Weekly Glance for January 14th

What's new in optometry, week by week.


New FDA approval: EyeBOX.

What is it?
The first noninvasive test to help diagnose a concussion.

How does it work?
The patient watches a four minute video while the software analyzes their eye tracking. The clinical trial showed a noticeable difference in eye movements between normal patients and those with brain injuries. Here is a picture of the device.

How does one diagnose a concussion?
There isn't a good objective way nor is there a good way to quantitatively measure if a patient is getting better or not. The research team states because the EyeBOX gives an actual scored report, it can be used to monitor improvement over time.

Why is it important to detect a concussion?
For a variety of reasons but one of them is second impact syndrome or "SIS". SIS is "a rare but serious condition in which a second concussion occurs before a first concussion has properly healed, causing rapid and severe brain swelling."

Here is a TEDMED talk by the neurosurgeon that co-founded the company.


The blue light debate lives on.

A new study found that a blue-blocking filter was no more effective than a neutral-density filter for reducing digital eye strain. 

Tell me about the study.
The study asked 24 subjects to read a cognitively demanding reading task on an iPad for 30 minutes. They did it twice, once with a blue-blocking filter (blocking 99% of blue light) over the screen and then again 24 hours later with an equiluminant neutral-density filter (blocking 50% of blue light) over the screen (not necessarily in that order). After the reading assessment, the subjects answered a questionnaire which gauged their level of fatigue and eye strain.

What did they find?
Eye strain and fatigue symptoms were similar regardless of whether the patient was looking through the blue-blocking filter or neutral-density filter. The authors acknowledge some limitations in the study however, they state, "further research into the efficacy of blue-blocking filters is required before they can be advocated as a treatment for digital eyestrain."

Can I check my PD with my smart phone?

Soon. EyeQue, developer of an at-home eye test on your phone just got funding on Kickstarter for their PDCheck app.

How does it work?
It requires a selfie while wearing their special glasses and the app. They are able to accurately measure the PD by using the markings on the frame. 

How much is this?
The app is free but the frames will be $12.99. The app, which doesn't work without the frame, is expected to be available next month. (via)


Note to self: Vitaros and VitA-POS treat very different things.

Turns out, not a real thing
Done! Congratulations on being all caught up!
See you next week!
