Purpose To compare the anterior and posterior choroid thickness (ACT and PCT, respectively) in primary open-angle glaucoma (POAG), primary angle-closure disease (PACD), and healthy control subjects. Methods A total of 29 POAG patients (56 eyes), 37 PACD patients (64 eyes), and 34 healthy volunteers (68 eyes) were enrolled in this study; 50 POAG eyes were divided into 25 early/moderate-stage a...

This study investigated the topographic relationships among the eyeball and four orbital margins with the aim of identifying the correlation between orbital geometry and eyeball protrusion in Koreans. Three-dimensional (3D) volume rendering of the face was performed using serial computed-tomography images of 141 Koreans, and several landmarks on the bony orbit and the cornea were directly marke...

PURPOSE To investigate the nature of early ocular misalignments in human infants to determine whether they can provide insight into the etiology of esotropia and, in particular, to examine the correlates of misalignments. METHODS A remote haploscopic photorefraction system was used to measure accommodation and vergence in 146 infants between 0 and 12 months of age. Infants underwent photorefr...

PURPOSE To compare the efficacy of the subthreshold micropulse laser (SML) to conventional laser (CL) in treating focal leakages of the retinal pigment epithelium (RPE) in the eyes with central serous chorioretinopathy (CSC). METHODS Twenty-nine eyes of 28 patients with CSC and typical focal leakage were treated with CL or SML. Both treatments were made with a 577 nm yellow laser (CL: NIDEK M...

The spider genus Enna O. Pickard-Cambridge, 1897 comprises 38 species, distributed from Mexico to Southern Brazil, and is the most diverse genus of Trechaleidae (Platnick, 2013). Enna was revised by Silva et al. (2008) and 13 further species were described by Silva & Lise (2009a, 2009b), Carico & Silva (2010), Silva & Lise (2011) and Silva et al. (2012). Silva & Lise (2010) and Silva et al. (20...

The human eye-brain system is responsible for the highest percentage of sensory data from the environment. A major part of this system which is unique to all predator species (including man) is the ability to perceive distance of various objects using their two eyes. This is one of the primary reasons that man and other predators have both their eyes on the same side of their head (i.e. front) ...

Coronavirüsün (COVID-19) tüm dünyada eğitim üzerindeki zorunlu değişim ve kaçınılmaz etkileri ile birlikte uzaktan yaklaşımı ön plana çıkmıştır. Bu küresel salgın, eğitimin sekteye uğratılmadan devam ettirilmesi gerekliliğinin anlaşılmasıyla, eğitimde teknolojik alt yapıya daha fazla yatırım yapılması gerektiğini, kullanılan modelleri yaklaşımları yerine alternatif öğrenme yaklaşımlarına da öne...

PURPOSE To evaluate the efficacy, predictability, stability, safety, and complications of secondary anterior iris fixation of the Artisan iris-fixated intraocular lens (IOL) to correct aphakia in eyes without sufficient capsule support. SETTING Department of Ophthalmology, Jinling Hospital, School of Medicine, Nanjing University, Nanjing, China. DESIGN Cohort study. METHODS Eyes having im...

OBJECTIVE Determine the effects of display viewing distance on both the visual and musculoskeletal systems while the text height is held constant across viewing distances. BACKGROUND The distance from the eyes to a computer display may affect visual and neck comfort. If the angular size of the characters remains the same, it is recommended that the display be placed at a farther viewing dista...
