And i think the most important part about thinking of how the retinal physiology goes forward when you're doing dark at itami tree what you're actually measuring is of rpi dysfunction. Because what happens in dark at tommy trie is that visual cycle becomes impaired vitamin a. the retinal transport across the rpi is impaired. So you start to have this lack of sensitivity return and You know certainly i have no stock. I own none of these companies. I'm just familiar with the The one clinical device adapt the x. And really we have had a lot of great success in a lot of literature points to the fact that if you started identify dark atacama trie issues early. That is a precursor. In fact it's been defined almost as a feature of early. Amd and i think we start to really pour into the literature about pharmaceutical nutraceutical at some of these early lifestyle changes. I think we can start to change course on these numbers. You're totally leading me to the next to the next topic. Forehead there your mom jessica. You mentioned that in your practice. You're you're re quickly targeting and seeing more advanced cases though you did mention you do see some early too early earlier. To intermediate cases as well but given the amount of volume of patients that are being referred to you in all likelihood due to progression. Do you employ any type of instrumentation. That has a goal of early diagnosis. So we actually don't have dark at tommy train in our practice and a lot of that is because of the fact that we're not seeing these earlier stage patients quite as frequently And typically we're not gonna get someone until at least they already have signs of amdi like clinical signs the you're on the fundus evaluation on the oc t evaluation or the fund auto fluorescence or intermediate or advanced. But like. chris said. I mean there's a huge need to identify these patients early on and to modify risk factors early on because these patients who we see who are eight years old and then get referred to us because they have cordani of aspiration or they get referred to us because they have geographic atrophy. They're not seeing well. And even though there's not a lot we can do for geographic atrophy. They kind of. I think those wanna send them out for that second opinion that you know this is also that we can do but when that patient sitting in your chair. And they're eight years old. There's been eighty years of life you know..
