One hundred persons have been subjected to slit‐lamp examination for scleral emissaries. The number registered per subject averaged 12.2. Such were most frequent superiorly at 12 o'clock and inferiorly at 6 o'clock, rarer nasally and the rarest temporally. The courses of the perforating blood vessels were equally often radial (30%), incyclo‐directed (28%), and excylo‐directed (29%), whereas rarely parallel with the limbus corneae (10%), and even more rarely irregularly winding (3%). Episcleral pigmentation in relation to emissaries was most frequently observed superiorly and where the vessels ran radial and limbus‐parallel courses, whereas rarely nasally and temporally and at excyclo‐directed and winding courses.
