Under-correction in Refractive Accommodative Esotropia

Accommodative Esotropia

In most clinics, physicians reduce diopter of hyperopic glasses in older patients with accommodative esotropia. However, there are risks of decompensation in that practice. The authors are going to try measure the change of stability of eye alignment after reducing diopter of hyperopic glasses.

Comparison of Two Treatments for Strabismus Correction: Botulinum Toxin A Associated to Surgery...

EsotropiaExotropia

Two different treatments were given to large angle horizontal strabismus (eso and exotropia) adult patients who agree to participate of the study. Inform consents were required for participants. Group 1 (12 patients) received conventional recess-resect surgery plus intraoperative injection of botulinum toxin A (5U). Group 2 (11 patients) received only conventional recess-resect surgery. The patients were randomly located in one of the groups. The angles of horizontal deviation were compared between the groups before and six months after treatment.

Povidone-iodine Antisepsis for Strabismus Surgery

StrabismusSurgery1 more

The purpose of this study is to compare the efficacy of 5 % vs. 1.25 % povidone-iodine (PI) as preoperative antiseptic prior to strabismus surgery in children as a prophylaxis of endophthalmitis. Given the low rate of endophthalmitis the conjunctival bacterial flora rate is used as surrogate marker to determine the effectiveness of topical PI in reducing or eliminating bacteria from the ocular surface at the time of the surgery. Secondary objective is a reduction of the incidence of postoperative endophthalmitis after strabismus surgery in young children.

Effects of Dexmedetomidine Premedication on Emergence Agitation After Strabismus Surgery in Children...

Inhalational Anesthetics Adverse ReactionDelirium on Emergence1 more

Sevoflurane is frequently used for pediatric anesthesia because it has low pungency and rapid onset and offset of action.The reported incidence of emergence agitation (EA) following sevoflurane anesthesia varies from 10-80%. Despite its spontaneous resolution, EA is still considered as a potentially serious complication because of the risks of self-injury, and because of the stress caused to both caregivers and families. Dexmedetomidine, an Alpha2-adrenoceptor agonist with sedative, analgesic, and anxiolytic actions, has been used in pediatric populations.Several prospective clinical trials in children have shown that dexmedetomidine significantly reduces the incidence of EA prior to recovery from sevoflurane anesthesia. However, the effect of dexmedetomidine premedication on emergence agitation has not been fully evaluated. The purpose of the present study was to verify the hypothesis that intranasal premedication with dexmedetomidine is effective in reducing emergence agitation after sevoflurane anaesthesia.

A Study on the Effects of Midazolam on Delirium After Sevoflurane Anesthesia in Pediatric Strabismus...

ChildAnesthesia Morbidity1 more

Sevoflurane with its rapid induction and emergence, hemodynamic stability, and nonirritating airway properties, has acquired widespread acceptance in children. However, sevoflurane has been reported to be associated with emergence agitation in children, with a reported incidence of up to 80%. The purpose of this study is to verify that the prophylactic use of midazolam, which is a GABA A receptor inhibitor, given five minutes before the end of strabismus surgery reduces the incidence of emergence agitation after sevoflurane anesthesia in children. Simultaneously, this study aims to find out the proper dose of midazolam with minimum disturbance to patient's emergence time.
