Plain-English summary
A group of dogs with corneal calcification (hardening of the cornea) showed various symptoms, including corneal ulcers and lesions. In some cases, the condition affected both eyes, while others had issues in just one eye, often following previous severe eye problems. The exact cause of this mineralization is unclear, but it may be linked to underlying health issues like Cushing's Syndrome. Treatment involved surgery to remove damaged tissue and repair the eye, which helped some dogs recover.

Abstract
The purpose of this paper is to describe a specific presentation of canine corneal calcification. Fourteen cases are described. In seven cases the corneal lesions were bilaterally symmetrical. In five cases the corneal lesion was unilateral. Two dogs were uniocular, the contralateral eye had been enucleated between 1 and 3 months previously by the referring veterinary surgeon following corneal ulceration and perforation. Of a total of 21 eyes with corneal calcification, 16 eyes had associated ulceration. The ulceration presented as follows: two eyes had descemetocoeles, four eyes had corneal perforations, eight eyes had stromal ulceration, and two eyes had superficial punctate ulceration. The cause of the corneal mineralization remains undetermined but underlying systemic disease, particularly hyperadrenocorticism (Cushing's Syndrome), is suspected as a possible contributing factor in some of these cases. Histopathology was carried out on three cases following a keratectomy and placement of a conjunctival pedicle flap into the ulcerated lesion.
