A major asset in a rural setting

Canon OCT HS 100




Being in a rural location 500 kilometres from Perth, service and support were very important considerations in the purchase of an OCT. Albany is very well supported by Mark Stapleton from OptiMed, who spent a day setting up and instructing the staff on the operation of the device.

We got off to a good start with the HS 100. During the first training day, we discovered a macular oedema secondary to a branch retinal vein occlusion and exudative diabetic retinopathy that both required immediate treatment. We had an ophthalmologist in the rooms that day who was able to arrange the necessary attention for both patients.

With one flat screen monitor, the operator can sit in one position and switch between digital camera, field analyser and the OCT. Space is an issue in my small instrument room, so I am very pleased that the systems all perform together so well.

The HS100 is fully automatic and extremely fast. It’s very quiet in its operation and acquires 70,000 A-scans per second at a true three-micron axial resolution, with 10-layer recognition. It’s the highest resolution OCT currently on the market.


Glaucoma diagnosis is a careful analysis of a range of results and is never done by one measurement alone. OCT will never be a stand-alone diagnostic tool, but our optic nerve analysis is definitely more comprehensive with the addition of OCT scans. The HS100 full glaucoma scan (10x10 3-D) makes analysis of the nerve fibre layer much more in-depth and boosts our confidence in glaucoma diagnosis.

The statistical analysis is simple to follow and easy to read. The coloured sectorial graphs and displays are excellent for showing the patient the relevant results and present a simple visual display for explanations and discussion with the patient.


One of the huge benefits of adding an OCT to our diagnostic tools is its use in telemedicine and referrals. Our town has a resident ophthalmologist who is usually booked three or four months in advance, so with urgent referrals we can send the images electronically for opinions and earlier appointments. Clear and concise scans also assist telehealth Skype consultations with specialists when in rural and remote locations.

Generally, we have found the HS100 to be very easy to use, reliable and efficient. It has been easy to incorporate into the practice and a major asset to our patient management and diagnosis.
