Retinitis Pigmentosa & Gene Therapy

There have been a couple of promising trials published this week on the treatment of Retinitis Pigmentosa using gene therapy.

One team in Pennsylvania  managed to prevent or even reverse this blinding condition in a dog, while a Florida trial has succeeded (in animals so far) to deliver the altered genes via a virus, and show that they go and have the desired effect in the area required.

Human trials are still some way off, but there is hope for RP sufferers and their families in the future.

A bad week for Aspirin?

Two reports this week have suggested that Aspirin may not be such a wonder drug after all.

One report published in the Jan 2012 issue of Ophthalmology indicated that regular Aspirin use may double the risk of Age Related Macular Degeneration (ARMD), and that  there is an indication that the more frequent the use, the more severe the ARMD. More investigation needs to be done on this, but for the moment, there is a suggestion that Aspirin use should be reconsidered in people who already have ARMD.

Another study published in Jan 2010, in The Archives of Internal Medicine suggests that Aspirin is not so effective in preventing CardioVascular events as perhaps initially thought, likewise it may not have the preventative cancer protection suspected, but definitely increased the risks of “non trivial bleeding”.

It may be worth asking your General Practitioner if this is of concern…

MGDRx Eyebags back in stock

MGDRx EyebagAfter some delay, we now have the highly effective MGDRx Eyebags back in stock. These are an excellent treatment for many eyelid conditions, and can be very useful to help most causes of dry eye. Compared to the cost of regular use of artificial tears they are also very cost effective, and treat the cause of the discomfort rather than the effect.

Driving Sight Tests

In late December the RSA wrote to all “stakeholders” regarding the new standards required for driver’s vision. These new tests have been hurriedly implemented, and apparently without enough though put in to which tests would be recommended or acceptable, and what would be the pass mark! Optometrists, as recommended by our Association have implemented these new standards, as far as possible at least, until further clarification allows the full testing to be done.

Some GPs, as recommended by their professional body, The Irish College of General Practitioners, continue to perform the driving sight test to the older standards. The main issue to us is that the new standards involve a full eye examination plus further testing, which is obviously time consuming to check, and therefore more expensive for our clients than the old test. We are obliged to do the new tests this way- we are bound to do what is recommended as best practice by our professional body- the Association of Optometrists.
