Purpose: To characterize the choroidal morphologic and vascular features in different levels of myopes patients with myopic neovascularization (mCNV). Methods: A total 148 subjects were enrolled this cross-sectional study, including 78 low-to-moderate (LMM), 53 high (HM), 17 mCNV. Ocular biometrics measured using an optical low-coherence reflectometry device. Retinal imaging was performed enhanced depth (EDI) spectral domain coherence tomography (OCT). parameters retinal thickness volume...
Purpose: To compare structural diameters of the ellipsoid zone (EZ) and external limiting membrane (ELM) bands on spectral domain-optical coherence tomography (SD-OCT) images between vision-improved (group A) vision-unimproved B) patients, investigate connection these parameters visual prognosis. Materials Methods: Forty-five eyes 43 patients with idiopathic full-thickness macular hole closed after vitrectomy were retrospectively reviewed. Best-corrected acuity (BCVA) SD-OCT conducted...
To develop an automated image recognition software for the objective quantification of choroidal vascularity index (CVI) and thickness (CT) at different locations on images obtained from enhanced depth imaging optical coherence tomography (EDI-OCT), to validate its reliability investigate difference correlation between measurements made by manual software.A total 390 EDI-OCT scans, captured 130 eligible emmetropic or myopic subjects, were categorized into four grades in terms their...
Abstract This retrospective study aimed to investigate the changes in choroidal vascularity index (CVI) before and after surgery for idiopathic macular hole (MH). Enhanced depth imaging optical coherence tomography (EDI-OCT) images were analyzed at baseline 1-week, 1-month, 3-month postoperative visits. A total of 97 patients (97 eyes) included study. At baseline, overall CVI showed negative correlation with axial length (AL) positive central corneal thickness (CCT). There no significant...
Purpose To investigate the dynamic visual acuity (DVA) after implantation of toric bifocal or trifocal intraocular lens in age-related cataract patients. Methods This was a prospective randomized controlled trial. Of one hundred and twenty-four patients enrolled to receive unilateral phacoemulsification (939 M/MP, Carl Zeiss Meditec AG, Jena, Germany) (909 M, lenses (IOL) implantation, ninety-nine completed follow-up were included final analysis. Postoperatively, uncorrected corrected...
Abstract Purpose To quantify the changes in intraocular pressure (IOP) and corneal refraction immediately after exposure to low-pressure hypoxia at 4500 m. Methods The study group comprised six healthy male participants 20–26 years of age. Refractive values were measured with a portable refractometer handheld iCare tonometer, respectively. Measurements taken 11 altitudes (altitude 1: ground; altitude 2: 1000 m; 3: 2000 4: 3000 5: 4000 6: 7: 40 min adaptation; 8: 3500 9: 2500 10: 1500 11: end...
Abstract Background To explore the predictive value of Ellipsoid Zone (EZ) -related angle parameters for outcome primary macular hole surgery. Methods This was a retrospective study. Patients diagnosed with large (MH) (minimum diameter > 500 μm) between 2018 and 2021 were enrolled. All patients underwent 25-gauge pars plana vitrectomy, internal limiting membrane (ILM) peeling air tamponade. Spectral-domain OCT (SD-OCT) best corrected visual acuity (BCVA) measured in preoperative 2-week...
Background: Faced with epidemic conditions, healthcare workers infection (HWI) has become a serious issue which reflects the severity of pandemic conditions and an important pact on system. Hereby, we compared differences HWI during COVID-19 in two countries, Italy South Korea, have similar population demographic distribution.Methods: We collected open data updated official website about confirmed cases (HCWs) total population, then explored factors contributing to reduction HWI, including...
Abstract Objectives To evaluate the visual functions and vision-related quality of life in T2DM patients undergoing different hypoglycemic therapeutics determine how these treatments impact on patients’ performances as well changing pattern progressed. Methods We performed an online survey among 193 patients. The was consisted three parts, each documenting demographic feature, severity T2DM, functions. third part assessed with National Eye Institute Visual Functioning questionnaire-25 (NEI...
Abstract Purpose To determine the impact of type 2 diabetes mellitus (T2DM) on visual functions, identify different modifiers as risk or protective factors, and find out how these factors affect patients’ symptoms vision-related quality life a whole. Methods We performed an online survey among 1242 participants (400 patients, 842 non-patients). Demographic features severity disease were documented, while functions evaluated using National Eye Institute Visual Functioning questionnaire-25...
