A new two-digit stimulus value (SV) system simplifies Goldmann perimetry target selection and data analysis. This standardized approach enhances examiner efficiency and computer compatibility for visual field testing.

Area of Science:

Ophthalmology
Visual field testing
Perimetry

Background:

The Goldmann perimeter is a standard for visual field assessment.
Current Goldmann perimetry methods can be complex for target selection and data recording.
A need exists for a more simplified and standardized approach.

Purpose of the Study:

To propose a simplified nomenclature for Goldmann perimetry.
To introduce a two-digit stimulus value (SV) system.
To enhance the usability of Goldmann perimetry for examiners and computer analysis.

Main Methods:

Adoption of a two-digit stimulus value (SV) nomenclature.
Standardization of target area luminance and contrast.
Application on a Goldmann-type perimeter.

Main Results:

The proposed SV system simplifies target selection.
It aids in mental interpolation and isopter construction.
Facilitates computer manipulation of visual field data.

Conclusions:

The two-digit SV nomenclature offers a return to Goldmann's intended simplicity.
This system improves examiner efficiency and data standardization.
It provides a foundation for enhanced computer integration in perimetry.
