Jong Ho Ahn, Haejung Paik
PURPOSE: To evaluate the relationship between initial postoperative overcorrection and long-term surgical success in exotropia patients. METHODS: The medical records of 46 patients who underwent surgery for intermittent exotropia after the age of 18 were enrolled. Enrolled patients also had at least 2 years of postoperative follow-up. Based on the initial postoperative deviation at distance measured by prism and the alternating cover test at 1 week, patients were assigned to one of the following groups: group A included patients who demonstrated any esodeviation, while group B included patients who showed orthophoria to exodeviation of 10 prism diopters...

Objective: To observe the influence of exogenous insulin-like growth factor-Ⅰ(IGF-Ⅰ) on the expression of myocyte differentiation factor 5 (Myf5) and transforming growth factor β1(TGF-β1) in medial rectus muscle of cat model with strabismus. Methods: Experiment research. Twenty-seven kittens which were in sensitive period of visual development (4-6 weeks old), were randomly divided into experimental, control and blank control groups by random numbers table method. Each experimental group was further divided into 3 sub-groups (4 weeks, 8 weeks and 12 weeks) based on drug intervention time, hence 3 kittens in each sub-group...

Seung-Hyun Kim, Hyun Jin Shin
PURPOSE: To determine whether an infratrochlear nerve block (ITB) can reduce the oculocardiac reflex (OCR) during strabismus surgery on the medial rectus muscle (MR). METHODS: This prospective, randomized single-masked study included 60 patients with intermittent exotropia scheduled for unilateral MR resection/lateral rectus recession under general anesthesia. Patients were randomly allocated to receive a regional nerve block of the infratrochlear nerve (ITB group) prior to surgery or standard treatment without a nerve block (control group)...

PURPOSE: To evaluate the use of immediate postoperative alignment measurements as a predictor of future alignment stability in fixed suture strabismus surgery. METHODS: Forty-seven patients were prospectively evaluated after undergoing horizontal or vertical rectus muscle surgery using a fixed suture technique. Alignment measurements were taken approximately 1 hour, 1 to 3 weeks, and 2 to 3 months postoperatively. A Spearman correlation coefficient was used to compare measurements from the immediate postoperative period to the 2- to 3-month postoperative period...

PURPOSE: To evaluate a group of infants with this disorder to determine the long-term outcome of surgery and to assess the need for neurologic evaluations. METHODS: This interventional case series reviewed the records of infants who underwent surgery for the treatment of exotropia with onset during the first year of life. The preoperative ophthalmic and systemic findings, treatment, and developmental and ophthalmic outcomes were reviewed. Surgery was considered successful if the horizontal deviation was less than 10 prism diopters (PD)...

SIGNIFICANCE: Ocular myasthenia gravis is a localized form of myasthenia gravis, which is a postsynaptic disorder of the neuromuscular junction that causes fluctuating weakness of extraocular muscles resulting from autoimmune mechanisms. In women with myasthenia, changes in sex hormone levels and administration of corticosteroids can trigger or worsen symptoms of myasthenia gravis. PURPOSE: To describe a case of seronegative ocular myasthenia gravis whose first symptom appeared a day after in vitro fertilization procedure...

INTRODUCTION: Consecutive exotropia is one of the complications of esotropia surgery. Its prevalence is estimated at 4%-27%. The aim of this study was to identify the risk factors for consecutive exotropia in the aftermath of surgical treatment of esotropia. METHODS: Seventy-four patients examined in our strabismus consultation for a consecutive exotropia from January 2010 to June 2016 were retrospectively included. The age of onset of esotropia, the presence of amblyopia, the age of esotropia surgery and chosen procedure, the refractive errors, the anomalies of ocular motility, the age of onset of the consecutive exotropia and its angle of deviation were reported...

Congenital sodium diarrhea is a rare and life-threatening disorder characterized by a severe, secretory diarrhea containing high concentrations of sodium, leading to hyponatremia and metabolic acidosis. It may occur in isolation or in association with systemic features such as facial dysmorphism, choanal atresia, imperforate anus, and corneal erosions. Mutations in the serine protease inhibitor, Kunitz-Type 2 (SPINT2) gene have been associated with congenital sodium diarrhea and additional syndromic features...

Objective This study was performed to investigate structural abnormalities of the white matter in patients with comitant exotropia using the tract-based spatial statistics (TBSS) method. Methods Diffusion tensor imaging data from magnetic resonance images of the brain were collected from 20 patients with comitant exotropia and 20 age- and sex-matched healthy controls. The FMRIB Software Library was used to compute the diffusion measures, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD)...
