Effect of lens extraction in pseudoexfoliation of the lens capsule.

It is a matter of considerable clinical interest whether removal of the lens causes regression of pseudoexfoliation of the lens capsule. Before the paper by Dvorak-Theobald (I954), pseudoexfoliation of the lens capsule was often confused with true exfoliation, and it was suggested that lens extraction caused the condition to disappear (Irvine, I940; Gradle and Sugar, I947). After this paper app...

Trabeculotomy in pseudoexfoliation of the lens capsule.

Trabeculotomy was performed on 12 eyes of 11 patients with glaucoma associated with pseudoexfoliation of the lens capsule. Pressure was lowered in all eyes, in 10 eyes to 15 mmHg or less, 7 with no medication but 3 with medication. A subconjunctival bleb was present in 5 patients but was not necessary for a good result. These results suggest that the raised intraocular pressure which often occu...

Characterizing molecular diffusion in the lens capsule.

The lens capsule compartmentalizes the cells of the avascular lens from other ocular tissues. Small molecules required for lens cell metabolism, such as glucose, salts, and waste products, freely pass through the capsule. However, the lens capsule is selectively permeable to proteins such as growth hormones and substrate carriers which are required for proper lens growth and development. We use...

Extraction of the Lens in Its Capsule

to the operation the patient is too much meddled with. After the usual dark-room examination the pa'.ient is put to bed, given a purge, the eye lashes and eye-briow shaved, an antiseptic dressing applied the night before operation. A weak solution of cocaine is used for the operation and several drops are put in the eye at intervals of ten mfinutes before the operation. The patient .is then bro...
