Placing a patch over the eye following treatment is a recommended procedure. It protects the eye from sunlight and keeps flies away from the eye. This should have benefit in decreasing the spread of the disease in the herd.
Sometimes outbreaks of pinkeye are so severe that whole herd treatment should be implemented. Typically when more than 10-20% of animals in a herd are affected, it is beneficial to treat all cattle with an injectable antibiotic. If fly control is not adequate, an extra application of treatment that will remove all face flies is very highly recommended.
Timely and appropriate treatment of cattle with pinkeye will pay dividends in terms of preventing gain losses due to the disease as well as decreasing the permanent damage to eyes which will decrease their value.
