Meet Dr Mark Billson

With the VetPrac Ophthalmology Workshop fast approaching, let’s focus on Dr Mark Billson, whose career in veterinary ophthalmology began with researching bovine eye disease. Mark, together with Dr Martyn King and Dr Edith Hampson, will help you see many aspects of ophthalmology more clearly at the VetPrac Ophthalmology Workshop on February 8-9, 2018.

Dr Mark Billson has been a Specialist in Veterinary Ophthalmology for 18 years and has practised at the Small Animal Specialist Hospital, North Ryde, NSW since 2007.

Tell us about your path from researching bovine eye disease to specialisation in veterinary ophthalmology?

My involvement in bovine eye research led to a fascination with all things ocular and being exposed to the basic sciences of anatomy, physiology, microbiology and immunology fostered a desire to better understand the clinical diseases of the eye and management of these diseases.

What is your favourite ophthalmic condition to treat or manage or your favourite procedure to perform?

I do not enjoy treating glaucoma, but I enjoy trying to get solutions for problems. While it is a challenge and we do not have all the answers, I do enjoy glaucoma surgery and placement of implants to address high intraocular pressure.

Are you working on any projects at the moment?

I am continuing to try and develop the treatment of glaucoma and refining the use of drainage implants.

What have you learned from experience that you didn’t learn from a textbook?

The biggest thing I learnt was that not every disease presentation looks the same. So just because it appears a certain way in the textbook doesn’t mean that is what it will look like in the clinic. This includes differences in environment.

What in particular do you believe general practitioners would benefit from learning about ophthalmology?

How to do a good exam. Everything in the eye is visible.

What practical tips can you share with general practitioners regarding ophthalmic exams?

Do the same approach on every case and always assess both eyes. Make sure you are familiar with your equipment and its limitations.

What advice would you give new graduates?

Don’t be afraid of eyes and don’t be afraid to ask questions.

What do you like to do for fun and to unwind outside of work?

I like to spend time with my family (beach holidays and tennis) and to play golf.

Thanks for your time, Mark. We look forward to sharing your vision for ophthalmology at the VetPrac ophthalmology workshop. If you’re interested in registering today please click here.

VetTips: Ophthalmology

Tip 1:

Pupillary responses to light, the menace reflex, the ‘dazzle’ response and even the ability to respond to a moving object in the visual field do not measure vision. Instead, they evaluate the integrity of certain neuroanatomical pathways. All these can be present yet the patient may still be unable to avoid obstacles or navigate.

Tip 2:

It is vital to the success of surgery to identify the cause of the entropion. Failure to do so will result in poor success rates and even worsening of the condition. Entropion can be either congenital, juvenile or acquired.

Before embarking on surgery ask:

  • Do I understand the cause of this entropion?
  • Have I planned the surgical procedure carefully?
  • Do I have the expertise and instrumentation to perform the procedure?
  • If the answer to any of these questions is no – consider discussing with your local specialist or join our Ophthalmology workshop to learn more.

Tip 3:

It is hoped that removal of an eye is not frequently necessary, but sometimes it is inevitable and we must decide which of the following procedures is best suited for the condition at hand. Most commonly the reason for enucleation is the “blind, painful eye”. Make an effort to recognise when there is pain and take time to explain to owners the usually extensive and irreversible loss of function in the eye and the difficulties in controlling the signs and symptoms, especially pain. Best practice indicates that the surgery is being carried out as an act of kindness for the patient.

Join VetPrac on the 8-9th of February 2018 for the popular Ophthalmology Workshop where you’ll develop skills that will build your surgical confidence. With over 7 hours of practical wet labs this hand-on’s stimulating environment will allow you to walk away with skills that can be immediately applied to general practice. Classes are intimate with unprecedented contact with specialist ophthalmic surgeons Dr. Mark Billson, Dr Martyn King, and Dr. Edith Hampson. Did we also mention the workshops are super fun?

VetTips: Ossability Cruciate Repair

Tip 1:

Patients will commonly present with medial meniscal disease secondary to cranial cruciate ligament (CCL). Meniscal disease is uncommon in patients with partial CCL ruptures or no cruciate disease.

