The objective of this prospective study is the treatment of esotropia by prescribing the full precise optical correction of refractive errors in children up to 3 years old.
This study seeks to determine if bupivacaine injection of eye muscles can make them stronger and stiffer, and thereby correct the position of eyes that are turned in or mis-aligned, a condition generally termed strabismus. It seeks further to find out the different effects of various concentrations or formulations of bupivacaine, and whether addition of Botox to other eye muscles can add to the effect of bupivacaine and enhance the correction of strabismus.
Two different treatments were given to large angle horizontal strabismus (eso and exotropia) adult patients who agree to participate of the study. Inform consents were required for participants. Group 1 (12 patients) received conventional recess-resect surgery plus intraoperative injection of botulinum toxin A (5U). Group 2 (11 patients) received only conventional recess-resect surgery. The patients were randomly located in one of the groups. The angles of horizontal deviation were compared between the groups before and six months after treatment.
In most clinics, physicians reduce diopter of hyperopic glasses in older patients with accommodative esotropia. However, there are risks of decompensation in that practice. The authors are going to try measure the change of stability of eye alignment after reducing diopter of hyperopic glasses.
The goal of this study is to determine whether corrective surgery done earlier than the current standard can better improve the visual and eye movement deficits in children with infantile esotropia (crossed eyes in infancy).
Adult patients requiring surgery for esotropia will be randomized to surgery under topical anesthesia or sub-Tenon's anesthesia. Amount of surgery required with the two anesthetic procedures will be compared. Motor and sensory outcome of the two treatment groups will also be compared.
To investigate long-term treatment outcomes of patients receiving botulinum toxin A therapy for infantile and acquired esotropia.
The purpose of this study is to: - To estimate the duration of misalignment by age at presentation in infantile esotropia (infantile ET), acquired non-accommodative esotropia (ANAET) and acquired partially accommodative esotropia (APAET). - To determine the proportion of patients with angle instability in infantile ET, ANAET and APAET by length of follow-up.
Infantile esotropia is corrected in most cases by bilateral recession of the medial rectus muscles (BR) or by unilateral recession of the medial rectus muscle and resection of the lateral rectus muscle (RR). We compared the outcome of these techniques in a randomized prospective study.
