PURPOSE: We compared the efficacy and safety of sodium hyaluronate (SH) and carboxymethylcellulose (CMC) in treating mild to moderate dry eye. METHODS: Sixty-seven patients with mild to moderate dry eye were enrolled in this prospective, randomized, blinded study. They were treated 6 times a day with preservative-free unit dose formula eyedrops containing 0.1% SH or 0.5% CMC for 8 weeks. Corneal and conjunctival staining with fluorescein, tear film breakup time, subjective symptoms, and adverse

BACKGROUND AND PURPOSE: We aimed to evaluate the lactate/albumin ratio (LAR) to identify its significance as a prognostic marker for favorable neurologic outcome and survival in patients with return of spontaneous circulation after out-of-hospital cardiac arrest (OHCA). Based on the LAR and multiple parameters, we developed new nomograms and externally validated the tools. METHODS: We conducted an observational study using a prospective, multicenter registry of out-of-cardiac arrest resuscitatio

PURPOSE: To evaluate changes in clinical outcomes, inflammatory cytokine levels, and tear osmolarity in the tears of patients with moderate to severe dry eye syndrome before and after the application of topical 1% methylprednisolone. MATERIALS AND METHODS: Thirty-two patients with moderate to severe dry eye unresponsive to previous aqueous enhancement therapy were enrolled. Five patients were lost to follow up, and twenty-seven patients were eligible for analysis. Patients were instructed to app

PURPOSE: The purpose of this study is to identify risk factors for severe thyroid-associated orbitopathy (TAO) and compressive optic neuropathy in Korean patients. METHODS: This study was a retrospective comparative case series. All TAO patients who were first seen at our institution between 2005 and 2009 and who had follow-up periods of at least 6 months were included. Patients were divided into mild or moderate and severe TAO groups. Cases were also segregated based on the presence or absence

PURPOSE: This study investigated factors associated with chorioretinal atrophy (CRA) progression in myopic choroidal neovascularization (CNV) after anti-vascular endothelial growth factor therapy. METHODS: Fifty eyes of 50 treatment-naive patients with myopic CNV who underwent anti-vascular endothelial growth factor monotherapy with at least 2 years of follow-up data were included. The cumulative occurrence of CRA progression was assessed using a Kaplan-Meier analysis. Demographic and clinical c

PURPOSE: To compare the short-term therapeutic efficacy of oral spironolactone treatment with that of half-dose photodynamic therapy (PDT) in patients with nonresolving central serous chorioretinopathy. METHODS: This retrospective, interventional, comparative study included 41 patients with nonresolving central serous chorioretinopathy who exhibited subretinal fluid accumulation for more than 3 months. Of the 41 patients, 18 (18 eyes) received oral spironolactone treatment and 23 (23 eyes) recei

Purpose: To evaluate changes in clinical outcomes, inflammatory cytokine levels, and tear osmolarity in the tears of patients with moderate to severe dry eye syndrome before and after the application of topical 1% methylprednisolone. Materials and Methods: Thirty-two patients with moderate to severe dry eye unresponsive to previous aqueous enhancement therapy were enrolled. Five patients were lost to follow up, and twenty-seven patients were eligible for analysis. Patients were instructed to app

Estrogen replacement therapy is a treatment to relieve the symptoms of menopause. Many studies suggest that natural bioactive ingredients from plants resemble estrogen in structure and biological functions and can relieve symptoms of menopause. The fruit of V. rotundifolia, called “Man HyungJa” in Korean, is a traditional medicine used to treat headache, migraine, eye pain, neuralgia, and premenstrual syndrome in Korea and China. The aim of the present study was to confirm that V. rotundifolia f

The clinical characteristics and profile of visual prognostic factors suggest an association between the severity of ocular inflammation and systemic disease.

Retinal hemorrhage is a frequently observed sign in Plasmodium falciparum infection. In Plasmodium vivax infection, however, retinal hemorrhage is very rare; only five cases have been reported in the literature. In this case report, we review the literature and the case of 52-year-old man who had retinal hemorrhages in P. vivax infection. We analyzed the structural characteristics of the lesions using fluorescein angiography and spectral-domain optical coherence tomography. Physicians should be

PURPOSE: To evaluate the efficacy of photodynamic therapy using a double dose of verteporfin for patients with circumscribed choroidal hemangioma. METHODS: This retrospective comparative case series evaluated data from 10 patients who were treated using double dose photodynamic therapy (12 mg/m) and seven patients who were treated using the standard dose (6 mg/m). A laser was applied with a radiant exposure of 50 J/cm. The ophthalmologic examinations were performed at baseline and 1 year after t

To evaluate the incidence and risk factors of contrast-induced nephropathy (CIN) in patients undergoing fluorescein angiography (FA). One hundred sixty patients who underwent FA as a part of ophthalmic examination and had serum creatinine (SCr) results within 24 h before FA and within 72 h after FA between 2005 and 2013 at a tertiary medical center were included. According to baseline SCr levels, the subjects were divided into low-risk group (<1.5 mg/dL), intermediate-risk group (1.5–2.0 mg/dL),

BACKGROUND: To evaluate therapeutic outcomes of interferon alpha-2a (IFNα2a) treatment in patients with Behcet's disease who were refractory to immunosuppressive agents. METHODS: This retrospective case series reviewed the medical records of 5 patients with refractory Behcet uveitis from January 2011 to February 2017. IFNα2a was administered at a dose of 3 million IU 3 times per week. Clinical response, relapse rate, and change of visual acuity were evaluated. RESULTS: The mean age of patients w

BACKGROUND: Drusen are important risk factor for neovascular age-related macular degeneration (AMD) and have a dynamic nature as they can enlarge, newly form, or disappear over time. There have been few reports on drusen regression or choroidal neovascularization (CNV) development after macular hole surgery. We report, to our knowledge, the first case of both drusen regression and subsequent CNV development within 7 months of successful macular hole surgery. CASE PRESENTATION: A 73-year-old woma
