CENTRAL RETINAL ARTERY OCCLUSION WITH CILIORETINAL ARTERY SPARING AFTER LASER-ASSISTED IN SITU KERATOMILEUSIS.

PURPOSE

To report a central retinal artery occlusion with cilioretinal artery sparing in a 48-year-old woman after laser-assisted in situ keratomileusis surgery.

METHODS

Case history and clinical examination including best-corrected visual acuity, serum markers, slit-lamp biomicroscopy, indirect ophthalmoscopy, fundus photography, fluorescein angiography, and optical coherence tomography.

RESULTS

A 48-year-old woman underwent routine laser-assisted in situ keratomileusis surgery in both eyes. On postoperative Day 1, vision was 20/20 in both eyes with full visual fields by confrontation. Eight hours after being examined, she reported photopsias and a new visual field defect in the right eye . Visual acuity was 20/40, pinhole 20/20 in the right eye, with restriction of visual field by confrontation. Dilated fundus examination revealed retinal whitening in all quadrants with sparing of the fovea along the distribution of a perfused cilioretinal artery. Optical coherence tomography showed an intact foveal depression with inner retinal layer hyperreflectivity outside the region of the perfused cilioretinal artery. Fluorescein angiography revealed sectoral nonperfusion of the posterior pole with macular sparing along the patent cilioretinal artery. Hypercoagulable workup, carotid imaging, and magnetic resonance imaging of the brain were unremarkable.

CONCLUSION

This is the first report of a central retinal artery occlusion with cilioretinal artery sparing occurring on postoperative Day 1 after laser-assisted in situ keratomileusis surgery.
