Unequal pupils. A flow chart for sorting out the anisocorias

Area of Science:

• Ophthalmology
• Neurology

Background:

• Anisocoria, or unequal pupils, is a common clinical sign indicating a potential neurological or ocular issue.
• Diagnosing the underlying cause of anisocoria can be complex due to the variety of possible lesions and conditions.

Purpose of the Study:

• To present a structured, step-by-step diagnostic flowchart for evaluating patients with anisocoria.
• To aid ophthalmologists and clinicians in efficiently localizing the lesion responsible for unequal pupils.

Main Methods:

• Development of a diagnostic algorithm based on clinical signs and symptoms.
• Inclusion of explanations for various physical examination findings.
• Description of relevant diagnostic tests for differential diagnosis.

Main Results:

• A clear, sequential flowchart designed to guide the diagnostic process for anisocoria.
• Detailed explanations of key indicators and their diagnostic implications.
• Recommendations for appropriate investigations to confirm diagnoses.

Conclusions:

• The proposed flowchart simplifies the diagnostic approach to anisocoria.
• Effective utilization of the flowchart can improve the accuracy and speed of diagnosis for unequal pupils.
