is benign recurrent inflammation of the episcleral tissue. The treatment you are having is by steroids
eye drops and it is correct.
Since you are having recurrent attacks of episcleritis I advice you to undergo investigations to rule out underlying systemic diseases or rarely connective tissue
diseases. Scleritis are known to be associated commonly with these diseases, however episcleritis are known to be associated with these diseases rarely.
Please do consult your eye doctor and ask him regarding the investigations like ESR, C Reactive protein
, RA factor and so many depending on the systemic history.
