“…Recent evidence revealed that papilloedema is caused interruptions in the optic nerve (ON) metabolism as a result of the high intracranial pressure transmitted to the subarachnoid space surrounded the ON, leading to edema, ischemia, and eventual visual impairment or loss.14 Choroidal folds arise from globe compression from the distended optic nerve sheath leading to globe distortion and acquired hyperopic shift [15][16][17][18][19][20][21]. In our case, the patient reported no changes in his refractive errors compared to his pre-morbid state.…”

The typical presenting ocular signs of idiopathic intracranial hypertension (IIH) include bilateral papilledema, enlarged blind spots, and abducens nerve palsy. Unilateral papilledema with choroid folds is an atypical presenting sign of IIH. The authors report the case of a 55-year-old Chinese gentleman, of medium-built, presenting with right eye transient visual obscuration associated with tinnitus for 2 weeks. Physical examination revealed ipsilateral choroidal folds and disc swelling. Computerized tomography of the brain and orbit with contrast revealed no intracranial space occupying lesions. Lumber puncture revealed an elevated opening cerebrospinal fluid pressure (30 cm H ₂ O) with normal biochemistry. Subsequent contrast Magnetic Resonance Imaging of the brain and orbit with venogram revealed features of empty sella, compatible with the diagnosis of IIH. He was subsequently treated with oral acetazolamide for 6 months and the symptoms resolved. Unilateral papilloedema with choroidal folds is an uncommon presentation of IIH, a lumbar puncture with opening pressure measurement and proper neuro-imaging should be considered when there is suspicion of IIH.

“…von Winning6 theorized that the pattern of light and dark bands shown by fluorescein angiography may be explained by differences in RPE density. This theory is consistent with the finding that the banding patterns were inverted between fluorescein angiographic and autofluorescence images: rarefied RPE cells at the peak of a chorioretinal fold are dark on autofluorescence images from sparse lipofuscin but bright on angiograms due to a relative window defect.…”
