Abstract

Background: Commonly, two clinical techniques are used to measure the amplitude of accommodation: push-up and minus lens-to-blur approaches. However, there is no consensus on the accurate technique for assessing the accommodative amplitude in the clinical eye examination. Aim: This study was to compare push-up and minus lens-to-blur methods and Hofstetter's equations for assessing the amplitude of accommodation in Saudi university students. Methods: This was a comparative cross-sectional, performed in the department of optometry clinic between February and May 2020. The amplitude of accommodation was assessed on 79 Saudi young students (62 males and 17 females, mean age and standard deviation was 23.50 ± 2.29 years old using the push-up and minus lens-to-blur methods and calculated using Hofstetter's equations. Results: The findings showed that the highest mean of the amplitude of accommodation was found by using the Hofstetter's maximum equation (15.2 ± 0.9D), whereas the minus lens-to-blur technique provided the lowest result (8.6 ± 1.6D). Using the t-test, significant changes were seen between all methods P<0.0001 except the minus lens-to-blur method and Hofstetter's minimum equation P=0.077. Measurements by different methods revealed an opposite association between subjects' age and amplitude of accommodation. Conclusion: Given the significant variance in results obtained between the different techniques for measuring the amplitude of accommodation, caution should be taken once making decisions regarding amplitude accommodation assessment in young subjects with accommodative disorders and binocular vision abnormalities.
