Cornea of the right eye showing an extensive elevated vascularised pink mass covering two-thirds of the epithelium, almost completely obstructing vision. Photograph taken under the surgical microscope, at the beginning of the superficial keratectomy. Ventral to the pink mass, the border of the nictitating membrane is visible in white

On ophthalmic examination, the cat presented with an extensive elevated pink mass that covered two-thirds of the cornea of the right eye (OD) (Figure 1). An attempt was made to achieve a surgical-free margin, sparing as much corneal stroma as possible (Figures 1-3).
Image showing the surgical site at the end of superficial keratectomy. Under the surgical microscope, after exeresis of the lesion with a crescent blade disposable knife, the superficial stroma layers were carefully dissected to separate them from the middle ones. There was diffuse discrete bleeding coming from the corneal neovascularisation

An attempt was made to achieve a surgical-free margin, sparing as much corneal stroma as possible (Figures 1-3).
After the completion of the microsurgical procedure, the mass was totally excised and a superficial corneal ulcer was created. The cornea regained its transparency and vision in the eye was restored

An attempt was made to achieve a surgical-free margin, sparing as much corneal stroma as possible (Figures 1-3).
Photomicrograph of the mass corresponding to a squamous cell carcinoma. Neoplastic squamous cells show an infiltrative growth pattern, with moderate squamous differentiation. The surrounding desmoplastic stroma contains an abundant lymphocytic inflammatory infiltrate (haematoxylin and eosin, bar 100 microm)

During one follow-up evaluation, 6 months after surgery, an almost clear cornea was appreciated, with only one vessel left at 4 o'clock and a discrete scarring at 8 o'clock. Symblepharon of the dorsal bulbar conjunctiva to the third eyelid was present at 2 o'clock. There was no epiphora or ocular discomfort, and there was no recurrence of the neoplasm

Over the course of treatment, the cornea regained transparency and decreased its neovascularisation (Figure 5).
