Abstract
OBJECTIVE There exists limited comprehensive evidence on the potential association between non-cardiac comorbidities and myocardial infarction (MI). Thus, we conducted an umbrella review of existing meta-analyses to provide a broad understanding of non-cardiac health outcomes associated with MI. MATERIALS AND METHODS The primary focus on the prevalence of related health outcomes in patients with MI was systemically searched. Each original meta-analysis that was included had its methodological quality evaluated by a Measurement Tool Assessment Systematic Reviews 2 (AMSTAR2). To evaluate the certainty in the evidence for each outcome, we employed GRADE and the Joanna Briggs Institute Prevalence Critical Appraisal Tool. The protocol was registered in PROSPERO (CRD42023458642). RESULTS We identified seven meta-analyses comprising 126 studies with 336,581 participants from 22 countries and five continents. The pooled prevalence of comorbidities in patients with MI was 39% anxiety [95% confidence interval (CI), 30-48; GRADE, very low certainty], 29% depression (95% CI, 23-36; very low certainty), 39% frailty (95% CI, 24-55; very low certainty), and 23% failure of returning to work (95% CI, 16-29; very low certainty). The diagnosis of MI was associated with an increased risk of cognitive impairment (odds ratio, 1.45; 95% CI, 1.10-1.92; moderate certainty). Among frail patients, MI was associated with an increased risk of major bleeding (relative risk, 1.93; 95% CI, 1.08-3.45; low certainty) and mortality (relative risk, 2.29; 95% CI, 1.48-3.53; moderate certainty). However, we did not find any evidence of cancer risk associated with the development of MI. CONCLUSIONS Our umbrella meta-analysis provided comprehensive evidence of the association between MI and several non-cardiac health conditions. The robustness of our study is attributed to the integration of evidence across several studies, thus, these insights offer valuable treatment options for policymakers and physicians to develop personalized health strategies.

Abstract
We extend gigahertz time-domain imaging to a wideband investigation of the eigenstates of a phononic crystal cavity. Using omnidirectionally excited phonon wave vectors, we implement an ultrafast technique to experimentally probe the two-dimensional acoustic field inside and outside a hexagonal cavity in a honeycomb-lattice phononic crystal formed in a microscopic crystalline silicon slab, thereby revealing the confinement and mode volumes of phonon eigenstates-some of which are clearly hexapole in character-lying both inside and outside the phononic-crystal band gap. This allows us to obtain a quantitative measure of the spatial acoustic energy storage characteristics of a phononic crystal cavity. We also introduce a numerical approach involving toneburst excitation and the monitoring of the acoustic energy decay together with the integral of the Poynting vector to calculate the Q factor of the principal in-gap eigenmode, showing it to be limited by ultrasonic attenuation rather than by phonon leakage to the surrounding region.

Abstract
BACKGROUND To investigate the surgical outcomes of basic-type exotropia in patients with hyperopia. METHODS The medical records of patients who underwent surgery for basic-type exotropia and had been followed up for ≥ 2 years were retrospectively recruited. Patients with myopia and spherical equivalent (SE) < -1.0 diopters (D) were excluded. The patients were classified according to the SE: group H had a SE ≥ + 1.0 D, and group E had -1.0 ≤ SE < + 1.0 D. The surgical success rate and sensory outcome were compared. Surgical success was defined as exodeviation ≤ 10 prism diopters (PD) and esodeviation ≤ 5 PD at 6 m fixation. Stereoacuity was measured using the Titmus Preschool Stereoacuity Test. RESULTS Seventy-five patients (24 males and 51 females, mean age 5.1 ± 2.6 years, range 2.7-14.8) were included. The SE ranged from -0.9 to 4.4 and 21 patients were classified into group H and 54 into group E. The success rates were higher in group H than in group E during the entire follow-up period, but the differences were significant only at the final examination. At the final follow-up, 11 of the 21 (52.4%) patients in group H and 15 of the 54 (27.7%) in group E maintained successful alignment, whereas 10 (47.6%) and 38 (70.4%) patients exhibited recurrence. Overcorrection was exhibited in one (1.9%) patient in group E. Sensory results were comparable between the groups. The follow-up period did not differ between the two groups. The survival analysis showed no difference in the surgical results between the two groups. CONCLUSIONS Surgery for basic-type intermittent exotropia resulted in superior outcomes in patients with hyperopia compared to those with emmetropia.

