[Variability of sensitivity thresholds in short-wavelength automated perimetry (SWAP) in the central vision field].
OBJECTIVE
To determine the distribution of sensitivity thresholds of short-wavelength automated perimetry (SWAP) in the central visual field, analysing their variability depending on the eccentricity, in normal subjects.


METHODS
128 eyes of 128 normal subjects were analyzed. They underwent a SWAP examination. A lineal regression model was used to establish a <<standard visual field>> (SVF). The SVF determines the threshold distribution and its variability.


RESULTS
The regression analysis obtained a SVF, age-corrected, which considers the influence of age in the different points of the visual field. The threshold distribution showed higher inter-subject deviations as eccentricity increased (p<0.001).


CONCLUSIONS
The determination of variability of the threshold sensitivity deviations in the different points of the central visual field allows future development of perimetric algorythms for SWAP.
