PHPV – PERSITENT HYPERPLASTIC
PRIMARY VITREOUS
The mode of inheritance of PHPV
is not so clear, but it is known
that it is a congenital
condition (present at birth) and
that it is not progressive. This
means that if a puppy is born
with PHPV it can be detected by
ophthalmic screening from 6
weeks of age and if it is
affected, whatever the condition
of the problem at that stage it
will not change throughout the
dogs life.
Either of the above conditions
can be operated on, but it is a
serious operation and can be
traumatic and very expensive. It
is not always covered by
insurance due to the hereditary
nature.
Even though the genetic test is
now available for Hereditary
Cataracts it is still important
to screen for PHPV.
