[Color vision under different luminosity in various fundus diseases]

Area of Science:

• Ophthalmology
• Medical Diagnostics

Background:

• Color vision testing is utilized for detecting early fundus disease abnormalities.
• The 100-hue test assesses color vision, but optimal testing conditions require investigation.

Purpose of the Study:

• To determine the adequate luminosity for performing the 100-hue test.
• To assess the correlation between color vision disorder and the progression of specific fundus diseases.

Main Methods:

• The 100-hue test was administered at five luminosity levels (10-2000 lux) to patients with glaucoma, diabetic retinopathy, and central chorioretinopathy.
• Disease progression was classified using visual acuity, visual field, C/D ratio (glaucoma), retinopathy type, and disease duration (diabetic retinopathy).

Main Results:

• A close correlation was observed between the total error score of the 100-hue test and the degree of disease progression.
• The most effective luminosity for performing the 100-hue test was determined to be 100 lux.

Conclusions:

• The 100-hue test is a valuable tool for detecting early abnormalities in fundus diseases.
• Performing the 100-hue test at 100 lux optimizes its diagnostic capability for glaucoma, diabetic retinopathy, and central chorioretinopathy.
