PURPOSE: To report a case of cilioretinal artery occlusion with normal fluorescein angiography findings that was evaluated by electroretinography (ERG) and microperimetry.
METHODS: A 64-year-old-man presented with an oval paracentral scotoma in the temporal field of the left eye that became more evident after cataract surgery. Fundus photography, fluorescein angiography, ERG, multifocal ERG, and microperimetry were performed.
RESULTS: Multifocal ERG showed decreased signal amplitudes in areas corresponding to areas with a visual defect as detected by microperimetry. Pattern ERG also showed a defect in the P50 component. Findings of fundus photography, fluorescein angiography, and full-field ERG were within normal limits.
CONCLUSION: This case demonstrates the possibility of using ERG and microperimetry as noninvasive tools in the diagnosis of cilioretinal artery occlusion.
