Tendency Oriented Perimetry (TOP) significantly reduces visual field test time compared to Octopus 32. However, TOP may be less accurate in calculating scotoma depth.

Area of Science:

  • Ophthalmology
  • Visual field testing

Background:

  • Visual field testing is crucial for diagnosing and monitoring glaucoma.
  • Traditional perimetry methods can be time-consuming.

Purpose of the Study:

  • To evaluate the capabilities of the new Tendency Oriented Perimetry (TOP) strategy on the Octopus visual field analyzer.
  • To compare TOP with the standard Octopus 32 strategy.

Main Methods:

  • 79 visual fields were analyzed using Octopus 32 and TOP strategies.
  • Participants included normal visual field/glaucoma suspects, and patients with moderate to advanced glaucoma.
  • Parameters assessed included examination time, mean sensitivity (MS), mean defect (MD), Loss Variance (LV), and short-term fluctuation (RF).

Main Results:

Related Experiment Videos

  • TOP significantly reduced examination time (2.49 minutes) compared to Octopus 32 (11.87 minutes) (p < 0.001).
  • No significant differences were found in MS, MD, or RF between the two strategies.
  • Loss Variance (LV) showed significant modification in global and group analyses.

Conclusions:

  • Tendency Oriented Perimetry (TOP) offers a substantial reduction in visual field examination time.
  • TOP appears less accurate than standard Octopus 32 perimetry, particularly for calculating scotoma depth.
