What is the probability that a sighted dog has the gene for blindness if after crossing with the same dog one blind puppy was born
Answers
Answer:
The experimental treatment is the first to reverse blindness and restore sight to dogs diagnosed with SARDS. The treatment restored sight to the two dogs that were treated on April 12 and April 27.
"This is the first small sign of hope that actually something can be done," Grozdanic said.
The dogs were treated with intravenous immunoglobulin (IVIg), a human blood product that contains antibodies from the plasma of thousands of blood donors. It is used to treat immune deficiencies, inflammatory diseases and autoimmune diseases.
"Although the dogs won't be catching any Frisbees, they can navigate and not bump into objects," Grozdanic said.
SARDS was first identified in the 1980s and blinds as many as 4,000 dogs each year in North America, he said. The dogs have a sudden loss of vision despite no structural changes to the eyes or damage to the retinas in the early stages of the disease. Their eyes appear completely normal, but their retinas show no electrical activity.
