As you know, the sclera is the white connective tissue covering that makes up most of the structures of the eye that you can see. On the front of the eye the sclera is covered with a transparent structure called the conjunctiva. Most of the time when the eye is injured (say while kickboxing) it is just this superficial structure, the conjunctiva) that is irritated or injured. Injury
or ulceration of the sclera underneath is much less common. Regardless, the first step would be to return to see an eye doctor
to have the problem formally diagnosed.
It is possible that your current eye irritation is unrelated to the prior problem, since irritation of the conjunctiva in particular is caused by all sorts of common allergies, weather conditions, etc. On the other hand, if your eye doctor determines that you do indeed have inflammation or ulceration of the sclera (scleritis) then that would require more intensive workup. I say this because many cases of scleritis are associated with an underlying systemic disease, such as rheumatoid arthritis
, and treating the scleritis also requires diagnosing and treating the underlying condition.
Call and set up a visit with your eye doctor at your earliest convenience.
