Interferometer is used to test a patient's

Eye pressure
Field of vision
Retinal health
Potential acuity

The correct answer is: Potential acuity

An interferometer is a device that is used to measure the potential visual acuity of a patient. It is commonly utilized in ophthalmic practice to assess the patient's ability to see fine details and determine their potential vision with or without correction. Through the interference patterns created by the light passing through the device, the interferometer can help in evaluating the patient's visual acuity accurately. Eye pressure, field of vision, and retinal health are important aspects of a comprehensive eye examination, but they are not typically assessed using an interferometer. Instead, these parameters are evaluated through specific tests such as tonometry for measuring intraocular pressure, perimetry for assessing the visual field, and various imaging techniques for evaluating retinal health.
