I review 47 images of the eyes of the fidgeting
Miniature Pinscher whose owner reject injections and
anaesthetics as a matter of personal preferences.
The green dye had stained the left eye 11-1 o'clock
cornea a zigzagging green. I saw it. The owner saw it.
But my camera techniques are lacking in that I can't
capture the ulcer clearly in the operating room after
application of the dye and doing hand-held. I had one
respectable image. What I needed was a reflector but
then Sunday was a busy day and I have not organised
myself.
This morning at 8.30 am, I went through the 47 images
again at home. Miniature Pinschers don't suffer from eye
ulcers unlike the Shih Tzus and the Pekineses. She did
have a small central eye ulcer scar of 3mm in diameter
in 2006 when the owner first saw me and that was the
only time I was consulted.
Clients in Singapore doctor hop whether it is human or
veterinary medicine but the vet must do his best in
the diagnosis and bedside manners as well as in his
receptionist services and other aspects. There are
many factors involved in retaining a client's loyalty.
In any case, I was surprised that I had not seen the 3
melanomas on the upper eyelid at the 11-1 o'clock
position. That is the cause of the ulcer which
appeared just below these "melanomas." The 9-year-old
spayed female dog felt irritated by these 3x3 mm lumps
and must have tried to scratch them off. So, there was
the zig zag upper corneal ulcer stained green. Vet 1
and I had not noted these melanomas as the dog kept
moving. For me, the right
eye was the main complaint and that was corneal
degeneration/dystrophy. But the left eye was not
normal as revealed by the green stain of ulcers.
The dog was moving. The owner did not want any
sedation nor did I ask since she was not in favour of
any injections or anaesthetics. She held the dog
tightly. I muzzled the dog. Focus was on the right
eye. The green ulcers in the left eye was picked up by
the fluorescein dye. But what was the cause? I did say
eye rubbing by the dog. The owner said: "I don't see
my dog rubbing her eyes. Is the green dye poisonous?"
Much of the time had been spent trying to flush away
the green dye while the dog avoided by moving her head
sideways. The owner tried to syringe the normal saline
and said: "I wetted myself".
The owner had wanted a
male vet to check her dog out. Was it Dr Jason Teo or
myself she could not say. It was me 5 years ago and so
it was OK with her as she did not want to go to the
"referred vet". I said: "Vet 2 could be
specialising in eyes and that was why Vet 1 refers you
to her."
She
asked if there are Singaporean veterinary eye
specialists in Singapore. "Presently, there is none,"
I said.
The "melanomas"
were small but could be seen clearly in the image.
This shows that visual aids are good for reviews and
help to diagnose. The right eye is likely to suffer
from a condition called corneal endothelial dystrophy
which is a opacity (lipid deposits) of the inner layer
of the cornea due to aging.
I phoned the owner and told her about the eyelid
melanomas which can be removed by surgery if she
wished. Also, the corneal endothelial dystrophy may
develop into an ulcer later. A blood test to check for
hypothyroidism and hypercholesterol and lipids and a
low fat diet of less than 8% had been suggested. She
said that her dog is on a vegetarian diet and thanked
me for the call. Later, I e-mailed to her two relevant
images.
