Effect of low-level light therapy in patients with dry eye: a prospective, randomized, observer-masked trial.

To evaluate the efficacy of low-level light therapy (LLLT) with near-infrared light-emitting diodes (LED-LLLT) for the treatment of dry eye. 40 patients were randomly assigned with a 1:1 allocation ratio to receive LED-LLLT (LLLT group, n = 20) or placebo treatment (placebo group, n = 20). Patients in the LLLT group received LLLT twice a week for 3 weeks, for a total of 6 treatment sessions.

Posterior segment complications of Ahmed valve implantation.

Background: To assess the time, incidence, and outcome of posterior segment complications of Ahmed valve implantation (AVI).

Methods: 248 eyes that underwent AVI were reviewed retrospectively. Visual acuity, preoperative characteristics, and postoperative posterior segment complications were assessed.

Explainable Machine Learning Model for Glaucoma Diagnosis and Its Interpretation.

The aim is to develop a machine learning prediction model for the diagnosis of glaucoma and an explanation system for a specific prediction. Clinical data of the patients based on a visual field test, a retinal nerve fiber layer optical coherence tomography (RNFL OCT) test, a general examination including an intraocular pressure (IOP) measurement, and fundus photography were provided for the feature selection process. Five selected features (variables) were used to develop a machine learning prediction model.

Comparative study on the effect of hyperthermic massage and mechanical squeezing in the patients with mild and severe meibomian gland dysfunction: An interventional case series.

Background: Meibomian glands exist beneath the palpebral conjunctiva; thus, it is invisible to the naked eye without infrared imaging. This study used meibography to group patients with meibomian gland dysfunction (MGD) and assessed the effects of hyperthermic massage and mechanical squeezing in both groups.

Materials And Methods: Patients with MGD were divided into two groups, according to the degree of meibomian gland loss: group 1, in which the sum of eyelid scores ranged from 0 to 4 (mild to moderate gland loss) and group 2, in which the sum of eyelid scores ranged from 5 to 6 (severe gland loss).

Outcome of phacoemulsification in patients with open-angle glaucoma after selective laser trabeculoplasty.

Purpose: To investigate the outcome of phacoemulsification in selective laser trabeculoplasty (SLT)-treated eyes.

Methods: This retrospective study included patients who had open angle glaucoma (OAG) with previous SLT who underwent phacoemulsification. We evaluated intraocular pressure (IOP), length of glaucoma control without treatment, and antiglaucoma medication or surgery.

Comparison of peripapillary and macular choroidal thickness and ganglion cell complex thickness in glaucomatous and healthy eyes.

Aim: To assess choroidal thickness (CT) and its association with ganglion cell-inner plexiform layer thickness (GCIPLT) and retinal nerve fiber layer thickness (RNFLT) in open angle glaucoma (OAG) comparing with preperimetric glaucoma (PPG) and normal eyes.

Methods: Totally 55 eyes of OAG, 40 eyes of PPG, and 40 eyes of age-matched normal eyes were studied. Peripapillary CT (PCT), macular CT (MCT), RNFLT, and GCIPLT were evaluated.

Choroidal vascular index in patients with open angle glaucoma and preperimetric glaucoma.

Purpose: To evaluate choroidal structural changes in glaucoma using choroidal vascularity index (CVI) compared to healthy subjects.

Methods: This retrospective study included 56 patients with open angle glaucoma (OAG), 50 patients with preperimetric glaucoma (PPG) and 50 age-matched healthy eyes. Choroidal images were binarized into luminal area (LA) and stromal area.

A Randomized Multicenter Study Comparing 0.1%, 0.15%, and 0.3% Sodium Hyaluronate with 0.05% Cyclosporine in the Treatment of Dry Eye.

Purpose: To investigate the efficacy of 0.1%, 0.15%, and 0.

VITREORETINAL COMPLICATIONS AFTER PENETRATING KERATOPLASTY.

Purpose: To evaluate the time, incidence, and visual outcome of vitreoretinal complications after penetrating keratoplasty (PK).

Methods: A retrospective chart review of 1,594 eyes that underwent PK was conducted. Preoperative characteristics, visual significance, and postoperative vitreoretinal complications were analyzed.

Observation of Influence of Cataract Surgery on the Ocular Surface.

Introduction: To evaluate meibomian gland function, changes of lacrimal tears and ocular surface parameters and tear inflammatory mediators following cataract surgery.

Methods: 48 eyes of 34 patients who underwent uncomplicated phacoemulsification were involved and divided into 2 groups with those who had preexisting dry-eye before cataract surgery and those who did not. Ocular symptom score, Schirmer I test, tear film break-up time (TBUT), corneal sensitivity threshold, corneal staining, inflammatory cytokine activities, lid margin abnormalities, meibum expressibility, meibum quality and meibomian gland imaging were evaluated preoperatively, at 1 day, 1 and 2 months postoperatively.

The Relationship between Visual Impairment and Health-Related Quality of Life in Korean Adults: The Korea National Health and Nutrition Examination Survey (2008-2012).

Introduction: To evaluate health-related quality of life (HRQoL) in Korean adults with visual impairment(VI) using various measures based on a nationally distributed sample.

Methods: Using the Korea National Health and Nutrition Examination Survey (KNHANES, 2008-2012) data, we compared EuroQol five-dimensional questionnaire (EQ-5D) and EQ-visual analogue scale (VAS) scores after adjusting for socio-demographic and psychosocial factors as well as for comorbidities with VI. Logistic regressions were used to elucidate determinants for the lowest quintile HRQoL scales according to VI severity.

Acute endophthalmitis after intravitreal injection and preventive effect of preoperative topical antibiotics.

Purpose: To evaluate the incidence, causative organism, clinical features, and visual outcome of acute endophthalmitis following intravitreal injection and to report the clinical outcome of patients receiving preinjection antibiotics for the prevention of endophthalmitis.

Methods: For all intravitreal triamcinolone acetonide, bevacizumab, ranibizumab, and C3F8 gas injections performed in our outpatient clinic between June 2008 and November 2012, the number of injections, indications, types of administered drugs, and methods of injection were investigated. A retrospective chart review was performed comparing patients with self-administration of antibiotic eye drops for 3 days before injection (n=8649 injections), and patients those who received no pretreatment with antibiotics (n=8683 injections).
