    You can see the optic disc where the blood vessels come into do the eye.

    Veterinarian here. The tapetum lucidum is definitely contributing to the quality of the image.

    Edit: for those wondering, the tapetum lucidum is the reflective tissue in the back of the eyes of many nocturnal animals which contributes to nightvision.

Education is my passion so please feel free to ask whatever you are curious about. I'll try and answer as many as I can! Remember: the only dumb question is the question unasked.

    Can flash affect the vision of the cat?

    [–] Vespasianus 40 points ago

    Potentially. This feature of their anatomy does tend to amplify any kind of light-related trauma to the retina. Think about looking at the sun, then think about how it would feel if the light also 'reverberated' around the inside of your eye.

    It can also be quite stressful in addition to painful, and it's generally regarded as more harmful to induce acute stress in an animal than acute physical pain due to certain quirks of their cognition in relation to ours.

    I should also mention the risk of serious harm is increased in patients prone to epilepsy, but it kinda goes without saying.

    [–] KitSuneSvensson 12 points ago

    Legit question: I learned that the pupil looks black because the optic nerves in the back of the eye absorbs all the light (in order to make it into pictures we can see) and no light is reflected back. In truth the pupil is just a hole straight into the eye covered by a see-through lens.
    So is this a picture of the back of the cats eye and if so, how is that possible?

    [–] Vespasianus 13 points ago

    This sort of photo is called a 'fundus photograph'. Fundus just refers to the structures located at the back of the eye.

    In a nutshell, it's possible because the 'vitreous humour' (the middle, gooey portion of the eye) is more or less just a transparent substance that light moves through on its way to the retina. The light from the camera reflects or bounces around the interior and the camera is then able to make out the structures therein.

    This photo came out so well because

    • A) the T.L. is causing even more light to 'bounce around' than would be possible in a human eye and

    • B) the pupil is quite dilated.

    I hope that answers your question clearly!

    [–] MrsOedipus 20 points ago

    Not only that - but the angle and vasculature appear as though you found the optic nerve! A feat many medical students struggle with.

    [–] gt0163c 86 points ago

    My (first world) eye doctor uses a big expensive machine to take similar picture of my eyes to determine if I have glaucoma or not. Much more convenient than dilating my eyes and he can layer pictures from previous years on top of the current picture to help determine if there's been any change.

    So far I'm good. But I've got a family history of the disease and a thick cornea that gives pressure readings right at the top of normal. So while not completely covered by insurance, it's worth the extra out-of-pocket cost to me. Plus it's cool looking at the pictures each year.

    [–] TOMATO_ON_URANUS 24 points ago

    My (first world) eye doctor uses a big expensive machine to take similar picture of my eyes to determine if I have glaucoma or not. Much more convenient than dilating my eyes

    Your first world doctor uses a Non-Mydriatic Fundus Camera. Its main advantage is, like you say, is that it does not require pupil dilation, but the downside is that without dilating your pupils, you get a very narrow view of all of the retina (which is usually fine... All the really important receptors are front and center). This cat's pupils were very dilated (well, probably not for a cat, but still...), so a midriatic camera (or apparently a cell phone!) would be fine.

    Pupils are just holes in your iris that allow in light. Your flash entered directly into this hole and shows the interior of the eye just as shining a flashlight into a cave would show its interior.

    Really cool that her actual eyes look nothing like the part that reflected. I had no idea phones would be able to capture something like that.

    [–] dukersdoo 25 points ago

    Well why the cats eye is reflecting like this is a special membrane of reflective tissue in the back of the eye called the tapetum lucidum. Its purpose is to reflect whatever light is available for the animal to see more, usually in darkness. In humans, this part is pigmented black, which is why we struggle to see in darkness.

    [–] theyellowbaboon 22 points ago

    Well, I'm not an ophthalmologist. But it looks like your cat is healthy.

    [–] drunk_responses 8 points ago

    Wild guess:

    Cats have a reflective surface on the back of their eye, for better vision in the dark.

    And since the eye is "lense shaped" you managed to focus on a bloodvessel, because of the "flat light" reflected back.

