All of the following are true about blood staining of the cornea except

BLUNT TRAUMA Cornea Blood staining of cornea: It may occur occasionally from the associated hyphaema and raised intraocular pressure. Cornea becomes reddish brown or greenish in colour and in later stages simulates dislocation of the clear lens into the anterior chamber. It clears very slowly from the periphery towards the centre, the whole process may take even more than two years. Ref:- A K KHURANA; pg num:-404
