| Summary: |
Changes that occur in the
vitreous during ageing are reviewed in this article. The
events that are responsible for ageing changes can be
considered, according to Sebag, in three categories:
rheologic, biochemical, structural. Liquefaction within
the vitreous body along with the weakening of the
vitreous cortex-internal limiting lamina adhesion leads
to posterior vitreous detachment (PVD). As a result of
anomalous posterior vitreous detachment vitreoschisis,
retinal tears, and multiple floaters can occur. Patients
with PVD symptoms should be given a careful retinal
examination and be reexamined after few weeks. |
