| Fundus photograph of a normal
2-year old spayed female DSH cat. This fundus photograph was
made using a 1.0 ND filter since this phenomenon is not easy to
demonstrate photographally without a neutral density filter. Note
the altered reflectivity (wide linear hyporeflectivity) located superior
and inferior to the visual streak. This altered tapetal reflectivity
was only transient in this very excited cat--it disappeared after 20
seconds or so and the enitre tapetal fundus had normal homogeneous
reflectivity. This is a common phenomenon that occurs primarily in
cats but also in dogs. We not only need to determine what the
(transient) cause of this phenomenon is, but also give it a
"clinically descriptive" name (tapetal constipation??).
$50 bucks to the person who comes up with the best clinically descriptive
name for this phenomenon. |
