Phthisis Bulbi

                        --------------

                      General Information



The eye is composed of a number of parts.  As long as these parts

work properly, the eye maintains its normal color, size and

shape, and the animal can see.



If the eye becomes severely injured or diseased, some or all of

its parts may be replaced by scar tissue and are unable to

function.  As a result, the whole eye may degenerate and even

shrink.



Degenerative changes may take several days to weeks.  As the

disease progresses, the natural color begins to fade, the eye

becomes smaller and possibly irregular in shape, and permanent

blindness may result.  This final state is referred to as

phthisis bulbi.  If no infection is present, it usually is not

painful or dangerous to the overall health of your pet.



                 Important Points in Treatment



1.  Phthisis bulbi cannot be cured.  Treatment, if any, will be

    directed at preventing discomfort.



2.  Because the eyeball is shrunken, a wider space is created

    between the eyelids and the eyeball itself, and mucus may

    accumulate within that space.  You should wipe the mucus out

    gently with moistened cotton or a tissue.  If needed,

    medication will be prescribed.



       Notify the Doctor if Any of the Following Occur:



    * The appearance of the eye suddenly changes.

    * Your pet shows continued signs of discomfort.
