Seventy-year old Peter Marsh's vision has been declining since he moved to the Bay of Plenty from Auckland 18 months ago.
His loss of vision has been dramatic and only his peripheral vision now remains.
Mr Marsh's rapid loss of sight has nothing to with environmental factors, and everything to do with funding.
As reported in the Bay of Plenty Times Weekend, he and his wife, Margaret, were shocked to find out he does not meet the criteria to receive publicly funded Avastin injections in Tauranga for his eye condition - although he did in Auckland.
They were told he would have to pay almost $800 per injection out of his own pocket or get private health insurance which was unaffordable for the retired couple.
Mr Marsh is not alone. Eye Specialists ophthalmologist Andrew Thompson, who wrote a report on the issue, found access to publicly funded Avastin injections varied widely between health boards across the country.
