22 A number of papers, which demonstrate linkage of J-POAG pedigrees with 1q21-q31, commented that the drainage angles and/or trabecular meshwork appeared normal 1950
51 However, a Danish pedigree, linked to 1q21-q31, has been described, in which gonioscopy showed various signs of goniodysgenesis—for example, high insertion of the iris, a grey membrane overlying the trabecular meshwork, and an abnormally exposed greater arterial circle of Willis, but no evidence of iris hypoplasia 56. The authors suggested that the absence of goniodysgenesis in other reported families needs to be explained.…”
