Filter by:The present tiral conduted to demonstrate the administration of sugammadex as reversal of neuromuscular blockade agent reduces the incedence of emergence agitation (EA) comparing to neostigmine
The hypothesis of this study is that providing continuous binaural beats with a phase difference in alpha frequency during anesthesia can reduce the incidence of emergence agitation in pediatric patients. To test this hypothesis, the occurrence of emergence agitation will be compared between the group that received binaural beats and the group that did not receive binaural beats.
The purpose of this study is to determine if inducing a moderate or greater neuromuscular block (TOF count 0-3) when performing a neuromuscular block in pediatric patients aged 3 to 18 years undergoing strabismus surgery under general anesthesia can reduce the incidence of the oculocardiac reflex.
The aim of this interventional, cross-sectional study is to evaluate the performance and the safety of the medical device software S360. This clinical investigation is performed in order to demonstrate the conformity of the medical device, when operating under the normal conditions of its intended use, in accordance with the General Safety and Performance Requirements pertaining to clinical evaluation of the device regarding the Medical Device Regulation (MDR) 2017/745 (EU).
The purpose of this study is to evaluate supramaximal rectus recession for strabismus in Grave's Ophthalmopathy
The purpose of this study is to determine whether combination of orbital compression surgery with strabismus surgery is better than strabismus surgery after orbital compression surgery in the treatment of moderate-to-severe thyroid associated ophthalmopathy
This study aimed to assess the effectiveness of the Subconjunctival bupivacaine on postoperative pain in Strabismus surgery under general anaesthesia.
In this study, the surgical outcomes of lateral rectus plication and resection techniques on patients with residual esotropia will be compared. Methods: In this randomized clinical trial, a total of 57 patients with residual esotropia (31 females and 26 males) who were candidate for lateral rectus resection are going to be included and randomized into plication and resection groups. The inclusion criteria will be residual esotropia after uni- or bilateral medial rectus recession, or unilateral recession and resection (R&R). Subjects with a history of prematurity, lack of central fixation, extraocular muscle palsy, systemic, ocular disorders, follow up less than three months will be excluded. A comprehensive ophthalmic examinations are going to be conducted preoperatively and at 1, 3 and 6 months' follow-ups. Surgical success rate will be considered in cases with a postoperative eso- or exotropia ≤10pd.
Horizontal strabismus includes esotropia and exotropia where there is inward or outward deviation of visual axes of the eyes respectively. The most common initial treatment of horizontal strabismus is either bilateral rectus muscle recessions or unilateral recession resection surgery. For large angle deviations (>50 prism diopters [PD]), surgery on 2 muscles alone may not be adequate with high reoperation rates. Approaches to these patients included large bilateral muscle recessions, supramaximal unilateral recession resection procedure, three or four horizontal muscle surgery, or botulinum toxin augmented surgery. Botulinum toxin augmentated strabismus surgery was reported in several studies. Owens et al.reported successful botulinum toxin augmentation of monocular recession-resection surgeries in 3 large-angle exotropia patients with successful results in two of the 3 patients. Khan reported 8 patients with > 60 PD esotropia treated with botulinum-augmented surgery. Six of 8 had deviations of 10 PD or less following surgery. Özkan et al used botulinum augmentation in a group of older patients with large angle esotropia of different etiologies, with a success rate of 57%. Lueder et al evaluated the long-term outcomes in patients with infantile esotropia. The results were good, with a 74% success rate. Based on historical comparisons, this technique appears equally as effective as 3- or 4-muscle surgery and more effective than large bilateral medial rectus recessions alone. Ideally, a prospective randomized study should be performed to more definitively determine the effectiveness of intraoperative botulinum toxin augmentation compared to surgery alone.
Around one child in fifty has a lazy eye (termed amblyopia) where the eye is structurally normal but the vision fails to develop correctly. Around half of these children also have a squint (strabismus) where each eye has a different direction of gaze. This condition is the commonest cause of visual impairment in one eye in children. This is a randomised control trial of wearing glasses alone (which will result in some visual improvement, termed refractive adaptation) and wearing glasses combined with using I-BiT Plus. The hypothesis is that using I-BiT Plus will result in an improved visual outcome.
