[Periphlebitis retinae, uveitis and cystoid maculopathy in a patient with multiple sclerosis]

A 44-year-old woman has a history of multiple sclerosis since 20 years. Besides recurrent numbness she had many instances of optic nerve neuritis which has led to a pronounced optic atrophy on her left eye. Additionally, she has developed recurrent iridocyclitis on her right eye. This was the reason why she was referred to our outpatient department for evaluation. Ophthalmic examination revealed an iridocyclitis associated with a multifocal retinal periphlebitis and severe cystoid macular edema in her right eye.

Patients with multiple sclerosis develop in approximately 30% of cases retinal periphlebitis which may rarely be associated with anterior uveitis or cystoid macular edema as observed in our patient.
