To describe swept-source optical coherence tomography angiography (SS OCT-A) findings in a patient with unilateral acute idiopathic maculopathy.
Department of Ophthalmology, Fattouma Bourguiba University Hospital, Faculty of Medicine, University of Monastir, Monastir, Tunisia.
A single case report.
A 48 year-old otherwise healthy male was referred to our department for blurred vision in the right eye (RE) for 1 month. The best corrected visual acuity was 20/1000 in the RE and 20/20 in the left eye. There were no cells in the anterior chamber and in the vitreous. Fundus examination revealed a yellowish macular well-defined lesion in the RE. Fluorescein angiography revealed multifocal areas of choroidal filling delay. The macular lesion was hypofluorescent in the early phase, with staining in the late phase. This lesion was hypofluorescent on indocyanine green angiography. Optical coherence tomography showed disruption and irregularity of the outer photoreceptor layer. Multimodal imaging results were consistent with the diagnosis of unilateral acute idiopathic maculopathy in the RE. Serology for Coxsackie virus was positive. SS OCT-A, a month after onset of symptoms, showed a central area of reduced flow within the choriocapillaris. Six months later, visual acuity and SS OCT-A findings in the RE remained the same.
Unilateral acute idiopathic maculopathy is a rare cause of unilateral, sudden, painless vision loss in healthy adults. SS OCT-A shows evidence of choroidal ischaemia in this condition.
