Echographic evaluation of primary cysts of the iris pigment epithelium.

摘要: Purpose Primary cysts of the iris pigment epithelium frequently appear to be focal elevations peripheral iris. To differentiate them from other anterior segment tumors requires ability assess distribution, tissue characteristics, and progression such lesions, which we accomplished by using echography. Methods We reviewed medical records 49 consecutive patients referred Doheny Eye Institute for echographic evaluation bulging Echography was performed on each patient an immersion technique. Clinical examination also 20 (41%) at time initial examination. Results identified 52 epithelial in eyes studied. All lesions were single, localized posterior surface, demonstrated a well-circumscribed, echolucent structure B-scan Average maximal sagittal thickness 1.6 ± 0.4 mm. Cysts most located inferotemporal quadrant (31%). Minimal increase size or regression noted nine (ten eyes) whom follow-up examinations available. Conclusions possess characteristic features with regard location, size, internal structure, can accurately documented Clinically evident tend between 1 4 mm maximum thickness, conform contour chamber structures without distortion, produce iris, are preferentially quadrant, demonstrate limited potential growth.
