New study illuminates links between vision and neck complaints

24.06.2005


Can vision problems cause musculo-skeletal complaints and vice versa? This is a key question for anyone who works in front of a computer screen every day. Together with research colleagues at the Karolinska Institute, Uppsala University, and in the U.S., Associate Professor Hans O. Richter at Gävle University College has recently shown that when the tone is reduced in the focusing muscle of the eye, nerve impulses to the neck and shoulders are also affected. Now the team wants to go on to investigate the connection between eye problems and neck and back complaints in a cross-disciplinary study.



Today more than 60 million people in the EU work with computers. Many of them experience vision problems in connection with computer-screen work, including eye fatigue, eye pain, a gravely feeling in the eyes, stinging, bloodshot eyes, a feeling of dryness, temporary functional near-sightedness, often together with headaches and pains in the neck and/or shoulders. Mapping what causes these work-environment problems is a major issue for international organizations like ILO and WHO.

Focusing the lens of the eye requires coordination between various nerve and muscle groups in the eye, neck, and shoulder region. The connection between these causal factors has now been studied by a research team from Gävle University College, Uppsala University, the Karolinska Institute, and the University of Minnesota. The findings of the most recent part of the study, now being published in an international scientific journal, show that reducing the tone of the focusing muscle (by placing an optical lens over the eye and at the same time seeing to it that the lack of focus incurred is compensated for by relaxing the accommodation) affects (deactivates) the section of the cerebral cortex that regulates muscular movement in the head, neck, and shoulder region. The experiments were carried out using a PET camera (Positron Emission Tomography), where radioactive marker substances are used to monitor the activity in the brain of volunteers who were asked to focus the lens of their eyes on different types of stimuli under varying optical conditions.


Questions raised by the findings of the study are whether eye problems can cause stiffness, muscle aches, etc. in the neck/cervix and shoulder region. The reverse­-whether complaints in muscles and joints in the neck/cervix and shoulder region can affect the ability of the eye to focus­-should also be investigated further, according to research director Hans Richter:

’It is vital to seek further knowledge of how tensing and relaxing the neck, throat, and shoulders affects the eyes and how eye complaints can trigger and/or aggravate muscular aches in the shoulders and/or neck region. The findings may show, for instance, that patients who experience back and neck pain working with computers should have their eyes examined,’ Hans Richter maintains.

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
