VISUAL-FIELD LOSS CAUSED BY RETINAL VASCULAR OCCLUSION AFTER VITRECTOMY SURGERY

PURPOSE: To report complete superonasal retinal arterial occlusion wit h resulting temporal visual field loss after uneventful pars plana vit rectomy with gas fluid exchange. METHOD: Case report. RESULTS: Superon asal retinal arterial occlusion was observed 12 days after vitrectomy surgery, Within 10 weeks, the artery reperfused, leaving minimal vascu lar attenuation and mild optic atrophy. CONCLUSIONS: Uneventful vitrec tomy surgery can be associated with notable peripheral visual field lo ss caused by arterial occlusion in the immediate postoperative period, Rapid resorption of the intraocular gas and timely postoperative exam ination may disclose retinal arteriolar occlusion; otherwise, subseque nt reperfusion may leave little evidence of the vascular event.
