*6.2.6. Clinical activity of ophthalmopathy*

To know the clinical activity of ophthalmopathy is important, because active disease is more likely to respond to immunosuppressive therapy. Clinical Activity Score (CAS) is used to know the clinical activity. Seven parameters are used in the clinical activity scoring which include spontaneous retrobulbar pain, pain on eye movement, eyelid erythema, conjuctival injection, swelling of the eyelids, inflammation of the caruncle and conjunctival edema or chemosis. Each parameter is assigned 1 point. CAS of more than or equal to 3/7 indicates active ophthalmopathy.
