Retinal Periphlebitis May Be a Marker for Subphenotype in Multiple Sclerosis

Area of Science:

• Ophthalmology
• Neurology
• Immunology

Background:

• Retinal periphlebitis (RPP) is a known complication in multiple sclerosis (MS).
• Recent advances in MS pathogenesis and heterogeneity warrant a re-evaluation of RPP.
• RPP's role in MS has not been extensively studied in light of new developments.

Purpose of the Study:

• To investigate retinal periphlebitis (RPP) in contemporary multiple sclerosis (MS) patients.
• To explore the potential of RPP as a marker for MS subphenotypes.
• To understand the immunopathological implications of RPP in MS.

Main Methods:

• Case series presentation of six MS patients with RPP.
• Clinical evaluation including ophthalmological examinations.
• Analysis of RPP in the context of MS characteristics and potential immunopathology.

Main Results:

• Six cases of RPP were identified in relapsing-remitting MS patients (3 female, 3 male).
• Most patients had minimal or no ocular symptoms, highlighting the need for thorough retinal screening.
• RPP involvement suggests potential distinct autoantigenic targets in MS immunopathology.

Conclusions:

• Retinal periphlebitis may be an underdiagnosed sign in MS patients, even with minor ocular symptoms.
• RPP could serve as a valuable subphenotype marker in MS, potentially influencing therapeutic strategies.
• Further research is essential to elucidate the full impact and implications of RPP in MS.
