Red eye - hyperaemia
Red eye is a non-specific term used to describe an eye that appears red due to illness, injury, or other conditions. It can be common and occurs when blood vessels in the eye rupture and the white area of the eyeball (sclera) appears red. Veterinary advice should always be sought urgently when the rabbit's eyes appear red or different in any way. Some of the potential causes are less serious and occur commonly; others are rare but generally more serious.
