A tonometry technique that displaces a minimal amount of fluid is

  1. Goldmann

  2. Non-contact

  3. Rebound

  4. Applanation

The correct answer is: Applanation

Applanation tonometry is a technique that measures the intraocular pressure by flattening a small area of the cornea. It involves minimal fluid displacement compared to other tonometry techniques. The other options, such as Goldmann, non-contact, and rebound tonometry, involve different principles and are not specifically designed to displace minimal fluid during the measurement of intraocular pressure.
