Objective: To determine the normative values of the amplitude of accommodation (AA) with four subjective procedures. Materials and methods: 586 students between the ages of 5 and 19 from public schools in Pereira were included. AA was measured by means of the Donders (push up [PU], push down [PD] and modified push down [MPD]) and Sheard (minus lens [ML]) methods. Results: The average for the entire age group was: PU: 14.58 D; PD: 9.55 D; MPD: 12.01 D; ML: 11.00 D; in addition, the change of the AA for age was estimated through linear regression: PU: 0.25 D; PD: 0.03 D; MPD: 0.10 D; ML: 0.09 D. Conclusions: AA is different with each technique, and when compared to studies conducted outside of Colombia; furthermore, AA decrease is not similar in these tests. |
