• The anterior chamber depths, volumes, and diameters were studied photogrammetrically in 273 patients with the clinical diagnosis of narrow angles (dome and plateau iris configuration) and acute, subacute, or chronic angle-closure glaucoma. The anterior chamber depths, volumes, and diameters of all of these patients were significantly smaller than age-, sex-, and refractive error-matched normal controls. Peripheral iridectomy significantly increased the peripheral depth of the anterior chamber and increased the volume of the anterior chamber by 14 μL without changing the central depth.
