In Korea there is an old saying: The eye is the pearl of the face. Considering the fact that over 80 percent of information necessary for man is the image information obtained through vision, the saying is not an exaggerated expression. This is why it is regarded as important today to put eye treatment on a more scientific footing and further improve its clinical and practical efficacy before any other part of the body.
The Pyongyang Medical College of Kim Il Sung University has intensified inquiries to apply a cutting-edge technique to eye treatment and finally developed a new visual electrophysiologic testing instrument. The core of this latest medical instrument, which measures bioelectric potential originating from the optic nerve system and diagnoses eye diseases according to the measured value, is the bioelectric potential amplifier.
On the basis of the principle that optic nerve cells cause different electric potential value when they are exposed to photic simulation, and that electric potential values differ at each foceus, the members of the research team confirmed electric potential values suited to the constitutional peculiarity of the Koreans. And they also made it possible to magnify minute bioelectric potential 10 000 times by using the electromyography similar to bioelectric potential amplifier. As a result, relevant diagnoses, which were previously given by the subjective examination of doctors as there was no quantitative measured index can be done on a throughly scientific footing.
This testing instrument can discriminate between the normal and the abnormal from characteristic values and detect eye diseases which have the same symptoms as those revealed by macroscopic examination. In particular, it can diagnose exactly retinal diseases like retinitis pigmentosa and diabetic retinopathy and other eye diseases with different symptoms such as ocular movement disorder and optic nerve disease. Today the relevant patients say in admiration that the instrument is a marvellous one which can find out quickly the cause of diseases which it was hard to decide how to treat, and that it is a treasure machine making it possible to treat with eye drops the diseases which was recognized by macroscopic diagnosis had to be treated through operation.
Jon Yong Guk, a department head of the teaching hospital, said on the secret of their success, “The combination of insight into the world and self-development helped the patients recover from eye diseases, and e nabled us to diagnose eye diseases”.
The instrument is very accurate in analysis as it causes less clutter, and in particular, it costs one tenth of those of the previous equipment, so it is considered to be widely used in the future.
