Abstract |
Chondroitin sulfate (CS) in corneal preservation medium can porolong corneal preservation time. The solutions used in the experimental chambers were made of TC-199 (GIB Co.) either by itself of by adding 1% CS (Sigma) to the TC-199. The evaliation of the viability of corneas can be made by monitoring their physiological parameter. Thus, we monitored the transendothelial electrical potential difference (p.d.) across deepithelialized rabbit corneas. We found that TC-199 containing 1% CS maintained higher p.d.'s than the same solution without CS. |
