[Disorders of binocular vision in amblyopic patients working at computer terminals].

For the first time two cases are described with disturbances of binocular vision caused by subjective perception of positive scotomata in the amblyopic eye. The visual strain of working at a terminal leads to a slight increase in the squint angle; as a result, a paracentral scotoma may shift into the middle of the binocular visual field and impair the image quality of the fixing eye. Amblyopic subjects presenting with these symptoms are disqualified from working at VDUs. However, not every amblyopic is affected.
