The clinical appearance of hyphema is variable and is influenced by the vol
ume of blood and the amount of time erythrocytes are present in the anterio
r chamber. When hyphema is evident, a complete history should be obtained a
nd a thorough physical examination performed to direct the initial selectio
n of diagnostic tests. Secondary complications of hyphema include glaucoma,
synechiae, cataract formation, blood-staining of the cornea, and blindness
. Frequent measurement of intraocular pressure is recommended. The two prim
ary management issues in animals with hyphema are prevention of secondary h
emorrhage (by treating the underlying disease) and control of secondary gla
ucoma.
