Summary

This study is a prospective, randomized, double-blind cohort study aimed at assessing the accuracy of the preoperative tilted gaze target test in predicting the degree of improvement in compensatory head position after surgery in children with superior oblique muscle palsy.

Detailed description

This is a prospective, randomized, double-blind cohort study conducted from May 2023 to April 2024. The study aims to evaluate the effectiveness of a non-human contact gaze tilt test in the diagnosis of children with superior oblique Muscle Palsy. Patients who met the inclusion criteria for outpatient and inpatient ophthalmic surgery for strabismus and pediatric ophthalmology were enrolled after signing a written informed consent. The gaze tilt test was added to the normal treatment process and performed by a professional ophthalmologist who was not involved in the treatment process. The test involved playing a small animated video with a visual mobile device at a distance of 33 cm and 3 m, respectively, to determine the optimal angle of head position improvement and the spatial tilt angle of the screen relative to the orthostatic position. A third-party analysis of the data was performed to identify myotonic and oculocutaneous tilts and compared with the results of the conventional test. The study aims to clarify the authenticity, reliability, and practicality of the gaze object tilt test in diagnosing and treating oculocutaneous squint.

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Tilted Gaze Target Tast	Tilted gaze target tast is playing a small animated video with a visual mobile device at a distance of 33 cm and 3 m, respectively, to determine the optimal angle of head position improvement and the spatial tilt angle of the screen relative to the orthostatic position.It will be conducted during the first visit. Preoperative intervention will also be conducted before surgery. Postoperative interventions will be conducted at one day, one month, and six months after surgery.
DIAGNOSTIC_TEST	Conventional Examination Methods	The conventional examination methods include oculomotor examination, Bielschowsky head tilt test, alternate prism cover test, prism adaptation test, and monocular cover test. They will be conducted during the first visit. Preoperative intervention will also be conducted before surgery.Postoperative interventions will be conducted at one day, one month, and six months after surgery.
