Mass eye injury event: The 1917 Halifax Disaster caused 592 people to be have eye injuries, including 249 enucleations by 12 Ophthalmologists, 16 patients had to have both eyes removed. Apparently most of the eye injuries were caused by broken glass. The disaster happened after a ship in the Halifax Harbour loaded with ammunition caught fire and began drifting on the water. After 20 minutes of burning, the ship detonated and killed 1782 people and injured 9000 more. A ton of people were watching the fire through windows in their homes/workplaces and when the ship exploded it shattered all thr glass of the nearby buildings (or just destroyed the building completely) Edit: apparently there were 5900 eye injuries and 41 people with permanent blindness, the 592 above were just the people specifically treated by the 12 Ophthalmologists

Hi, there is novel "blindness" by José Saramago (literature Nobel prize in 98). It's a story of ophthalmologist that encounter a blindness epidemic. I'd say that this book is not about blindness but human nature and epidemic is just a way to unravel it. Anyways, it was really weird to read that book during COVID. So many similarities. Thank you for your videos, I really like them.

Haven't seen Blindness in movie form, but I did like the book. Books usually get mutilated to be adapted to film, though. Loved the "the sun is not your friend" tangent lol

I saw totality in 2017 in NW Nebraska. I was wearing eye pro and had a camera with a sun filter. The filter could block out normal light and even bright light (same level as a welder's mask). The sun EVEN IN TOTALITY was punching right through the camera filter and I have a lot of great shots of it. But it was so bright that had I looked at the sun without the eye pro, I would have had eye damage, even then, it was bad. What is more dangerous is the edges of totality. When you are 90% totality either before or after totality you just get blasted.

Blindness was a Nobel Prize-winning novel by Jose Saramago before it was a movie. The blindness epidemic and the way humanity responds to it is a metaphor for the fragility of civilization and our base animal nature. I had to read it for my freshman college writing class, and I'd give it a solid recommendation. I can definitely see why ophthalmologists or blind people might object, but again, it's not "real" blindness.

Day of the triffids! Mass blinding event due to an astronomical phenomenon! Doubly relevant for this episode. Hopefully not the killer plant part, though

I had to schedule an eye doctor appointment. It was very stupid of me to call on the day of the eclipse - I was on hold for several hours!

The doctor (also ophalmologist) I worked for during my apprenticeship as a medical assistant always said: "Buckle Up, new years is coming. People will probably shoot stuff in their eyes again." That was our emergency day, the 1th of January. Especially dangerous: Champagne bottles. But I wonder, since the sun can increase the likelihood of a cataract, does the solar eclipse increases that likelihood even further? And uff, imagine someone has an iriditis and needs to use eye drops to widen it so it doesn't get worse...and with a widened pupil, they look into the solar eclipse...

Why would have thought that cataracts had an ever so slight silver lining?

The Expanse has a book / season on an alien world where a microorganism causes blindness in a group of colonists and researchers.

Blindness is from a book by Saramago! I would guess that is much better than the movie.

Can you do an episode on causes of retinal thinning?

Can we please have an episode on keratoconus? I'm a grad student and I just learned I need to go get checked for this and I'm overwhelmed and scared and I don't know how to find a doctor who specializes in testing for keratoconus.

That sounds familiar, I think he may have done it already. Check his video list for one on corneas.

Day of the Triffids, in addition to the walking killer plants has a mystery meteor shower that blinds everyone who looked at it. The two things aren't connected.

I'm not sure if this would be considered a mass eye injury event, but there is currently an ongoing lawsuit for patients who took a medication called Elmiron because it was found to cause a specific form of macular degeneration that is only seen in people who have taken Elmiron.

Got kind of a "mass eye" event example, though it's not as dramatic as wars or eclipses - in my environmental science classes, we covered GMO crops called Golden Rice, which were modified to have beta-carotene to help with eyesight-related problems in poorer communities. It's a topic that's a bit outside of the medical ophthalmology field, but it's certainly eyeball-adjacent! :)

Another fictional example of mass vision problems (not loss): In the 3-Body Problem book (and probably the show on Netflix too, but I haven’t seen it yet). A bunch of scientists wake up with a countdown in their visual field that they can’t get rid of. I won’t say why because of spoilers, but the protagonist visits an ophthalmologist who tells him it’s probably floaters (it isn’t).

Daniel Abraham's Long Price Quartet (a wonderful fantasy novel series) [spoiler alert] has a whole country blinded by magic.

