PHOTOGRAPHY
TIPS: Eye tumours of the older dog. "P" Mode and Zoom lens
used in 2010. Singapore. Toa Payoh
Vets, 17 Jan 2010. Image of a right lower "eyelid" tumour in
the older dog. I practised photography using the Zoom Lens of Canon
EOS 40D, 70-300mm.
I had this EOS 40D
camera and the Zoom lens only as I did not spend money on various
other lenses to document my case studies in 2010. EOS 40D was a much cheaper
camera than what the Canon R5 I use now in 2024! Its lens was not as
good, but it was more affordable. Canon 40D,
P Mode. 214mm, 1/1600 sec, f/5.6, ISO 400.
In 2010, I was
advised by a photographer to just use the "P" Mode to take
photos as the "Program" Mode would do all the settings of
shutter speed, aperture and ISO for me! I did not want to spend
more time to learn more about the use of AV, TV and Manual Modes as I
was busy and had only limited time in practice!

THE
FOLLOWING ARTICLE IS SOURCED BY THE CLIENT FROM THE INTERNET:
EYELID
TUMORS. Older dogs commonly develop eyelid tumours (cancer). As
in humans, cancer can be either benign or malignant. Fortunately,
eyelid tumours in dogs are usually benign and do not spread to
distant tissues. However,
eyelid tumours do slowly or quickly grow, and can destroy the
structure of the eyelid, in addition to rubbing on the eye. It is
usually best to remove them when they are still small.
Eyelid
tumours are treated by surgical removal. While there are many
different surgical procedures possible, most eyelid tumours in old
dogs can be removed at (Name of clinic) without requiring general
anaesthesia. The
patient is given a sedative, and then a local eyelid anaesthetic is
given to numb the eyelid. The tumour is removed and the site
frozen with liquid nitrogen (cryosurgery) to kill any remaining
tumour cells.Tumour
cells are usually very sensitive to freezing, and normal eyelid
tissue is more resistant. After surgery, the eyelid margin turns
pink (de-pigmentation), but usually re-pigments within 4 months.
DR
SING KONG YUEN'S COMMENTS: This internet article, from
the dog's owner, refers to eyelid tumours which grow on the eyelid
itself. They are usually less than 5mm in diameter and this clinic
suggests local anaesthesia and cryosurgery. This avoids the general
anaesthesia risk of death in the older dog. All vets must advise on
this general anaesthesia risk and all owners are worried. However,
in this case study,it is NOT practical to use freezing of the large
tumour which is NOT an eyelid tumour but a large tumour below the
eyelid. General anaesthesia and surgical excision were successful in
this case and the dog no longer rubs his "eyelid" tumour, worrying the owner daily!
