Ultra-Wide Field OCT of Posterior Staphyloma

Ultra-wide field OCT (UWF-OCT) is a useful instrument for the detection and classification of posterior staphylomas. Morphological features of posterior staphylomas shown by UWF-OCT are gradual thinning of the choroid from the periphery toward the edge of the staphyloma and a gradual re-thickening of the choroid in the direction toward the posterior pole along with a posterior displacement of the sclera in the staphylomatous area. Also, there is a gradual thickening and inward protrusion of the sclera at the staphyloma edge. UWF-OCT will be a standard instrument for the detection of posterior staphylomas.
