Journal Article

BACKGROUND AND OBJECTIVES:To image and measure iris tumors with optical coherence tomography (OCT). PATIENTS AND METHODS:High-speed (2,000-4,000 axial-scan/sec and 4-16 frames/sec) 1.3-micron wavelength anterior segment OCT prototypes were used to image 6 eyes of 6 patients with a variety of iris lesions, including focal iris nevus, diffuse iris nevus, amelanotic iris nevus, iris melanocytosis, and iris melanoma. OCT images were compared with slit-lamp photography and ultrasound biomicroscopy. RESULTS:OCT at 1.3-micron wavelength could penetrate the full thickness of the iris lesions and allow three-dimensional measurement of lesion size. Internal reflectivity is correlated with pigmentation. OCT is a convenient non-contact method that provides imaging of the clinically important angle structures (scleral spur and angle recess). CONCLUSIONS:OCT is a new imaging modality that complements slit-lamp photography and ultrasound biomicroscopy for serial evaluation of iris
