Which test is used to measure intraocular pressure?

• A. Tonometry
• B. Visual acuity testing
• C. Slit-lamp exam
• D. Fundoscopy

Answer: (A)

Measuring intraocular pressure is done with tonometry. This test estimates the pressure inside the eye by assessing how the cornea responds to a small applied force. The most common method, applanation tonometry, flattens a tiny area of the cornea to determine the pressure needed to do so. Other variants include rebound tonometry and non-contact air-puff tonometry. Visual acuity testing, slit-lamp examination, and fundoscopy provide information about vision clarity, anterior structures, and the retina/optic nerve, but they do not measure eye pressure. Tonometry is the method used to measure intraocular pressure.
