The Use Of Computer Link With Eye Desease

Heavy computer use could be linked to glaucoma, especially among those who are short-sighted, fear researchers. Glaucoma is caused by increased fluid pressure within the eye compressing the nerves in the rear, which can lead to blindness if left untreated.

Glaucoma can be treated
The results, published in the Journal of Epidemiology and Community Health, are based on 10000 Japanese workers. The authors and experts recommend more research, especially because it is short-sighted is a known risk of glaucoma.

Eye strain Dr Masayuki Tatemichi, Toho University School of Medicine and his colleagues tested the hearing of workers in four Japanese companies, employing more than 5000 people each. Employees were asked to complete questionnaires about their computer use, both at home and at work, and any history of eye diseases. Researchers are divided workers depending on how often you use a computer, labelling them by the user's works in computer.

It will be important to follow this study with further research. David Wright, executive director of the Association of International Glaucoma The use of computers are classified into four blocks of five years, ranging from less than five years over 20 years, as well as four blocks away from the average amount of time spent on the screen at each session, ranging from less than an hour to more than eight hours at a time.



The classified of the most heavy computer users tended to be men and boys. In total, 522 (5.1%) of workers found that the anomalies of the visual field. Workers who were classified as heavy computer users were more likely to always be forward-looking (hyperopia) or myopic (myopia). About one third (165) of these workers had suspected glaucoma. After further analysis, the use of heavy equipment, suspected glaucoma and myopia seems to be interrelated.



We do not know why this might be, but we believe it could be that short-sighted people are more susceptible to computer-related eye strain. Glaucoma is the leading cause of irreversible blindness worldwide, affecting more than 500 thousands people in the UK alone. Aggravated by the fact that more and more people are using computers, researchers said: "In the next decade, therefore, could be important for public health professionals to show more concern about myopia and anomalies visual field in heavy computer users. "



More research But they said they needed to confirm their findings because the study included mainly men and refractive errors (which indicate how long or short-sighted is someone) is not officially measured. Nick Astbury, president of the UK's Royal College of Ophthalmologists, noted that the Japanese population had a high prevalence of myopia and anyway that myopia is a known risk factor for glaucoma. "I doubt that looking at the computer makes no difference," he said.



David Wright, executive director of the Association of International Glaucoma, said: "There may be a risk in the intensive use of computer hardware. "It would be prudent for all those involved in this kind of heavy use to ensure that they receive regular comprehensive eye examinations to detect as soon as possible signs of developing glaucoma, when treatment is most effective." He said that the eyes of three tests must be conducted to see if glaucoma: ophthalmoscopy (a visual examination of the papilla), tonometry (a measurement of pressure in the eye) and perimetry (which controls the visual field abnormalities ). "It will be important to follow this study with further research in other ethnic populations in order to establish the full validity of this first indication of a possible problem and also to address the ethnic composition of the risk factors should add to the test The Japanese report, said.
