Inside the eye (Day -285)

Vets and Eyes

Today I have been helping out on an Ophthalmology conference with an international expert on animal eyes, Professor Ron Ofri. Eye problems are something seen daily – yet can be extremely serious so I believe learning as much as I can about them is a good idea.

It was arranged to be accessible with stuff that can be taken into practice straight away, and through the day there was a focus on what as vets we can do. Some of it is simple such as testing if a cat is blind by following laser light (though have to be careful it is not a cat with a god complex!). There was only one surgery lecture and it was good revision – something they do teach really well at this university is surgery of the eye and eyelid!

One of the more interesting lectures for me was that of whether animals can see in color. It is a rather interesting question actually as a lot of people assume that animals can see, yet never question just how well they can see.

The question put forward was which of these have the best and worst sight: dog, horse or cat?

Surprisingly the answer was that the horse has the best sight, with the dog in the middle and then the cat with the worst sight.

Also interesting here is when you consider the field of vision. Imagine if you stand next to a horses head looking forward – you can see what is in front of you… yet the horse can see this, see you, and see what is behind you!

I completed my ophthalmology modules within uni last year– however one thing missed from this was instruction on how to use an ophthalmoscope. This was something that an exhibitor at the conference corrected with their explanations and demonstrations of several different types of ophthalmoscopes. This was made very interesting as he had in the past persuaded a person that modelled human eyes for ophthalmologists to practice on to make him some animal eyes with different pupil dilations.
