[Computerized perimetry in neuro-ophthalmologic diagnosis].

Area of Science:

• Ophthalmology
• Neurology
• Visual Neuroscience

Context:

• Computerized static perimetry is a key diagnostic tool for the extrabulbar afferent visual system.
• Optic neuropathies present unique challenges in visual field assessment.
• Evaluating the efficacy of therapeutic interventions requires reliable diagnostic methods.

Purpose:

• To highlight the advantages of computerized static perimetry over kinetic methods for diagnosing visual system disorders.
• To detail the benefits of static perimetry in early defect recognition and objective disease monitoring.
• To discuss the limitations of computer-controlled automatic perimetry, including examination duration and potential for false positives.

Summary:

• Computerized static perimetry excels in diagnosing extrabulbar afferent visual system lesions, especially optic neuropathies.
• It enables early detection of relative visual field defects, like low-density scotomas, and provides examiner-independent results for disease progression tracking and therapy evaluation.
• Potential drawbacks include prolonged examination times and susceptibility to patient fatigue or suboptimal testing conditions, leading to false-positive findings.

Impact:

• Improves diagnostic accuracy for visual field defects in optic neuropathies.
• Facilitates objective monitoring of disease progression and treatment effectiveness.
• Provides insights into pathogenesis classification for certain visual disorders.
