Ewing's sarcoma is a relatively common malignant bone tumor that typically occurs in long bone diaphyses of adolescents and young adults of 10-30 years old. Often times, all Ewing's sarcoma of bone have radiographic abnormalities. Diagnosis is usually delayed and can be misdiagnosed as osteomyelitis. Bone to bone metastasis occurs, but soft tissue retro bulbar metastas...

BACKGROUND Retrobulbar neuritis in Herpes Zoster Ophthalmicus (HZO) has been reported very rarely. OBJECTIVE To report a very rare case of HZO with retrobulbar neuritis with detailed clinical features and treatment responses. CASE A fifty-eight- year old male presented with Herpes zoster-retrobulbarneuritis in the left eye. It was characterized by decreased visual acuity, mid dilated pupil ...

BACKGROUND AND PURPOSE This study was to evaluate the retrobulbar hemodynamics in patients who have transient monocular blindness (TMB) without carotid stenosis. METHODS Fifty-nine patients who have TMB without carotid stenosis were studied along with 59 age- and sex-matched controls. Color Doppler-imaging was used to study the retrobulbar hemodynamic by measuring the flow velocities (peak-sy...

Recent improvements in technique have made cataract surgery a popular procedure in the outpatient setting. One of those advances has been the use of retrobulbar block instead of general anesthesia. This article explains the anatomy, pharmacology, technique and complications of retrobulbar block.

Background: The injection of retrobulbar block is associated with significant pain and discomfort. Therefore a short-acting IV analgesic before retrobulbar injection has been advocated. Objective: To compare remifentanil, alfentanil and fentanyl in providing analgesia for retrobulbar block injection. Methods: 69 patients were enrolled randomly into three groups of 23 each to receive either Remi...

purpose : to report a case of total blindness a few hours after orbital blowout fracture repair the visual acuity (va) returned to normal after immediate reoperation. case report : a 21-year-old man with obvious enophthalmos in the left side, 2 weeks after car accident, was candidate for orbital floor reconstruction surgery. anterior orbitotomy from subcilliary incision was done and at the end ...

Peribulbar anaesthesia has been recommended as a safer alternative to retrobulbar anaesthesia. We report a case of perforation of the globe sustained during peribulbar anaesthesia which resulted in blindness. Orbital injections are potentially dangerous, be they peribulbar or retrobulbar. To minimise the risk, short, blunt needles are advocated for the peribulbar route.

OBJECTIVE To compare the effects of fentanyl or remifentanil in combination with midazolam on hemodynamic parameters, pain, and satisfaction profile in cataract surgery. METHODS This randomized, double blind, prospective study was conducted between 10 and 20th July 2005 at Kudret Eye Hospital, Ankara, Turkey. Patients scheduled for cataract surgery by the phacoemulsification technique were ra...
