Age in angle-closure glaucoma and the normal - a study in profile photography.

The horizontal corneal diameters of normal subjects of differing age and of those with angle-closure glaucoma were measured by surface and profile photography in the absence of the influence of axial length. The correlationship found between age and corneal diameter of surface photography for normal subjects was not found in the case of measurement by the technique which was independent of opacification of the peripheral zones of the cornea i.e., profile photography. No relationship was found between age and corneal diameter by either technique for the angle-closure glaucoma subjects.
