Figure 3. AS-OCT and UBM for imaging stromal corneal dystrophy.

Figure 3

I: Many spots of hyper-reflection in the cornea were shown in the left eye of a 47-year-old woman with granular corneal dystrophy using AS-OCT (yellow arrows, a), while just diffuse hyper-reflection of the same intensity was shown using UBM (A).

II: Cloudy hyper-reflection with lines was noted in the left eye of a 47-year-old woman with lattice corneal dystrophy by AS-OCT, but no clear distance to the posterior boundary was noted (b). However, a dark narrow band between the diffuse hyper-reflection and the posterior corneal boundary was observed in the UBM images (red arrow, B).

III: For a 69-year-old woman with advanced-stage macular corneal dystrophy, both the AS-OCT image (c) and UBM image (C) showed diffuse signal hyper-reflection in the stroma without a clear distance to the posterior boundary in her right eye. However, the OCT image showed an uneven anterior surface of the cornea (yellow arrow, c).
