Exophthalmos refers to an enlarged orbital space or enlarged globe.
This condition can occur as a non-symptomatic hereditary trait in certain breeds such as the Pug and Pekingese due to conformational breeding traits, characterized by eyes proportionally larger than the face.
Diseases associated with exophthalmos include:
- Carnassial tooth root abscess
- Trauma and secondary proptosis
- Necrotizing scleritis
- Retrobulbar abscess
- Juvenile cranial hyperostosis