Abstract
STUDY QUESTION Do cortisol/glucocorticoid receptors play an active role in the human ovary during ovulation and early luteinization? SUMMARY ANSWER The ovulatory hCG stimulation-induced glucocorticoid receptor signaling plays a crucial role in regulating steroidogenesis and ovulatory cascade in human periovulatory follicles. WHAT IS KNOWN ALREADY Previous studies reported an increase in cortisol levels in the human follicular fluid after the LH surge or ovulatory hCG administration. However, little is known about the role of cortisol/glucocorticoid receptors in the ovulatory process and luteinization in humans. STUDY DESIGN, SIZE, DURATION This study was an experimental prospective clinical and laboratory-based study. An in vivo experimental study was accomplished utilizing the dominant ovarian follicles from 38 premenopausal women undergoing laparoscopic sterilization. An in vitro experimental study was completed using the primary human granulosa/lutein cells (hGLC) from 26 premenopausal women undergoing IVF. PARTICIPANTS/MATERIALS, SETTING, METHODS This study was conducted in a private fertility clinic and academic medical centers. Dominant ovarian follicles were collected before the LH surge and at defined times after hCG administration from women undergoing laparoscopic sterilization. Primary hGLC were collected from women undergoing IVF. hGLC were treated without or with hCG in the absence or presence of RU486 (20 µM; dual antagonist for progesterone receptor and glucocorticoid receptor) or CORT125281 (50 µM; selective glucocorticoid receptor antagonist) for 12 or 36 h. The expression of genes involved in glucocorticoid receptor signaling, steroidogenesis, and ovulatory cascade was studied with RT-quantitative PCR and western blotting. The production of cortisol, corticosterone, and progesterone was assessed by hormone assay kits. MAIN RESULTS AND THE ROLE OF CHANCE hCG administration upregulated the expression of hydroxysteroid 11-beta dehydrogenase 1 (HSD11B1), nuclear receptor subfamily 3 group C member 1 (NR3C1), FKBP prolyl isomerase 5 (FKBP5), and FKBP prolyl isomerase 4 (FKBP4) in human ovulatory follicles and in hGLC (P < 0.05). RU486 and CORT125281 reduced hCG-induced increases in progesterone and cortisol production in hGLC. The expression of genes involved in glucocorticoid receptor signaling, steroidogenesis, and the key ovulatory process was reduced by RU486 and/or CORT125281 in hGLC. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION The role of cortisol/glucocorticoid receptors demonstrated using the hGLC model may not fully reflect their physiological roles in vivo. WIDER IMPLICATIONS OF THE FINDINGS Successful ovulation and luteinization are essential for female fertility. Women with dysregulated cortisol levels often suffer from anovulatory infertility. Deciphering the functional role of glucocorticoid receptor signaling in human periovulatory follicles enhances our knowledge of basic ovarian physiology and may provide therapeutic insights into treating infertility in women. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by P01HD71875 (to M.J., T.E.C., and M.B.) and R01HD096077 (to M.J.) from the Foundation for the National Institutes of Health and the BTPSRF of the University of Kentucky Markey Cancer Center (P30CA177558).

Abstract
PURPOSE To describe clinical manifestations and short-term prognosis of ocular motility disorders following coronavirus disease-2019 (COVID-19) vaccination. METHODS Ocular motility disorders were diagnosed by clinical assessment, high-resolution magnetic resonance imaging, and laboratory testing. Clinical manifestations, short-term prognosis, and rate of complete recovery were analyzed. RESULTS Sixty-three patients (37 males, 26 females) with a mean age of 61.6 ± 13.3 years (range, 22-81 years) were included in this study. Among 61 applicable patients with sufficient information regarding medical histories, 38 (62.3%) had one or more significant underlying past medical histories including vasculopathic risk factors. The interval between initial symptoms and vaccination was 8.6 ± 8.2 (range, 0-28) days. Forty-two (66.7%), 14 (22.2%), and 7 (11.1%) patients developed symptoms after the first, second, and third vaccinations, respectively. One case of internuclear ophthalmoplegia, 52 cases of cranial nerve palsy, two cases of myasthenia gravis, six cases of orbital diseases (such as myositis, thyroid eye disease, and IgG-related orbital myopathy), and two cases of comitant vertical strabismus with acute onset diplopia were found. Among 42 patients with follow-up data (duration: 62.1 ± 40.3 days), complete improvement, partial improvement, no improvement, and exacerbation were shown in 20, 15, 3, and 4 patients, respectively. CONCLUSION This study provided various clinical features of ocular motility disorders following COVID-19 vaccination. The majority of cases had a mild clinical course while some cases showed a progressive nature. Close follow-up and further studies are needed to elucidate the underlying mechanisms and long-term prognosis.

