1. contraction of a blood clot. When first formed, a blood clot is a loose meshwork of fibres containing various blood cells. Over a period of time this contracts, producing a firm mass that seals the damaged blood vessels.
2. (in ophthalmology) degenerative shrinkage of the vitreous humour due to ageing, which usually results in a vitreous detachment.
