Purpose: To investigate the clinical efficacy of the Spot Vision Screener in measuring refractive power and detecting strabismusin pediatric patients. Methods: We retrospectively analyzed the spherical equivalent, cylinder, and strabismus using the Spot Vision Screener beforecycloplegic refraction for pediatric patients <10 years of age. We compared the spherical equivalent and cylinder using the SpotVision Screener with the results of cycloplegic refraction, and we measured the accuracy of the Spot Vision Screener in detectingstrabismus compared with the alternate prism cover test. Results: A total of 38 eyes of 19 patients were included in this study. There was no significant difference in spherical equivalentbetween the Spot Vision Screener before cycloplegic refraction and cycloplegic refraction (paired t-test: -0.25 ± 1.12 diopters [D]vs. 0.04 ± 1.86 D; p = 0.12). There was a significant difference in cylinder between the Spot Vision Screener before cycloplegicrefraction and cycloplegic refraction, but the difference was only -0.25 D (paired t-test: -1.41 ± 1.16 D vs. -1.16 ± 1.25 D; p = 0.01).The sensitivity of the Spot Vision Screener was 42.86%, and the specificity was 66.67% for detecting strabismus. Conclusions The Spot Vision Screener was a useful instrument to measure the refractive power in pediatric patients before cycloplegicrefraction, but it had poor sensitivity and specificity for detecting strabismus.

PURPOSE: To evaluate the clinical outcomes of eyes implanted with a zonal refractive multifocal intraocular lens (IOL) with an inferior segmental near add (M-plus), and to compare the outcomes between M-plus and a diffractive-type multifocal IOL, AT LISA (366D, bifocal). METHODS: We reviewed 19 eyes from 10 patients who were implanted with M-plus and 52 eyes of 26 patients who were implanted with AT LISA. The clinical outcomes of these 2 intraocular lenses were evaluated at 1 day and 2 months postoperatively, and consisted of distant, intermediate, and near visual acuity, contrast sensitivity, degree of tilt, and decentration using anterior segment photography, depth of focus, and patient satisfaction. RESULTS: There were no statistical differences between the 2 groups with respect to distant vision, near vision, refractive error, contrast sensitivity, degree of tilt, decentration, or satisfaction score. The M-plus group demonstrated significantly better intermediate visual acuity. In the defocus curve, the M-plus group also demonstrated significantly better visual acuities for intermediate unfocused vision levels. CONCLUSIONS: The M-plus multifocal IOLs are able to provide satisfactory distant and near visual acuity and visual function. The M-plus multifocal IOLs provide better intermediate vision than the AT LISA.

PURPOSE: Using a visual analogue scale, patients pain was compared according to injection site during intravitreal injection. METHODS: A prospective, clinical trial was conducted on 171 eyes of patients experiencing age-related macular degeneration, diabetic retinopathy, retinal vein occlusion, or central serous chorioretinopathy. After determining the anatomic quadrant of the injection site, patients were randomized to receive intravitreal bevacizumab, aflibercept, ranibizumab, or dexamethasone injection. Fifteen minutes after the injection, patients completed a survey about pain using a visual analogue scale from 0 (no pain) to 10 (unbearable pain). RESULTS: According to the visual analogue scale, pain score was 3.20 at the superotemporal site, 3.03 at the superonasal site, and 2.35 at the inferonasal site. Pain was lowest when injected in an inferotemporal site (p = 0.012). CONCLUSIONS: Intravitreal injection at an inferotemporal site can help reduce patient pain.

OBJECTIVE: This study is to report our experience of 40 cases of spinal schwannoma. METHODS: From 1995 to 2006, medical records were retrospectively reviewed in 40 cases of spinal schwannoma. RESULTS:We treated 40 spinal schwannomas in 38 (22 male and 16 female) patients. The mean age was 50.2. Four cases were sited in the cervical spine, 11 cases in the thoracic spine, and 25 cases in the lumbar spine. Two patients showed recurrences. Thirty-eight cases were intradural-extramedullary type and 2 cases were extradural. Two cases (5%) including 1 recurred case had no postoperative motor improvement. Ninety-five percents of patients improved on postoperative motor grade. CONCLUSION: Spinal schwannoma is mostly benign and extramedullary tumor. There were 2 recurred cases (5%) that had history of previous subtotal removal at first operation and had shown worse prognosis compared with the cases without recurrence. To reduce the recurrence of spinal schannoma, total excision of tumor mass should be done.

