ReviewRecent advances in neuro-imaging and the impact on neuro-ophthalmology.
Neuro-imaging is an essential part of the evaluation in patients with neuro-ophthalmologic disorders. Over the last two decades enormous advances in this area have been made allowing noninvasive evaluation of the orbit and brain. The idea of using nuclear magnetic resonance technology to produce images rather than the ionizing radiation of computed tomography (CT) began to emerge clinically in the late 1970s and early 1980s. ⋯ Recent advances in CT scanning (spiral and three-dimensional CT) and MRI (functional MRI and cine MRI) continue to affect significant changes in the discipline of neuro-ophthalmology. Furthermore, advances in MR angiography promise to allow excellent and noninvasive analysis of the cerebral vasculature. This review highlights the recent advances in neuro-imaging.

Diabetes and thyroid-related eye disease cause significant morbidity. Although these are endocrine disorders, they cause different ocular manifestations. Previously unexamined epidemiologic factors offer new insight to diabetic eye disease. ⋯ Thyroid-related eye disease, as seen in Graves' ophthalmopathy, is an autoimmune process. This is reexamined and new ultrasound techniques to measure disease activity are described. The advantage of therapies directed against these features is reported.
