[Temporal crescent syndrome. Report of a case and review of the literature].
The temporal crescent syndrome or half-moon syndrome is a rare mono ocular retrochiasmatic visual field defect that can be correlated to a lesion along the contralateral parieto-occipital sulcus. This field defect may be missed in automated perimetry. We report a 45 year old man, consulting for sudden loss of the peripheral temporal field in his right eye. The magnetic resonance imaging and the spectroscopy studies confirmed an ischemic lesion on the left anterior occipital cortex. Control imaging studies six months later did not show changes in the lesion.
