Peace of mind for practitioner and patient

Product: Canon OCT-HS 100

Supplier: OptiMed

Ocular coherence tomography has revolutionised the way we look at the retina. The high definition images of the retinal architecture we are able to capture within a matter of seconds now form part of our daily routine practice. This diagnostic tool allows us to make a timely assessment of our patient’s ocular health and where necessary, refer for a second opinion or surgical intervention.

Patients are now very accepting of new technologies such as OCT. More than ever, they rely on our professional expertise to provide solutions for their demanding visual requirements.

I have worked at the OPSM Eye Hub since it opened in July 2010. Over that time, we have developed a better understanding of how powerful the OCT can be. More importantly, the routine use of OCT provides both optometrists and patients with peace of mind regarding lasting ocular health.

I recently had the opportunity to test the new Canon OCT-HS 100. It has unique features that make it simple to use, easy to incorporate into routine consultations, and very informative and easy to understand for our patients.

Key features

Its automated eye alignment, eye tracking and focusing mechanisms offer benefits for both practitioner and patient. Patient fixation is now much simpler with the automated eye tracking. By automatically aligning with the centre of the patient’s pupil this feature makes sure we have the macula or optic nerve in the most appropriate position for an accurate scan. The automated focusing mechanism ensures that even beginners can obtain crisp images with maximum diagnostic value.

Another key feature when performing high definition (HD) raster scans is that both vertical and horizontal sections are captured simultaneously. This allows us to efficiently obtain a thorough insight into any retinal pathology and assess a larger area of the macula. A quick roll of the wheel on your mouse allows you to transition between the five vertical or horizontal HD raster scans.

Quick, thorough assessments

The software package is simple and intuitive to use. On a recent fundraising day, I had the pleasure of working with Louis Eppel from OptiMed to help raise awareness and funds for the Macula Degeneration Foundation. I understood that I would be capturing and assessing digital retinal images with a Canon retina camera, but I was caught off guard by Louis who told me on the day that he had brought along the new Canon OCT to enable even more thorough assessment of patients’ eyes.

Having overcome my initial apprehension about using a new piece of equipment for the first time, I sat with Louis for five minutes and he walked me through the process of capturing and assessing retinal images. I felt like I was in the deep end of the pool but I was not drowning. It was a very rewarding and enlightening experience. After performing both macular and disc scans on over 50 people within a couple of hours, I can testify that with the Canon OCT, it truly is only a matter of a few clicks form start to finish for each examination.

Patient education

The clarity and organisation of the visual displays are well designed and organised, and clear. The displays allow efficient diagnosis, easy patient explanation of the retinal scans and quick understanding from a patient’s perspective. It always pleases me to see that my patients appreciate and understand what I have shown them when we look at the images of their macula and optic nerve. It is easy to see what a huge impression the OCT images make when patients make insightful remarks like ‘I now understand the difference between wet and dry macular degeneration’ or ‘It’s great to know that my glaucoma is stable because the retinal nerve fibre layer is not changing’.

I highly recommend the Canon OCT-HS 100 to all optometrists. It is compact and fits neatly into the smallest consulting room. Its benefits and features meet both practitioner and patient needs. OptiMed’s services are timely and efficient and its long-term support is second to none.

The technical information regarding the Canon OCT speaks for itself with 70,000 A-scans per second, and the production of a 10 x 10 mm (44 degree) 3D tomograph of the retina in about two seconds. It also uses an SLO for its superb and detailed fundus preview and for its automated eye tracking and scan registration. The ability to import a Canon retinal camera image and overlay it with an OCT scan is a neat feature.

I look forward to the imminent release of a Caucasian normative database for the software package to make this OCT even more powerful.
