Filter by: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.
Objective: To find out how much visual improvement is possible in severe amblyopia using full-time occlusion therapy with an eye patch and to see if improvement is influenced by the patient's age. Methods: An interventional clinical trial of 115 consecutive cases with unilateral, severe amblyopia was conducted at a tertiary referral center from Jan 2010 to Oct 2012. Patients were divided into three age groups: 3-7 years (n= 38), 8-12 years (n=41), 13-35 years (n=36). After a complete ophthalmological examination by a single ophthalmologist, cases with organic visual loss were excluded; cases with previous part-time occlusion therapy that had failed were included in the study. Patients were given optimal refractive correction for a month, followed by full-time occlusion therapy along with near visual activities for 3-4 hours/day. The therapy was continued until maximum visual recovery was achieved (6/6 Snellen's). Therapy was gradually reduced and stopped. Patients were followed-up regularly for the next 18 months.
This study is trying to see if using precedex pre-operatively prevents emergence delirium in pediatric (ages 1-7) patients undergoing strabismus surgery.
To identify vision-screening tests that can accurately predict those three- and four-year old preschoolers who would benefit from a comprehensive vision examination because of signs of amblyopia, strabismus, and/or significant refractive error.
To test the hypothesis that correction with bifocal spectacle lenses rather than single-vision lenses will slow the progression of myopia in children with near-point esophoria. The primary outcome variable is cycloplegic refraction as measured with an automated refractor. Axial length is measured with ultrasound in order to test the corollary hypothesis that use of bifocals will slow ocular growth in these myopic children. We will also examine the amount of close work performed by subjects and the degree of parental myopia as factors that may influence myopia progression.
