—I was interested in the article entitled "Anterior Segment Configuration Correlated With Shaffer's Grading of Anterior Chamber Angle" by Chan et al in the January Archives (1981;99:104-107).These authors have measured central and peripheral corneal thickness and central and peripheral anterior chamber depth using attachments 1 and 2, respectively, to the slitlamp (Haag-Streit).I have made similar measurements since 1969.1 In 1971, I advised to measure the peripheral anterior chamber depth for ascertaining the anterior chamber angle width independently from gonioscopic studies.2 In 1972, I published the values of the central and peripheral anterior chamber depth obtained from eyes with primary angle-closure glaucoma.3 In 1978, I measured the peripheral corneal thickness in eyes with primary angle-closure glaucoma and in eyes with primary open angle glaucoma.4
