Ocular pain can be multi-factorial and often refractory to treatment, in spite of the myriad options available to the ophthalmologist for its management. Initial therapy entails the use of topical and systemic pressure lowering agents as well as anti-inflammatory/analgesics for the provision of relief. Those refractory to medical therapy may require surgical intervention in the form of cyclodes...

We present the MR imaging findings in a 43-year-old male patient with bilateral idiopathic sclerosing inflammation of the orbit. Bilateral enhancing retrobulbar masses, with concentric compression of the retrobulbar segment of the left optic nerve, were seen. MR imaging proved to be the only means to distinguish between the different intraorbital structures and to determine the exact site of op...

We report a long-term eye movement study of a 68-year-old female with pontomedullary junction cavernous malformation whose dysconjugate nystagmus was treated with retrobulbar botulinum toxin A injections. Sequential, bilateral retrobulbar injections of botulinum toxin A were performed. Injections immediately decreased oscillopsia and nystagmus, and improved visual acuities. One to three months ...

Extracapsular cataract extraction with lens implant under local anaesthesia consisting of amethocaine drops followed by a simple subconjunctival injection in the upper part of the globe but without a retrobulbar injection was carried out in 175 eyes of 165 patients. The purpose of the study was to establish the feasibility of this type of anaesthesia in cataract surgery with the principal objec...

n engl j med 369;11 nejm.org september 12, 2013 1080 anticoagulants may prevent warfarin-induced skin necrosis but cannot be recommended yet. Finally, in reply to Grzybowski and Ascaso: the use of antithrombotic agents in ocular surgery remains highly controversial. The stated bleeding rate of 3% is excessive in modern cataract surgery. This avascular procedure, which is frequently performed wi...

Twelve thousand regional anaesthetics for cataract extraction and intraocular lens implantation surgery were administered by one anaesthetist over a period of 52 months in a free-standing outpatient surgical facility. The ophthalmologist, who did all the operations, assessed the quality of the blocks using an objective scoring system which is described. The first 3,595 patients had retrobulbar ...

Ten patients undergoing cataract surgery were given a local anaesthetic with lignocaine solution which was mixed with iohexol contrast medium. The location of the needle and the substance injected was determined by computerised tomography following retrobulbar or periocular anaesthesia. The retrobulbarly inserted needles were within the muscle cone, directed towards the optic foramen. The perio...

OBJECTIVE To compare the efficacy and efficiency of retrobulbar versus sub-Tenon's capsule injection of local anesthetic in vitreoretinal surgery. DESIGN Prospective, randomized, double-masked clinical trial. PARTICIPANTS AND INTERVENTION Sixty-four eyes from 61 patients undergoing vitreoretinal surgery were randomized to receive either retrobulbar or sub-Tenon's capsule injection of 5 ml o...

Posterior vitreous fluorophotometry measurements have been shown to be increased in patients with acute retrobulbar neuritis. We studied 12 patients who had optic neuropathy by posterior vitreous fluorophotometry, with and without correction for blood fluorescein concentration. Both uncorrected and corrected posterior vitreous measurements were increased in patients with inflammatory, obstructi...
