Recent trials studying the effect of radiation therapy on the macular area show promise as another method of treating neovascular (Wet) Age Related Macular Degeneration (AMD). The two methods which have been looked at differ significantly in the way they deliver the radiation.
The method which hit the news in the last few weeks uses the IRay machine, a low voltage xray machine which delivers xrays to the macular area through three beams which are shone into the eye through the lower sclera (white of the eye). One of the first studies from Mexico reported that over 12 months, patients treated by this method required less anti vegF injections than the control group. This could mean that treating AMD may be cheaper in the future, and hopefully therefore treatment may become more widely available.
More information on the AMD treatments are available on this page, and the Mexico study mentioned is available to . (You will need to login or register (free) to see it.
Update – that link no longer works, but if you are interested there is an article here about the safety and efficiency of the treatment. Again, you might need to login or register to read it.
Researchers have recently begun trials to investigate the safety of a stem cell derived treatment for Age Related Macular Degeneration (AMD, ARMD). The treatment involves implanting replacement retinal pigment epithelial cells derived from human embryos. Already there has been some success, with both subjects reported on experiencing an improvement in vision. The trial is continuing, with more subjects being treated. The main aim at the moment for this trial is to determine if this way of treating ARMD is safe- stem cells could differentiate into any cell type, so there is a risk of a type of tumour called a teratoma, though as the researchers have implanted cells which have already been differentiated (they have already been told to be Retinal Pigment Epithelial (RPE) Cells), hopefully this risk will be minimal.
If successful, this treatment will be most useful to prevent damage to the retinal photoreceptor layer. The photoreceptors require support from the RPE, and become damaged after the RPE becomes damaged. Therefore this treatment may in future be a preventative, but may restore some function in more advanced cases.

New research indicates that Grapes are the latest food to be found to help prevent Age Related Macular Degeneration (ARMD or AMD).
Superfoods such as blueberries, pomegranates, spinach and broccoli all confer protection because they are rich in anti-oxidants, but now grapes may be added to the list- they have been found to be as effective as lutein supplements in ARMD prevention!
A balanced diet is proving to be one of the most effective preventatives of ARMD, and while dietary supplements have been proven to be very successful, perhaps those with a very good diet would not have the problem and therefore not require the supplements?