Abstract
The Korean Intermittent Exotropia Multicenter Study (KIEMS) was a retrospective, cross-sectional and multicenter study for the investigation of intermittent exotropia involved 65 strabismus specialists from 53 institutions in Korea. Purpose of this study was to present ophthalmologic findings of intermittent exotropia from the KIEMS. Consecutive patients with intermittent exotropia of ≥ 8 prism diopters (PD) at distance or near fixation were included. Best-corrected visual acuity, cycloplegic refraction data, angles of deviation at several cardinal positions, ocular dominance, fusion control, oblique muscle function, and binocular sensory outcomes were collected. A total of 5385 participants (2793 females; age 8.2 years) were included. Non-dominant eye was more myopic than the dominant eye (- 0.60 vs. - 0.47 diopters, P < 0.001). Mean exodeviation angles were 23.5 PD at distance and 25.0 PD at near fixation. Basic type (86.2%) was the most, followed by convergence insufficiency (9.4%) and divergence excess (4.4%) types. Alternating ocular dominance and good fusion control were more common at near than at distance fixation. Good stereopsis at 40 cm was observed in 49.3% in Titmus stereo test (≤ 60 arcsec) and in 71.0% in Randot stereo test (≤ 63 arcsec). Intermittent exotropia was mostly diagnosed in childhood and patients with the condition showed relatively good binocular functions. This study may provide objective findings of intermittent exotropia in a most reliable way, given that the study included a large study population and investigated comprehensive ophthalmology examinations.

Abstract
BACKGROUND To report the clinical manifestations of non-arteritic anterior ischemic optic neuropathy (NAION) cases after coronavirus disease 2019 (COVID-19) vaccination in Korea. METHODS This multicenter retrospective study included patients diagnosed with NAION within 42 days of COVID-19 vaccination. We collected data on vaccinations, demographic features, presence of vascular risk factors, ocular findings, and visual outcomes of patients with NAION. RESULTS The study included 16 eyes of 14 patients (6 men, 8 women) with a mean age of 63.5 ± 9.1 (range, 43-77) years. The most common underlying disease was hypertension, accounting for 28.6% of patients with NAION. Seven patients (50.0%) had no vascular risk factors for NAION. The mean time from vaccination to onset was 13.8 ± 14.2 (range, 1-41) days. All 16 eyes had disc swelling at initial presentation, and 3 of them (18.8%) had peripapillary intraretinal and/or subretinal fluid with severe disc swelling. Peripapillary hemorrhage was found in 50% of the patients, and one (6.3%) patient had peripapillary cotton-wool spots. In eight fellow eyes for which we were able to review the fundus photographs, the horizontal cup/disc ratio was less than 0.25 in four eyes (50.0%). The mean visual acuity was logMAR 0.6 ± 0.7 at the initial presentation and logMAR 0.7 ± 0.8 at the final visit. CONCLUSION Only 64% of patients with NAION after COVID-19 vaccination have known vascular and ocular risk factors relevant to ischemic optic neuropathy. This suggests that COVID-19 vaccination may increase the risk of NAION. However, overall clinical features and visual outcomes of the NAION patients after COVID-19 vaccination were similar to those of typical NAION.

