Hyperemia/redness of the eye

Ciliary flush, pericorneal hyperemia
Redness around the corneal limbus, typical finding in iritis, iridocyclitis (anterior uveitis) and keratitis

Combined hyperemia
Combination of conjunctival and ciliary flush / pericorneal hyperemia

Congestive hyperemia
Congestive, dark-red, dilated tortuous vessels on the eye bulb.
Occurs in acute angle-closure glaucoma together with cloudy cornea and often intense pain

Conjunctival hyperemia
Redness of the eye, most marked in the peripheral parts on the eye bulb and the inside of the eyelids, caused by dilation of small vessel and capillaries. The dilated vessels are movable above the sclera. Predominant sign in conjunctivitis

Episclera hyperemia
Usually unilateral, local, wedge-shaped injection on the sclera, more often localized temporally.
The area is characteristically pink-red and tender to touch . Typical sign of episcleritis

Local bleeding/Subconjunctival hemmorrhage
Spontaneous bleeding under the conjunctiva, can be compared to a bruise in the skin.
Appears as a blood-red patch or larger bleeding under the conjunctiva, with a sharp border to the surrounding, unaffected part of the eye

Lattice of small vessels growing from the periphery inwards on the upper part of the cornea.
Common sign in trachoma but occurs also as a reaction to contact lens wear. Can be seen occasionally as a result of a intense allergic reaction.
No specific treatment, but the use of contact lenses may have to be discontinued

Scleral hyperemia
Diffuse dark red area in a part of the sclera, very tender when touched. Characteristic finding, diagnostic for scleritis
