Th- these, these are rare cases, but how can we, uh, move forward when we see these patients? What, what is the phenotype again of these patients, and how you will bring the, the, the patient to the diagnosis?

So usually, you know, this is, uh, something quite super acute.

A patient that is complaining of decreased vision, night blindness, sometime, uh, photophobia.

One key feature, especially for CAR and MAR, are photopsias.

They really describe flourish, uh, symptoms with flashes, uh, colors and things like that.

And then when you look at the fundus, you may see cells, so that's one differential diagnosis with uveitis, but you don't see much.

So this is really the case of a patient that has, uh, really major visual complaints, but you don't see much during looking at the, you know, standard examination.

And I wanted just to ask you briefly, uh, you know that we have this differential diagnosis and say, "Is this uveitis? Is it, uh, autoimmune ur- uveitis or is this a, uh, an IRD?" So what, what would you suggest in, uh, in these cases? What is now the, the best way to diagnose and to go forward for one or the other type of condition?