Tip 2:

TTA was first described by Maquet in 1976 to reduce patellofemoral contact pressure in human knees with patellofemoral pain. TTA has never been used in humans as a treatment for cranial cruciate ligament (CCL) insufficiency. The concept of TTA being used for canine cruciate disease was proposed by Montavon and Tepic in 2002, and is based on a mechanical model of the human knee by Nisell in 1986. Nisell assessed cranial tibial thrust throughout human knee flexion and described a “crossover point” at which the cranial tibial thrust was neutralised. This crossover point has been shown in the dog to occur when the patellar tendon angle is approximately 90 degrees to the tibial plateau angle.

Tip 3:

When planning a thicker crest cut, use Gerdy’s tubercle as the caudal limit. Gerdy’s tubercle can be seen on a mediolateral stifle radiograph as a bone prominence immediately cranial to the tibial plateau and long digital extensor tendon sulcus.

Thanks VetScript for allowing us to share with the VetPrac community this article from VetScript December 2017.

If you’d like to learn how to use this state of the art technique in your own practice, join us at the join us at the Ossability Stifle System workshop 9 – 10th February 2018.

The techniques for cruciate repair keep evolving and each one has its place.The one thing everyone wants is a reliable method that can be used in most patients to increase the functionality of the limb and reduce their pain. The Ossability Stifle System has engaged engineering principals and high levels of personal supportive guidance to ensure your patients have successful outcomes. An evolution on the original TTA with improvements that address complications seen in other methods, this is a technique VetPrac is proud to bring the Australian veterinary community.

The General Practice Surgeon With Extraordinary Abilities… Meet Dr Abbie Tipler

Meet Dr Abbie Tipler – she’s an educator joining VetPrac in 2018 and will make her “debut” assisting Dr Brent Higgins at the OssAbility Stifle system workshop at UQ Gatton on February 9-10, 2018. Abbie is a fellow Kiwi, who moved to Australia to find warmth, as she only likes cold weather if there’s snow nearby. Abbie has 2 young children which keep her very busy, as well as 2 Ragdolls. One of the Ragdolls is cross eyed and not very intelligent, but is nevertheless much loved by Abbie and her family. Abbie has a love and a passion for surgery, and was born an animal lover, so it’s no surprise she became a veterinarian. Soon after graduation she developed her surgical skills, initially in London, in a combined GP and orthopaedic referral centre. Luckily the series “Suits” was not aired when Abbie was at secondary school, as she may have become a lawyer instead of a veterinary surgeon. Abbie watches Suits on constant repeat (when not running after her 2 young children, running, skiing or doing ballet), and thinks she was the character Donna in another life. She secretly would love to be called up for Jury Duty one day!

Abbie performs mainly orthopaedic procedures now, but loves ophthalmic surgery, as she gets to wear Loupes which, in Abbie’s words, make her feel more intelligent. Her advice for general practitioners who wish to pursue further education in surgery is to invest in CPD like you did your university education. In Abbie’s opinion your practice CPD allowance is usually not enough. She also suggests to not let anyone tell you that you can’t do a particular surgery, but pick the right cases with help from more experienced mentors and build gradually. Abbie highly values practicing on cadavers to help with improving skills with tissue handling, identifying surgical landmarks and anatomy. Sounds like Abbie will fit in perfectly with the VetPrac philosophy which is “Practical skills for practical vets”.

Abbie rates the support from OssAbility highly, and appreciates the safety of the whole system. She likes its step-by-step approach, and is keen to assist Brent to help others benefit from the OssAbility system. Like Brent, Abbie realises the importance of post-operative rehabilitation exercise in order to optimise outcomes, and involves her nursing staff in the delivery of advice to owners at discharge. She values a good team spirit in her workplace, and encourages new graduates to develop enhanced client communication skills, and to involve the owner in the decision making process.

VetPrac is excited about Abbie joining our team. For more information about the OssAbility stifle system workshop, click here. Or check out the workshop brochure here.
