@@ansnfbsknanssshshbsnsndnd5438 Well, I asked our AI overlords and expected a single answer but found that they can diagnose it SIX different ways: 1. Retinal Hemorrhages: Leukemia can cause bleeding in the retina, which may be visible during a dilated eye exam. The ophthalmologist might notice small, pinpoint hemorrhages or larger areas of bleeding. 2. Roth Spots: These are retinal hemorrhages with white centers and can be indicative of leukemia. They are caused by microinfarctions and are a sign of systemic illness. 3. Pale Optic Disc: An optic disc that appears unusually pale can be a sign of anemia, which is a common symptom in leukemia patients due to the disruption of normal blood cell production. 4. Infiltration: Leukemic cells can infiltrate the tissues of the eye, leading to visible changes such as swelling or lesions in the retina, choroid, or optic nerve. 5. Uveitis: Inflammation of the uvea (middle layer of the eye) can sometimes occur in leukemia patients and can be detected during an eye examination. 6. Visual Symptoms: Patients with leukemia may report visual disturbances, such as blurred vision or floaters, which can prompt further investigation by the eye doctor.

My mother works at a glasses shop. While she's not an optometrist herself, they do have an optometry service in the shop. One day a client went to get his eyes checked, and after sending the images to the laboratory, he browsed for glasses for a few minutes and left. Just after he was out the door, they got a call. Paraphrasing: "Is the client out yet? This is urgent, if you can still get to him, tell him he's having a heart attack and he needs to get himself to a hospital immediately, or call an ambulance." They did reach him, and he was surprised, but he did get to a hospital on time. A few days later he went by the shop to thank them, because thanks to the early warning he was at the hospital when the worst of it happened, instead of in the middle of nowhere driving, and he probably lived thanks to that call.

I was the System Engineer for the Zeiss Clarus 500 retina (fundus) camera. It is an interesting engineering challenge to get enough light INTO the eye through the pupil to illuminate the retina, and not have that light screw up the light reflected off the retina. It is the reflected light that generates the image. That reflected light has to come OUT of the eye through the same pupil. The second tricky bit is trying to see a full hemisphere inside the eye when your only way in is through the fairly small pupil.

My doctor also will show me my pics and explain what he's looking for and seeing, which is nice, especially since my family has a history of diabetes.

I'm going to have a diabetic eye test tomorrow. I get one every year. Between the last one and tomorrow, I had a typical eye test (because Mum had glaucoma, my sisters and I are given a free eye test every year), and the optician discovered the beginnings of cataracts. I've got about 4 years before I lose my sight, but because it's been discovered, I'll be on the operation list sooner rather than later. I have a lot of time for opticians. They know more about our general health than most people would ever imagine.

I always get a retinal scan, and one I got 2 years ago showed new hemorrhages that were not there before. They told me to check in with my primary care and I did. Found out my blood pressure crept WAY up as a side effect of a medication. I then stopped the meds and it normalized.

Fascinating how what's been conceived for spy tech in films is now contributing greatly to health sciences. The possibilities that emerge from broadening the visibility of the retina to detect diseases early sound promising.

The specialist found a hole in my retina that could have increased in size and possibly cost me the vision in my left eye. I had laser surgery on that eye and now see him every six months to monitor that area. Hopefully, fingers crossed that it doesn't get any worse

My optometrist has had one of these cameras for as long as I can remember. I’ve always felt better knowing they can track ocular changes over time and the at they can pick up on other problems beyond the eyes.

Early diagnosis has allowed her to change her diet and reduce her blood sugar levels.

Harry I wear glasses and i had no idea when last week i got my eyes tested .I hadn't been to the opticians for almost 5 year and i wondered why things looked very blurry through my left eye .Turns out I have a cataract.Got to see the doc for an operation. I'll make sure to ask more questions about my health when I see the optometrist again.I heard that magnesium taurate helps with cataracts . Do you know if this is true ?

@@simonscott5104 Magnesium Taurate definitely doesn’t cure cataracts. Only surgery can remove/ treat them.

I came for the science info. I stayed for the wonderfully delivered, horrible puns.

I got that done at a recent eye exam. My eye insurance didn't cover it, so it was around $100. Everything looked fine, so I don't plan to do another for 5 years. I was also able to see what the doctor was seeing, so that was really cool. She said the back of my eyes are lighter than normal, so bright lights and sun probably annoy me. She was spot on! Everyone thinks I'm dramatic for wearing my sunglasses everywhere. lol Didn't hurt, and I got to skip the air puffs into the eyeballs test!

Been having this done yearly for several years now. Been very helpful

I enjoy puns of all kinds, so I found this film entertaining as well as informative. Punsters of the world, throw off your shackles!

Retinal scan saved my vision a few years ago. Confirmed I had an infection that could have blinded me if I waited much longer to go to the ophthalmologist

Hello, they've been doing this in Europe for decades!!!

