Case Report of Post-typhoid Neuroretinitis: A Rare Cause of Visual Morbidity
Abstract
Post-typhoid fever neuroretinitis is a rare presentation, which is not well recognized and established. A 55-year-old female, previously admitted for typhoid fever, presented with a sudden onset, painless blurring of vision of the left eye. Visual acuity was logMAR 0.0 OD and logMAR 2 OS. Grade 1 relative afferent pupillary defect with dyschromatopsia was noted on the left eye. Fundus examination of the left eye revealed disc edema and a macular star exudate. Areas of retinitis at the peripapillary area and distal third of the supero-temporal arcade were noted. Patient was given prednisolone (1mg/kg/day) and was gradually tapered for 8 weeks with regular monitoring. At 6 months follow-up, vision of the left eye improved to logMAR 0.3. Fundus exam revealed moderate resolution of disc edema with residual exudates at the macula, and retinitis at the distal third of the supero-temporal arcade. Post-typhoid neuroretinitis presents as a significant cause of visual impairment. Due to its rarity, immediate diagnosis and treatment are frequently delayed. A high index of suspicion is prudent for prompt intervention and better visual outcome.
