Early Bilateral Cystoid Macular Oedema Secondary to Fingolimod in Multiple Sclerosis

الملخص EN

We report a case of fingolimod-associated bilateral cystoid macular oedema in a patient with multiple sclerosis (MS).

A 34-year-old female, diagnosed with MS at age of 30, developed bilateral blurred vision 5 days after initiation of fingolimod.

She was misdiagnosed as optic neuritis initially and fingolimod was only discontinued 3 weeks after onset of her visual symptoms when OCT showed prominent bilateral cystoid macular oedema and subretinal fluid.

Although her left corrected vision returned to 6/6, she had persistently decreased right visual acuity of 6/12 after 5 months.

This paper aims to raise awareness among ophthalmologists and neurologists of the importance of early recognition of macular oedema associated with fingolimod.