My optometrist has been offering retinal scanning and photos for over a decade. It is a very helpful tool that should be made available to everyone.

Great job Sci show! Still great after all this time!

This is excellent! This is why I see an ophthalmologist regularly, not just an optometrist - at least in Canada, it is the largely the doctors who have retinal scan access/expertise. I do have very early stages of eye diseases, and comparative photos are great. Having an eye doc experienced in interpreting images means she is picking up on subtle things that I certainly can't make out from background noise... It also provides incentive to follow good eye nutrition, etc. And you've given me excellent additional info on other things I can ask about when we look at my scans... both diabetes and strokes are a personal concern too!

I reflexively roll my eyes when you guys force puns.

Our Optometrist says she can see Multiple Sclerosis as well, often before a person knows they have it. If she sees the signs, she just recommends they see a neurologist on her reccomendation. On a completely different track, we adopted a cat who was "mostly" blind. So we took him to the vet and sure enough, the vet said the cat had severely reduced nerve and blood vessels in the retina, pointing to poor nutrition as a kitten. "Probably fed dog food" the vet said. Then he told us the other problems our cat would probably have. INCREDIBLE!

Very interesting to learn how retinas are connected to other areas of our health. I have lifelong retina disease and it is interesting to see how this technology has evolved so that retinal cameras are now part of my regular exams, previously only in hospitals.

Years ago my optometrist told me to go to my GP to get my blood pressure checked as there was a burst blood vessel in my eye (something like that anyways). Luckily it was only stress related high blood pressure and getting more exercise and taking more holidays seemed to do the trick. But it’s good that they’re there to pick that stuff up.

I have a rare form of intracranial hypertension, and they do retinal scans on me every year as another way of checking what is going on with my brain. It also doesn't involve 45min of a needle in my spine so I'm down. Now if only it was better covered under healthcare...but I have a brain disorder, and I can go on about U.S. medical coverage allllll day.

As every other american citizen can. Healthcare should NEVER be a for-profit enterprise. There's nothing wrong with paying doctors and nurses large salaries because of the rigors of their profession, but there's everything wrong with profiting off of the misery and illness of human beings.

There are different types of “retina scanners”. You’ve got the optical fundis cameras that just take a picture, but then you’ve got really fun optical CT scanners that more and more practices are using. That’s where you get to image the thickness and capillaries and so much incredible data. You can also pre-diagnose things like MS from a visual inspection of the retina.

Those CT scanners are called "OCT" Optical Coherence Tomography and utilize infrared light, which thankfully unlike a lot of imaging does not subject you to radiation at all. Mostly used for checking the thickness of the optic nerve, due to glaucoma and other eye pressure problems as well as looking through the retina to image different layers of the retina, usually for diabetes and macular degeneration.

I've been getting a couple OCT scans a year for the past decade and even these machines have improved a lot in that time. Before these two machines I used to have to get angiography pictures taken with an IV drip for contrast in order for them to accurately see all my blood vessels etc.

Years ago I had a retinal scan that revealed several non-ocular health issues including elevated spinal fluid pressure. Wild!

My Optometrist referred me to an Ophthalmologist who then diagnosed a Paraneoplastic Ophthalmology Syndrome. Even if you have good vision, go get your retinas scanned. This video will save lives :-)

About 3 years ago my optometrist caught the beginning stages of a retinal detachment thanks to doing a retinal scan. I was able to quickly see an ophthalmologist and have laser eye surgery to seal off the "bubble". After finding another one in my other eye and having the surgery again, I've been perfectly fine ever since! The same optometrist also figured out that I had an autoimmune disease, Sjogren's Syndrome, thanks to my severely dry eyes. Very thankful for all you optometrists out there!

As a diabetic, even though my insurance won't cover this, I get the pictures every year to check for retinopathy. So far so good.

Well, the James Bond puns are worthy of 007 homself!

Whoa no way! I published some papers on this a few years back! Retinal venular tortuosity (how twisty and tangled your retinal veins are) and retinal amyloid plaque burden (how many amyloid plaque tangles were counted per unit of area) were correlated with more severe degrees of cognitive impairment, which is super important because, as the video notes, people are far more likely to see an optometrist earlier and more frequently than they would see a cardiologist or neurologist, leading to earlier detection and intervention for Alzheimer's disease and related dementias and cardiovascular disease. So cool to see a topic I've published on make it into a SciShow episode!

