5673. PHOTOGRAPHY TIPS: Eye tumours of the older dog. "P" Mode and Zoom lens used in 2010.

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!
