Marion Lindsey-Noble faced paying for treatment in Devon

Marion Lindsey-Noble, who lives on the counties' border, was treated for age-related wet macular degeneration.

Devon war veteran Jack Tagg was told he could only have treatment for the same condition if he went blind in one eye.

Mr Tagg's MP, Torbay's Adrian Sanders, condemned such discrepancies across health trusts.

There is something wrong with how different PCTs are interpreting one set of guidance Adrian Sanders MP

Age-related wet macular degeneration (AMD) is the most common cause of blindness in the UK.

AMD can lead to blindness in as little as three months, but it can be reversed with prompt treatment.

A doctor at the Royal Devon and Exeter Hospital told Ms Lindsey-Noble she could have an injection of Lucentis to treat her AMD if she paid �850 each for monthly treatment.

But at Musgrove Park Hospital in Somerset, the treatment was given to her free.

She said: "My father had wet macular degeneration in both eyes and I saw how miserable his last 10 years were."

Jack Tagg, an 88-year-old wartime pilot from Torquay, said he was told by a consultant in Torbay that he would not get Lucentis injections unless he had lost vision in his left eye.

Jack Tagg is selling his home to fund his injections

He has now started a course of private care using Avastin, which costs �715 per injection, and is selling his house to fund it.

Adrian Sanders said such situations were unfair.

He said: "Clearly there is something wrong with how different PCTs are interpreting one set of guidance from government."

Somerset Primary Care Trust said patients who met criteria drawn up by local consultants were funded for Lucentis.
