Canine, feline, and equine corneal vascular neoplasia: A retrospective study (2007-2015).

The study is about the analysis of rare corneal vascular neoplasms (hemangioma and hemangiosarcoma) in dogs, cats, and horses collected over the time from 2007 to 2015. They discuss the breed, age, and characteristics specific to the tumors, while also discussing potential links with ongoing eye surface diseases.

Objective of the Study

• The research was aimed at listing and analyzing recorded cases of two specific types of corneal vascular neoplasms namely, hemangioma and hemangiosarcoma, in dogs, cats, and horses.
• The researchers explored the characteristics, types, breeds and ages of the animals affected by these primarily corneal tumors.
• They also speculate on the possible connection of these tumors with chronic diseases affecting the ocular surface.

Methods of the Study

• The researchers obtained archived cases from Comparative Ocular Pathology Lab of Wisconsin (COPLOW) that spanned from 2007 to 2015 containing instances of corneal hemangioma and hemangiosarcoma in horses, cats, and dogs.
• The data was then organised and reviewed, focusing on the primary area of the corneal.
• Through thorough cover-to-cover case analysis, sizable information was gathered concerning the breeds, ages, tumor types as well as other attributes of the respective neoplasms.

Results and Discussion

• Gross and histologic images were used to describe the tumours appearing in the canine, feline and equine patients.
• Predisposing factors were also contemplated alongside investigating if these neoplasms have any association with chronic ocular surface diseases.
• These types of tumors were confirmed as rare, but the information gathered provides significant insights into the occurrence of corneal vascular neoplasms across these three species.
