Absence of Bilateral Multiple Cyclovertical Muscle Insertions in a Patient With Pfeiffer Syndrome.

The authors present a case of absent multiple extraocular muscle insertions in Pfeiffer syndrome. An 8-year-old girl with Pfeiffer syndrome presented with V-pattern exotropia and left hypertropia. The absence of bilateral superior oblique, bilateral superior rectus, and left inferior rectus muscle insertions was found intraoperatively.

Unilateral recession and resection surgery with adjustable suture in adult sensory exotropia: long-term success and exotropic drift.

We included adult patients (age ≥18 years) with sensory exotropia who underwent unilateral lateral rectus recession with adjustable suture and medial rectus resection with at least 2-year follow-up. Preoperative and postoperative data was collected. Either Krimsky or alternate and prism cover testing was used to measure the angle of deviation depending on patients' fixation ability.

Normal Range of Ocular Ductions in Various Age Brackets by Prism Shifting Light-Reflex Test.

Purpose: To introduce a new direct measurement method for ocular ductions by shifting light reflex with plastic prism [Prism Shifting Light-Reflex Test (PLR test)]. We used it to establish normative values of ocular ductions in each age bracket defined by decade and to investigate the change of ocular ductions with aging.

Methods: Participants aged 21-80 years old without paralytic or restrictive eye disease were examined.

Long-term outcome of full tendon vertical rectus transposition with Foster suture in unilateral complete sixth cranial nerve palsy.

Purpose: To evaluate the success rate and long-term motor and sensory outcomes of the full tendon vertical rectus transposition (VRT) with Foster suture for unilateral complete sixth cranial nerve palsy.

Patients And Methods: We reviewed the medical records of patients with unilateral acquired sixth cranial nerve palsy who underwent unilateral full tendon VRT with Foster suture between 2005 and 2016 and had a follow-up of ≥2 years. Data on pre- and postoperative diplopia, face turn, ocular deviation, and limitation of abduction were collected.

Relation between early postoperative deviation and long-term outcome after unilateral lateral rectus recession and medial rectus resection for adult exotropia.

Aim: To evaluate the relationship between early postoperative deviation and long-term outcome after unilateral recession and resection surgery for adult exotropia, and to evaluate exotropic shift after surgery.

Methods: This was a retroprospective study involving adult patients with exotropia who underwent unilateral recession and resection surgery and were followed up for at least 2y. The results were evaluated at 2y and the final visit.

Time of maximum cycloplegia after instillation of cyclopentolate 1% in children with brown irises.

Purpose: We aimed to 1) determine the time of maximum cycloplegia after instillation of cyclopentolate 1% in children with brown irises, 2) evaluate the correlation between the pupillary reaction and time of maximum cycloplegia, and 3) identify any side effects of the medication.

Patients And Methods: This was a prospective analytical study involving children aged 5 to 14 years who were attending refraction clinic. Cyclopentolate 1% was instilled three times at 10-minute intervals.

Outcomes of 3 or 4 Horizontal Muscles Surgery in Large-Angle Exotropia.

Purpose: To evaluate motor and sensory outcomes of 3 or 4 horizontal muscles surgery for the treatment of large-angle exotropia and to evaluate factors influencing the success rate and the relationship between initial postoperative and final motor outcomes.

Design: A retrospective analytical study.

Methods: Medical records of patients with primary large-angle exotropia [>50 prism diopters (PD)] who had 3 or 4 horizontal muscles surgery were reviewed.
