Maybe someone else knows how to minimize it's impact. But either way, I always tell my docs what that spot is before they review any images that contain it... just so they are aware.

I concur with Gary. I believe it is an Allen dot. It also shows up on my camera when I have a very myopic patient. It is a dot in the center of the objective that helps with not receiving reflections back through the lens. It only shows up on myopic patient because of the focus that you are having to use to get a clear view of the fundus. Like Gary, that's one of the ways that I can tell if the patient is a high myope, if I didn't take the images myself.]]> Wed, 24 May 2017 15:31:53 GMT https://www.opsweb.org/forums/posts.aspx?topic=1567525 https://www.opsweb.org/forums/posts.aspx?topic=1567525
The same optical artifact is seen in Blue Reflectance, but more so if there is a Cataract/PCH/PCO, but then magically filters away under FAF an AF. :/]]> Mon, 17 Aug 2020 16:43:16 GMT
