Short-Listing the Program Choice for Perimetry in Neurological Conditions (PoPiN) Using Consensus Methods

Area of Science:

• Neuro-ophthalmology
• Visual field testing
• Neurological disorders

Background:

• Neurological conditions often lead to visual field loss, necessitating perimetry tests.
• Current lack of national guidelines for perimetry in neurological conditions.
• Inappropriate perimetry program selection can result in missed visual field loss.

Purpose of the Study:

• Determine preferred perimetry programs for visual field loss detection in four neurological conditions.
• Inform the development of research and clinical practice guidelines for neuro-ophthalmology.

Main Methods:

• Survey of 47 perimetry programs among orthoptists and neuro-ophthalmologists.
• Consensus meeting using nominal group technique to identify top-ranked programs.
• Evaluation of program suitability for idiopathic intracranial hypertension, optic neuropathies, chiasmal compression, and stroke.

Main Results:

• Nine perimetry programs were deemed not applicable.
• Short-lists for conditions ranged from six to ten programs.
• Consensus identified three preferred programs for idiopathic intracranial hypertension, optic neuropathies, and chiasmal compression (manual/semi manual kinetic, static 30-2, full-field 120).
• Consensus identified three preferred programs for stroke (manual/semi manual kinetic, static 30-2, monocular Esterman).

Conclusions:

• A thorough exploration of perimetry programs was conducted using survey and consensus methods.
• Clinician preferences for perimetry programs in neuro-ophthalmic practice were established.
• The three most favored perimetry programs for four key neurological conditions were determined.
