The FDA approved Second Sight’s “bionic” eye. While actually more of a retinal prosthesis, the implant is designed to assist patients with retinitis pigmentosa. The Argus II Retinal Prosthesis System has a resolution of 60 pixels. The device will not provide the HD type of vision that our eyes are capable of; however, more importantly, this technology will greatly aid a blind patient’s mobility and is a revolutionary step forward.
The system consists of a wireless retinal implant that rests on the retina. The patient will wear special glasses that see the image. The image will be sent to a visual processing unit that is worn on the patient’s hip. Once the data is processed it is sent back to the glasses which wirelessly transmit this data to the retinal implant. The implant electrically stimulates the photoreceptors simulating a coarse image. The patient learns how to interpret these light and dark images allowing them to navigate around and among obstacles.
The device was approved for use in Europe last year. Check out the video below from the European branch of the medical device company.
I saw this beautiful video from the PopSci RSS feed Sunday and wanted to share. The video is from The European Southern Observatory which operates four telescopes in the high plains desert of Chile. The visuals are spectacular. Watch it in full screen HD and you will be in awe of our gorgeous sky. Enjoy, you are in for a visual treat.
Today was floater day in the office. The most common questions today were all about floaters. The questions were centered around what do they look like, how do they start and what causes them. Not long ago I published in The Eye Doc blog an article about floaters but sometimes a picture is worth a thousand words. While researching for a future article I came across a very realistic video that does a good job simulating what floaters look like. By the way, most people have some floaters but not everyone has seen their floaters (and some people wish they had never seen their floaters).
If you want to see your floaters look up at the sky on an overcast day or at an evenly illuminated wall and you will most likely see those wispy cobwebs float by your vision. Check out the video below for a good representation of what a floater looks like. Most people don’t have as many floaters as is shown in the video but you’ll get the idea. If you want to learn more about floaters check out these articles I’ve written about them.
A new study just out showed that took a baby aspirin were twice as likely to have wet age related macular degeneration. The study did not show that the aspirin caused the macular degeneration and the authors did not recommend that patients stop aspirin therapy. Here is a good video discussing the study. Aspirin may be tied to vision loss
Love the video and love this song. Check it out and make sure you watch it in HD, full screen………. enjoy
Here is an excellent video on a mission trip from VOSH Indiana to Villanueva, Honduras. VOSH stands for Volunteer Optometric Services to Humanity. The Lion’s Club collects old eye glasses from doctor’s offices all over the US. These glasses are then catalogued and sent on mission trips with optometrists to underserved areas all over the world. This video shows what happens on a VOSH mission trip from the beginning to the end.
I was lucky enough to go on one of these trips to Costa Rica many years ago with VOSH Illinois, an unforgettable experience. I hope to go again soon.
