Conjunctival Diseases
0 Divided into palpebral and bulbar conjunctiva
Conjunctival Hyperemia
1. Superficial hyperemia is the dilation of the superficial vessels of the conjunctiva from the eyelids. The features of this type of hyperemia, which mostly occurs in conjunctival diseases, are light-colored, movement of dilated vessels with the conjunctiva, and fading with pressure.
2. Deep hyperemia
Deep hyperemia is the dilatation of the anterior ciliary vessels of the conjunctiva.
This type of hyperemia, which occurs mostly in cornea, uvea, sclera diseases and acute glaucoma crisis, is dark red in color, the vessels do not move together with the conjunctiva and do not fade with the pressure of hyperemia.
