Yellow eye in photo?


karen_thirlaway

Recommended Posts

I have been using my iPhone to take photos which I think may have a problem with the type of flash is uses, but almost every photo I take

of my son brings out a yellow glow in his eye, Iv not seen this in anyone else Iv taken photos of. On recommendation I took him for an

eye test which was fine so was wondering what else could be causing this to happen? Could it be a fault with the camera, or can the

flash do that to certain people? All my photos are being ruined, thanks for any help x

<p>Karen, I hope someone comes up with a camera or flash problem.<br /> You may want to get a second opinion from another doctor or double check with the doctor that you already saw, if it is not equipment related.<br>

I did a quick google and found this.<br /> One early warning sign of Coats’ disease is yellow-eye in flash photography. Just as the <a title="Red-eye effect" href="http://en.wikipedia.org/wiki/Red-eye_effect">red-eye effect</a> is caused by a reflection off blood vessels in the back of a normal eye, an eye affected by Coats’ will glow yellow in photographs as light reflects off cholesterol deposits. Children with yellow-eye in photographs are typically advised to immediately seek evaluation from an <a title="Ophthalmologist" href="http://en.wikipedia.org/wiki/Ophthalmologist">ophthalmologist</a>, preferably a vitreo-retinal specialist. Coats’ disease itself is painless. Pain may occur if fluid is unable to drain from the eye properly, causing the internal pressure to swell, resulting in painful glaucoma. <strong>MORE-</strong> http://en.wikipedia.org/wiki/Coats%27_disease</p>

<p>An ophthalmologist is a specialist in medical and surgical eye problems. I don't want to worry you but you need to find out for sure. Would the optician be able to recognize this disease? That is why I suggested calling him asking him about it. I did not search much after I found that Wiki link but I could not find any other links about humans with yellow eyes from flash. There were some with animals and yellow eye. If it is Coats' then it could be serious. Make sure to read the link.<br /> If you google Coats' disease and look at the images there are a few samples of young kids with the yellow eye and it is usually one eye. See link below.<br /> http://www.google.com/search?q=Coats%E2%80%99+disease&hl=en&client=firefox-a&hs=JPI&rls=org.mozilla:en-US:official&prmd=imvns&source=lnms&tbm=isch&ei=Kr08T9zDMMOI2gX49a2yCA&sa=X&oi=mode_link&ct=mode&cd=2&ved=0CAsQ_AUoAQ&biw=1282&bih=622<br>

Please read this- <strong>I Discovered My Son's Eye Disease in a Photo-</strong> http://www.momlogic.com/2010/02/my_kid_contracted_coats_disease.php</p>

<p>I certainly hope I am wrong and it is just equipment problems.</p>

<p>I'm still hoping that someone comes up with an equipment issue but you said this is not happening with anyone else you have taken photos of. Do a search for iPhone yellow eyes etc...<br>

Have you taken flash photos of other people after your son started having the yellow eye pix? If not then you may want to test some people. But I would certainly call that optician regarding your concerns.</p>

Optician = specialist in making and fitting corrective lenses

 

Optometrist = specialist in measuring visual acuity and prescribing corrective lenses (which are then made by a

dispensing optician)

 

Ophthalmologist = a medical doctor specializing in the diagnosis and treatment of eyes diseases and injuries

 

To the limited extent of their abilities, opticians and optometrists who suspect a problem requiring medical treatment have

a duty to refer clients to an ophthalmologist for diagnosis and treatment.

<p>Not to worry, the problem is; tiny cameras with flash. I am sure you have noticed that when driving at night, animal eyes caught in the headlights of your automobile, glow yellow. In addition, modern highway signs glow brightly when the headlights play on them. Both the eye and the glass bead that makeup the signs are super reflectors of light, under certain conditions.</p>

<p>When light enters a sphere, the light energy reverberates around inside the sphere and a high percentage exists. Now the exit path from the sphere is nearly identical to the entry path. Translated, this mean, in the car, you see glowing animal eyes because you are sitting very near an imaginary line, headlight-to-eye. Same with tiny cameras, the flash mounted close to the camera's lens and this positioning almost always yield a phenomenon called "redeye".</p>

<p>Both the animal eye and the human eye are made-up of transparent tissue. At the back of the eye is the retina with its light sensitive nerve cells. The retina is rich with blood and the retina contains pigments (dye) that enable color vision and increased sensitivity in dim light.</p>

<p>While redeye shows up red most of the time, it can be yellow depending on conditions. You might notice that professional photographers often use a hand-held flash, held at arm's length. The idea is to get as much separation between lens and flash as possible. Many cameras have tricks up their sleeve to minimize redeye. Some fire off a pre-flash just ahead of the main flash to cause the Iris of the subject's eyes to reduce in size, this minimizes redeye. Many cameras and viewing software feature a redeye fix. Software can seek out redeye and make adjustments to cause the eye to appear normal.</p>

<p>Alan that is a pretty bold statement "Not to worry". </p>

<p>The OP CLEARLY states "I think may have a problem with the type of flash is uses, but almost every photo I take of my son brings out a yellow glow in his eye, Iv not seen this in anyone else Iv taken photos of" in the original post. It ONLY happens with her son. I know as a parent of two young children, I would definitely follow up with a specialist just to be safe.</p>

<p>I truely hope it is nothing but Karen, please keep us informed of what the doctor finds.</p>

<p>Alan M: This is a potentially very serious matter for the OP and her son. Don't give advice on a topic in which you are obviously clueless. For example, your example of light "reverberating" in a sphere doesn't happen in eyes and is not the cause of red eye, eyeshine and related effects. </p>

<p>If it IS the flash close to the camera a simple test is to take a photo with the child looking at the camera while another camera or flash unit from the side provides the illumination.<br>

If the camera with child head-on has slow shutter speeds one uses that and with a countdown system the other person fires their flash while the shutter is open.<br>

If the problem remains then I would suspect a health problem.</p>

<p>Thank God! That's absolutely wonderful news! Given your observation that this effect doesn't happen with anyone else, that must mean there is something different about the anatomy or chemical composition of parts of his eye, but fortunately, nothing to worry about. Phew! Now you can relax.</p>

<p>Best regards,</p>
