Figure 5.

An algorithm highlighting clues to the diagnosis of OcMMP (ocular features, systemic involvement, autoimmune disease associations), together with differential diagnoses for conjunctival scarring subdivided into ‘static or slowly progressive' or ‘progressive' aetiologies is shown. A putative model for early referral to tertiary care hospitals is also suggested. †, A subset develop autoantibody-positive progressive conjunctival scarring similar to MMP; IF, immunofluorescence; MMP, mucous membrane pemphigoid.
