Children’s Love of Video Games likely to Help Treat Vision Problems, especially Amblyopia

Amblyopia is usually treatable, but if left untreated it can affect a child's reading and fine motor skills, which can negatively impact academic success and self-esteem

Nov 18, 2016: Amblyopia is a Greek word that means “blunt vision.” It’s often called “lazy eye,” and is one of the most common vision problems in children.

Amblyopia is usually treatable, but if left untreated it can affect a child’s reading and fine motor skills, which can negatively impact academic success and self-esteem. Untreated amblyopia can also lead to blindness.

With amblyopia, one eye sends stronger electrical signals to the brain than the other one does. If untreated, the pathways the weaker eye uses to send signals can weaken further or fail to develop.

Doctors commonly treat the condition with a patch over the strong eye to force the weak eye to take over and develop the pathways to the brain. But this treatment may not make the eyes work together. A child may end up using one eye for distance vision and the other for seeing close up.

Researchers at the Retina Foundation of the Southwest in Dallas, Texas, wanted to see if they could improve on the standard treatment given to children with this condition.

“Amblyopia not only has deficits in vision, but it causes deficits in 3-D-depth perception, reading and fine motor skills,” said Dr. Krista Kelly, who led the study.

These deficits can last through adulthood. Without three-dimensional vision, a person’s ability to drive a car, read textbooks and generally see the world can remain impaired.

Game on iPad

Researchers gave children with amblyopia an iPad and a pair of glasses, and had them play a specially developed video game. The children ranged in age from 4 to 10 years old. The researchers also supplied glasses that changed the way the children saw things. The kids had to work the weaker eye harder in order to play the game, which also forced the children to work both eyes together.

Children with amblyopia in another group were given only eye patches. After two weeks, Kelly said, both groups were evaluated.

Kelly said the improvement between the two groups was pronounced. “We found that at the two-week visit, children who had the iPad game improved much more than children who patched.”

The children who played the iPad games had improved so much that the researchers gave the iPad and the game to both groups of children. After two more weeks, with both children playing the game, those who had started out in the eye patch group had caught up to the other group.

Kelly now wants to add new games, or even videos, and have the children play the games or watch the videos for more than four weeks. (VOA)

Aadhaar Helpline Mystery: French Security Expert Tweets of doing a Full Disclosure Tomorrow about Code of the Google SetUP Wizard App

Google comes up with a new feature

Google’s admission that it had in 2014 inadvertently coded the 112 distress number and the UIDAI helpline number into its setup wizard for Android devices triggered another controversy on Saturday as India’s telecom regulator had only recommended the use of 112 as an emergency number in April 2015.

After a large section of smartphone users in India saw a toll-free helpline number of UIDAI saved in their phone-books by default, Google issued a statement, saying its “internal review revealed that in 2014, the then UIDAI helpline number and the 112 distress helpline number were inadvertently coded into the SetUp wizard of the Android release given to OEMs for use in India and has remained there since”.

However, the Telecom Regulatory Authority of India (TRAI) recommended only in April 2015 that the number 112 be adopted as the single emergency number for the country.

According to Google, “since the numbers get listed on a user’s contact list, these get  transferred accordingly to the contacts on any new device”.

Google was yet to comment on the new development.

Meanwhile, French security expert that goes by the name of Elliot Alderson and has been at the core of the entire Aadhaar controversy, tweeted on Saturday: “I just found something interesting. I will probably do full disclosure tomorrow”.

“I’m digging into the code of the @Google SetupWizard app and I found that”.

“As far as I can see this object is not used in the current code, so there is no implications. This is just a poor coding practice in term of security,” he further tweeted.

On Friday, both the Unique Identification Authority of India (UIDAI) as well as the telecom operators washed their hand of the issue.

While the telecom industry denied any role in the strange incident, the UIDAI said that he strange incident, the UIDAI said that some vested interests were trying to create “unwarranted confusion” in the public and clarified that it had not asked any manufacturer or telecom service provider to provide any such facility.

Twitter was abuzz with the new development after a huge uproar due to Telecom Regulatory Authority of India (TRAI) Chairman R.S. Sharma’s open Aadhaar challenge to critics and hackers.

Ethical hackers exposed at least 14 personal details of the TRAI Chairman, including mobile numbers, home address, date of birth, PAN number and voter ID among others. (IANS)
