My best friend has Retinitis Pigmentosa. He is only 14 but will be totally blind in 2 years. He loves this video and from what he could see with 25% of his vision, he loved it! He said thank you to all the people who helped make this video and are continuing research! He hopes to see them some day.

Now can someone explain to me how the hell did somebody found out that the zebra fish can regenerate it's eye sight?

That zebra fish is too cute

These guys make it seem so easy.

I had a macula off retinal detachment in my right eye. I noticed a shadow slowly encroaching towards my center of vision. I sought medical attention but thanks to good old American Heath care (or lack there of) it was too late to save the fine detail vision of my macula. After a corrective pars plana vitrectomy my vision was mostly restored, just one more surgery to go.

Ive had zebrafish in aquariums before, one of my first lost one of its eyes before i got him and still managed to be the cutest thing and then one of my last managed to survive MONTHS in a tank that wasn’t being taken care of. No filter not heater no water changes, zebrafish are hardy and very unique fish that need more recognition AND have helped us a lot in research also they’re as cute as those animations!

@3:33 is that a flux capacitor?

All these eye vids have restored faith in my eyes/vision.. thanks from the bottom of my heart

Very nice and informative video. And should say - very great animation. Unlike in some latest video - very clean and clear, really helping to understand material. Good work!

This made my eyes hurt

Is it just me or does this guys voice sounds a bit robotic? Also great video. Hopefully we will be able to cure blindness.

I really liked the animations in this video :)

It would be nice to revive my eyes, when I was young I didn't have glasses :(

3:40 i love how the cone receptor is wearing 3d glasses😂😂

Beautiful. This is why I love TedEd. Very informative.

Could we cure color blindness too? Can there be a way to trigger the growth of specific cones?

who knew zebra fish were so interesting, i remember having them in an aquarium

Will this idea works in the regeneration of near by optic nerves...so that it aids in curing optic nerve hypoplasia?

Really u guys..are making a really good info in a awesome way...👏👏

God damn zebra fish. stealin' OUR superpowers

I request you to make a lesson about mystery or genetics of eye color.

I think the Muller cells are activated by transcription factors-like signals from retina, these signals go on to induce specialization in areas of muller cell (gradient based). These specialized cells then replace the cells or truncated cells, which is what we see as regeneration. I think.

Wait so... are there Flux Capacitors in my eyes?

My son is suffering from total retinal detachment and he is just only one year and doctor said that there is no treatment of this disease pls guide me about this is. There is any treatment of this

Love your constant BTTF references!

saffron helps fight (almost cures) macular degeneration if taken early and/or beforehand. How does that work?

Zebrafish is awesome, great video. The adult newt can also regenerate the retina, lens, limbs, heart, jaw, spinal cord, and brain. I hope in the future TED-Ed can present a video on newts regenerative abilities, it would definitely supplement this area of regenerative biology.

I got a bit confused, does the human eye have those "Muller glia" sells? is it the sells themselves or it's their regenerating function that is so special about the zebra fish?

Great Scott!

sir I am to surfing from retinanitis pigmenttosa . now I can't see in both side in daylight , now what to do

"Which is why babies have such big eyes and why they're so cute" That last part tho 😂

I want to kiss a zebra fish...

Could this potentially fix eyes on a person who experiences Colour Vision Deficiency?

Good, but more important would be to focus in the repair of the optic nerve, when this is damaged, causing blindness.

Can other parts of the eye be transplanted after death like our retinas?Or just the cornea? I've met a person that was blind before because of cornea damage,and before he told me that,I did a dark joke about eyes,blindness or corneas(I don't remember the joke anymore,it was one of those that depend of the context of the conversation I was having in that time) to him that creeply enough,he confirmed that was what exactly happened to him.He had a corneal transplant and started to see once again,since then,I wondered if it's possible to transplant other eye parts,not only with cornea.

Great vid guys

Do you think it's possible for iris to regenerate, from someone suffering from iris atrophy?

Listen to this podcast, there are some interesting facts about vision. There is a specific part (40:00) that relates to how images are constructed in our brain, even for bind people. www.thisamericanlife.org/radio-archives/episode/544/batman

There were so many back to the future references

Zebra fish is like Deadpool.

