To describe the clinical characteristics and outcomes of acute acquired comitant esotropia (AACE) related to excessive smartphone use in adolescents. The medical records 12 patients with AACE a history were retrospectively reviewed, duration use, angle deviation, refractive error, stereopsis, treatment options analyzed. All showed convergent ranging from 15 45 prism diopters (PD; average: 27.75 ± 11.47 PD) at far fixation. deviation was nearly equivalent for near Every patient used more than...
To determine whether acute intraocular pressure (IOP) elevation alters dynamin-related protein 1 (Drp1) as well a selective inhibitor of Drp1, mdivi-1, can block apoptotic cell death and subsequently increase retinal ganglion (RGC) survival in ischemic mouse retina.C57BL/6 mice received injections mdivi-1 (50 mg/kg) or vehicle, then transient ischemia was induced by IOP elevation. RGC measured after FluoroGold labeling. Drp1 glial fibrillary acidic (GFAP) expression distribution were...
Abstract Background To investigate the differences in refraction, accommodative factors, visual parameters, and subjective symptoms after using two types of virtual reality (VR) content with different depths perception. Methods Twenty-three volunteers, who played VR games modes (immersive non-immersive) for 30 min, were enrolled. Visual parameters examined before VR. Accommodative factors measured static dynamic methods. Subjective assessed a questionnaire. Differences according to compared,...
Abstract We investigated the effects of using a virtual reality smartphone-based head-mounted display (VR SHMD) device for 2 h on visual parameters. Fifty-eight healthy volunteers were recruited. The participants played games VR SHMD or smartphones different days. Visual parameters including refraction, accommodation, convergence, stereopsis, and ocular alignment measured choroidal thickness before after use investigated. Subjective symptoms assessed questionnaires. analyzed differences in...
We investigated the association between retinal changes measured using optical coherence tomography (OCT) and diverse clinical grading scales in patients with Parkinson's disease (PD). Seventy-four eyes of 74 de novo PD 53 age-matched control subjects were included. The thickness peripapillary nerve fiber layer (pRNFL) macular ganglion cell-inner plexiform (mGCIPL) measured. analyzed correlations OCT parameters, parameters volumetric data cerebral cortical subcortical structures. area under...
PRéCIS:: Although the circumpapillary retinal nerve fiber layer (cpRNFL) reached measurement floor, nasal macular region is important for assessing central visual function in advanced glaucoma.To investigate relationship between field (VF) and parameters obtained from spectral-domain optical coherence tomography (SD-OCT) patients with glaucoma that cpRNFL thickness floor to determine whether structural changes measured by SD-OCT are useful estimating functional status these patients.A total...
Purpose:We aimed to examine the clinical features and prognosis of ocular ischemic syndrome investigate risk factors for development neovascular glaucoma (NVG).Methods: The medical records from 25 patients (25 eyes) who were diagnosed with retrospectively analyzed.We recorded length time between symptom onset diagnosis, visual acuity, intraocular pressure, findings anterior posterior segments eye, fluorescein angiography, systemic diseases, smoking history, extent any ipsilateral carotid...
Purpose To evaluate the clinical features of peripapillary microvasculature in myopic eyes and investigate association between superficial deep microvascular density optic disc characteristics. Materials methods This cross-sectional study included one hundred fifty healthy with β-peripapillary atrophy (β-PPA). Ovality index, degree rotation, area β-PPA were measured. Superficial was measured using optical coherence tomography angiography. Logistic regression analysis performed to look for...
Abstract We investigated the relationship between microstructure of β-parapapillary atrophy (β-PPA) and morphologic features optic nerve head (ONH) posterior pole in highly myopic eyes. Eighty-nine eyes were included this study. Bruch’s membrane opening (BMO) area, lamina cribrosa (LC) thickness, anterior laminar depth, peripapillary subfoveal choroidal thickness (CT), macular (BM) length, width β-PPA with without (PPA +BM PPA −BM ) evaluated. The mean age axial length subjects 26.88 ± 2.44...
Abstract To study the usefulness of virtual reality (VR)-based training for diagnosing strabismus. Fourteen residents in ophthalmology performed at least 30 VR sessions to diagnose esotropia and exotropia. Examinations real patients with or exotropia before after were video-recorded presented a strabismus expert assess accuracy performance scores measuring deviation angle anonymization. A feedback survey regarding ease use application was conducted participants. The mean age 14 (10 men 4...
Abstract This study explored the association between foveal avascular zone (FAZ) parameters and high myopia using optical coherence tomography angiography. We divided 106 eyes of patients into quartiles based on axial length. The upper quartile was then defined as group (n = 27), while lower non-high 26). areas minor axis lengths superficial deep FAZ, perimeters major FAZ were significantly larger in with than ( P < 0.05). Inversely, subfoveal choroidal thickness thinner those myopia....
Purpose The aim of this study was to investigate the association between tear film and meibomian gland parameters in patients with normal tension glaucoma (NTG), who underwent topical prostaglandin analog (PGA) monotherapy, medication compliance. Methods Ocular surface disease index (OSDI), Schirmer's test, break-up time (TBUT), keratoepitheliopathy (KEP) score fluorescein, were assessed 45 eyes NTG (NTG group), received PGA monotherapy for more than 1 year. results compared those 40...
Transdiaphragmatic extension of pyogenic liver abscess is the rarest cause pericarditis and pleural empyema. It a rapidly progressive highly lethal infection with mortality rates reaching 100% if left untreated. However, transmission route, treatment methods prognosis have not been well studied. A 65-year-old male patient presented fever, dyspnea, right upper quadrant abdominal pain. Computed tomography chest abdomen showed huge without full liquefaction in lobe, large amount effusion, mild...
Kesterite-based Cu2ZnSn(S,Se)4 (CZTSSe) thin-film solar cells (TFSCs) are a promising candidate for low-cost, clean energy production owing to their environmental friendliness and the earth-abundant nature of constituents. However, advancement kesterite TFSCs has been impeded by abundant defects poor microstructure, limiting performance potential. In this study, we present efficient Ag-alloyed CZTSSe enabled facile metallic precursor engineering approach. The positioning Ag nanolayer in...
This study aimed to analyze the factors influencing visual field recovery after transsphenoidal approach-tumor resection (TSA-TR) in pituitary adenoma patients with defects (VFDs).We retrospectively evaluated 102 eyes of VFDs induced by adenomas who underwent TSA-TR between January 2010 and December 2015. All had been observed for more than one year. The severity VFD each patient was using mean deviation (MD) pattern standard most-affected eye. Clinical demographic data such as preoperative...
Rationale: Ectopic variceal bleeding is a rare (2–5%) but fatal gastrointestinal bleed in patients with portal hypertension. Patients ectopic manifest melena, hematochezia, or hematemesis, which require urgent managements. Definitive therapeutic modalities of varices are not yet standardized because low incidence. Various have been applied on the basis experiences experts availability facilities, varying results. Patient concerns: We encountered eight cases five last years. Diagnoses: All...
