Asset Details

  • Description:
  • The Amsler chart consists of a grid with vertical and horizontal lines with a fixation dot in the center. If we use a chart with only vertical lines and a fixation dot, we can represent the patient's view (Figure 4). With an MH and the displacement of the retina, the brain's image of straight lines is bent toward the center (the pincushion distortion) and the fixation dot is not seen by the patient with an MH (the central scotoma). This agrees well with the main characteristic of metamorphopsia in patients with an MH as a pincushion distortion with a defect of the central visual field. The central dot in the chart cannot be recognized because of the MH, although most patients can point out the central dot by eccentric fixation.
