will develop a serious eye infection. The day after the injection your eye should be comfortable, there should
be very little pain. If your eye starts to get red, with misty vision
may be no pain ), perhaps 2-5 days after the injection, you should
suspect an infection and attend your eye department urgently. In Birmingham
this is the Birmingham
and Midland Eye Centre Casualty at the

We can collect and store DNA samples indefinitely, until we have enough to start the active research. Once we have samples from enough dogs, we analyse their DNA with about 170,000 different markers located along the DNA, to hopefully identify regions of the DNA that are similar in the cases and different in the controls; such a region is very likely to harbour the causal mutation. The dog’s genome consists of around two and a half thousand million ( x 109) nucleotides of DNA. If each nucleotide was 1mm long the canine genome would stretch from Land’s End to John O’Groats and back again. A mutation that is responsible for an inherited disease can be anywhere in the DNA and can be as small as a single incorrect nucleotide, so pinpointing a disease-associated mutation can be quite a challenge. Once we have identified a region (called the ‘critical region’) of the DNA that contains a mutation (equivalent to a one or two mile stretch of road on the journey from Land’s End to John O’Groats and back) we ‘zoom in’ on that region and sequence some or all of the DNA within the region, nucleotide by nucleotide, until we identify the mutation that is causing the disease we are investigating. Once we have identified the mutation and confirmed we have the correct mutation, by analysing the DNA from a large number of cases and controls, we develop a DNA test that is offered to the public by our DNA testing facility.
