For measuring a large angle strabismus, how should additional prisms be added during testing?

Stacked in the same direction
In opposite directions over each eye
Randomly over both eyes
Only the most powerful prism should be used

The correct answer is: In opposite directions over each eye

When measuring a large angle strabismus, adding additional prisms in opposite directions over each eye is the correct approach because it allows for the simultaneous evaluation of how each eye's visual axis can be adjusted. This technique helps in determining the amount of deviation and the necessary correction needed to align the eyes properly. Using prisms in opposite directions provides a more accurate assessment of the strabismus, as it isolates the effect of the prisms on each eye's line of sight. This method also effectively neutralizes the deviation by using the principles of prism integration, allowing the examiner to gauge the total deviation and make informed decisions regarding treatment options. In contrast, stacking prisms in the same direction would not provide an accurate measurement of alignment as it would overly amplify the deviation instead of compensating for it. Randomly placing prisms would lack a systematic approach and could lead to inconsistent results. Limiting to only the most powerful prism without considering the effects of multiple prisms can overlook critical data necessary for proper assessment and management of strabismus.
