Which two tests are cited as necessary to diagnose accommodative dysfunction?

• A. Amps and MEM
• B. MEM and Nott
• C. Bell and MEM
• D. Nott and NRA

Answer: (A)

Diagnosing accommodative dysfunction relies on two key pieces: how much the eye can physically accommodate, and how accurately it responds to near demands. The amplitude of accommodation tests the maximum amount of lens power the eye can generate, revealing whether the capacity matches the patient’s near tasks or is abnormally reduced. The Monocular Estimation Method (MEM) assesses accommodative accuracy at near by measuring the actual response to a near stimulus—essentially whether the response lags or leads relative to the demand. Using both together gives a complete picture: amplitude shows the capacity limit, while MEM shows how closely the eye’s response matches the demand in real time. If amplitude is reduced, that points to a capacity issue; if MEM shows a lag while amplitude is normal, that points to an accuracy/response issue. This combination is why these two tests are cited as necessary for diagnosing accommodative dysfunction.
