ker·a·to·cyte (k r  -t -s t )n. A fibroblastic stromal cell of the cornea. |
keratocyte.
See corneal corpuscle.
Bite Cell
An erythrocyte formed when haemoglobin denatures—as occurs in alpha-thalassemia or G6PD deficiency—and precipitates—due to oxidation—into clumps (Heinz bodies) that stick to the red cell membrane; the spleen ‘pits out’ a fragment of membrane with precipitated haemoglobin as the cells pass through the sinusoids, hence the term ‘bite’
keratocyte
1. a flattened connective tissue cell lying between the fibrous tissue lamellae which constitute the cornea. The keratocyte has branching processes that communicate with those of other keratocytes.
2. a red blood cell with notches that results in projections that look like horns. Keratocytes occur when fibrin is being deposited within blood vessels as in disseminated intravascular coagulation.
corneal corpuscle
Main cellular element of the corneal stroma. It is a flattened, dendritic cell located between the lamellae with a large flattened nucleus and lengthy processes which may communicate with neighbouring cells. These cells have fibroplastic and phagocytic functions. Syn. corneal fibrocyte; fixed cell; keratocyte.
