ABSTRACT
PURPOSE:
To correlate fixation stability and retinal sensitivity measured by liquid crystal display (LCD) microperimetry to visual acuity in eyes with macular pathology.DESIGN:
Retrospective chart reviewMETHODS:
The cohort included 26 eyes of 26 patients, divided into two groups according to visual acuity (Group 1 eyes 6/15 - 6/48, Group 2 < or = 6/60). Macular sensitivity and fixation stability were measured using the LCD microperimeter. Mean retinal sensitivity (at central 12 degrees) and fixation stability (at 2 degrees and 4 degrees) were correlated with best-corrected visual acuity.RESULTS:
Mean retinal sensitivity correlated with the visual acuity in both groups [Group 1 eyes 28 point central 12 degrees (9.0 dB); Group 2 central 12 degrees (4.183 dB)] (P < 0.05). The fixation stability correlated similarly with the visual acuity for the groups [Group 1 eyes 2 degrees (81.2%) and 4 degrees (94.6%); Group 2 eyes 2 degrees (44.1%) and 4 degrees (80.7%] (P < 0.05).CONCLUSION:
In the present study, the mean retinal sensitivity and fixation stability measured with LCD microperimeter correlated with visual acuity. LCD microperimetry reliably measures fixation stability and retinal sensitivity in eyes with various macular pathologies.
