The purpose of this case report is to describe the obstruction of cilioretinal artery in a patient with acute focal retinitis occurring due to Chikungunya virus (CHIKV) fever.
A 45-year-old female presented with sudden and unilateral visual impairment from 2 days, which was preceded by a flu-like syndrome 2 weeks before. Multimodal imaging revealed focal retinitis in both eyes, which was complicated by cilioretinal artery obstruction in the left eye. Laboratory examinations confirmed the diagnosis of CHIKV fever and showed positive results (anti-CHIKV IgM and reverse transcriptase-polymerase chain reaction). The patient was treated with oral steroids. Following which, the patient showed a limited visual and anatomical recovery in the affected eye.
CHIKV fever has been currently associated with atypical manifestations. This indexed report describes a unique perspective on CHIKV focal retinitis, complicated by cilioretinal artery obstruction, further leading to limited visual recovery.
