Study of MR imaging of optic nerve in the case with complication of disc anomaly and normal tension glaucoma
Nakao YNeuro-Ophthalmology Japan 2007; 24: 397-404
It is very difficult to diagnose an optic disc anomaly that has a glaucoma-like visual field impairment and cupping of the disc, whether or not it is complicated by glaucoma. However, even in the early stages of glaucoma, by using the short time inversion recovery (STIR) sequence of MRI, optic atrophy in the optic nerve is easily demonstratable as a high-signal intensity lesion. On the other hand, optic disc anomalies, such as myopic disc change with conus, optic hypoplasia, tilted disc, and disc coloboma, can be demonstrated as an iso-signal intensity on STIR images. Thus, when a high-signal intensity lesion is shown on a STIR image in the optic nerve with a disc anomaly, a diagnosis of complication of glaucoma can be made. Therefore, the STIR image of a MRI plays an important role in the diagnosis of glaucoma complications in cases with disc anomaly. LA: Japanese
