Rod intercept

Web1 Feb 2016 · The rod-intercept is defined as the duration required for sensitivity to recover to a criterion sensitivity value of 5.0×10 −3 scotopic cd/m 2 (3.0 log units of attenuation of the stimulus). 26 The criterion sensitivity level is located in the latter half of the second component of rod recovery. 13 An increase in the rod-intercept is caused by a slowing of … WebFor the extended test (20-minute maximum duration), the rod intercept again increased with increased disease severity (P < 0.0001). The dark adaptation impairment measured for the AMD group was substantial. The mean rod intercept of the AMD group was 10 minutes greater than that of the normal group (P < 0.0001).

WebPurpose Quantification of dark adaptation (DA) response using the conventional rod intercept time (RIT) requires very long testing time and may not be measurable in the presence of impairments due to diseases such as age-related macular degeneration (AMD). The goal of this study was to investigate the advantages of using area under the DA curve … Web1 Feb 2016 · Eyes in the earliest phases of AMD were two times more likely to have delayed rod-mediated dark adaptation, as assessed by the rod-intercept, as compared to older eyes in normal macular health, whereas there was no difference in early AMD versus normal eyes in tests of visual acuity, low luminance acute, macular light sensitivity and spatial ... WebRod intercept time (RIT) was assessed after a 76%, 70%, and 65% rhodopsin bleach at 5° eccentricity and 76% and 70% bleach at 12°.
