Phosphatidylinositol 4,5-bisphosphate (PIP2) is an important cellular effector whose functions include the regulation of ion channels and membrane trafficking. Aberrant PIP2 metabolism has also been implicated in a variety human disease states, e.g., cancer diabetes. Here we report that familial Alzheimer's (FAD)-associated presenilin mutations cause imbalance metabolism. We find transient receptor potential melastatin 7 (TRPM7)-associated Mg2+ -inhibited cation (MIC) channel underlies...
Purpose To evaluate the performance of macular ganglion cell-inner plexiform layer (mGCIPL) measurement with Cirrus high-definition (HD) optical coherence tomography (OCT) for early detection optic chiasmal compression. Methods Forty-six eyes 46 patients compression caused by a pituitary adenoma (PA group), 31 normal tension glaucoma (NTG and 32 participants (control group) were enrolled. The PA group was subdivided into two subgroups, which comprised temporal visual field (VF) defects...
Purpose The outbreak of coronavirus disease 2019 (COVID-19) has caused many children to stay indoors. Increased near work and insufficient outdoor activities are considered important risk factors for myopic progression. This study aimed compare the changes in progression before after COVID-19 treated with low-concentration atropine. Methods records 103 eyes who were atropine eye drops retrospectively reviewed. We classified according concentration children’s age. beginning pre-COVID-19...
AIM: To evaluate the efficacy and safety of three different concentrations diluted atropine for control myopia in Korean children, to assess risk factors associated with rapid progression. METHODS: A total 285 refractive errors within range -6 diopters (D) between 5 14 years age were included. After using 0.01%, or 0.025%, 0.05% atropine, about 1y, changes refraction, axial lengths frequency adverse events analyzed. Logistic regression analyses performed RESULTS: The mean spherical...

Postoperative nausea and vomiting (PONV) is one of the most common adverse outcomes after strabismus surgery. The primary outcome this prospective, randomized, double-blind study was to compare incidences or vomiting, patient satisfaction ondansetron ramosetron surgery under general anesthesia. secondary investigate whether number involved extraocular muscles (EOMs) in related PONV.One hundred five patients (aged 18-60 years) undergoing were allocated randomly three groups: placebo,...
Colonoscopic perforations have been managed with exploratory laparotomy, and resulted in some morbidity mortality. Recently, laparoscopic surgery is commonly performed for this purpose. The aim of study was to compare the outcomes several management strategies iatrogenic colonoscopic perforations.We retrospectively reviewed medical records patients who had treated perforation between January 2004 April 2013 at CHA Bundang Medical Center Korea.A total 41 were enrolled. Twenty underwent...
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 this to present ophthalmologic findings KIEMS. Consecutive patients with ≥ 8 prism diopters (PD) at distance or near fixation were included. Best-corrected visual acuity, cycloplegic refraction data, angles deviation several cardinal positions,...
This study was undertaken to investigate age-dependent and postmenopausal changes in the serum levels of anti-Mullerian hormone (AMH), inhibin B, insulin-like growth factor (IGF)-I, IGF-binding protein-3 (IGFBP-3), follicle-stimulating (FSH), determine which these markers best reflects aging process women. A total 144 women aged 20-59 yr were enrolled this cross-sectional study. Blood samples obtained on cycle day 3 regularly menstruating (n=111), or at random (n=33). Data analyzed with...
The purpose of this study was to identify the correlation skin toxicity and hypertension with clinical benefit in advanced hepatocellular carcinoma (HCC) patients treated sorafenib by analyzing medical records retrospectively.Data from statistically analyzed a treatment response prognosis HCC who had received at Asan Medical Center July 2010 June 2012. This investigated prognostic factors for overall survival between development toxicities hypertension.A total 99 receiving were included...
The aim was to evaluate the characteristic clinical features of posterior microphthalmos.Medical records four patients (eight eyes) between ages three and 31 years with microphthalmos were reviewed retrospectively. Thorough ocular examinations performed, including visual acuity, intraocular pressure, alignment, axial length, cycloplegic refraction, slitlamp biomicroscopy anterior segment fundus spectral-domain optical coherent tomography (SD-OCT).All subjects had presented high hyperopia...
To analyse structural characteristics and perifoveal/peripapillary vasculature by OCT in children with peripapillary hyperreflective ovoid mass-like structures (PHOMS) compare the results those of normal subjects. Forty-five patients (84 eyes) under 18 years old blurry disc margin were evaluated spectral domain-OCT swept course-OCT. Patients divided into four groups, according to presence PHOMS then size existing PHOMS. Eyes visible optic drusen (ODD) not included. Foveal avascular zone...
Purpose: To evaluate the usefulness of an anti-transforming growth factor-β (TGF-β) agent, pirfenidone (PFD) on postoperative inflammation and fibrosis following strabismus surgery in rabbits.Methods: Both eyes 16 New Zealand white rabbits underwent reinsertion superior rectus muscle (SRM). After SRM, PFD-loaded liposomes (0.5 mg/ml) were injected into right eye (PFD group) normal saline-loaded was left (control group), subconjunctivally (0.4 ml). assess inflammatory changes...
