Two operative procedures are described by which the hitherto unmolested oblique ocular muscles can be reinserted according to the requirements of the abnormality. Torsion, depression, and abduction function can be increased or decreased as necessary. The operation on the superior oblique may be used for excessive elevation in adduction, and either advancement or recession of the superior rectus can be done conveniently along with advancement of the superior oblique. The operation on the inferior oblique is especially useful in depression of the globe accompanying ptosis and may in such cases be combined with advancement of the superior rectus.
