answer is C
Explanation Episcleritis-an inflammatory condition of the episclera. Usually sectoral and self limiting. The eye is often tender and mildly photophobic. 2.5% neosynephrine topically can be used diagnostically:the conjuncival vessels blanch but the episcleral vessels remain engorged in episcleritis as opposed to conjunctivitis where most vessels blanch. Sectoral hyperemia, distinguished from conjunctivitis by radially oriented vessels that do not move with the conjunctiva. Episcleritis is self-limited, although topical non-steroidal anti-inflammatory medications such as flurbiprofen or diclofenac may hasten resolution. In contradistinction to scleritis, episcleritis is not usually related to systemic rheumatoid disease.
