Active clinical trials for "Strabismus"

Assessing the efficacy of lidocaine gel 2% application 10 minutes before surgery on post operative pain and the use of analgesics postoperatively

This study was performed to assess the effects of continuous remifentanil infusion and single bolus administration of fentanyl on the incidence of emergence agitation in pediatrics undergoing strabismus surgery.

Patients scheduled for elective strabismus surgery under general anesthesia in the First Affiliated Hospital of Nanjing Medical University will be included in this study. Patients 1)ASA I or II, 2)aged 3-65 years, 3)scheduled for elective strabismus surgery under general anesthesia, will be included in the study. Patients 1)had prior PONV, 2)severe motion sickness, 3)a history of ophthalmic surgery, 4)had received drugs known to have antiemetic effects, will be excluded from the study. The primary aim is to evaluate the prophylaxis effect of penehyclidine(a novel long acting selective anticholinergic agent developed in China) on postoperative nausea and vomiting after strabismus surgery. Secondary outcomes include the effect of PONV risk factors and surgical technique on PONV rank score, occurance of oculocardiac reflex, time to extubation.

Investigators aim to determine the optimal dose of granisetron in strabismus ophthalmic surgeries under general anesthesia to prevent postoperative nausea and vomiting

INTRODUCTION. Amblyopia is defined as the loss of visual acuity (VA) in one or both eyes, without any obvious structural or pathological anomalies. Amblyopic eye should be able to regain some VA if treatment is initiated before the age of seven. It is the leading cause of monocular blindness in the 20- to 70-year olds with prevalence 2-5%. Amblyopia is mainly monocular, hence children are general asymptomatic. VA testing is the only reliable method of detecting amblyopia, and the fourth year of life is considered best for vision screening programs. AIM: The purpose of the study is to reduce the preventable vision loss. The main goal of the study is to evidence the problem of amblyopia in Zagreb and to release a model for formal, government directed vision-screening program as a Croatian public health policy. HYPOTHESIS. In Croatia, the prevalence and actual effect of amblyopia and amblyogenic factors, along with treatment efficacy is impossible to quantify, since no population-based studies have been performed regarding this issue. In addition, national screening of preschool children does not exist, while the school-entry screening is prescribed by law. The object of the study is to determine the prevalence of amblyopia in a 4-4.5 year old children of The Town of Zagreb, the efficacy of screening and effectiveness of treatment on reducing amblyopia prevalence. The primary hypothesis is defined: screening of visual acuity monocularly at distance and near in 4-4.5 year old children in Zagreb is effective in detecting amblyopia. PATIENTS AND METHODS: Monocular vision of about 7000 children/ year aged 4-4.5 for whom both parents gave consent is to be tested with Lea chart at near (40cm) and distance (3m) in the kindergartens of The Town of Zagreb. The criterion for referral to complete ophthalmological examination is VA <0.8.

This study was designed to determine the effect of the depth of anesthesia on the oculocardiac reflex (OCR) during pediatric strabismus surgery.

This study is to investigate protective effect of biodegradable collagen implant in scleral showing after lateral rectus recession in patients with exotropia.

Follow-up of pediatric patients is important for their regular ocular morbidity monitoring, especially for amblyopia management. An observatory data of 1st week (1st to 7th) of January 2019 revealed that the follow-up compliance was very low (22%) among children aged 0-16 years in the pediatric department of Bharatpur Eye Hospital. A problem tree analysis showed a lack of awareness in children and their parents regarding the importance of follow-up and patients forgetting regarding the follow-up visit, usually when there is the long duration of follow up are the major contributing factors for poor adherence to follow-up. So, an intervention study was aimed at finding the effectiveness of counseling and reminders through SMS and phone calls to improve the follow-ups. All pediatric patients 0-16 years of age with ocular conditions requiring at least 3 follow-ups in the study period (January 2021 to April 2021) will be included. Two hundred and sixty-four participants will be equally distributed to three groups: routine standard care, counseling, and reminders with SMS and phone calls. In the routine care group, children will undergo routine care as per existing practice in the hospital and there will be no additional intervention. In counseling group, in addition to routine care parents/guardians along with the child will receive counseling from a trained counselor as per the set counseling protocol in every follow-up visits and will also be provided with the disease-specific information leaflets as additional information material before the child is discharged from the department. In the SMS and phone call reminder group, in addition to routine care, parents/guardians of children will receive reminders through short messaging text (SMS) 3 days and phone calls one day prior to the scheduled visit. Compliance to follow up Participants completing all the three follow-up visits as per the schedule within the window period of +/-2 days will be considered as a complaint to follow up. However, the follow-ups of all the participants will be recorded although that is beyond the window period. The primary outcome will be measured by the proportion of children completing all three scheduled follow-ups. The ethical approval has been obtained from the Institutional Review Committee of NHRC (ERB protocol registration number 761/2020 P). Informed consent will be taken from parent and child. Conclusion: If interventions improve the follow-up rate and are cost-effective, this can be applied in all the departments of the hospital.

The purpose of this study is to compare the effect of remifentanil on postoperative vomiting in children undergoing strabismus surgery during sevoflurane anesthesia.

Current research shows low rates of quantitative vision screening at preschool ages in the medical home. This study targets providers (PCPs) to evaluate the effectiveness of a web-based intervention to improve knowledge about strabismus, amblyopia and preschool vision screening, to increase preschool vision screening rates, and to improve rates of diagnosis of strabismus and amblyopia by eye specialists.
