PARACENTRAL ACUTE MIDDLE MACULOPATHY AFTER AORTIC ANEURYSM REPAIR.

PURPOSE: We report a case of paracentral acute middle maculopathy secondary to cholesterol embolization syndrome after an endovascular aortic aneurism repair (EVAR).

METHODS

Functional and anatomical damage was assessed by Snellen visual acuity, fundoscopy, and optical coherence tomography.

RESULTS

A 67-year-old man presented with sudden vision loss in the right eye for one day with concomitant livedo reticularis in both feet. His medical history included an abdominal EVAR repair three days before the symptoms. The best-corrected visual acuity was 20/40 in the right eye and 20/20 in the left eye. Fundoscopy showed intraarteriolar cholesterol plaques (Hollenhorst) bilaterally, and a localized retinal whitening in the right eye. Optical coherence tomography at the lesion site revealed a hyperreflective band on the level of inner nuclear layer. The patient was referred for imaging and complete systemic evaluation. He was then closely followed up by a vascular team, without additional intervention. Retinal stigma partially regressed at six months with visual improvement.

CONCLUSION

This case describes paracentral acute middle maculopathy as a rare ocular sign of cholesterol embolization in postoperative intraaortic operations. The diagnosis of this complication led to prompt clinical care with a multidisciplinary approach.