An interesting case of 'widespread blindness' was 2,4-Dinitrophenol (DNP), which is a very efficacious weight loss drug with very dangerous side effects. It's apparently been linked to thousands of cases of blindness (also many deaths).

He addresses what I’ve been saying: Glaucomflecken is hard to say lmaooo. Dr Joe Corena Dr Eyecarrumba

I'm here for the sleeping pill. It's annoying when things get interesting and I'm trying to sleep. Love your skits, though.

Day of the Treffids has mass blindness as a key part of the plot.

I'd venture a guess that someone who's had cataract surgery with a replacement lens is probably at a similar risk for retinal damage as a younger person.

3:04 finally confirmed! Eyes=brain

⛔❓📵 How much are our screens (cell phone, laptop, tv, even to mention blue-screen) actually harming or rapidly permanently degenerating our eye health ?

There is a short story by G. K. Chesterton called The Eye of Appollo. It is not about mass vision loss, but the plot revolves around sun damage to eyes. Although after this video I realize it is not medically accurate.

Current mass eyesight loss event - happening right now (NOTE: this is not political commentary - this is purely based on data from people who have actually been there): Gaza (this year): multiple Canadian ophthalmologists volunteered to offer humanitarian aid. They recently returned to Canada and said they were haunted from treating dozens of severe eye injuries (and full eye removals) every day for weeks in children. Explosion shrapnel.

🤣🤣 Listening with sunburn....... the sun wanting to kill me, seems very real right now! 😂🥵☀️😖

Great sci-fi vision loss media... "the Expanse, Season 5" or Novel "Cibola Burn" an alien fungus growth that leads to blindness and the hero is the only one not effected bc he's on a high dose of cancer meds, great series!

@corawinterpaw9887

I think it's particularly interesting because the fungus doesn't damage the eyes. It just creates a light-scattering obstruction that eventually blocks out vision. The writers really put effort into not making the fungus malicious, and characterizing the blindness as just an unfortunate accident of two incompatible biologies interacting for the first time. Still almost kills everyone because they can't see the neurotoxic slugs, but that's a different problem :)

Thankfully I got my glasses a few weeks ago cuz HO! BOY! they are jumping in price now. Good thing they have the right filter. But I actually have a question about that. Cuz while doing my research, I saw one mention how apparently these kinds of glasses "expire" after 3 years. Is that true? Only way I can think of is if maybe the coating wears off? Also, I did see "Blindness". One of those movies I will never see again after it seared itself into my brain. Definitely one of those "humanity will lower itself to the worst of its desires when things go to crap" movies. Could definitely be triggering for some.

I have heard mixed things about the expiration of the glasses. The most believable things I have heard are 1) Most people are unlikely to keep the glasses in good enough condition to be undamaged and guaranteed safe over a long period of time (especially if they were the pair you unpacked and used), so better safe than sorry and advise replacement 2) research and innovation are happening constantly, so standards may update and thus people are encouraged not to cling to old lenses. I've seen conflicting reports on whether they deteriorate (maybe because of different manufacturing?), so it's probably more a matter of not being able to guarantee futureproofed safety.

@BlackTigr

@@FangzV I mean one report I've seen since said that the last time these kinds of lenses were updated, was in 2015. So the odds of them suddenly updating after all this time when there hasn't been any, are probably slim. And as long as you make sure they're not damaged in any way, they should still be safe to use. While I would like to use them for next time, I have heard about some organizations that want to collect them to send to South America for the one happening there later this year. If I'm able to find a collector for that near me, then I'd be fine giving them up for that and just buying another new pair for the next one.

Welp. Cases of eye damage from what I imagine were stubborn people that finally got told by the fed up ones around them, to go to the dang er, are now starting to roll in up here.

I’m 3 months in. My vision is good. Looked about 10 seconds. I looked away after it felt like laser went through eye to brain in left eye. The pain is insanely horrible. My eyes kill me and headaches. I got OCT after 46 hrs. Fine. Just saw another optometrist today. Not sure his test but it showed retina was ok. No clue what is causing the pain. Help. What’s going on?

❓Thank you for this Doctor, but did I miss it, what about "reflective" solar, like off the hood of your car? ‼️My Dad said when he was a kid (late 1930s) they used to have contests when all his friends would test each other as who could stare at the sun longer than everyone else 🙄🤪🥵 Does this scenario cause early onset glaucoma?

So, expanse spoilers warning but for another mass eye casualty event: During I think season 5 of the expanse (don't hold me to the exact season) everyone except one person goes blind from an extraterrestrial parasite on an alien world.