OBJECTIVE: Subdural hygroma (SDG) is a complication occurring after head trauma that may occur secondary to decompressive craniectomy (DC). However, the mechanism underlying SDG formation is not fully understood. Also, the relationship between the operative technique of DC or the decompressive effect and the occurrence and pathophysiology of SDG has not been clarified. Purpose of this study was to investigate the risk factors of SDG after DC in our series. METHODS: From January 2004 to December 2008, DC was performed in 85 patients who suffered from traumatic brain injury. We retrospectively reviewed the clinical and radiological features. For comparative analysis, we divided the patients into 2 groups : one group with SDG after craniectomy (19 patients; 28.4% of the total sample), the other group without SDG (48 patients; 71.6%). The risk factors for developing SDG were then analyzed. RESULTS: The mean Glasgow Outcome Scale (GOS) scores at discharge of the groups with and without SDG were 2.8 and 3.1, respectively (p<0.0001). Analysis of radiological factors showed that a midline shift in excess of 5 mm on CT scans was present in 19 patients (100%) in the group with SDG and in 32 patients (66.7%) in the group without SDG (p<0.05). An accompanying subarachnoid hemorrhage (SAH) was seen in 17 patients (89.5%) in the group with SDG and in 29 patients (60.4%) in the group without SDG (p<0.05). Delayed hydrocephalus accompanied these findings in 10 patients (52.6%) in the group with SDG, versus 5 patients (10.4%) in the group without SDG (p<0.05). On CT, compression of basal cisterns was observed in 14 members (73.7%) in the group with SDG and in 18 members of the group without SDG (37.5%) (p<0.007). Furthermore, tearing of the arachnoid membrane, as observed on CT, was more common in all patients in the group with SDG (100%) than in the group without SDG (31 patients; 64.6%) (p<0.05). CONCLUSION: GOS showed statistically significant difference in the clinical risk factors for SDG between the group with SDG and the group without SDG. Analysis of radiological factors indicated that a midline shifting exceeding 5 mm, SAH, delayed hydrocephalus, compression of basal cisterns, and tearing of the arachnoid membrane were significantly more common in patients with SDG.

OBJECTIVE: To characterize perioperative biomechanical changes after thoracic spine surgery. METHODS: Fifty-eight patients underwent spinal instrumented fusions and simple laminectomies on the thoracolumbar spine from April 2003 to October 2008. Patients were allocated to three groups; namely, the laminectomy without fusion group (group I, n = 17), the thoracolumbar fusion group (group II, n = 27), and the thoracic spine fusion group (group III, n = 14). Sagittal (ADS) and coronal (ADC) angles for adjacent segments were measured from two disc spaces above lesions at the upper margins, to two disc spaces below lesions at the lower margins. Sagittal (TLS) and coronal (TLC) angles of the thoracolumbar junction were measured from the lower margin of the 11th thoracic vertebra body to the upper margin of the 2nd lumbar vertebra body on plane radiographs. Adjacent segment disc heights and disc signal changes were determined using simple spinal examinations and by magnetic resonance imaging. Clinical outcome indices were determined using a visual analog scale. RESULTS: The three groups demonstrated statistically significant differences in terms of angle changes by ANOVA (p < 0.05). All angles in group I showed significantly smaller angles changes than in groups II and III by Turkey's multiple comparison analysis. Coronal Cobb's angles of the thoracolumbar spine (TLC) were not significantly different in the three groups. CONCLUSION: Postoperative sagittal balance is expected to change in the adjacent and thoracolumbar areas after thoracic spine fusion. However, its prevalence seems to be higher when the thoracolumbar spine is included in instrumented fusion.

Intestinal pseudo-obstruction is characterized by symptoms and signs of mechanical bowel obstruction in the abscence of an occluding lesion of the intestinal lumen. The chronic forms of intestinal pseudo-obstruction are separated into primary and secondary in according to the underlying disorders. primary or chronic idiopathic intestinal pseudo-obstruction(CIIP) is not associated with systemic illness and a progressive nature with relapses and remissions. Since Dyer described the rare histologic subtype of idiopathic pseudo-obstruction, the primary abnormality is in the myenteric plexus of the bowel at first in 1969, only few cases are reported. We report a case of CIIP caused by degeneration of myenteric plexus of the colon and he was successfully treated with surgical management.

PURPOSE: The purpose of this study was to determine the prevalence of symptomatic femoroacetabular impingement (FAI) in athletic patients. MATERIALS AND METHODS: From July 2003 to May 2013, 388 patients (422 hips) who underwent arthroscopic surgery for FAI were evaluated demographic characteristics. The patients' age, gender, diagnosis, and type of sports were analyzed using medical records and radiography. RESULTS: Among 422 hips in 388 patients, 156 hips were involved with sports. Among the 156 hips, 86, 43, and 27 hips were categorized as cam, pincer, and mixed type, respectively. Types of sports were soccer, baseball and taekwondo which showed 44, 36 and 35 hips, respectively. Also, cases related to sports according to age were 63 hips for twenties and 12 hips for teenagers in which the two showed highest association to FAI. The kinds of sports that showed high association were 28 hips of soccer and 20 cases of martial arts such as taekwondo and judo for twenties and 9 hips of martial arts for teenagers which was the highest. CONCLUSION: FAI usually occurs in young adults and is highly related to sports activity. Most of the FAI type related to sports activity was cam type, and soccer and martial arts such as taekwondo were the most common cause of it.