Abstract
Purpose: We compared bilateral lateral rectus recession with down transposition and slanted bilateral lateral rectus recession as surgical methods for convergence insufficiency-type exotropia.Methods: We included patients who underwent bilateral lateral rectus recession with down transposition or slanted bilateral lateral rectus recession for convergence insufficiency-type exotropia from January 2012 to January 2021 and observed them for more than 1 year. We retrospectively analyzed sex, age, preoperative best-corrected visual acuity, spherical equivalent, axial length, amount of surgery, and deviation angle before surgery and after surgery (immediately, 1 week, 6 months, and 1 year). We also examined surgical success and stereopsis before surgery and after 6 months and 1 year.Results: The down transposition group included 45 patients and the slanted group included 40. The deviation angle of distance, deviation angle of near and the near-distance disparity (NDD) all decreased in the down transposition group and slanted group 1 year after surgery (1.96 ± 8.77 prism diopter [PD] and 4.60 ± 4.99 PD, respectively; 5.53 ± 9.09 PD and 9.03 ± 9.09 PD, respectively; and 3.58 ± 5.26 PD and 4.43 ± 5.32 PD, respectively). Surgical success after 1 year was 55.6% in the down transposition group and 52.5% in the slanted group, and there was no significant difference between the two groups.Conclusions: In convergence insufficiency-type exotropia, both bilateral lateral rectus recession with down transposition and slanted bilateral lateral rectus recession were effective to correct the deviation angle of near, distance, and NDD. Both are suitable primary surgical methods for convergence insufficiency-type exotropia.

Abstract
Purpose: To report a case of traumatic optic neuropathy aggravated by orbital emphysema after an orbital fracture.Case summary: A 19-year-old man with no specific medical history was referred for a right orbital fracture caused by blunt trauma to the supraorbital rim of the right eye. Computed tomography (CT) showed a right orbital fracture involving the inferomedial wall and inferomedial strut. The corrected visual acuity was 0.4 in the right eye (RE) and 1.0 in the left and the intraocular pressure was 15 and 18 mmHg, respectively. Restriction on downgaze, abduction, and an indefinite relative afferent pupillary defect (RAPD) were observed in the RE. Fundus exam was non-specific other than commotio retinae on the temporal side of the macula in the RE. After 12 hours post trauma, the visual acuity of the RE had decreased to light perception. Definite RAPD was observed with optic disc swelling on the fundus photo and optical coherence tomography. Orbital CT showed air shadows, which were not seen on the initial evaluation, adjacent to the optic disc. We diagnosed traumatic optic neuropathy aggravated by orbital emphysema. High-dose intravenous steroid was given for 3 days. Despite a lateral canthotomy and cantholysis to decompress the right orbit, visual acuity did not improve above counting fingers.Conclusions: Increased intraorbital pressure and congestion caused by orbital emphysema may exacerbate traumatic optic neuropathy. Therefore, close observation is required.

Abstract
PURPOSE We report a case of optic neuropathy related to sphenoid sinus aspergillosis which showed good visual recovery with surgery and medical antifungal treatment. METHODS Observational case study Case Presentation A 62-year-old man presented with decreased visual acuity in the right eye for 3 weeks. His visual acuity was counting fingers in the right eye and 20/20 in the left eye. Relative afferent pupillary defects were detected in the right eye. Optic neuropathy related to invasive fungal sphenoid sinusitis was suspected via radiologic evaluation. Endoscopic sinus surgery was performed and histopathological examination revealed aspergillosis. Amphotericin B combined with ceftriaxone and metronidazole was started. After the fungal culture results were positive for the Aspergillus species, amphotericin B was changed to voriconazole. At 1 month after surgery, visual acuity improved to 20/25. CONCLUSION Appropriate radiologic evaluation can be helpful when optic neuropathy associated with a fungal infection is suspected, and timely surgical and medial treatment should be considered.

Abstract
Purpose: To investigate the usefulness of atropine (Isopto atropine 1% eye drops®; Alcon, Fort Worth, TX, USA) for cycloplegic refraction in patients with partially accommodative esotropia.Methods: We retrospectively analyzed the medical records of patients with partially accommodative esotropia who underwent cycloplegic refraction using both cyclopentolate and atropine at Pusan National University Hospital between November 2017 and December 2020. Patients who replaced their glasses after cycloplegic refraction with atropine were included in group 1 and all other patients were included in group 2. Clinical features and the angle of ocular deviation were compared between the two groups.Results: This study included 23 patients with a mean age of 58.2 ± 22.3 months and mean interval between the two examinations of 5.2 ± 4.1 months. Spherical equivalent was larger after cycloplegic refraction using atropine compared to cyclopentolate (+3.04 ± 1.70 and +2.31 ± 1.75 diopters, respectively; p = 0.001). Groups 1 and 2 included 19 (83%) and 4 (17%) patients, respectively. Clinical characteristics did not significantly differ between the two groups. In group 1, the angle of ocular deviation at near fixation significantly decreased from 28.7 ± 14.0 to 20.7 ± 11.6 prism diopters (p = 0.002) after correction of the refractive error.Conclusions: Cycloplegic refraction with atropine may be useful for detecting latent hyperopia and managing strabismus in patients with partially accommodative esotropia.

