What is the primary clinical presentation of Proliferative/Eosinophilic Keratitis?

The primary clinical presentation of Proliferative/Eosinophilic Keratitis is characterized by neovascularization and corneal plaque formation. This condition typically involves an inflammatory response in the cornea, leading to the growth of new blood vessels (neovascularization) as a response to the ongoing irritation and inflammation. The presence of corneal plaques forms as a result of the accumulation of eosinophils and other inflammatory cells, which can give the cornea a distinctive appearance.

Neovascularization indicates that there is a significant and persistent inflammatory process occurring in the cornea, often associated with conditions such as some forms of chronic keratitis or surface disease. The plaques and blood vessel growth are visual indicators that veterinarians can observe during ophthalmic examinations, allowing for a diagnosis of this specific keratitis type.

In contrast, decreased tear production typically presents in conditions like dry eye syndrome and is not the primary feature of Proliferative/Eosinophilic Keratitis. Lens opacification would be indicative of cataracts, which is unrelated to the keratitis process. Retinal detachment affects the retina and is a different issue from corneal diseases, emphasizing that the signs of neovascularization and plaque formation are the hallmark presentations of this keratitis type.
