Abstract

The relationship between accommodative fluctuations and perimetric sensitivity was investigated in a group of 10 clinically normal emmetropic subjects using the Dicon AP3000 computer-assisted perimeter at a bowl luminance of 10 asb. Accommodative microfluctuations were attenuated with the antimuscarinic drug cyclopentolate HCl 1% and the concomitant mydriasis was matched on a separate trial using the sympathomimetic phenylephrine HCl 10%. Saline 0.9% was used as the control. Accommodative microfluctuations were found to play a minor role in determining the magnitude of sensitivity out to an eccentricity of 5 degrees; between 5 degrees and 27.5 degrees, the effect of microfluctuations was masked by the mydriasis produced by the drugs used in the study. The range of sensitivity values at a given location were reduced when accommodative fluctuations were minimized.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
