TRANSPARENT AND REVERSIBLY HEAT-GELLING AQUEOUS COMPOSITIONS

摘要

A reversibly heat-gelling aqueous composition containing methyl cellulose preferably together with at least one member selected from the group consisting of hydroxypropylmethycellulose, polyethylene glycol, oxyacids and pharmaceutically acceptable salts thereof, amino acids and pharmaceutically acceptable salts thereof and urea, and an artificial vitreous body using the same. The above composition makes it possible to provide an ideal artificial vitreous body which is little toxic to ocular tissues and aseptic, can be easily injected and withdrawn, gels at the body temperature, facilitates the observation of eyegrounds because of being transparent and is expected as exerting the tamponade effect.
