Since Burian1 demonstrated that images falling on peripheral portions of the retinae could elicit fusional movements, some interest has been generated in this subject. The value of such a mechanism to the orthoptist has been suggested by a number of investigations2,3,6 of fusional movements in patients having small angles of tropia. If techniques that utilize peripheral fusion are to be applied, it is desirable that its parameters be studied in the normal subject. This investigation represents an attempt to initiate a study of the parameter of retinal locus.
Burian1 was able to demonstrate that peripheral fusion stimuli could cause disruption of central fusion. Winkelman7 used this phenomenon in his studies on peripheral fusion. Lyle and Foley3 were also able to show this, but they were unable to elicit central diplopia in the majority of their 50 subjects and found it to be transient in those
