A new grayscale octotype was developed to detect subtle visual changes. This tool aids in identifying early functional decline in conditions like maculopathies and neuritis.

Area of Science:

  • Ophthalmology
  • Visual Science

Background:

  • Assessing minimal visual changes is crucial for early disease detection.
  • Maculopathies and neuritis can cause subtle functional vision impairments.

Purpose of the Study:

  • To introduce a novel octotype with a grayscale for evaluating minimal visual alterations.
  • To highlight the utility of this instrument in detecting early functional worsening.

Main Methods:

  • Development of a specialized octotype incorporating a grayscale.
  • Utilizing the octotype for the evaluation of visual changes.

Main Results:

  • The grayscale octotype enables the assessment of minimal visual changes.
  • The instrument is effective in detecting subtle functional decline.

Conclusions:

  • The developed octotype is a valuable tool for ophthalmological assessments.
  • It assists in the early detection of functional worsening in maculopathies and neuritis.
