| Disease activity may be evaluated by recording changes over time in the objective measurements described above. Disease activity at one time may be assessed by assigning 1 point for the presence of each of the following signs and symptoms: spontaneous retrobulbar pain, pain on eye movements, eyelid erythema, conjunctival injection, chemosis, swelling of the caruncle, and eyelid edema or fullness. The sum of these points defines the clinical activity score (range 0-7) (Mourits et al. 1989). |
