[Glaucoma with microcornea; morphometry and differential diagnosis].

To evaluate the characteristics of 10 glaucomatous cases with microcornea, we measured corneal diameter, curvature, axial length, and depth of anterior chamber, and examined the eyes with a specular microscope and an ultrasound biomicroscope. The ten cases examined in this study included 1 case of cornea plana, 2 cases of sclerocornea, 2 cases of nanophthalmos, and 5 cases of anterior microphthalmos. Three of the 10 cases were combined with open angle glaucoma, and the others with closed angle glaucoma. Open-angle glaucoma seemed like developmental glaucoma with angle maldevelopment. The closed angle type may appear at a younger age than in patients who have simple pupilary block. There are probably complex mechanisms related with closed angle glaucoma with microcornea. While differential diagnosis among these cases is relatively easy, we should evaluate how or why the intraocular pressure rises as far as possible before forming a treatment plan for each patient.
