opacity 

The condition of a tissue or structure which is not transparent, or being opaque. The location of an opacity within the eye can be determined with a slit-lamp. It can also be determined using an ophthalmoscope and asking the patient to look up or down. If the opacity moves very little, or not at all, it is situated in the lens. If the opacity moves in the same direction as the eye it is situated in front of the lens and if it moves in the opposite direction it is situated in the vitreous humour. See cataract; muscae volitantes; corneal ulcer.
