Prosthetic reduction of upper eyelid ptosis.

It is important that an ocularist be knowledgeable of the five types of anophthalmic ptosis, their causes and most effective treatment method. In earlier days ocularists had only one method of correcting this problem. With the advent of plastic material several more were invented, but none were totally effective or comfortable for the patient. This chapter describes the five types of ptoses, some simpler methods for correction with prostheses, but emphasizes a complex method initiated in the early 1950s by Lee Allen. It has been used by many other ocularists since. A description of the method and its effectiveness is discussed.
