Abstract
Ocular disease is one of the causes of abnormal head positioning. Conventionally, the behavioral characteristics of ocular torticollis patients are different from those of non-ocular torticollis patients, though research addressing the significance of this difference is yet limited. This prospective, cross-sectional study aims to develop a questionnaire based on the clinical features in children with abnormal head posture being ocularly assessed. Children aged ≥ 6 months who visited our rehabilitation medicine clinic with a chief complaint of abnormal head posture were included. Patients with apparent orthopedic and neurological diseases were excluded. A 10-item questionnaire was developed to analyze the behavioral characteristics of patients. The patients were divided into ocular and non-ocular torticollis groups according to ophthalmologic examination results. Thirty-four and 13 patients were assigned to the non-ocular torticollis and ocular torticollis groups, respectively. Five questions were finally selected and the questionnaire was scored as the sum of the scores for the each questions (yes = 1 point, no = 0 point). The median (interquartile range) score of the ocular torticollis group (3.0 (3.0-4.0)) was significantly higher than that of the non-ocular torticollis group (2.0 (1.0-3.0); p = 0.000).Conclusion: Our parent-reported torticollis assessment questionnaire may be useful for screening ocular torticollis. What is known: • Ocular disease is one of the various causes of abnormal head positioning. • The behavioral characteristics of patients with ocular torticollis are different from those of patients with non-ocular torticollis; research on this matter is limited. What is new: • We delveloped a questionnaire to differentiate ocular and postural torticollis and the score of the questionnaire was different between patients with or without ocular disease. • The questionnaire based on behavioral characteristics may help screening and determining the need of ophthalmic evaluation in patients with torticollis.

Abstract
PURPOSE To evaluate the ophthalmic features of Rathke's cleft cyst (RCC) and its association with radiological characteristics. METHODS In this retrospective single-center study, patients who showed typical findings suggestive of RCC on magnetic resonance imaging (MRI) and underwent relevant ophthalmic examination were recruited retrospectively. Patients were stratified into two groups according to the presence or absence of ophthalmic symptoms related to RCC. We reviewed patients' demographic information, initial symptoms, endocrinological status, ophthalmic features, and characteristics of MRI. Height, size and location of RCC, as well as the optic chiasm displacement assessed from MRI. RESULTS Thirty-three patients (20 women and 13 men) were included in this study from among 335 patients with RCC on MRI. Fifteen patients had ophthalmic manifestation related to the cyst (Ophthalmic group), whereas 18 patients were not (Non-ophthalmic group). Headache was the most common initial symptom (15 patients, 45.5%), followed by visual disturbance (7, 21.2%), diplopia (1, 3.0%), retro-orbital pain (1, 3.0%), galactorrhea (1, 3.0%), and peripheral extremity discomfort (1, 3.0%). In seven asymptomatic patients (21.2%), the lesion was an incidental finding during a regular medical examination. Ophthalmic manifestation included visual field defect (14 patients, 93.3%) and diplopia (1 patient, 6.7%). The height, volume, and the coronal and sagittal displacements were larger in the ophthalmic group (P < .001, all). Eleven patients who manifested ophthalmic symptoms underwent excision surgeries and nine of them (81.8%) experienced visual function improvement. CONCLUSION Appropriate ophthalmic examinations are warranted in patients with RCC, and treatment should be actively considered in patients with ophthalmic manifestations.

Abstract
PURPOSE To evaluate the peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell-inner plexiform layer (GCIPL) measurements using spectral domain optical coherence tomography (SD-OCT) in patients with chiasmal compression and analyze the diagnostic value of a neural network model. METHODS Forty-seven patients with chiasmal compressive disorder were recruited and divided into two groups depending on the visual field defect (perimetric; group 1 and preperimetric; group 2). Fifty-seven normal subjects were also recruited (group 3). Peripapillary RNFL and macular GCIPL were analyzed in each group. A multilayer perceptron was trained using a training dataset and derived a neural network model. The diagnostic performances were compared using the area under the receiver operating curve (AUROC) between each parameters and neural network model. RESULTS All macular GCIPL parameters, except inferotemporal GCIPL thickness, were thinner in group 1 than in group 2 and group 3, with barely any difference between group 2 and group 3 parameter values. The diagnostic power of the neural network model, minimum GCIPL, and inferonasal GCIPL were superior when compared with other parameters; the diagnostic values of these three parameters are not significantly different in discriminating the patients and normal control. However, the neural network exhibited the best diagnostic power in distinguishing group 2 and group 3. CONCLUSION Macular GCIPL was reduced in chiasmal compression patients with visual field defect which was not evident in the preperimetric state. Neural network model showed superior diagnostic value in discriminating the preperimetric patients from normal control. The results suggest that neural networks may be helpful in the early diagnosis of chiasmal compression.

