In 1936 Dickey1 described a new operation for ptosis which, he claimed, offered certain advantages over operations of the Motais type. His indication for the operation was the presence of complete ptosis associated with normal function of the superior rectus muscle. In such cases ptosis operations on the levator muscle by the Blaskovicz method are usually disappointing, and either the Motais or some method of attaching the lid to the frontalis muscle is customarily employed. The disadvantages of operations of the latter type are well known, the chief of these being failure of the lid to follow the cornea in looking down, so that an area of sclera is exposed. Hence these operations should probably be reserved for cases of complete ptosis with no function of the superior rectus muscle.
The chief disadvantage of the Motais operation is the occasional detachment of the superior rectus slip from its new
