NCT ID: NCT06423820 Recruiting - Clinical trials for Postoperative Nausea and Vomiting

Preoperative Ondansetron Lozenge for Prevention of Postoperative Nausea and Vomiting in Pediatrics Undergoing Squint Surgeries

Start date: May 21, 2024
Phase: N/A
Study type: Interventional

The aim of this study is to evaluate the role of ondansetron lozenge on prevention of postoperative nausea and vomiting (PONV) in pediatrics undergoing squint surgeries.

NCT ID: NCT06302673 Recruiting - Clinical trials for Nausea and Vomiting, Postoperative

The Role Of Laserpuncture For Prevention Of Nausea And Vomiting Post Strabismus Surgery With General Anesthesia In Adult Patients

Start date: October 9, 2023
Phase: N/A
Study type: Interventional

This study to determine the effectiveness of a combination of pre-surgical laserpuncture with standard anti-emetic therapy for PONV symptoms in adult patients after strabismus surgery under general anesthesia compared to a combination of pre-surgical placebo laserpuncture with standard anti-emetic therapy. Research design using a double blinded randomized controlled trial (RCT) where research subjects and data takers who will be disguised. The research will be carried out in the Operation and Inpatient Room, Kirana Building, RSUPN Dr. Cipto Mangunkusumo (RSCM) with research subjects as adult patients undergoing strabismus surgery under general anesthesia. Assessment of nausea and vomiting using AVS ( Analog Visual Scale) consists of scoring using a score from 1-5 which indicates the severity of nausea and vomiting.

NCT ID: NCT06298929 Recruiting - Clinical trials for Partially Accommodative Esotropia

Medial Rectus Fenestration vs Recession for PAET

Start date: November 15, 2023
Phase: N/A
Study type: Interventional

This prospective comparative study aims to compare medial rectus (MR) muscle fenestration and recession in patients with partially accommodative esotropia (PAET). The main question it aims to answer is whether MR fenestration is equally effective as MR recession for PAET. All patients will receive complete ophthalmic and orthoptic assessment. Patients will be randomly allocated using a random table to one of two groups; Group 1 will receive conventional MR recession, and Group 2 will receive MR fenestration.

NCT ID: NCT06293586 Recruiting - Anesthesia, Local Clinical Trials

Comparison Between Peribulbar And Sub-tenon Blocks on Oculocardiac Reflex (OCR) During Pediatric Strabismus Surgery

Start date: December 1, 2023
Phase: N/A
Study type: Interventional

The aim of this study is to compare between peribulbar block and subtenon block as an adjunct to general anesthesia in children undergoing strabismus surgery on oculocardiac reflex (OCR), post-operative analgesia and postoperative vomiting. Both techniques will be compared to intra-operative intravenous (IV) paracetamol combined with general anesthesia as a sole anesthetic technique.

NCT ID: NCT05615519 Recruiting - Strabismus Clinical Trials

Validation of a Smartphone-based Intelligent Diagnosis and Measurement for Strabismus

Start date: December 2, 2022
Phase:
Study type: Observational

The current measurement methods of strabismus include the corneal light reflection method, prism alternate covering, etc., which especially rely on the subjective experience of doctors, and there is a large error between different measurers, leading to serious underestimation of strabismus prevalence and insufficient care for strabismus patients. Here, the investigators established and validated an artificial intelligence system to achieve an automatic diagnosis of strabismus based on patient-sourced videos of programmatic cover tests. Three-dimensional reconstruction methods are used to digitize the parameters of head and eye positions. This system has been integrated into a smartphone platform to be further validated through hospital-based and population-based clinical trials.

NCT ID: NCT05425589 Recruiting - Strabismus Clinical Trials

Adjustable Strabismus Surgery

Start date: October 1, 2017
Phase: N/A
Study type: Interventional

Strabismus, whether congenital or acquired, is a common visual and cosmetic problem, especially for the young. Adjustable suture strabismus surgery is not in vogue in our country. This technique gives the surgeon a second attempt to provide a better outcome for the patients.

NCT ID: NCT05415553 Recruiting - Clinical trials for Inferior Oblique Overaction

IOBT Versus IO-Rec for Hypertropia With IOOA (IIHIOOA)

Start date: July 1, 2022
Phase: N/A
Study type: Interventional

This is a multi-center, randomized double-blind controlled trial to compare the effectiveness of IOBT with IO-Rec for the treatment of hypertropia with IOOA. Specific Aim 1 (Primary): To study the suboptimal surgical rates between IOBT and IO-Rec for the treatment of hypertropia with IOOA. Specific Aim 2 (Secondary): To compare the surgical successful rate of IOBT with IO-Rec for the treatment of hypertropia with IOOA.

NCT ID: NCT05208658 Recruiting - Vision Disorders Clinical Trials

Characteristics of the Vergence Responses of Binocularly Normal Subjects After a Vision Therapy Protocol

Start date: September 2, 2021
Phase: N/A
Study type: Interventional

A vision therapy protocol for vergence ability is mentioned. The purpose of this study is to evaluate objectively the change in the vergence responses of binocular and accommodative normal subjects after performing a classic vision therapy protocol. This study is an interventional, cross-over, and randomized study.

NCT ID: NCT04821817 Recruiting - Strabismus Clinical Trials

Peribulbar Rocuronium in Adult Strabismus Surgery

Start date: April 3, 2021
Phase: N/A
Study type: Interventional

- This is a prospective randomized clinical study that will be carried on adult patients aged from 21-60 years and presented for strabismus surgery under peribulbar anesthesia. - Patients will be excluded if they refused to participate or had a contraindication to peribulbar anesthesia. - Patients will be randomly distributed into either control group in which peribulbar anesthesia will be performed by injection of 10 ml local anesthetic mixture composed of 4 ml of plain bupivacaine 0.5%, 4 ml of lidocaine 2% containing 50 IU, and 2 ml normal saline or rocuronium group which peribulbar anesthesia will be performed by injection of 10 ml local anesthetic mixture composed of 4 ml of plain bupivacaine 0.5%, 4 ml of lidocaine 2% containing 50 IU, and 0.06 mg/kg of rocuronium in 2 ml normal saline. - Measurements will include; - 1. Patient age, weight, height, gestational age, and gravidity. 2. The duration of globe akinesia (primary outcome). 3. The onset of lid and globe akinesia and the duration of lid akinesia 4. The onset and duration of sensory block 5. Time required to start the surgery 6. Akinesia score 7. The visual analog score (VAS) which is composed of 0-10 score will be used to assess the severity of postoperative pain (where 0=no pain and 10=severe pain), The VAS score will be evaluated 1 h, 2 h postoperative, then every 2 h till 12 h. Any patients with VAS score more than 4 received rescue analgesia in the form of 50 mg tramadol intravenous injection with the calculation of the time for the first call of postoperative analgesia. 8. Any detected complication as nausea and vomiting, pain on injection, or increased intraocular tension.

NCT ID: NCT04770519 Recruiting - Strabismus Clinical Trials

Genetic Studies of Strabismus, Nystagmus, and Associated Disorders

Start date: September 3, 2021
Phase:
Study type: Observational

Strabismus (misalignment of the eyes) often runs in families. In this study, the investigators are looking for genetic variants associated with strabismus and nystagmus. Three types of subects will be enrolled: (1) Families with at least 3 members with strabismus, (2) individuals with infantile esotropia and their parents and siblings, and (3) individuals with infantile nystagmus and their parents. Whole exome and/or whole genome sequencing will be used to identify genetic variants shared by family members with strabismus and to identify genetic causes of nystagmus.