Abstract
Purpose: To investigate the correlation between clinical features of strabismus and motor dysfunction classified according to the Gross Motor Function Classification System (GMFCS) in patients with spastic cerebral palsy (CP).Methods: In this retrospective, cross-sectional study in single tertiary medical center, 62 patients who are diagnosed with spastic CP who had an ophthalmic examination between 2006 and 2014 were included. Only patients with vision sufficient to fixate were included and patients with restrictive or paralytic strabismus were excluded. The types of CP were classified as diplegia, hemiplegia, or quadriplegia for distribution of motor impairment. The GMFCS was used to grade gross motor dysfunction, which was then classified as mild (grade 1, 2 and 3) or severe (grade 4 and 5) motor impairment. Strabismus was investigated in terms of direction, constancy, and deviation angle. The relationship between strabismus characteristics and the level of GMFCS and type of CP were assessed.Results: Thirty-eight and 24 patients had mild or severe motor deficit, respectively. Forty patients had strabismus, which was more frequent in patients with severe motor impairment.(P = .014) Exotropia and esotropia occurred with similar frequency. Constant and large-angle strabismus was frequently observed in patients with severe motor impairment.(P < .005, 0.027) The topographical subtype of CP was not related to clinical features of strabismus.Conclusions: The prevalence of strabismus is higher in severe motor impairment. The constancy and angle of strabismus was related to the severity of motor impairment while the topographical subtype of CP has no significant relationship.

Abstract
Whether or not epitaxially grown superconducting films have the same bulk-like superconducting properties is an important concern. We report the structure and the electronic properties of epitaxially grown Ba(Fe1-x Co x )2As2 films using scanning tunneling microscopy and scanning tunneling spectroscopy (STS). This film showed a different surface structure, [Formula: see text]R45° reconstruction, from those of as-cleaved surfaces from bulk crystals. The electronic structure of the grown film is different from that in bulk, and it is notable that the film exhibits the same superconducting transport properties. We found that the superconducting gap at the surface is screened at the Ba layer surface in STS measurements, and the charge density wave was observed at the surface in sample in the superconducting state.

Abstract
Purpose: This study was undertaken to analyze the characteristics of optic neuritis in Korean patients seropositive for Toxocara. Methods: We retrospectively reviewed data from patients diagnosed with optic neuritis and followed up for at least one month between 2012 and 2016. Patients were grouped according to Toxocara serological testing outcomes (positive or negative) and clinical characteristics were compared. Results: The seropositive and seronegative groups comprised 13 and 12 patients, respectively. The seropositive patients were older (56.8 years versus 34.5 years), reported ocular pain less frequently (30.8% versus 91.7%), and showed more frequent asymmetric optic disc swelling (72.7% versus 22.2%). During follow-up, visual acuity of all seronegative patients improved to 20/40 or better, compared with 38.5% of the seropositive group. Conclusion: Atypical features such as painless, older age, or asymmetric disc swelling in optic neuritis may be related to seropositivity for Toxocara, suggesting the possibility of undiagnosed Toxocara optic neuropathy.

Abstract
PURPOSE To investigate the long-term outcomes of intermittent exotropia surgery for children less than 4 years of age. MATERIALS AND METHODS Consecutive patients who underwent surgery for intermittent exotropia and had follow-up durations longer than 2 years were recruited. The patients were classified according to age at surgery-the patients of group 1 had undergone surgery before 4 years of age and those of group 2 at or after 4 years of age. Motor success was defined by exodeviation < 10 prism diopters (PD) and esodeviation < 5 PD at distance at 2 years postoperatively. Stereoacuity was considered as success at a value ≤ 60 arc seconds. The motor and sensory success rates as well as the surgical complications were compared. RESULTS Of the 73 patients, 36 were allocated to group 1 and 37 to group 2. At 2 years after surgery, 13 of the 36 (36.1%) patients in group 1 and 12 of the 37 (32.4%) in group 2 had achieved successful alignment; 32 (88.9%) patients in group 1 and 35 (94.6%) in group 2 achieved normal stereoacuity. No significant differences in the motor or sensory success rates were observed between the two groups (p = 0.46 and 0.32, respectively). CONCLUSIONS The surgical success rates for intermittent exotropia were comparable between the patients operated upon before 4 years of age and those operated upon after 4 years of age. The incidence of postsurgical complications was low and not significantly different between the two study groups.
