High-pass resolution perimetry in uncomplicated myopia

Area of Science:

• Ophthalmology
• Visual Neuroscience

Background:

• Myopia, a common refractive error, can affect visual function beyond simple blur.
• Understanding subtle visual field changes in myopia is crucial for comprehensive eye care.

Purpose of the Study:

• To investigate visual field characteristics in subjects with uncomplicated myopia.
• To assess the correlation between the degree of myopia and visual field parameters.

Main Methods:

• Utilized high-pass resolution perimetry and Goldmann perimetry.
• Examined 15 subjects (28 eyes) with myopia ranging from 3 to 9 diopters.

Main Results:

• A slight increase in mean resolution threshold was observed in the central 30-degree field, significantly correlated with myopia degree.
• Eight subjects (10 eyes) exhibited increased thresholds in the Goldmann visual fields, specifically around the blind spot.
• Only one subject (one eye) showed a corresponding abnormality in the resolution fields.

Conclusions:

• Visual field testing, including high-pass resolution perimetry, may detect subtle functional changes in uncomplicated myopia.
• These findings suggest potential alterations in visual processing or retinal sensitivity related to myopia severity.
