PURPOSE: To investigate the incidence and risk factors of cystoid macular edema (CME) after silicone oil (SO) injection for retinal detachment. METHODS: Fifty-eight patients with retinal detachment treated by vitrectomy with SO tamponade during 2011 to 2015 were retrospectively assigned to CME and non-CME groups. Patients underwent complete ophthalmological examination, including color fundus photography and preoperative and postoperative optical coherence tomography...

PURPOSE: To design software with a novel algorithm, which analyzes the tortuosity and vascular dilatation in fundal images of retinopathy of prematurity (ROP) patients with an acceptable accuracy for detecting plus disease. METHODS: Eighty-seven well-focused fundal images taken with RetCam were classified to three groups of plus, non-plus, and pre-plus by agreement between three ROP experts. Automated algorithms in this study were designed based on two methods: the curvature measure and distance transform for assessment of tortuosity and vascular dilatation, respectively as two major parameters of plus disease detection...

PURPOSE: Age-related eye disease is often considered part of natural aging. Lack of awareness of eye conditions can result in missed treatment. We investigated the rates of awareness of cataract and age-related macular degeneration, the most common age-related eye-diseases, and the associated factors among elderly Koreans. METHODS: We identified 7,403 study subjects (≥40 years old) with cataract or age-related macular degeneration based on ophthalmic examination results during the 5th Korean National Health and Nutrition Examination Survey conducted between 2010 and 2012...

PURPOSE: To compare the retinal nerve fiber layer (RNFL) as well as the macula volume and thickness in the eyes of age-matched healthy controls with no cognitive disabilities with those of elderly people with mild cognitive impairment (MCI) or Alzheimer disease (AD). We used optical coherence tomography (OCT) to determine the effectiveness of the above quantities for early diagnosis of MCI or AD. METHODS: Ninety eyes were considered in this study, split between 30 normal eyes, 30 eyes from patients with MCI, and 30eyes from patients with AD...

PURPOSE: To evaluate the long-term efficacy and safety of intracameral bevacizumab in patients with neovascular glaucoma. METHODS: This retrospective study included 26 eyes of 26 neovascular glaucoma patients who received intracameral bevacizumab injection between January 2013 and May 2015, and were followed-up for at least 1 year. All patients were treated with topical and/or systemic intraocular pressure (IOP)-lowering medications, intracameral bevacizumab, and panretinal photocoagulation (PRP)...

PURPOSE: To investigate the prevalence and risk factors for an epiretinal membrane (ERM) in Korean population. METHODS: Using the database of the Korea National Health and Nutrition Examination Survey from 2008 through 2012, 14,772 participants 40 years of age or older with gradable fundus photographs were included. The presence of ERM was determined by using fundus photographs. The prevalence of ERM was estimated and possible risk factors including systemic factors, nutritional status, and blood tests were analyzed via multiple logistic regression analyses...

Jang Hoon Lee, Sung Pyo Park, Yong Kyu Kim
PURPOSE: To evaluate the association between degree of retinal abnormalities and uncorrected visual acuity (UCVA) in idiopathic epiretinal membrane (ERM) patients with a small amount of refractive error. METHODS: We retrospectively reviewed 49 eyes (37 patients) of idiopathic ERM patients. We investigated the association between visual acuity and macular status (central macular thickness [CMT], outer retinal integrity score, and inner retinal irregularity index) that was assessed by optical coherence tomography using multiple linear regression analysis...

Ji Soo Shin, Young Hoon Lee
PURPOSE: The aim of this study was to evaluate the changes in thickness of each macular retinal layer, the peripapillary retinal nerve fiber layer (RNFL), and central macular thickness (CMT) after 577-nm pattern scanning laser (PASCAL) photocoagulation in patients with diabetic retinopathy. METHODS: This retrospective study included 33 eyes with diabetic retinopathy that underwent 577-nm PASCAL photocoagulation. Each retinal layer thickness, peripapillary RNFL thickness, and CMT were measured by spectral-domain optical coherence tomography before 577-nm PASCAL photocoagulation, as well as at 1, 6, and 12 months after 577-nm PASCAL photocoagulation...

PURPOSE: To compare and analyze changes in vision quality, subjective symptoms, and psycho-social satisfaction in keratoconus and myopic patients following the wearing of contact lenses. METHODS: This study enrolled 25 keratoconus and 25 myopic patients with corrected vision over 0.8 according to the Snellen chart due to treatment with contact lenses. Patients were surveyed prior to the wearing of contact lenses, and again after three months of contact lens usage with a questionnaire about quality of vision and life...

PURPOSE: To investigate the peripapillary choroidal thickness (PCT) of polypoidal choroidal vasculopathy (PCV) and exudative age-related macular degeneration (AMD) and to evaluate their responses to anti-vascular endothelial growth factor (VEGF). METHODS: Thirty eyes with PCV and 25 eyes with exudative AMD who were treatment naïve were included in this study. PCT and subfoveal choroidal thickness were evaluated both before and after intravitreal anti-VEGF. RESULTS: The initial mean PCT of PCV (153...

PURPOSE: To evaluate the classification of punctal stenosis based on the shape of the external punctum, clinical characteristics and histopathologic features. METHODS: Patients who experienced tearing and were diagnosed with punctal stenosis were evaluated in this study. Punctal stenosis was classified according to the shape of the lower external punctum, which included membranous type, slit type, horseshoe type, and pinpoint type. Tear meniscus height, 2% fluorescein dye disappearance test and lacrimal pathway irrigation were measured or performed...

PURPOSE: In the present study, the visual discomfort induced by smart mobile devices was assessed in normal and healthy adults. METHODS: Fifty-nine volunteers (age, 38.16 ± 10.23 years; male : female = 19 : 40) were exposed to tablet computer screen stimuli (iPad Air, Apple Inc.) for 1 hour. Participants watched a movie or played a computer game on the tablet computer.
