Ulcers of the cornea may generally be seen as little white spots near its margin. There is generally great sensitiveness to light, and severe pain, with congestion of the eye. This is a very serious affection, as penetration of the eye is quite apt to occur. The majority of cases are best treated by means of careful restriction of the diet, perfect rest of the eye in a darkened room, the application of a light bandage over the eye, and the use of the hot fomentation or hot spray three or four times a day half an hour each time. Ulcers of the cornea are very apt to leave behind them white spots.
