BACKGROUND: Electrical potentials generated in the central nervous system in response to brief visual stimuli, flash visual evoked potentials (FVEPs), can be recorded non-invasively over the occipital cortex. FVEPs are used clinically in human medicine and also experimentally in a number of animal species, but the method has not yet been evaluated in the horse. The method would potentially allow the ophthalmologist and equine clinician to evaluate visual impairment caused by disorders affecting post-retinal visual pathways...

Eye lesions are commonly observed in pinnipeds. Clinical assessment is challenging because animals are often blepharospastic and under inhalant anesthesia the globe rotates ventrally, making observation difficult. Retrobulbar and auriculopalpebral nerve block techniques have been developed in other species to alleviate these difficulties and allow for a more thorough ophthalmic exam. Ocular nerve block techniques were developed for California sea lions (CSLs) (Zalophus californianus) using lidocaine hydrochloride 2%...

BACKGROUND AND OBJECTIVES: management of pain in painful blind eyes is still a challenge. Corticosteroids and hypotensive agents, as well as evisceration and enucleation, are some of the strategies employed so far that are not always effective and, depending on the strategy, cause a deep emotional shock to the patient. Given these issues, the aim of this case report is to demonstrate a new and viable option for the management of such pain by treating the painful blind eye with the stellate ganglion block technique, a procedure that has never been described in the literature for this purpose...

The authors' 15-year experience with migraine surgery has led them to believe that the most common reasons for incomplete response are failure to detect all of the trigger sites or, on rare occasions, inadequate surgery on the trigger sites. Thus, accurate identification of trigger sites is essential. The purpose of this article is to share the authors' current stepwise algorithm for accurately detecting the migraine trigger sites, which has evolved through surgery on nearly 1000 patients. To begin, a thorough history is taken...

In the past decade ophthalmic anesthesia has witnessed a major transformation. The sun has set on the landscape of ophthalmic procedures performed under general anesthesia at in-hospital settings. In its place a new dawn has ushered in the panorama of eye surgeries conducted under regional and topical anesthesia at specialty eye care centers. The impact of the burgeoning geriatric population is that an increasing number of elderly patients will present for eye surgery. In order to accommodate increased patient volumes and simultaneously satisfy administrative initiatives directed at economic frugality, administrators will seek assistance from anesthesia providers in adopting measures that enhance operating room efficiency...

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 Caucasian healthy male with a right eye retinal detachment was admitted for pars plana vitrectomy...

BACKGROUND: Cataract is a major cause of blindness worldwide. Unless medically contraindicated, cataract surgery is usually performed under local (regional) anaesthesia. Local anaesthesia involves the blockage of a nerve subserving a given part of the body. It involves infiltration of the area around the nerve with local anaesthetic. The two main approaches in the eye are retrobulbar and peribulbar. There is debate over whether the peribulbar approach provides more effective, safer anaesthesia for cataract surgery than retrobulbar block...

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 cyclodestructive procedures, retrobulbar injection of absolute alcohol and evisceration or enucleation. A case series of 5 patients of absolute glaucoma who were successfully treated with retrobulbar alcohol injection is reported...

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 study aimed to compare topical method and retrobulbar block for pain intensity, patient's satisfaction, hemodynamic changes and intra and postoperative complications...

BACKGROUND: Retrobulbar anaesthesia is a valuable alternative not only for polymorbid and haemodynamically compromised patients. Complications are rare but may be devastating. METHODS: Principally, any intraocular surgery can be made under local anaesthesia. There are only a few contraindications to regional anaesthesia such as denial against regional anaesthesia, allergy to local anaesthetics, local infection, severe orthopnea, insufficiently controlled psychiatric disorders or small children and non-cooperative patients...
