Microperimetry outcomes. (Left) The differential light sensitivity (dB; DLS) at each of 56 stimulus locations is superimposed upon the spectral-domain optical coherence tomography en-face infrared fundus image. The lesion is demarcated (horizontal white lines) from the volumetric B-scans (horizontal green lines). The DLS value is colour coded, using a continuous scale of colour change, to arbitrarily indicate normal (green), borderline (yellow or orange) and abnormal outcomes (red). This colour coding does not take into account the variation of DLS in the normal eye with age or with eccentricity. (Right) The corresponding visual field Pattern Deviation probability maps derived for the study, were referenced to normative data (i.e. accounting for age and eccentricity). Locations exhibiting an abnormal sensitivity at a probability level of <5% < 2% or <1%, respectively, are indicated. The axes show the eccentricity in degrees. m = microns.
