People with diabetes mellitus are prone to complications from plantar warts related to the development of sores or ulceration and the poor healing potential associated with diabetes.
It's certainly more tempting than kibble, and will give the digestive acids something to do besides irritate any ulceration that might be present.
If a corneal abrasion is not treated appropriately, scarring and ulceration of the corneal are possible.
When the trigeminus nerve is divided (Majendie), or when its root is compressed injuriously, say Iby a tubercular tumour, the cornea begins to show points of ulceration, which, increasing in area, may bring about total disintegration of the eyeball.
The subsequent experiments of Snellen, Senftleben, and, more lately, of Turner, seem to show that if the eyeball be protected from the impingement of foreign particles, an accident to which it is liable owing to its state of anaesthesia, the ulceration may be warded off indefinitely.
