What is rubeosis iridis indicative of?

Rubeosis iridis refers to a condition characterized by the abnormal formation of new blood vessels on the surface of the iris, which is known as neovascularization of the iris. This phenomenon often occurs in response to various underlying conditions, typically related to chronic intraocular inflammation or ischemia (insufficient blood supply). Conditions such as diabetes mellitus, retinal ischemia due to obstruction of blood vessels, or other diseases affecting the retina can lead to the release of growth factors that stimulate the formation of new blood vessels in the iris.

The presence of rubeosis iridis can be indicative of significant ocular pathology, and it is often associated with complications that can affect vision. Recognizing this condition is crucial in veterinary ophthalmology, as it may necessitate further investigation and management of the underlying causes to prevent complications like glaucoma or severe visual impairment.
