Good start to 2010

By Sharon Siddique
MDS President


On Saturday afternoon, March 27, 2010, about 50 MDS members gathered at the Auditorium at MD 11 at NUS. I think we were all pleasantly surprised at how easy the venue was to locate – a short walk from the main entrance to NUH.


Our first event of 2010 was a great success! Associate Professor Caroline Chee, Senior Consultant Ophthalmologist and Head of the Vitreoretinal Service at NUH, spoke on “Advances in the Treatment of Macular Degeneration”.


Prof Chee began her lecture by zeroing in on the retina. She then gave a very clear explanation of various eye diseases involving the macula, particularly AMD and MMD. Her descriptions included the types of treatments available for various conditions, and also stages of degeneration.


Personally I found her explanation of the very important group of Anti-VEGF drugs most interesting. As a class of drugs, they are useful in stopping the growth of new blood vessels, reducing swelling, and preventing bleeding. They including Lucentis and Avastin, as well as a new (still experimental) drug called VEGF-trap. Injected directly into the eye, they are particularly effective when bleeding occurs.



The Q and A session further demonstrated what useful insights Prof Chee could share with us. Her candor and caring attitude were much appreciated by all present. We rounded out the afternoon with a tea break and networking session. And Prof Chee was the last to leave! Thanks from all of us, Prof. Chee!

Shuttle Bus to NUH

Members can head to NUH by taking the free NUH shuttle bus from Dover MRT station. It leaves the station every 15 minutes on Saturday.

But the last bus is at 2pm, so the shuttle will not be available for the return trip from NUH to Dover MRT station.

Blind soldier 'sees' with his tongue

A British soldier left blind by a grenade in Iraq has told how his life has been transformed by ground-breaking technology that enables him to “see” with his tongue.


Lance Corporal Craig Lund
berg, 24, can read words, make out shapes and walk without assistance thanks to a device developed in the United States which could revolutionise life for other blind people.

Lundberg, from Liverpool in northwest England, completely lost his sight after being struck by a rocket-propelled grenade while serving in Basra in 2007. Faced with a life of relying on a guide dog, he was chosen by the Ministry of Defence as the first person in Britain to trial the BrainPort device, which could revolutionise treatment for the blind.

It converts images into electrical pulses which are sent to the tongue, where they cause a tingling sensation. The different strength of the tingles can be interpreted so the user can mentally visualise their surroundings and navigate around objects.

The device consists of a tiny video camera attached to a pair of sunglasses which are linked to a plastic “lollipop” which the user places on their tongue to read the pulses. The image is created by presenting white pixels from the camera as strong stimulation, black pixels as no stimulation, and grey levels as medium levels of stimulation, although interpreting the images takes intensive training.

“It feels like licking a nine volt battery or like popping candy,” Lundberg explained Monday. “The camera sends signals down onto the lollipop and onto your tongue. You can then determine what they mean and transfer it to shapes. “You get lines and shapes of things. It sees in black and white so you get a two-dimensional image on your tongue – it’s a bit like a pins and needles sensation.

“It’s only a prototype, but the potential to change my life is massive. It’s got a lot of potential to advance things for blind people.”

Thanks to the device, he can now “pick up objects straight away. I can reach out and pick them up when before I would be fumbling around to feel for them.” Lundberg and British military surgeons have visited the US for training in how to use the device, which is being developed by a team led by Gale Pollock, a former major general in the US army.

It is hoped that with further refinement, the BrainPort could be used for other blind British military personnel. However, the future of Lundberg’s trusty guide dog seems secure for now. “There is no way I’m getting rid of my guide dog Hugo, though – I love him. “This (the BrainPort) is another mobility device, it’s not the be-all and end-all of my disability.”- AFP
