Resumo PURPOSE: To describe high-speed (4000 axial scans/s) optical coherence tomography (OCT) findings in a patient with narrow angles.DESIGN: Interventional case report.METHODS: A 56-year-old woman was found to have occludable narrow angles on OCT screening. This was confirmed by gonioscopy. Bilateral iridotomy was performed. Imaging of the angles was performed with a high-speed OCT prototype before and after iridotomy.RESULTS: OCT showed narrow angle bilaterally. Cornea, sclera, scleral spur, trabecula, iris, and iris recess were visualized. After iridotomy, the OCT showed reduction of iris concavity and patent iridotomies. Quantitative measurements of trabecula,iris space area on the OCT images showed widening of the angles to nonoccludable values.CONCLUSIONS: A 1.3-mu m wavelength OCT allows non, contact quantitative assessment of the angle and may be useful in the management of narrow,angle glaucoma.
