See editorial "Successful transition to the QFT-PLUS assay, but more is needed for diagnosis of latent tuberculosis infection" on page 298.

Central retinal artery occlusion (CRAO) is considered an ophthalmologic emergency. The prognosis of this disease very poor. Currently, there no generally effective therapy available to treat CRAO. Hyperbaric oxygen (HBOT) can increase the volume delivered ischemic tissue until spontaneous or assisted reperfusion occurs. We report case a patient who experienced sudden visual loss due CRAO that was treated with HBOT. 81-year-old woman presented in her right eye (OD). She exhibited "hand...

All retinal photographs were graded using an international classification grading system. Osteoporosis assessed dual-energy x-ray absorptiometry. Multivariate...

We used deep learning to predict the final central foveal thickness (CFT), changes in CFT, best corrected visual acuity, and acuity following noncomplicated idiopathic epiretinal membrane surgery.Data of patients who underwent surgery at Severance Hospital from January 1, 2010, December 31, 2018, were reviewed. Patient age, sex, hypertension diabetes statuses, preoperative optical coherence tomography scans noted. For image analysis model development, a pre-trained VGG16 was adopted. The...

However, there have been no reports on prevalence PIMs prescriptions according in South Korea. Methods: This is a retrospective study using medical records and code analysis each PIM survey common used for elderly patients. Locating was carried out all outpatients who visited Asan...

This study was performed to evaluate the efficacy of using a thin bronchoscope for diagnosis pulmonary tuberculosis (PTB).Between March 2019 and November 2021, we prospectively enrolled participants with suspected PTB whose sputum acid-fast bacilli (AFB) smear (TB) polymerase chain reaction (PCR) tests were negative or who could not produce self-expectorated sputum. Participants randomized control group (bronchial washing [BW] 5.9-mm conventional guided by chest computed tomography) an...

Purpose: To analyze the association of visual efficiency and quality life using data from fifth Korea National Health Nutrition Examination Survey (KNHANES V). Methods: The present study included 5,244 glaucoma or suspect subjects who completed a acuity test, field test health-related questionnaire KNHANES V. Visual was calculated best corrected test. Quality assessed with EuroQoL 5D (EQ-5D). compared vision better eye to evaluate relationship life. One-way analysis variance (ANOVA) partial...

To investigate the association between regional solar radiation and myopia occurrence in South Korean children. A population-based cross-sectional study using data of 1218 children aged 7-9 years from Korea National Health Nutritional Examination Survey was conducted January 1, 2008, to December 31, 2012.