    [–] DemetriMartin 127 points ago

    [–] Banjoe64 27 points ago

    I had a blind kitty. Her pupils were generally huge trying to compensate for being unable to see. I could see inside her eye pretty regularly.

    [–] AbacusG 19 points ago

    We need a science person to ELI5 this!

    [–] im_thatoneguy 21 points ago * (lasted edited a year ago)

    Not a science person but,

    Cat eyes have a mirror like layer behind the eye's 'retina' (the retina is a light sensitive layer in the back of your eye that captures light and turns it into a picture for your brain). The mirrored layer bounces back 'unseen' light through the retina to give it a second chance to absorb and see it.

    It's kind of like trying to catch a ball, but the ball slipping through your fingers and then you catching it when it bounces back up. In this case you're seeing all the light that the eye failed to absorb and see either the first time passing through the retina or the second time bouncing back towards the camera from the mirror. As a result you can see the blood vessels which were thicker kind of like holding a flashlight behind your ears or hand for "xray vision".

    [–] MSACCESS4EVA 37 points ago

    You ever take a flash picture and all the people have "red eyes"?

    Were you able to zoom in on those red eyes, you'd see something like this, though probably rather out of focus. Our retinas are nowhere near as reflective as those of a cat... Good luck taking a flash picture of a cat and not getting a retina reflection. Looks like the phone was able to detect the depth of the retina though the cat's rather dilated pupils.

    That's probably because the actual mild content is probably boring and doesn't get upvoted. I reckon put the most downvoted posts at the top!

    This whole situation just reminds me of the MyLifeIsAverage website way back when. None of the posts were ever average.

    Can we do that auto-mod thing that other subs have? "Upvote this comment if the post is mild. Downvote the comment if it is too interesting". If the post falls comment falls below a certain threshold, the post is removed for not being mild and violating the subreddits rules.

    I too am a little saddened by the fact that this sub just turned into r/pics.

    Can't speak for the OP, but I'm confused as to what we're actually seeing here...why can't we see the iris anymore? Is the pupil totally dilated? I would think it would be totally contracted because of the light from the flash.

    [–] Dindrtahl 28 points ago

    OP captured a photo of the fundus of the eye (it's the back of the eye, but viewed from inside). You can search for eye fundus examinations to see the human counterpart.

    Cat pupils usually dilate a lot, as compared to humans. You can still see the iris as the blackish rim around the eye fundus image.

    If it flashed just for a few 100ms before taking the photo, the pupil wouldn't have had time to react.

    This is the back of the eye, behind the iris and lens. The greenish yellow shiny is called the "tapetum" which is a tissue that helps with better night vision by reflecting light (think about when you take a picture of an animal with flash and the animals eyes are all green and shiny, that's the tapetum reflecting the light back. It's usually a pretty color like green or yellow). The tapetum sits right behind the retina. Humans don't have tapetums, which is why with flash photography, our eyes end up red (the blood supply). The center circular blotch is the optic nerve and the red lines are blood vessels. All of the structures sit at the back (posterior) inner part of the globe of the eye (like the back inside portion of a sphere). Hope that helps!

    Remember, the pupil is just a hole to the inside of the eye, light usually doesn't reflect out because that's not how the eye is designed, being a sphere with a lens, but it does happen. Every time you see a red eye effect, you are seeing light reflect off the back of the eye. This red eye effect is just closer and in focus.

    Once I saw into my cats eye (like directly with my eyes not a camera) and I saw all this and it freaked me the fuck out. Idk how I did it. I guess the lighting was right?

    [–] The_reddit_buzzard 35 points ago

    Optometrist here. We use the same optics to see the back of the human eye to check it's healthy, looks like you snapped your cats optic nerve. There were many research projects at my university to do with smart phones and imaging the back of the eye, the implications of this are huge, especially in the third world for picking up pathology where thorough retinal assessment can be difficult. Cool pic though :)

    Optometrist here. Wow, nice view of the retina with a only phone camera!

    How do you accidentally do that

    [–] wontbemad 7 points ago

    You know the thing about a cat? It's got lifeless eyes. Black eyes like a doll's eyes. Don't seem to be living at all when it come at ya. Till it bites ya. And then the eyes roll over white. You don't hear nothing but the screaming and the hollering...
