We evaluated the lens opacities in 6 eyes of 3 patients with myotonic dystrophy and in 2 eyes of a patient with suspected diagnosis. We used a slitlamp biomicroscope and an anterior segment analysis system. The characteristic granular opacities were located in the anterior cortical layer to the outer layer of the adult nucleus and were distributed in the equatorial and pupillary areas. Images by anterior segment analysis system allowed identification of increased light scatter in the subcapsular cortical layer which was difficult to detect by slitlamp observations. Lens images photographed by retroillumination showed the opacity in the posterior cortex to be wedge-shaped. The observed lens opacities were different in eyes with definite myotonic dystrophy from suspected ones. The findings show the usefulness of anterior segment analysis system in the diagnosis of lens opacities in myotonic dystrophy.
