[The so-called bridle operation].

In two cases of palsy of the third nerve we found a paresis of two neighboring rectus muscles without cyclotropia (i.e., palsy of the medial rectus muscle an the superior rectus muscle). In these cases, we performed a new procedure, which consists in transpositing the two functioning rectus muscles at the insertion of the two paretic muscles. The effect is greater if the transposed muscles are linked with fascia lata behind the globe, as performed in the second case.