Abstract
PURPOSE We aimed to investigate the predictive value of retinal thickness measured by optical coherence tomography (OCT) and mass biometrics measured using magnetic resonance image (MRI) for visual recovery after surgery for removal of a mass compressing the optic chiasm. METHODS Consecutive patients who showed typical temporal visual field defect (VFD) with respect to the vertical meridian due to a chiasmal compressive mass and who underwent mass removal surgery were recruited. Ophthalmic examination was performed preoperatively and postoperatively. Retinal thickness was measured by the Cirrus OCT. The height and size of the mass and suprasellar extension (SSE) in both the sagittal and coronal planes were evaluated. Patients were divided into two groups based on the improvement in VFD (mean deviation [MD] change ≥ 5 dB: group R; others: group NR) and clinical characteristics were compared. RESULTS Fifteen patients were included in the study. Eight (53.3%) patients were allocated into group R and others (7 patients, 46.7%) into group NR. Age, sex, initial visual acuity, initial MD was not different between the two groups. The retinal thicknesses were not different while tumor height, volume, and both sagittal and coronal SSE were significantly different between the two groups. (p = 0.029, 0.014, <0.001, and <0.001, respectively) All MRI parameters showed significant predictive value for the degree of MD recovery. CONCLUSION MRI showed better predictive value than OCT in predicting postoperative VFD recovery in patients with temporal VFDs due to chiasmal compressive disorder.

Abstract
BACKGROUND Investigation of visual field defects (VFDs) is important to decide the treatment and to predict the prognosis in patients with a pituitary mass. The aim of this study was to evaluate the correlation among 2 diagnostic modalities-MRI and optical coherence tomography (OCT)-and VFDs. METHODS Consecutive patients who showed the presence of a pituitary mass on MRI and in whom ophthalmic examinations were performed were recruited. Height and volume of the mass, sagittal and coronal displacement of optic chiasm, and the direction of mass expansion were measured. Patients were divided into 2 groups according to the presence (VFD group) or absence of VFDs (no VFDs group [NVFD]). The correlation among MRI parameters, OCT parameters, and VFDs were examined, and the diagnostic values of MRI and OCT and the combined value of the 2 modalities were analyzed. RESULTS Forty-one patients were included. The greatest coefficients of determination were observed between the sagittal displacement and pattern standard deviation (PSD) (R2 = 0.3661, P < 0.001) and between the inferonasal ganglion cell-inner plexiform layer (GCIPL) and PSD (R2 = 0.4079, P < 0.001). The height and the size of the mass in the VFD group were significantly greater as 57% and 148%, respectively, and the VFD group had more severe chiasmal displacement both in the sagittal (165%) and in the coronal (178%) plane (large effect in all). All macular GCIPLs were thinner in the NVFD group (range 9%-26%, large effect), whereas only temporal (25%) and average (11%) values were among peripapillary retinal nerve fiber layers. CONCLUSIONS The highest correlations with the degree of the VFD were seen in the sagittal displacement of optic chiasm and the inferonasal GCIPL, and these parameters were correlated concurrently. Both modalities showed a good diagnostic value for discriminating VFDs.

