The art of perimetry

Area of Science:

• Ophthalmology
• Neuroscience
• Psychophysics

Background:

• Perimetry is a crucial diagnostic tool for assessing visual field defects.
• Current perimetric methods are subjective and vary in applicability.
• The need for objective, standardized perimetric techniques is recognized.

Observation:

• Perimetric examination is a subjective, psychophysical sensory test.
• No single perimetric method suits all visual field defects.
• Objective measurement of visual evoked response (VER) is not yet clinically standard.

Findings:

• The selection and application of perimetric techniques depend on the clinician's judgment.
• Accurate perimetry relies on the perimetrist's understanding of the patient's condition.
• The practice of perimetry involves both scientific technique and clinical art.

Implications:

• Clinicians must skillfully choose and apply perimetric methods for accurate diagnosis.
• The development of objective perimetry could enhance diagnostic precision.
• Understanding the 'art of perimetry' is essential for effective visual field assessment.
