Summary: Preoperative and postoperative Lees screen was done after concomitant horizontal strabismus surgery to detect any limitation in the field of operated muscle

Summary: Determine whether full-time patching is more effective than observation for improving distance control of IXT after 3 months of treatment (on-treatment outcome).

Summary: To compare the effect of the used local anesthetics in this study on decreasing the incidence of oculocardiac reflex . To evaluate the efficacy of Articaine 4 % , mepivacaine 3% and lidocaine 2% regarding post- operative analgesia.

Summary: 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 ...

Summary: Using various adjuvants has become a trend in regional anesthesia practice to improve the quality of anesthesia and prolong postoperative analgesia. Dexmedetomidine, an alpha-2 agonist has been proposed as a safe and effective adjunct capable of extending the duration of the single-shot block

Summary: 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 a...

Summary: The overall five-year goals of the project are to develop novel technology to provide actionable new information through provision of live volumetric imaging during surgery, improving surgical practice and outcomes. The investigators believe this technology will enable novel ophthalmic and other microsurgeries not possible due to current limitations in surgical visualization.

Summary: The purpose of this study is to identify genes associated with impaired development and function of the cranial nerves and brainstem, which may result in misalignment of the eyes (strabismus) and related conditions.

Summary: Strabismus (misalignment of the eyes) often runs in families. In this study, the investigators are looking for genetic variants in families in which multiple people have strabismus. Families with at least 3 members with strabismus will be enrolled, and whole genome sequencing will be used to identify genetic variants shared by family members with strabismus.

Summary: 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 ...

Summary: Optic pathway glioma (OPG) can result in visual deterioration. Symptomatic patients often report deficits in visual acuity (VA), visual field, visual-evoked potentials (VEPs), strabismus, proptosis, disc swelling, and other visual/neurological problems. VA itself remains one of the most important outcome measures for OPG patients, with various studies showing strong ties of VA level to overall qua...

Summary: Aim 1: To determine whether use of dichoptic movies for 4 weeks may be helpful in improving control of alignment in children with intermittent exotropia (IXT), thus allowing IXT to be managed non-surgically Aim 2: To determine pre-IXT surgery use of dichoptic movies for 4 weeks post-operatively may be helpful in maintaining successful control of alignment in children who have surgical correction o...
