shortened. Also, reproducibility of the results is increased. In addition, convenient side effect, satisfaction level is kept high. This unique real threshold test that outperforms most interpolation based algorithms is now available in all OCULUS perimeters.
In the case of CLIP, the test stimulus is always “on”,its luminance being increased in time in smaller steps (usually 1 dB), until the patient gives a positive answer.
By measuring the average reaction time of the patient and choosing the appropriate incremental rate of the luminance, a significant reduction of the examination time can be achieved, without losing precision or reproducibility.
The fact that a stimulus with increasing luminance in the end is always observed generates elevated patient comfort. |
