Pterygium was group with stromal findings because it is possible for pterygium to extend into this layer. Therefore, the imaging requirements for pterygium is similar to other stromal findings.

Although OCT images are included for guttae, they may not always review the presence of guttae and should not be used as a substitution for any of the other two modalities.
