BACKGROUND Cataract is one of the most common surgical procedures in the elderly. In most cases, the elderly have cardiac ischemia or chronic coronary diseases, which would lead to more ischemic events during general anesthesia. Therefore, surgeons and anesthetists prefer regional aesthesia to the general one owing to its more advantages and less complications. OBJECTIVES Therefore, this stud...

background: because general anesthesia is not a good choice in elderly asa>ii patients candidate for cataract surgery performored by ophthalmology residents and lack of cooperation in these patients, sedative effect and hemodynamic status and side effects of two drugs, remifentanil & propofol  are compared.   methods : in a randomized clinical trial on 60 patients candidate for cataract surgery...

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...

BACKGROUND/AIM It is known that glaucoma is associated with elevated intraocular pressure and obesity, yet the precise etiology remains unclear. The aim of this study was to determine whether there is a potential causality between the volume of retrobulbar adipose tissue and the level of intraocular pressure in obese subjects compared with non-obese. METHODS A total of 100 subjects were divid...

he practice of anesthesia has long been surrounded with a egree of mystique. This can be illustrated by the current ack of full-proof evidence on the mechanism of action of olatile anesthetics for example, which is for the most part ypothesized.1 These blurred margins of knowledge crossver into non-anesthesiologist practitioners using anesthetic echniques, sometimes, without fully grasping the ...

OBJECTIVE Ocular ischemic syndrome is a rare blinding condition generally caused by disease of the carotid artery. We describe a 69-year-old female with a 50 pack-year smoking history with aortic arch syndrome causing bilateral ocular ischemic syndrome. METHODS The patient presented with progressive visual loss and temple pain. Slit lamp biomicroscopy revealed bilateral iris neovascularizatio...
