Age-Corrected Normal Values for Perimetry

Abstract

Purpose: Age-corrected values are indispensable in assessing discrete changes in light difference sensitivity (LDS) when evaluating perimetric results. In order to detect incipient visual field defects, the present study aimed particularly to determine function of normal values depending on age and eccentricity. Methods: A test group (n = 83) of ophthalmologically and clinically unremarkable subjects 18–74 years of age was examined with the ‘Centerfield’ perimeter. A brief introductory program was first used to familiarize each test person with the situation. Then values in the central visual field (30Results: Age-related normal values were calculated both as group averages and as lines of regression by statistical analysis of the resulting data. In contrast to other perimetric studies, decreases in LDS at different test points for persons aged 20 years to persons over 60 were not linear. Conclusions: Age-related normal values should be reviewed for other perimeters.

The Tölz Temporal Topography Study: Mapping the visual field across the life span. Part I: The topography of light detection and temporal-information processing

“…Age also affected perimetric luminance thresholds, as was expected on the basis of previous normative data (Becker, Vonthein, Volpe, & Schiefer, 2005; Wohlrab, Erb, & Rohrbach, 2002). Mean luminance thresholds increased with age [ANOVA: F(7, 86) = 12.46, p < .001, η 2 = .50], with participants in their 60s, 70s, and 80s, in particular, having significantly higher average perimetric thresholds than the remainder of the sample.…”

Compass: Clinical Evaluation of a New Instrument for the Diagnosis of Glaucoma

“…For Compass, the mean decrease was -0.048 dB / year for the foveal and perifoveal areas, and -0.045 dB / year for the central 10°. For HFA, other published sources report a mean decrease of-0.047 dB / year for the foveal area [ 15 ] and of-0.041 dB / year for the central 10° [ 14 ].…”

Detection of visual field defects in pre-perimetric glaucoma using fundus-oriented small-target perimetry

“…A study by Leeprechanon et al [22] showed an AROC of second-generation FDT and SWAP in the detection of PPG (0.74 for MD of SWAP and 0.67 for PSD of FDT). Brusini et al [12] reported that optimal specificity was found in detecting early glaucomatous visual field defects when at least one area with a non-hit rate of [70 % was used as a cutoff criterion An age-related decline in sensitivity was reported [12,[14][15][16][17][18], and the decline with aging was even more pronounced using a smaller target [8]. Salvetat et al [24] reported a normative range for rarebit perimetry and showed a significant inverse linear relationship between the mean hit rate and age.…”

“…An age-related decline of sensitivity in the visual field was reported previously [14][15][16][17][18]. From the 60 normal participants, we selected control subjects matched for age (average difference of ±5 years) and sex for comparison with the PPG and POAG groups.…”
