Endpoint of BAF?

Endpoint of BAF?

• A. Clear +/- 2.50 without suppression for 20 cpm
• B. Clear +/- 1.50 without suppression for 20 cpm
• C. Clear +/- 3.50 for 40 cpm
• D. Clear +/- 2.50 with suppression for 30 cpm

Answer: (A)

In this test, the endpoint is reached when the patient can sustain a clear, single image with both eyes (no suppression) under a moderate stimulation condition. The criterion used is a binocularly clear perception with a tolerance of about ±2.50 at a stimulation rate of 20 cycles per minute. This reflects completing the binocular fusion task under typical demands while ensuring the eyes are contributing together rather than one being suppressed. That’s why the best choice is the option stating clear ±2.50 without suppression for 20 cpm. The other options either require suppression, or use different stimulation rates, which don’t meet the standard endpoint criteria for this measure.
