“…An experimental study of central retinal artery occlusion showed that occlusion lasting about 97 min resulted in massive, irreversible damage. Thus, no treatment instituted much longer than 1.5 hours after the onset can be expected to restore vision [19-21]. …”

BackgroundCardiac catheterization may cause retinal embolization, a risk factor for cerebrovascular emboli and stroke. We describe the incidence of clinically silent and apparent retinal emboli following diagnostic and interventional coronary catheterization and associated risk factors.MethodsThree hundred selected patients attending a tertiary referral center for diagnostic and therapeutic cardiac catheterization were studied. Retinal examination and examination of the visual field and acuity were done before and after catheterization by a retinal specialist.ResultsThere were 5 case of retinal embolus before catheterization, and 19 patients (incidence 6.3%) developed new retinal arteriolar emboli after catheterization. Only 1 patient developed clinically apparent changes in vision. Two conventional risk factors (age and hypertension) were significantly associated with new retinal emboli. The risk of retinal emboli was also significantly associated with operator expertise.ConclusionsRetinal embolism was found after coronary catheterization in 6.3% of our patients. This finding indicates that the retinal, and possibly the cerebral circulation, may be compromised more frequently than is clinically apparent as a complication of coronary catheterization. Age and hypertension are independent predictors of retinal embolism.Trial RegistrationNCT01157338

“…The causes of CRAO include embolism, thrombosis, vasculitis, arterial spasm, arterial dissection, and hypertensive arteriolar necrosis [3]. Of these, embolism is by far the most common cause, and the major source of emboli is a plaque in the carotid artery [10].…”

“…For example, less than one hundred cases of stroke from chiropractic manipulation have been reported since 1925 [1,2]. Five cases of central retinal artery occlusion following cardiac catheterization [3,4] and one case of central retinal artery occlusion after chiropractic manipulation on the neck have also been described [1]. Here we describe a patient with central retinal artery occlusion following chiropractic manipulation, which has not previously been reported in Korea.…”

Here we report a case of central retinal artery occlusion after chiropractic manipulation on the neck. A 49-year old man presented at the hospital because of sudden visual loss in his right eye after chiropractic neck manipulation. He had received chiropractic manipulation of the neck by a chiropractor eight days prior. When he first visited us, his best corrected visual acuity in his right eye was hand motion. A full ophthalmic examination was performed. There was cherry-red spot in the macula in his right eye. We performed a fluorescein angiogram and cervical color Doppler. The arterio-venous transit time in the fluorescein angiogram was delayed, and we detected stenosis of the right internal carotid artery with diffuse atherosclerotic plaques in the right common carotid artery. We prescribed ginko biloba extract (Tanamin). Three years after his first visit, the best corrected visual acuity of his right eye was 20 / 200.

Aim of the study: To find the incidence of new ocular symptoms following transradial diagnostic and therapeutic coronary catheterization and associated risk factors. Materials & Methods: Prospective observational study of 500 consecutive patients satisfying the inclusion criteria attending our tertiary health centre for transradial coronary procedures were observed for post procedural new ocular symptoms and compared with 500 patients undergoing same via transfemoral approach. Results: 76 patients (incidence 7.6%) developed new ocular symptoms in the form of black-outs, Amaurosis fugax and field loss. 75% of these patients belonged to radial access group. 40 patients had reversible visual symptoms as a sequalae of cerebral hypo perfusion and 36 patients had symptoms of retinal embolism. Clinically apparent changes in vision was noted in 9 [0.9%] patients. In those with new ocular symptoms, the risk factors found were age, periprocedural hypertension, vascular tortuosity, procedure done through radial artery approach in patients with height<155cm ,prolonged procedural time. 1patient had uniocular Central Retinal Artery Occlusion [CRAO] with permanent loss of vision. 3 patients had features of Branch Retinal Artery Occlusion [BRAO] and 5 patients had peripheral retinal embolus.Conclusions: Although rare, incidence of ocular embolic complications were higher with percutaneous coronary procedures via radial approach. Patients with height <155 cm may be benefitted when the procedure is done via femoral approach. Cardiologists should try to avoid excessive catheter manipulations while doing procedures. Prompt diagnosis and treatment may reduce extent of damage caused by vascular embolism.
