Microfilm Storing Technique in Electronystagmography: Two Years of Experience

At the Regional Hospital, Orebro, Sweden. an EEG routine was established 4 years ago including ADB and integrated microfilm technique. Two years ago the microfilm technique was also applied to the: ENG routine, 3 M microfilm cards being used for storing records and typewritten data. Information is regained by means of a microfilm reader apparatus or a microfilm projector; paper copies may also be made. The microfilm technique permits much easier and more rapid examination of previous records compared with the original paper diagram evaluation. This is important in the daily handling of the ENGs, especially when estimating possible progress or regression in the course of various vestibulary diseases. The microfilm method also has reduced storing space requirements to a minimum.
