Bilateral Optic Neuritis in a Patient with Enteric Fever: A Case Report.

BACKGROUND

Bilateral optic neuritis following enteric fever is a rare condition requiring early evaluation by an ophthalmologist and prompt treatment for visual rehabilitation.

CASE: A 31-year-old female diagnosed with enteric fever presented to the Neuro-ophthalmology department with sudden painful loss of vision in both eyes for 10 days.

OBSERVATIONS: Her Best Corrected Visual Acuity (BCVA) was counting fingers close to face in left eye and 6/18 in right eye. Posterior segment examination showed blurring of disc margin on both eyes. On Magnetic Resonance Imaging (MRI) of brain and orbit there was mild thickening of retro-orbital portions of both optic nerves. She was started on steroid therapy which resulted in marked improvement of vision in both eyes.

CONCLUSION

Optic neuritis following enteric fever is a rare entity and requires early diagnosis with prompt treatment for improvement of visual acuity and prevention of visual impairment.
