Smartphone photography helps eye disease diagnosis

Smartphone photography helps eye disease diagnosis | Technology | Scoop.it

A US team has devised a smartphone system for capturing high quality photos of retinas to help diagnose eye diseases. The cheap and easy-to-use system could bring the advantages of affordable telemedicine to ophthalmology clinics.


The researchers, from Massachusetts Eye and Ear, a teaching hospital of Harvard Medical School, describe the new system and how they tested it in a recent online issue of Journal of Ophthalmology.

 

The study evaluated the smartphone system's ability to capture photographs of the "fundus," or retina, in human and rabbit eyes.

The equipment comprises a smartphone running an inexpensive app and instruments that can be found in any ophthalmic practice.

 

Taking photographs of the retina is an essential part of any ophthalmology practice. But current methods rely on fundus cameras that cost tens of thousands of dollars.

 

Previous studies using Apple's built-in camera app in the iPhone have concluded its video capture is not good enough, as it cannot independently control focus and exposure during filming, which produces glare and results in poor images.

 

But the system the Massachusetts Eye and Ear team used overcomes this by using an iPhone 4 or iPhone 5 with a more advanced smartphone app, called "Filmic pro," which allows for independent control of focus, exposure and light intensity during filming.

 

They tested the smartphone's ability to capture retinal images with a 20D lens, with or without a Koeppe lens - a special dome-shaped lens ophthalmologists use to get a direct view of certain parts of the eye, for instance the chambers that are involved in regulating pressure in the eye.

 

By using the coaxial light source of the phone, this system works as an indirect ophthalmoscope that creates a digital image of the fundus

Technology is even helping with health care! I think it's pretty cool that you can use your smartphone to determine wether or not you have an eye disease, simply by taking a picture of your eye.

Talks about how smartphones are being used to detect eye diseases and how the iPhone 4 and 5 are not adequate in terms of their camera quality but with an application which allows own control of focus and exposure then it is successful. Chelsea Sanford

I think that's an awesome way to use technology! We can find new and faster ways to help find diseases which will help people with that disease.

Square is a device for electronic fund transfer. You just need to put in your Gadget and use Square- device for electronic fund transfer as simple as that.

Diana Ravestein's insight:

I think this square device that can transfer payments is a great technology advancement, because it makes it more convenient and eaiser for both the customer and the buisness. However, I feel like fraud could happen very easily when using the square since the transactions are held on a mobile device. I feel like it would make it easier for someone to steal peoples credit card information.

Diana Ravestein's insight:

I agree, I think students use techonolgy for more than just texting and social media. We also do some innovative stuff with our technology devices as well. Like the article said, some students use their cell phones for alarm clocks to wake them up for school in the morning, watch educational videos online, use the calander app to help keep their daily schedules oranized, and much more.

WOW!!! so very interesting!!!! well you see, my school just got us sum computers so we use those !!!!!! that shows that students really use technology a lot and maybe it should kinda not take over our lives so much!!!!!!!!!!1

Three Ways to Improve Your Android's Lock Screen Security

Three Ways to Improve Your Android's Lock Screen Security | Technology | Scoop.it
Sure, Android users don't have fingerprint scanners (well, maybe one), but that doesn't mean you're stuck when it comes to security. Here are some of the best apps you can download to boost security on your phone without buying all-new hardware.

Via Amigo Omega
Diana Ravestein's insight:

I think this is important because if you have a cell phone with personal information on it you wouldn't want someone to be able to get on to it and read it or use it. So having a passcode is important, and I think Andriod improving their passcode security is a smart idea. It makes it much harder for someone to hack into your phone.

This article is really interesting to read! If we could make touch screens that charged using the energy from the touch of your finger that would be a huge technology advancement! Your smart phone, ipod, ipad, ect would charge the more you use it...that means you wouldn't have to plug your touch screen device into the wall and wait hours for it to charge ever again.

Don’t Be Let Down By Technology | Technology | Scoop.it
Stop for a second, and imagine what your job would have looked like 150 years ago. Before the telephone, email, internet, video conferencing and all the other tools we now take for granted, how would you have performed your job?

Via Thomas Faltin
Diana Ravestein's insight:

I think this article is important because it helps us realize that the world got along just fine before technology came along, and now that technology is here we rely on it so much. At any given moment it could break or shut down and we could lose it all. If it technology were to fail we would lose so much, such as important documents, pictures, videos, and more. I think the problem is we put too much trust in technology.

Electrolux HandCleaner

Electrolux HandCleaner | Technology | Scoop.it

Electrolux HandCleaner was designed based on the technology of luminous plasma gas, also used in TVs and electrical lamps.

By an electrical stimulus the same plasma gas can also be used to clean the hand’s impurities, through a combination with the existing gases in the atmosphere.

Due its rechargeable battery, the HandCleaner can be used multiple times during the day.

The device is made of a polymer body and activation of the systems is by touch.

The electrical current and creates the plasma. This plasma reacts with oxygen, nitrogen and water steam – found in the air – to destroy bacteria, fungi and viruses without harming your skin.

Electrolux HandCleaner is the intelligent mobile solution for sterilization of hands.


Via Deloste
Diana Ravestein's insight:

I think this is a really neat technology advancement. It saves you time because it makes it quicker to wash your hands and they come out even cleaner then they would if you were to wash them with soap and water. Also, it helps to eliminate the waste of water! This is important because eventually over decades we will run out of clean water. So creating technology like this can help conserve water for a longer period of time.

Diana Ravestein's insight:

I think this artical is interesting because it explains how technology is increasing and advancing so quickly that in the near future it may start to replace humans. If It replaces humans, many people will lose their jobs. This isn't a good thing because the emplyment rate in America is already pretty low, and we don't need it to be any lower. So I feel like technology is advancing almost too much to the point where it is bad for our economy.