Type 1 diabetic here since I was 9 years old - this is amazing news! Every 6 months I need to get another retina scan. Over the past 4 years, my eyes have gone downhill fast. Bleeds near the blind spot, hair vessels that are popping and trying to repair itself in very dysfunctional manners, scarring tissue and fluid leakages in the glass body, spots and blurs in my vision, weakening of the eye muscles, developing horrendous photophobia.. it sucks bum, to say it lightly. BUT - knowing that the instruments and devices are changing for the better, means that treatments are also getting better! That makes me SO excited! The earlier we can spot signs of disease, the faster we can treat it, the more treatments will develop, and the better the prognosis will be. I hope that everyone of the future generations have access to regular retina scans, to spare their health AND to ensure they keep their eyes as healthy as possible! 💜💜 Fun fact: my T1 diabetes also affected my pupil contractions, which is why I developed photophobia. My pupils are ALWAYS dilated like it's nobody's business. But a big upside of this - I don't need eye drops during scans lol! Finally a benefit from all those shitty health complications 😂

Thank you 🙏

Loved the I.F. James Bond's jokes "pun intended"

My husband has Type 2 diabetes and has had two eye surgeries because of bleeding retinas. This technology has literally saved his eyesight.

I have a personal experience with this tech. I was born colorblind, a rare form which leaves me the ability to only see primary colors. At age thirteen my eye doctor looking through an otoscope diagnosed me with macular degeneration. Based on the light my retinas reflect. However a few years ago I had my current eye doctor, who took over the other's practice after his passing, gave me one of these fancy scans. Turns out my eyes lack so many rods and cones that it's truly a wonder I don't see black and white. It was quite a learning experience because we found out the Mac degen was a misdiagnosis. Not the original eye doctor's fault. He called it like he saw it. The scan helped me to acquire SSA disability, which is fine because I have other conditions like bilateral pendular nystagmus making me undraftable and my vision is only correctible to 20/200. Can't drive. I'm ok with it though. I would have liked to serve. And I have mad trouble identifying secondary colors, browns, pinks, and such but I've read more books on color and know more about classification systems than most. Before computers for instance we had colors narrowed down to 255. VGA monitors in the 80's bumped that up to 2.5 million and now 4K/Hd screen tech puts the number beyond billions. So many they couldn't possibly be named. They require numerical designations based on how much the red, green, and blue light is used. It's all really interesting.

As far as using the eye for security purposes go, using the iris is a better, more feasible option. Irises are also a good way to identify individuals, particularly color images. I was an ophthalmic assistant and was amazed (and delighted) to see the beauty of patients' irises. As far as the retinal images go, yes, ABSOLUTELY, spend the $39 fee for at least a baseline photo. If your retina looks good and you are in relatively good health, you can skip a year, but get at least one....so that if your eye doctor ever DOES find something, they can show you the changes that have taken place. People often don't "get it" if the first image of their retina that they see has only some small "blip" on it. If the doctor can show, however, that the "blip" (whatever it might be} wasn't there LAST time they had photos taken....patients generally will "sit up and take notice"...

What really sucks is that eye car isn't part of normal health insurance. But further to that point, most eye insurance doesn't cover this particular procedure so you have to pay out of pocket for it (at least partially).

What is stop them, it proving it can it can catch diseases faster then doctor looking at you.

My eye doctor uses these machines. The annoying thing I have with them, is that my insurance doesn't cover the screenings with the machines. I think it's important, so I have a flex spending account that I use to cover the cost, but American insurance companies really suck and make us all at more risk than we need to be.

I have retinal scans done every 4 onths or so (free at point of need) at St.Thomas's Hospital, London, UK as I have diabetes. I have had two cataracts removed and my vision restored (6th June 2023 & 1st September 2023) And had implants inserted (once in my left eye, twice in my right eye), to reduce oedema / swelling on ny retinas caused by the diabetes. My next apointment's due this coming August 2024. So far, so good, considering...(And _no_ bills to pay - it's all done on the NHS).

My Optometrist ask me if I wanted a scan. I said "Dr, No". I'm not giving you a ... View to a Kill". Bawwwhahahahaha.. Don't get up. I'll see myself out.

My Dad is being treated by his eye doctor for small pockets of fluid that accumulate within his retina which are related to diabetes. A scanning machine he sits down at is able to produce cross-sectional views of his retina like those shown at 5:11 in this video. I find it fascinating that we have a machine you can simply look into that is able to produce cross sectional imagery like this. The geek in me would very much like to know the fundamentals of how they work.

I know Savannah is enjoying the Bond puns, but they're actually hurting me. Great episode, as always folks 👍🏼😁

I have an extremely rare autoimmune disease that was discovered by an optometrist using this machine to see that my optic nerve was inflamed badly. If it wasn't for her quick reactions it's likely that I'd be blind in one eye and possibly paralyzed. So, yeah ... good machine - I approve.

My eye doctor has always been super proactive on making sure my overall health is good, even saying that he’s move up my appointments if/when I get my EDS diagnosis because of the way the syndrome can presents in the eyes. But then I also have super weird blood vessels in my eyes so maybe I’m secretly being put into a textbook.

That’s a great video about the way retinal scans can help people in ways other than with their eyesight but you didn’t mention why optometrists and ophthalmologists do it. Speaking as someone who, as a child, was talked down to and told it was too hard to explain why I have bad eyesight. And, as someone who, in my 30s, had an optomotrist photograph my retina then walk through an explanation while also showing me other people’s scans for reference, I think this kind of thing is important.
