Abstract: Argyll Robertson pupils (ARP) are a unique pupillary abnormality characterized by bilateral small pupils that do not react to light but constrict during near accommodation. This article provides a comprehensive review of ARP, exploring its diverse etiology, clinical significance, diagnostic approaches, management strategies, and recent innovations. By enhancing our understanding of ARP, ophthalmologists can improve diagnostic accuracy and optimize management for patients presenting with this intriguing pupillary phenomenon.

Introduction: Argyll Robertson pupils present a diagnostic challenge due to their association with various underlying etiologies, including neurosyphilis, diabetes mellitus, and other neurological conditions. Recognizing the clinical significance and underlying pathology is essential for appropriate management.

Etiology: ARP can occur secondary to neurological diseases affecting the pupillary pathways, such as neurosyphilis, multiple sclerosis, and diabetic neuropathy. Additionally, ARP may result from pharmacological causes, including certain medications and toxic substances. Understanding the diverse etiologies is crucial for determining the underlying cause and guiding further evaluation.

Clinical Significance: ARP are considered a hallmark finding of neurosyphilis, particularly in the context of posterior uveitis and optic neuropathy. However, ARP can also manifest in other neurological conditions, indicating dysfunction within the pupillary pathways. Recognizing ARP prompts further investigation for associated neurological and systemic disorders.

Diagnostic Approaches: Diagnosis of ARP involves a thorough ophthalmic and neurological evaluation, including assessment of pupillary light responses, near reflex, visual acuity, and fundoscopic examination. Confirmation of neurosyphilis often requires serological testing for Treponema pallidum antibodies, cerebrospinal fluid analysis, and neuroimaging studies.

Management Strategies: Management of ARP focuses on treating the underlying cause, such as initiating antibiotic therapy for neurosyphilis or optimizing glycemic control in diabetic neuropathy. Close monitoring of visual function and neurological status is essential for assessing treatment response and detecting disease progression.

Recent Advances: Recent research in ARP has focused on elucidating the pathophysiological mechanisms underlying this pupillary abnormality and exploring novel diagnostic and therapeutic strategies. Advances in neuroimaging techniques, serological assays, and targeted therapies offer promising avenues for improving diagnostic accuracy and treatment outcomes in ARP.

Conclusion: Argyll Robertson pupils represent a distinctive clinical finding with diverse etiologies and implications for underlying neurological and systemic diseases. By staying informed about the latest research and innovations in ARP, ophthalmologists can provide comprehensive care to patients, facilitating timely diagnosis and appropriate management.
