Conjunctival connective tissue organization/scarring grading system for IVCM. Images are 400×400 μm. A, Normal: homogenous, amorphous appearance with occasional fine, wispy strand. B, Grade 1: Heterogeneous appearance with poorly defined clumps or bands present. C, Grade 2: clearly defined bands of tissue that constitute <50% of the area of the scan. D, Grade 3: clearly defined bands or sheets of tissue that constitute ≥50% of the area of the scan and in which striations are visible. If different grades of scarring are seen within a particular volume scan, then the highest grade is recorded. The connective tissue that is graded needs to be separate from that associated with the vascular tissue; if this is not possible then the scan is considered ungradable. IVCM = in vivo confocal microscopy.
