his medical record did not show any atherosclerotic vascular disease. Physical examination at admission did not reveal any bruits over either of the carotid arteries. No neurological deficits were detected. His blood pressure was 125/82 mm Hg, and his pulse rate was 72 beats/min and regular. Coagulation parameters, including antithrombin III, proDear Sir, Transient monocular blindness (TMB) or ...

BACKGROUND Embozene® is a new neuroembolizing microsphere used to reduce intraoperative bleeding for head and neck tumours. We report a case of iatrogenic ophthalmic artery occlusion after Embozene® embolization of the external carotid artery (ECA). CASE PRESENTATION A 22-year-old African gentleman presented with left nasal obstruction and epistaxis for 2 years and was diagnosed with nasophar...

When internal carotid artery stenosis is accompanied by ocular ischemic syndrome, intervention is recommended to prevent irreversible visual loss. In this study, we used laser speckle flowgraphy to measure the ocular microcirculation in the optic nerve head before and after carotid artery stenting (CAS) of 40 advanced internal carotid stenosis lesions from 37 patients. The aim was to investigat...

BACKGROUND Central retinal artery occlusion (CRAO) is the occlusion of the central retinal artery resulting in retinal infarction and acute vision loss. Digital subtraction angiography (DSA)-guided superselective ophthalmic artery or selective carotid thrombolysis remains the preferred treatment method for CRAO. This study aimed to evaluate the safety and clinical efficacy of the novel ophthalm...

Retinoblastoma is one of the most common ophthalmic neoplasms affecting children worldwide. Since its recent introduction, superselective ophthalmic artery injection of chemotherapy with melphalan has significantly reduced the need for enucleation in patients with advanced disease and also shown to have minimal adverse effects on visual acuity as compared to the conventional therapy. Although n...

Superselective ophthalmic artery injection of the chemotherapeutic agent is a new treatment option for advanced retinoblastoma.[1] We present case severe bronchospasm with loss tidal volume and oxygen desaturation in an infant during catheterization under general anesthesia.

PURPOSE The aim of this study was to examine whether the retinal circulation in the pig can be accessed using interventional neuroradiology and to explore the possibility of creating occlusions that result in experimental retinal ischemia. METHODS Six experiments were performed using 100-kg pigs. The external carotid system was catheterized using a fluoroscopy-monitored, transfemoral, endovas...

purpose: to assess orbital color doppler ultrasonography (cdu) parameters of patients with manifest hyperopia in comparison to the emmetropes methods: forty eyes of 40 patients presenting with manifest hyperopia were included into the study. forty eyes of 40 emmetropes healthy volunteers also were examined as the control group. we have evaluated ophthalmic artery (oa), central retinal artery (c...

The influence of multiple systemic factors upon the blood velocities obtained from the orbital circulations was investigated. The velocities obtained by colour Doppler imaging from the ophthalmic artery, central retinal artery, and vein from 95 ophthalmologically healthy volunteers were analyzed. The effects of age, systemic blood pressure, and smoking habit were examined. In 24 volunteers bloo...

OBJECTIVE To describe treatment complications following intra-arterial chemotherapy (IAC) for retinoblastoma. METHODS A retrospective interventional series of ophthalmic artery cannulation for IAC injection (3 planned sessions at 1-month intervals) was undertaken. Thirty-eight catheterizations of 17 eyes of 17 patients were performed from September 2008 to September 2010. Fluoroscopy of the o...
