What are signs of scleritis?
In scleritis, there is redness of the blood vessels adjacent to the sclera. This redness can have a bluish or violet tinge. With repeated episodes or long-standing scleritis, the sclera can thin and the underlying brown choroid may become visible through the residual sclera.
Scleritis may be nodular with multiple round or oval elevated areas of the sclera. Scleritis may also be necrotizing, resulting in areas of thinning and softening of the normally fairly rigid sclera. Areas of absence of redness may be due to death (necrosis) of inflamed blood vessels.
Scleritis can be characterized as being located in the front or back of the eye (anterior or posterior), depending on the location of the disease upon examination.
Visual acuity can be decreased if there is secondary clouding of the cornea or of the lens of the eye. Intraocular pressure can be increased from congestion of the blood vessels involved in draining aqueous fluid from the eye. Intraocular pressure can also be decreased if the ciliary body, which lies deeper than the sclera, is secondarily involved by inflammation.
Disturbances of eye movement can be seen since the extraocular muscles can become irritated where they insert into the sclera. This can cause double vision.
