[Retinal periphlebitis in multiple sclerosis. A prospective study]
1Servicio de Neurología, Universitària de la Vall d'Hebron, Barcelona.
Abstract:
Twenty-four patients with clinically defined multiple sclerosis were prospectively studied with the aim of establishing the frequency of retinal periphlebitis. In three cases (12.5%) retinal periphlebitis was observed. None of the patients with multiple sclerosis and retinal periphlebitis presented a severe form or progressive course of the disease; however, in one patient it caused complete unilateral amaurosis. Aggressive immunosuppressive treatment was effective in one case. Given the absence of myelin in the retina, the presence of retinal periphlebitis suggests the existence of a vascular mechanism in the pathogenesis of multiple sclerosis.
Insights
Retinal periphlebitis occurred in 12.5% of multiple sclerosis patients, suggesting a vascular role in disease pathogenesis. Though not linked to severe disease, it can cause vision loss, but responds to immunosuppressive treatment.
Area of Science:
- Ophthalmology
- Neurology
- Immunology
Context:
- Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system.
- Retinal periphlebitis, inflammation of the retinal blood vessels, is a known ocular manifestation in some neurological conditions.
Purpose:
- To determine the frequency of retinal periphlebitis in patients with clinically defined multiple sclerosis.
- To explore the potential link between retinal periphlebitis and the pathogenesis of multiple sclerosis.
Summary:
- Twenty-four patients with multiple sclerosis were prospectively evaluated for retinal periphlebitis.
- Retinal periphlebitis was identified in 12.5% of cases (3 out of 24 patients).
- While not associated with severe or progressive MS, one patient experienced unilateral vision loss (amaurosis) due to this condition. Immunosuppressive therapy showed efficacy in one instance.
Impact:
- The findings suggest a potential vascular mechanism in the pathogenesis of multiple sclerosis, especially given the absence of myelin in the retina.
- This study highlights the importance of ophthalmological examination in multiple sclerosis patients to detect potential complications like retinal periphlebitis.
- Early detection and management of retinal periphlebitis may help prevent severe visual impairment in multiple sclerosis patients.
