Anterior Segment Configuration

Arch Ophthalmol. 1982;100(1):164. doi:10.1001/archopht.1982.01030030166024

To the Editor.  —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
