Studies Comparing Tests for Presbyopic Add Power: A Literature Review.
The conventional treatment for presbyopia is the prescription of additional plus for nearpoint viewing. This paper reviews studies which have provided data on the mean differences between the add powers recommended by various tests and guidelines, and it reviews studies which have reported data on t...

This paper reviews studies which have provided data on the mean differences between the add powers recommended by various tests and guidelines, and it reviews studies which have reported data on the mean differences between the adds from such tests and a preferred or prescribed add. Most of the studies also reported coefficients of agreement (COA), which represent a measure of the variability of the differences, or provided the data to make the calculation of them possible. Tests and guidelines studied include binocular cross cylinder, keep half the amplitude in reserve, balance negative relative accommodation and positive relative accommodation, nearpoint red/green test, plus build-up test, and age-expected add. The low mean differences between these tests and the preferred or prescribed add suggest that they are all reasonable starting points with which to establish a tentative add. However, the magnitudes of the COAs suggest that these tentative adds be modified or confirmed based on factors such as patient history, previous prescription, symptoms, visual needs, and other test results. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
