Abstract:

Introduction: The eye injuries inflicted in different sport activities are relatively rare and depend upon the type of sport. They are more common in recreational sport activities. These injuries are generally minor but may be very severe and result in permanent vision impairment. One must be aware of the fact that these sport activities, either recreative or professional, are exercised by young people. Methods: All analyzed patients were hospitalized at the Clinic of Eye Diseases, Clinical Center of Serbia, Belgrade, for severe eye injuries which occurred in sport activities. The analyzed period included 10 years, from the beginning of 2000 to the end of 2009. Results: In this period, a total of 117 patients with eye injuries sustained in some of sport activities were hospitalized. There were 114 (97.5%) injured males. Mean age of the injured was 25.8 years, and there were no individuals older than 50 years of age. Closed eyeball injures were reported in 96.6% and open injuries were seen in the remaining 3.4% of cases. During recreational sports, the eye injuries occurred in 76.1%, in the school19.6%, and in professional sport—4.3% of the time. The injured individuals were as follows: pupils—35.0%, students—17.9%, workers—22.2%, clerks—20.6% and professional players—4.3% of cases. Upon completed treatment, visual acuity was normal in 77.8%, subnormal in 16.2%, impaired in 3.4% and amaurosis in 2.6% of

Abstract: marcus gunn phenomenon is a congenital movement associated with the trigeminus-oculomotor nerve which affects the levator palpebrae superioris and the mastication muscles. ptosis associated with synkinesis is presented and it consists of the involuntary synchronic (ptosis) eyelid elevation, related to the movements of lateral displacement of the jaw or when opening the mouth, which is frequently found in girls in left eye; occasionally rectus superioris paralysis of left side is also observed. it is rarely associated with systemic anomalies. some authors consider that this phenomenon is less evident as the years pass. the ophthalmologic and clinical features of a patient that was diagnosed with this syndrome in association with systemic anomalies is presented. the early diagnosis of this pathology makes the prevention of amblyopia and its sequela possible.

Advances in Infectious Diseases (AID) , 2018, DOI: 10.4236/aid.2018.82008
Abstract: Analysis of eye diseases of patients at Kasungu District Hospital in Malawi was made. Malawi is one of the poorest countries in the world and the health system faces a lot challenges in terms of resources. The study was, therefore, done to understand the burden and distribution of eye diseases in this resource-limited setting. A retrospective study was conducted by extracting data from data registers in the outpatient eye department for the period of May 2015 to June 2016. The data of the reported eye diseases analyzed with variables such as patient gender, eye disease type, patient age and times of the year. There was no association between eye diseases and gender nor with times of the year. However, it was noted that the commonest type of eye disease was conjunctivitis. And, there was strong association of some disease type with age, for example, conjunctivitis was common in young age group while cataract was common in the elderly. It was shown in this study that many of the eye diseases endemic in Africa do generally occur in this selected district as well. However, the analysis presents the possibility of reducing the incidences of many diseases by preventive measures and access to health facilities on time.

Brain initiated interaction  [PDF]
Rajesh Singla, Balraj Gupta
Journal of Biomedical Science and Engineering (JBiSE) , 2008, DOI: 10.4236/jbise.2008.13028
Abstract: Brain-Computer Interfaces (BCI) are developed to help locked-in patients, who lose control of their bodies and are unable to perform simple tasks such as speech, locomotion, and can’t even effectively interact, with their environment. BCI shows promise in allowing these individuals to interact with a computer using EEG. A Brain Computer Interface is a communication system in which messages or commands that an indi-vidual sends to the external world do not pass through the brain’s normal output pathways of peripheral nerves and muscles. A system is created to allow individuals with motor disabili-ties to control the motion of the bed on which they are bedridden via BCI for drug delivery and other activities, with the help of eye motion and changes in the absolute power in alpha rhythms of an EEG signal of the patient.
Comparison of SVM and ANN for classification of eye events in EEG  [PDF]
Rajesh Singla, Brijil Chambayil, Arun Khosla, Jayashree Santosh
Journal of Biomedical Science and Engineering (JBiSE) , 2011, DOI: 10.4236/jbise.2011.41008
Abstract: The eye events (eye blink, eyes close and eyes open) are usually considered as biological artifacts in the electroencephalographic (EEG) signal. One can con-trol his or her eye blink by proper training and hence can be used as a control signal in Brain Computer Interface (BCI) applications. Support vector ma-chines (SVM) in recent years proved to be the best classification tool. A comparison of SVM with the Artificial Neural Network (ANN) always provides fruitful results. A one-against-all SVM and a multi-layer ANN is trained to detect the eye events. A com-parison of both is made in this paper.
Eye Tracking During High Speed Navigation at Sea  [PDF]

Journal of Transportation Technologies (JTTs) , 2012, DOI: 10.4236/jtts.2012.23030
Abstract: Purpose: Professional high speed sea navigational procedures are based on turn points, courses, dangers and steering cues in the environment. Since navigational aids have become less expensive and due to the fact that electronic sea charts can be integrated with both radar and transponder information, it may be assumed that traditional navigation by using paper based charts and radar will play a less significant role in the future, especially among less experienced navigators. Possible navigational differences between experienced and non-experienced boat drivers is thus of interest with regards to their use of navigational aids. It may be assumed that less experienced navigators rely too much on the information given by the electronic sea chart, despite the fact that it is based on GPS information that can be questioned, especially in littoral waters close to land. Method: This eye tracking study investigates gaze behaviour from 16 ex perienced and novice boat drivers during high speed navigation at sea. Results: The results show that the novice drivers look at objects that are close to themselves, like instrumentation, while the experienced look more at objects far away from the boat. This is in accordance with previous research on car drivers. Further, novice boat drivers used the electronic navigational aids to a larger extent than the experienced, especially during high speed conditions. The experienced drivers focused much of their attention on objects outside the boat. Conclusions: The findings verify that novice boat drivers tend to rely on electronic navigational aids. Experienced drivers presumably use the navigational aids to verify what they have observed in the surrounding environment and further use the paper based sea chart to a larger extent than the novice drivers.
Eye Blink Responses to the Four Basic Taste Stimuli in Healthy Young Humans  [PDF]

Journal of Behavioral and Brain Science (JBBS) , 2013, DOI: 10.4236/jbbs.2013.34038
Abstract: Taste stimuli can elicit facial responses, and the facial responses may be useful indexes of taste sensations. In this study, we propose that eye blinking is also elicited by taste stimuli and we examined eye blink responses in six healthy young adults. Low and high concentration solutions of the four basic taste qualities (sweetness, saltiness, sourness, and bitterness) and distilled water were delivered via a silicone tube. Facial responses were recorded by a video camera and eye blink responses were identified. The number of eye blinks in the 5 s following stimulation, and the latency and duration of the first eye blink, were quantified. High concentrations of sour and bitter solutions increased the number of eye blinks (195% and 227%, respectively; P < 0.01), and shortened the latency (68% and 62%; P < 0.05) and prolonged the duration (188% and 184%; P < 0.05) of the first eye blink compared to distilled water. Eye blink responses may be due to a gustofacial reflex and/or a myotatic reflex within the facial muscles. These results suggest that the eye blink response can be used as an index of gustofacial response.
