==Diagnosis==
''Blue-eyed disease'' can be diagnosed by a combination of history, above clinical signs, serology, lesions and virus isolation.
A week after infection a serological response can be seen using a virus neutralization test and 2 weeks later with a haemagglutination inhibition test.
The diagnosis can be confirmed using virus isolation on PK15 or primary pig kidney, using samples from infected tonsils, brain or lung.
On post mortem all age ranges have corneal opacity which is mainly unilateral. Piglets show evidence of mild pneumonia, distended bladder and stomach, fibrin strands in the peritoneal cavity and congestion in the brain. Growers show kidney and pericardial haemorrhages aswell as brain congestion.
'''Differential diagnosis''':PRRS and Pseudorabies.
