We report the successful removal of a retrobulbar foreign body using a transcranial approach in a 63-year-old patient with a penetrating injury to the left eye. Initial ocular examination revealed a corneoscleral laceration, hyphema, a traumatic cataract, and vitreous hemorrhage. Visual acuity consisted only of the perception of hand motion. Computed tomography demonstrated an orbital foreign b...

PURPOSE To determine the effects of topical epinephrine and retrobulbar anesthesia containing lidocaine with epinephrine on retrobulbar hemodynamic measurements in the primate eye, using color Doppler ultrasound. METHODS Color Doppler ultrasound measurements were performed at baseline and 90 minutes after masked administration of topical 2% epinephrine or balanced salt solution to six cynomol...

A 53-year-old woman experienced a right retrobulbar pain followed by ipsilateral extraocular palsies in all directions without dilated pupils or ptosis. Because a plain head computed tomography (CT) scan obtained on her initial visit showed no abnormal findings, such as subarachnoid hemorrhage or a giant cavernous aneurysm, her condition was provisionally diagnosed as Tolosa-Hunt syndrome and e...

In endoscopic sinus surgery, the anterior ethmoidal artery (AEA) is usually identified as it traverses obliquely across the fovea ethmoidalis, posterior to the bulla ethmoidalis and anterior to or within the ground lamella's attachment to the skull base. Injury to the AEA may result in hemorrhage, retraction of the AEA into the orbit, and a retrobulbar hematoma. The resulting increase in intrao...

BACKGROUND/AIMS An acute immunological stress reaction was previously reported to occur after the painful setting of retrobulbar anaesthesia before intraocular surgery. This study was conducted to find out whether an oral low dose premedication with midazolam would modify the immunological stress reaction. METHODS 32 patients undergoing intraocular surgery using retrobulbar anaesthesia were i...

PURPOSE To compare the safety and efficacy of topical plus subconjunctival versus retrobulbar anesthesia for primary non-penetrating sclerectomy supplemented with adjuntive 5-FU. METHODS A prospective study of 30 consecutive patients who were randomized to receive subconjunctival (n = 14) or retrobulbar (n = 16) anesthesia was performed. Operating conditions, patient comfort, postoperative pa...

Purpose To describe a complication of retrobulbar amphotericin B injections in the treatment of invasive rhino-orbital asperigillosis. Observations 27 year-old renal transplant recipient presented with a two-week history of headache, binocular diplopia and proptosis of the left eye. Endonasal biopsy on hospital day 3 confirmed the diagnosis of rhino-orbital invasive Aspergillus fumigatus invo...

Retrobulbar neuritis is often very complicated clinical entity. The most common cause of retrobulbar neuritis is demyelinating disease of CNS. This report is to express some other uncommon causes of it. Three children, age 8 to 12 with sudden and severe visual loss are presented. The diagnosis of retrobulbar neuritis is made by complete ophtalmological examination in consultation with neuropedi...

OBJECTIVES To compare the effectiveness, in terms of pain relief and akinesia of retrobulbar and subconjunctival an aesthesia during cataract surgery and also to compare the degree of postoperative ptosis associated with each technique. MATERIALS AND METHODS Consecutive adult patients undergoing cataract surgery between March and June 2008 at the Guinness Eye Center Onitsha, were randomized i...
