Abstract
Title: A case of central retina artery occlusion secondary to failed cerebral coiling due to Barrow type D carotid cavernous fistula (CCF).
Background: To report a case of central retina artery occlusion after failed coiling in a Barrow Type D CCCF
Method: Case report
Result: A sixty-four-year-old male with no prior history of trauma, presented with insidious onset of right eye proptosis with corkscrew vessels and bruit with increased intraocular pressure (IOP) but no blurring of vision and normal retina. Radiological examination showed Type D CCF. Cerebral coiling was performed but failed and resulted in worsening vision and intraocular pressure and noted to have central retina artery occlusion (CRAO). Secondary embolization was performed which obliterated the fistula, in which the patient recovered favorable visual function.
Conclusion: CRAO is a rare complication of cerebral coiling, in which the patient regained favorable visual function. This report describes our experience of CRAO post cerebral coiling which recovered after obliteration of the fistula by embolization.
