Optos California ICG and Clarus 700

Wed, 17 Feb 2021 20:35:26 GMT

Hello all,

Looking for advice or experience with Optos or Zeiss Clarus

My practice is looking for a wide field camera, and to semi- retire our Zeiss FF450 plus IR. Two of our four retinal MD’s think the Optos California ICG may be the best choice. The most interested party in Optos stated to me he was not familiar with the Zeiss Clarus 700 and only slightly familiar with the Optos unit. So I did a basic breakdown of the two units side by side, presenting the information for review. My breakdown was regarded as helpful, and raised a few extra questions. The retinal MD’s now want some of the attributes of the Zeiss Clarus 700, like better color representation, higher resolution, but with the reported wide field degree of the Optos.

Recently we purchased a Zeiss OCT 6000 and will be adding Zeiss forum software in the next few months.

I am currently leaning towards the Zeiss Clarus 700, knowing it should integrate with Zeiss Forum software for review easily, also it seems like a closer true replacement for the Zeiss FF450 plus IR. I’m looking for photographers who have used one or both units and can weigh in on this topic, knowing we are a practice with multiple subspecialties including; Glaucoma, Neuro, Retina, External/Corneal, Pediatrics, oculoplastics and general.

Clarus hands down. I work in a peds practice and true colour is important. Sometimes our photo is the only view the mds get. Kids tolerate it well surprising. I thought hey wouldn't but they were all champs when we trialed it.

I have both cameras. Our practice has had an Optos since the 200TX, and now have both the California and the Silverstone. There is no questions that the field of view and the reach out into the periphery are greater on the Optos. I can image things on the Optos that are not able to be captured on the Clarus 700. Also, as of right now, the California can be configured to do both FA and ICGA, while, to the best of my knowledge, the Clarus is only capable of FA. Also, while the autofocus is very good on the Clarus, the fact that the Optos uses a concave (ellipsoid) mirror places everything in the image in focus. On the Clarus there is a single plane, (thick slice might be a better description) of focus, which is much deeper than in your FF450+. On the other hand, the resolution is better on the Clarus 700 than the Optos and true color of the Clarus is very nice. We use it frequently with our oncology patients to capture the true color of tumors to detect the presence of orange pigment in lesions. Also, one can take an anterior picture with the Clarus, which at least with my cvurrent level of skill, I am unable to do with the Optos. So if being able to go out further in the periphery is more important to your doctors than true color and higher resolution, then the Optos might be your better choice. Personally, I prefer the true color of the Clarus. FYI, no current financial interest, though I have been a paid consultant for Optos in the past. They’re both very good choices, IMHO. I hope this helps.
