Posterior staphylomas and scleral curvature in highly myopic children and adolescents investigated by ultra-widefield optical coherence tomography
Fig 3
WF-OCT images of highly myopic eyes with peripapillary staphyloma without a scleral inward protrusion.
(A) Fundus photograph of the left eye of an 11-year-old girl with an axial length of 27.1 mm showing peripapillary diffuse atrophy. (B) Horizontal WF-OCT image shows that the nasal choroid gradually thins toward the staphyloma edge (arrow) and gradually re-thickens toward the posterior pole (arrowheads). Inner scleral surface is posteriorly displaced in the area between the edge of the staphyloma (arrow) and nasal edge of the optic disc, compared to the curvature more nasal to the staphyloma edge. However, the scleral inward protrusion at staphyloma edge is not obvious. (C) Right fundus photograph of a 17-year-old young man with an axial length of 28.1 mm showing peripapillary diffuse chorioretinal atrophy (PDCA). (D) Horizontal WF-OCT image showing that the inner scleral surface is slightly displaced posteriorly nasal to the optic nerve. The choroid gradually thins toward the edge of the staphyloma (arrow) and re-thickens toward the posterior pole (yellow arrowheads). However, scleral inward protrusion at the staphyloma edge is not obvious. Choroidal thickening closer to the optic nerve appears to be similar to peripapillary intrachoroidal cavitation. In the area of the PDCA (blue arrowheads), the scleral curvature is also displaced posteriorly.