Abstract
Background Assessing visual function in infants is usually challenging. Fix-and-Follow is a simple and popular method for assessing early development of visual perception in infants, currently however, there is no formal reproducible method for grading the capacity of fix-and-follow. This study was to develop and validate a new fix-and-follow grading system for assessing visual function development in preverbal children. Methods In this cross-sectional study, the fix-and-follow grades was evaluated in 21 consecutive preverbal children. Fixation was categorised as grade 1 if there was no response to the target and grade 2 if there was a response but only for < 3 s. Grades of 3 and 4 were assigned based capacities to (1) fix on a moving target for ≥3 s, and (2) shift fixation from one target to another. If only one of these two criteria was met, grade 3 was assigned. If both were met, grade 4 was assigned. Following was evaluated using smooth pursuit movement, where grade 1 indicated no movement, grade 2 partial movement, and grade 3 complete movement. Two ophthalmologists independently applied the grading method in all patients. Then one of two examiners repeated the examinations to investigate the intra-observer agreement of the grading system. Results Intra-observer agreement was excellent (Kappa coefficient = 0.823) and inter-observer agreement was good (Kappa coefficient = 0.625). All patients who exhibited abnormal ocular movement had score discrepancy between a new fix-and-following grading examination. Conclusions The new fix-and-follow grading scale can be applied easily in preverbal children in an office setting, and it proved reliable and reproducible.

Abstract
Purpose: To report a case of unilateral progressive atypical acute zonal outer retinitis in a healthy young female.Case summary: A 32-year-old healthy woman presented with visual disturbance in the left eye for 1 week. Best corrected visual acuity was 0.4 in the left eye. No abnormal findings were detected on brain magnetic resonance imaging and a laboratory work-up. Zonal retinal opacity around the optic nerve disc was noticed in a fundus photo which was consistent with the outer retinal signal defect on optical coherence tomography and a defect in the central visual field from perimetry. Multiple evanescent white dot syndrome was suspected based on fluorescein angiography and indocyanine green angiography. Prednisolone was prescribed. Visual acuity was reduced to hand-motion after 10 days with extended zonal retinal opacity. No virus was detected by multiplex polymerase chain reaction of the aqueous humor. The lesion did not improve despite high-dose intravenous steroid and antiviral treatment.Conclusions: Visual function was lost with the progression of outer retinitis. This case differed from previous cases as the outer retinitis progressed rapidly from the posterior pole to the peripheral retina. It was named fulminant progressive atypical acute zonal outer retinitis.

Abstract
<p>Idiopathic intracranial hypertension (IIH) is a syndrome defined by elevated intracranial pressure without any abnormal findings. In the present study, we report a rare case of IIH in a patient after ventriculoperitoneal shunt (VPS) due to infant hydrocephalus. A 13-year-old girl with a history of VPS due to infant hydrocephalus was admitted to emergency room with the complaint of severe headache and visual disturbance. Brain computed tomography showed normal findings. However, based on the measurement by lumbar puncture, her cerebrospinal fluid (CSF) pressure was observed to be very high. The shunt function test revealed a VPS malfunction. Thus, we conducted VPS revision in this patient. All symptoms improved immediately after the revision. Thus, it is proposed that IIH should be considered for patients with visual disturbance and severe headache after VPS due to infant hydrocephalus without ventriculomegaly.

Abstract
Purpose To investigate the clinical features of strabismus in patients with congenital optic disc anomaly and compare and analyze the characteristics of patients who showed changes in the strabismus pattern with those who did not. Methods Medical records of the patients who were diagnosed with both strabismus and congenital optic disc anomaly and followed-up for ≥1 year were reviewed retrospectively. Clinical characteristics and ophthalmic features at the initial visit and final follow-up were assessed. Patients with a change in the direction of strabismus or a difference of >10 prism diopters in the deviation angle during the follow-up period were allocated to the changed group. The remaining patients were assigned to the unchanged group. The clinical characteristics of the two groups were compared. Results Twenty-eight patients (15 boys) were included (mean age, 39.0 months; range, 5–150 months). Three (10.7%) patients were born preterm and four (14.3%) had other underlying systemic disease. Sixteen (57.1%) patients had exotropia, and 12 (42.9%) had esotropia. Concurrent vertical strabismus was present in three (10.7%) patients. Strabismus features changed in 14 (50.0%, changed group) patients and remained unchanged in 14 (50.0%, unchanged group) patients. Age, sex, and laterality did not differ between groups. Preterm birth history (n = 3) and combined systemic disease (n = 4) were only observed in the changed group (p = 0.111 and p = 0.049, respectively). Conclusions Considering the possibility of changes in strabismic features, close monitoring of patients with strabismus combined with congenital disc anomaly is essential, particularly in those with preterm birth history or underlying systemic conditions.

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.
