Conjunctiva: edema, hemorrhage.
Morphologic diagnosis: 
Conjunctiva: Severe acute diffuse edema and hemorrhage
Clinical description: 
This image was taken 5 days post experimental inoculation with viscerotropic velogenic Newcastle disease virus. Externally, this chicken had periocular edema. Here, the conjunctiva has been exposed through an incision to reveal the severe subconjunctival hemorrhages associated with the external lesions. There are aggregates of lymphoid tissue present in the conjunctiva of the bird, making this region a target for NCD virus replication.
Pathologic description: 
The conjunctival mucosa is swollen, wet, and gelatinous and there is one large, poorly defined, irregularly shaped dark red area as well as several smaller red foci that extend onto the nictitating membrane.
