PURPOSE Topical anesthesia is increasingly being used for cataract surgery. However, it is believed that topical anesthesia causes an increased risk of intraoperative complications from unrestricted eye movement and insufficient pain control and more need for sedation. It is difficult to compare pain and anxiety experienced by individual patients; therefore, the authors used the method of patie...

The studybySoares et al. 1 published in this edition of the Brazilian Journal of Anesthesiology has aroused old questions about anesthetic techniques for eye surgery: retrobulbar, peribulbar, extraconal, periconal and subtenonian Anesthetic techniques aim at depositing local anesthetics in a given point as from which spread may reach ciliary nerves responsible for eye sensitivity, ciliary gangl...

abstract background and aim: consider ing based on the presence or absence of swelling of the optic disc, optic neuritis classified nto two types of anterior and retrobulbar optic neuritis. the aim of this study was to compare the visual functions of patients with anterior optic neuritis and retrobulbar optic neuritis. materials and methods:this cross-sectional study was conducted in 48 patient...

BACKGROUND Retrobulbar block is a local anesthetic technique widely used for intraocular surgery. Although retrobulbar anesthesia is considered to be relatively safe, a number of serious adverse events have been reported. To our knowledge, immediate onset of generalized seizures with contralateral hemiparesis after retrobulbar anesthesia has not been reported. CASE PRESENTATION A 62-year-old ...

PURPOSE To present clinical features of central retinal artery occlusion (CRAO) following retrobulbar anesthesia for intraocular surgery. METHODS This observational case series describes 5 consecutive patients with acute CRAO following retrobulbar anesthesia for intraocular surgery. Data collected for this study included subject characteristics, retrobulbar anesthesia technique, treatment typ...

INTRODUCTION Acute retrobulbar haemorrhage is a potentially sight-threatening condition, and can follow retrobulbar anaesthesia or trauma to the orbit. Acute loss of vision can occur with retrobulbar haemorrhage and is reversible if the condition is recognised and treated early. CLINICAL PICTURE We report a case of acute retrobulbar haemorrhage following orbital trauma in a 78-year-old Chines...

PURPOSE To determine whether recombinant human interferon alpha-2a (IFN alpha-2a) would diffuse into the choroid in significant amounts from a retrobulbar depot. METHODS One million international units of IFN alpha-2a were injected into the retrobulbar space of the eyes of 17 rabbits, and choroidal and serum concentrations were measured at 1, 2, 4, 8, 12, and 24 hours. The same dose of IFN al...

Fluorescein fundus photography is of value in the detection of early papilloedema (David, Heyman, and Hart, 1963; Miller, Saunders, and Ffytche, 1965). We have applied this technique to the serial study of patients with acute retrobulbar neuritis. This disorder is usually unilateral and the unaffected eye could be used as a control. Also, since papilloedema is not present at the onset of sympto...

The aim of this paper is to compare diameter of healthy and affected optic nerve determined by ultrasound with brain lesions in acute retrobulbar neuritis in patients with multiple sclerosis. In this prospective study 20 patients with multiple sclerosis and acute retrobulbar neuritis were examined. Optic nerve diameter was measured by ultrasound. Brain lesions were detected by magnetic resonanc...
