Structural changes Vitreous body There is a significant structural change during aging‚ consisting of a transition from a clear gel in young to a fibrous structure in adults. In old age there is advanced liquefaction with thickening and tortuosity of vitreous fibers‚ and collapse (syneresis) of vitreous (Fig. 2.3). Postmortem studies80 found syneresis in 70% of subjects in the eighth decade. Syneresis occurs earlier and is more extensive in myopic eyes‚81 and is accelerated with inflammation‚ trauma

Enzymes lower the activation energy of chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH’s. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction. Alpha amylase converts starch into glucose and when starch is combined with I2KI indicator a dark purple solution forms. As the enzyme breaks down the starch the absorbency will decrease. The absorbency
