A new method for head posture and gaze direction estimation is proposed. Firstly, three models of head position are established and postures are judged based on triangle attribute constituted by eyes and mouth. Then pupil is located using Hough transform in eye area. With the method of horizontal and vertical projection and eye prior knowledge, the normal eye outline is fitted. Finally, gaze di...

Abstract Background and Aims: Cytomegalovirus (CMV) infection is very common in the population. Virus belongs to the family Herpesviridae, whose representatives are characterized by the ability to cause the human body's latent persistent infections. The goal of the study is to assess the CMVV infection frequency and PCR method in the choice of CMV in inflammatory eye disease, Comparing wit...

Eyes absent (Eya) is a highly conserved transcription cofactor and protein phosphatase that plays an essential role in eye development and survival in Drosophila. Ectopic eye induction assays using cDNA transgenes have suggested that mitogen activated protein kinase (MAPK) activates Eya by phosphorylating it on two consensus target sites, S402 and S407, and that this activation potentiates the ...

Most of our visual experience is driven by the eye movements we produce while we fixate our gaze. In a sense, our visual system thus has a built-in contradiction: when we direct our gaze at an object of interest, our eyes are never still. Therefore the perception, physiology, and computational modeling of fixational eye movements is critical to our understanding of vision in general, and also t...

Volume 90, Number 11 www.aafp.org/afp American Family Physician 791 A 42-year-old woman presented with gradually decreasing vision in her right eye that began five days earlier. She did not have chest pain, palpitations, headache, or other neurologic symptoms. She was taking lisinopril (Zestril), furosemide (Lasix), and carvedilol (Coreg) and had allergies to atenolol (Tenormin), hydrochlorothi...

The case is a 2-year-old previously healthy girl with coincidental penetrating eye and brain injury. A metal rod was inserted into the skull through the upper border of the right globe. After admission and diagnostic and surgical approaches, the rod was removed under general anesthesia, and no brain hematoma or ocular and significant periocular injuries were detected. No neurologic and ophthalm...

PURPOSE The Ocular Protection Index (OPI) 2.0 System was developed to evaluate ocular surface protection under a natural blink pattern and normal visual conditions. The OPI 2.0 System implements fully automated software algorithms which provide a real-time measurement of corneal exposure (breakup area) for each interblink interval during a 1-minute video. Utilizing this method, the mean breakup...
