Cycloscopy and fluorescein cycloscopy.

A biomicroscopic technique for observation of the ciliary process was developed, and cycloscopy and fluorescein cycloscopy have been done as a routine clinical examination. The observations reported here show that a great, previously unimaginable variety of changes in the ciliary process is the usual sequel of congenital or acquired disorders. Fluorescein was seen to leak mainly from the "summit" of the ciliary process in the normal eye. Little or no leakage from the rudimentary ciliary process was seen in cases of aniridia, while vigorous leakage occurring in inflammation or uveal effusion was of particular clinical importance.
