WGD: Glaucoma Vision

An eye-catching simulation of vision through an eye with advanced, early, or no defects from glaucoma, together with a short explanation of the brain's visual processes leading to these perceptions (submitted by Dr A. Hoste from Belgium and prof. A. Safran from Switzerland)

Glaucoma Vision
A short explanation on the way the brain perceives images from eyes with glaucomatous damage
The images represent the visual field of a left eye. The corresponding results of the visual field test (where blind areas are represented in black) are embedded in the images. A normal test always shows one blind spot: where the optic nerve is attached to the back of the eye, there is no retina and consequently no light perception. Yet, we do not perceive this blind spot because our brain is able to fill it in with colours and patterns from the surrounding areas. The brain uses visual information received from adjacent parts of the image to achieve this.
In the same way, the brain conceals damage caused by glaucoma. In the image representing an early stage of glaucoma, the eye looks to the fixation point in the centre. It does not see the children because they are practically completely located in the blind area. Still you are unaware of any visual problem, due to the filling-in process. Even in a later stage of the disease, the brain is still able to compose a plausible image. The deformations in the periphery remain unnoticed because you are unable to fix your eye on them. You are always looking at the centre of the image, and when you shift your gaze to the periphery, the deformations move with it.

"If detected early, and controlled, it should not affect a person's work life," said Prof Aung.
The lack of public education has prompted organisers of the first World Glaucoma Day, held worldwide tomorrow, to reach out to the public, with talks at venues such as the Alexandra and National University hospitals and the SNEC.

The NUH-GPAS World Glaucoma Day Public Forum at the Central on 8th March 2008 which attracted close to 350 people is one such collaborative efforts between hospitals and patient support groups for increasing awareness of glaucoma to the public and sufferers.
On 29th March 2008 the Glaucoma Patients Association will assist the National University Hospital, Department of Ophthalmology where over 250 pairs of eyes would be screened.

Another hospital, the Tan Tock Seng Hospital collaborated with the Glaucoma Society (Singapore) where 325 people were screened for signs of glaucoma.

Other talks and eye screenings were conducted by the Singapore National Eye Centre, Alexandra Hospital and the Jurong Medical Centre.
