DLA and severe visual impairment

Hoping people realise just what a can of worms this may open for both DLA and PIP from 2 angles:

1) The idea that a Snellen test carried out in allegedly perfect conditions may give inaccurate readings opens up many cases across many visual impairments. The RP in the case in question will be very much the tip of the iceberg. Any visual impairments which involve sensitivity to light, movement, colour etc. will throw up the same issues. Hardly news to anyone who works with people with a VI but probably a bit of a shock to people who take such tests as written and think they have some merit.

2) I’ve always been fascinated by this one anyway in as much as the DLA regs. enshrine into law concepts around registration which have only ever been guidance. To be registered you do not have to fit those criteria exactly so the DLA regs. provide a definition that is tighter and more prescriptive than the registration criteria. It strikes me that at some point there has to be a challenge on this.