Luv the animation

Please Answer. My friend had cancer called Ratinablastoma in the year 2006. Now he can see only with one eye ,the other eye was removed at that time.His optical nerve was damaged.My question is can he be able to see with both his eyes in the future ?? Please answer !

Thanks ted

What about Macular Degeneration? That's what took my grandfather's sight. :-( We all watched his slowly go blind over a course if 17 years. It started when he was 64 and ruined his retirement. He also had glaucoma and other eye problems that i don't remember the names to.

3:40 Dude was that the flux capacitor?

my grandmother has been disorganized with 'diabetic retina as many know diabetes often affects the rest of the body, including the liver and eye. every once in a while she gets surgery to ensure she doesn't eventually go blind. yet her eyesight is still worsening she can't even read without huge glasses

My name is Cathy and that is happening to me I already can't see out of one now my left eye is cloudy what can I do before I lose my eye sight please help

the zebrafish was so cute

wow

Really great and informative video!Science is always so interesting.Life is so much better with science,especially medicine :)

Being blind is probably the worst sense you can lose.

but does this mean, installing a robo eye capable of x-ray vision is no longer an option when this research is completed? because i think robo eye are cooler.

I never want to go blind it is my wish to never go blind

Do humans' eyes have the Muller Glia structure?

And 3:34

Was that the 'Back to the Future' time traveling device. that 'Y' shape thing

Loving zebra-fish

What will always be true is that if you put just a little too much detail into drawing eyes, they can become really creepy!

EYE SEE what you mean it REFLECTS my past

I can see why this is an interesting topic

Most people see sharp but they are blind because of their brain. This video is fantastic!!

My dad has retinitis pigmentosa so this is pretty cool :)

I dont know who is looking for the smirk but here it is 0:53

THIS IS MAGIC!!!!!

The clue for this is water! Blind people should open their eyes in the water

1:35

Cool video😃

The Zebrafish = wolverine lol

Go to 0:35

We can't even make our crystalline lens change shape, it would take really long to regenerate retina

So we don't need to harvest from different places Stem Cells? We can just grow them from these fish?

me in 2015: hay future me dose this happen in 2019 me in 2019: no but we have egg dog me in 2015: oh *THAT'S WAY BETTER*

We learn so much from nature!

I worry we won't be able to regenerate eyesight until well after Star Trek TNG with Geordi.

Although we share a common ancestor with the zebra fish it's likely that they did not have that trait even though most of the eye probably was very similar. The trait would have been much more widespread with a lot more species having it. I wonder why zebrafish has this. Their ancestors must have had a harsh time surviving such that this trait was vital for their survival at one time.

The Retina, Woohoo!

But it could make a big problom

Zebra fish is marine Deadpool.

I strongly believe that someone will comeup with a great discovery that some natural plants or exercise or else could longer the life or rods/cones cells and thus blindness can be cured 😀 I have already heard of brain lesions are not permanent and they get resolved under proper condition Similarily about neurogenesis Some day My belief would come true

now whose brilliant idea was it to put the cables and wiring in front of the screen?

There's also the ethical and moral conundrum, though. Not everyone without sight thinks of him or herself as "broken" and in need of a "fix," so who are we to not even consider that?

Plz help

That zebrafish is cute~

I need help for a great person

that fish uses special medative techniques to regrow complex celsl.. only intuition can comprehend the dephtness ...

My eyes seem to have been degenerating, I've been having problem seeing during a bright, sunny day or reading signages from a distance.

Babel fish for ears; zebra fish for eyes.

The flux capasator!!!

can a zebra fish be immortal? they can even regenerate the heart so they won't die?

Once again, I am reminded on how lucky I am to have good vision. I mean, half of my friends wear glasses

So parts of your eye have eyes? Must be a never ending cicle.

good morning

Wait so the mice can also regenerate the eye like the zebra fish?

Hey, step cell.... W..what ar.. are you doing step c..cell?!!!

Wait Only a zebra fish Or all fish does?

If your parts of the eye has an eye too They maybe blind too And maybe thier part of the eyes has another eye Eye Eye So many eyes

This has been done successfully now, right? Or am I misremembering what I read?

Hmmm I lerned something today

Replenish

I don't understand😦...can anyone say could a blind eye can regenerate?...can able to see?
