So what happens when a person gets a retinal degenerative disease like macular degeneration?

So, a solution to the problem, then, would be to build a device that could mimic the actions of that front end circuitry and send signals to the retina's output cells, and they can go back to doing their normal job of sending signals to the brain.

There's also another one over here called the superior vena cava, and this is bringing back blood from the arms and head.

There is actually a little spot right there that they drain in to.

And it generally travels through two major kind of vessels.

So let me start in on that problem.

This is now going to dump into what we call a venule.

Yeah, it's called Retinitis Pigmentosa.

And it came up in the right atrium from a giant vessel up top called the superior vena cava. And this is a vein of course because it's bringing blood towards the heart.

Colors are flavonoids and polyphenols.

I'll write that right here.

Into the IV, yes.

It works.

So you have these arteries right over here, the red tubes. Those are arteries. and then the blue ones are veins.

I found out the the following.

So Superior Vena Cava and Inferior Vena Cava.

Stem cell derived retinal transplants, now in a research phase, may one day restore vision, or part vision, to millions of patients with retinal diseases worldwide.

It's a very difficult procedure, but it is possible to photograph this image.

But fingerprints and retinas are unique.

This is another example of patient specific stem cells that were engineered from someone with retinitis pigmentosa.

We're going to take these blue light photosensors and install them on a layer of cells in the middle of the retina in the back of the eye and convert them into a camera just like installing solar cells all over those neurons to make them light sensitive.

And at the bottom here, you can't see it because it's on the other side of the heart, but there's another vein called the inferior vena cava.

In metaphase I let me just copy and paste what I've already done the nuclear envelope is now gone.

They receive comprehensive eye exams.

51 Days

And let me actually show you where the blood vessels come from. These are called coronary vessels I just write the word coronary here.

So that's called the visceral pericardium.

little bit and show you how a normal retina works first so you can see the problem that we were trying to solve.

Inferior vena cava, and this is the large vein that brings back all the blood from the bottom half of the body.

They'll be so small, they'll be embedded in our clothing, in our environment.

And, how come you can't detect colors when it's dark?

And then you've got the capillaries, you've got some blood kind of from both places the pulmonary circulation and the blood from the systemic circulation again mixing.

Start a largebore IV. Keep it open.

It'll just bake your retinas.

I could just write artery and vein and essentially they would be behaving this way.

So the first branches go and serve the heart. So it's kind of the first to get systemic circulation blood.

Here's one that's in prototyping by Medtronic that's smaller than a penny.

So it consists of two parts, what we call an encoder and a transducer.

So we are really duplicating the kind of signals that you have on the optic nerve.

So these two veins, the superior vena cava and the inferior vena cava, are dragging the blood back to the heart, and, generally speaking, these are all considered, of course, veins.

There are actually separate names for the two layers.

A venule, and this venule is gonna basically then feed into many, many other venules.

I had retinal detachment five years ago.

And then it's gonna come out on the other side, in the pulmonary veins.

I just wanted to say something about the standard method.
