Filter by:V pattern strabismus is the commonest of alphabet pattern. Its identification is essential to plan a proper surgical management. Graded recession is a very logical approach to treat inferior oblique overaction (IOOA). The aim Is to evaluate the efficacy of graded recession of inferior oblique muscle for correction of different grades of V pattern.
Interventional case series. Non-operated patients with an indication of medial rectus muscle weakening surgery (deviation up to 20 PD) who could cooperate with topical or sub-Tenon's anesthesia. Clinical workup includes routine complete ophthalmological evaluation. One double needle 6/0 Mersilene suture is used on each side of the muscle at 4 mm distance of the insertion and pulled / stretched to insert in the sclera 3-5 mm posterior to the muscle locking passes. Seven patients with esotropia of 12-20 PD were included.
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.
The aim of this interventional, cross-sectional study is to evaluate the performance and the safety of the medical device software S360. This clinical investigation is performed in order to demonstrate the conformity of the medical device, when operating under the normal conditions of its intended use, in accordance with the General Safety and Performance Requirements pertaining to clinical evaluation of the device regarding the Medical Device Regulation (MDR) 2017/745 (EU).
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.
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.
The purpose of this study will be focused on the following issue: 1. The aim of this study is to determine therapeutic effect of postoperative eye exercises on improving eye control after the strabismus surgery. HYPOTHESES: It will be hypothesized that: • Eye exercises have a positive effect on improving eye control post strabismus surgery. RESEARCH QUESTION:" • Do postoperative eye exercises improve eye control post strabismus surgery?
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
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.
Visual screening is necessary among pre-school children as they found themselves in a critical period of visual developement. To date, there are no national vision screening program that has been implemented nationwide. Vision is a pilot feasibility multicentric cluster study comparing the sensitivity of "AFSOP 3 dimensional visual screening protocol in a population of 3 to 4-year-old pre-school children conducted in 4 kindergarten preschools in Paris with gold-standard ophthalmic examination confirmation.
