Which type of tonometry would most likely be used for patients with corneal irregularities?

• A. Goldmann tonometry
• B. Rebound tonometry
• C. Non-contact tonometry
• D. Dynamic contour tonometry

Answer: (D)

Dynamic contour tonometry is particularly suitable for patients with corneal irregularities because it measures intraocular pressure (IOP) in a way that is less influenced by the shape and stiffness of the cornea. Unlike other tonometry methods that rely on flattening the cornea to gauge pressure, dynamic contour tonometry uses a contour-based approach that aligns with the shape of the corneal surface. This allows for a more accurate measurement of IOP in individuals whose corneas may be irregularly shaped due to conditions like keratoconus or previous corneal surgeries. The other types of tonometry may not provide reliable readings in these cases, as they can be affected by the corneal morphology and biomechanical properties. Therefore, dynamic contour tonometry stands out as the most reliable option when dealing with corneal irregularities.
