purpose: to study the prevalence and characteristics of accommodative esotropia (aet). methods: in a descriptive analytic study records of all patients referred from 1383 to 1388 to the strabismus clinic at nikookari eye center were reviewed and demographic data such as age, gender, refractive error, type of aet, mean deviation and amblyopia were analyzed. results: a total of 2,146 patients wer...

purpose: to report a case of partial agenesis of the inferior rectus muscle in a child who was presented because of ocular misalignment and a deficient depression of the right eye. patient and findings: the patient was a 4-year-old girl. preoperative ct scans confirmed the clinical diagnosis of inferior rectus agenesis. the patient underwent augmented transposition of horizontal recti muscles w...

Axenfeld-Rieger syndrome (ARS) is associated with ocular and systemic anomalies. PITX2 is known to be a major controlling gene in the pathogenesis of ARS and is associated with differentiation in both the neural crest and mesoderm during eye development. A 4-year-old girl with bilateral ARS had 20 prism diopters (PD) of exotropia with 30PD of A- pattern deviation, more than 20PD of dissociated ...

Vertical saccadic velocities in 10 patients who had unilateral superior oblique muscle palsy and 14 normal subjects were measured with the magnetic scleral search coil. The authors sought to determine whether downward saccades in patients who had superior oblique palsy are slow. Peak velocities of 10 degrees and 20 degrees saccades performed in the superior and inferior fields of the orbit, and...

PURPOSE To evaluate the influence of the oblique muscles surgical weakening on the horizontal alignment in the primary position (PP) and its efficacy on the correction of the "A" and "V" anisotropies. METHODS In order to study the influence of bilateral superior oblique muscles (SO) weakening on the horizontal alignment in PP, we analyzed the files of 12 patients who underwent only that opera...

[Purpose] This study aimed to determine the effects of bridge exercise performed on an unstable surface on lumbar stabilizing muscles according to the knee angle. [Subjects] Fifteen healthy adult men were selected for this study. [Methods] The study subjects performed the bridge exercise on an unstable surface and a stable surface, with the knees at different angles (45°, 90°, and 120°). An aer...

PURPOSE Surgical management of superior oblique palsy (SOP) is challenging because of combined vertical, horizontal, and torsional misalignment. The authors report the surgical results of patients with large primary position hypertropias (> 20 prism diopters [PD]) due to unilateral SOP. METHODS Criteria for success included correction of the anomalous head posture, primary position alignment ...
