BACKGROUND The purpose of this study was to evaluate the efficacy of a quantitative analysis method for comitant exotropia using video-oculography (VOG) with alternate cover. METHODS Thirty-four subjects with comitant exotropia were included. Two independent ophthalmologists measured the angle of ocular deviation using the alternate prism cover test (APCT). The video files and data of changes...

A new system is presented that enhances the interoperability between a video-oculographic (VOG) system for mouse movement control and an electromyographic (EMG) system for mouse click detection. The proposed VOG-EMG system combines gaze and muscle information to minimize the number of undesired clicks due to involuntary activations and environmental noise. We tested the system with 24 subjects,...

OBJECTIVES 1. To assess the reproducibility of eye movement velocity measurement using two methods: traditional electro-oculography (EOG) and infrared video-oculography (VOG) and, 2. Determine whether the normal values for unilateral weakness and bilateral reduction of caloric responses vary according to method employed. BACKGROUND Vestibular testing frequently involves measurement of eye mov...

Eruptive activity at the Kı̄lauea volcano (Hawai‘i, USA) has increased since 2008 resulting in volcanic air pollution (vog) at levels exceeding the national air quality standard for sulfur dioxide. Previous investigations during lower vog levels found adverse cardiorespiratory effects in the residents. The purpose of this 2012 survey was to reassess and compare the impact of the increased volcan...

Videooculography (VOG) is an eye movement measurement method used in the objective evaluation of vestibulo-ocular reflexes (VOR). An important requirement of VOG is to accurately estimate pupil center and ocular torsion, irrespective of drooping eyelids, eyelashes, corneal reflection, and blinking. Finding the accurate center of the pupil is particularly important in three-dimensional VOG, sinc...

We describe a novel, inexpensive method for real-time measurement of binocular three-dimensional eye position. The method employs consumer-grade digital video cameras ("webcams") to track an array of three fluorescent non-collinear markers affixed to each eye. The instantaneous position of the marker array relative to a reference position is used to construct a rotation matrix describing the ey...

OBJECTIVE To evaluate two cases of intermittent exotropia treated by vision therapy the efficacy of the treatment by complementing the clinical examination with a 3D videooculography to register and to evidence the potential applicability of this technology for such purpose. METHODS We report the binocular alignment changes occurring after vision therapy in a woman of 36 years with an intermi...

This research focuses on the addition of an ecological, sustainable material to improve durability earthen constructions and for use in rehabilitation restoration processes. Specifically, it studies mechanical waterproof performance mixture with a vegetal origin gel (VOG) obtained by extracting starch contained rice. solution increases behavior against water improves resistance system. study is...
