This report provides a detailed description of the methodology for ophthalmic examinations according to the Korea National Health and Nutrition Examination Survey ((KNHANES) Ⅶ & Ⅷ (from 2017 to 2021). The KNHANES is a nationwide survey which has been performed since 1998 in representatives of whole Korean population. During the KNHANES VII & VIII, in addition to the ophthalmic questionnaire, intraocular pressure (IOP) measurement, visual field test, auto refractometry, axial length and optical c...

Purpose To evaluate the real-world effectiveness, treatment patterns, and safety of ranibizumab in Korean patients with neovascular age-related macular degeneration (nAMD). Methods LUMINOUS™ is a 5-year, global, prospective, observational, open-label study. Adults aged ≥18 years who were either treatment-naive or prior-treated were enrolled and treated with ranibizumab 0.5 mg as per the local label. Outcome measures included mean (± standard deviation [SD]) changes from baseline in visual acuity...

PURPOSE To evaluate the functional and anatomical outcomes of a treat-and-extend (TAE) regimen with aflibercept for treatment-naive macular edema (ME) secondary to branch retinal vein occlusion (BRVO). METHODS This was a prospective, multicenter, noncomparative, open-label clinical trial. Forty-eight eyes of 48 patients received three monthly intravitreal aflibercept injections prior to the TAE regimen. However, if the best-corrected visual acuity (BCVA) was ≥ 20/20 and the central macular thick...

Non-rigid registration is a necessary but challenging task in medical imaging studies. Recently, unsupervised registration models have shown good performance, but they often require a large-scale training dataset and long training times. Therefore, in real world application where only dozens to hundreds of image pairs are available, existing models cannot be practically used. To address these limitations, we propose a novel unsupervised registration model which is integrated with a gradient-base...

BACKGROUND Ultra-widefiled (UWF) retinal images include significant distortion when they are projected onto a two-dimensional surface for viewing. Therefore, many clinical studies that require quantitative analysis of fundus images have used stereographic projection algorithm, three-dimensional fundus image was mapped to a two-dimensional stereographic plane by projecting all relevant pixels onto a plane through the equator of the eye. However, even with this impressive algorithm, refractive err...

AIMS To investigate the structure of multilayered pigment epithelial detachment (m-PED) in neovascular age-related macular degeneration, and its association with visual prognosis and the progression of fibrotic scars at 12 months. METHODS We retrospectively analysed 68 eyes of 63 patients with m-PED that included a prechoroidal cleft. The compartments within m-PED were divided into neovascular tissue (layer 1), a hyper-reflective band (layer 2), and a prechoroidal cleft (layer 3). Clinical varia...

Purpose To evaluate the one-year efficacy of intravitreal aflibercept injection in polypoidal choroidal vasculopathy (PCV) with best-corrected visual acuity (BCVA) of 20/40 or better. Methods This was a multicenter retrospective study. The medical records of patients diagnosed with treatment-naive PCV were retrospectively reviewed. Patients with an initial BCVA of 20/40 or better and who had undergone intravitreal aflibercept injection were included. Patients were treated with 3 consecutive mont...

Purpose To evaluate vortex vein engorgement and choroidal vascular hyperpermeability in patients with polypoidal choroidal vasculopathy (PCV) using ultra-widefield indocyanine green angiography (ICGA). Methods This retrospective case control study included 51 patients with unilateral PCV, 7 patients with bilateral PCV, and 43 age-matched controls. The number of quadrants of vortex vein engorgement was evaluated in the middle phase of ICGA, which was classified as extended engorgement if the dila...

BACKGROUND To investigate the effect of intravitreal dexamethasone implant (DEX implant) on hard exudate (HE) accompanying diabetic macular edema (DME). METHODS This study was a non-comparative non-randomized 1-year prospective interventional study. Patients with DME and HE were treated using DEX implant two or three times. Color fundus photography and optical coherence tomography (OCT) were performed at every visit. HE area was measured semi-automatically from the fundus photographs. RESULTS Th...
