To describe the technology of optical coherence tomography (OCT) in imaging the anterior chamber angles and its impact on understanding the pathophysiology of angle-closure glaucoma (ACG). ⋯ The commercially available OCT unit can be practically employed for anterior chamber angle imaging. The different patterns of angle configurations are correlated with the underlying pathophysiology in different forms of ACG.
-
To evaluate the incidence and extent of visual recovery in patients with giant cell arteritis (GCA) treated with high doses of systemic corticosteroids. ⋯ Visual recovery is uncommon in patients who lose vision from GCA. Recovery in visual acuity is not associated with visual field or color vision improvement in this series. Visual deterioration occurs in approximately 27% of eyes despite high-dose IV methylprednisolone. The greatest risk of visual deterioration is in the first 6 days.
-
To investigate the manifestations and clinical course of Coats' disease diagnosed in adulthood and to describe the characteristics of patients who develop it. ⋯ Coats' disease can first be diagnosed in adulthood with retinal vascular abnormalities similar to those seen in younger patients. There are a number of important differences in disease manifestation in adults, including limited area of involvement, slower apparent progression of disease, and hemorrhage near larger vascular dilatations.

To design a model-system instruction course to prepare trainees for performing goniotomy on patients. ⋯ This model system instruction course can assist trainees in learning to perform goniotomy while potentially lessening the risks to patients.
