Foveal microanatomy documented by SD-OCT following treatment of advanced retinoblastoma

Progress in the treatment of retinoblastoma has greatly improved patient survival and globe salvage rates. The introduction of intraoperative spectral domain optical coherence tomography (OCT) allows visualization of foveal anatomy and microstructure to predict visual potential and facilitate planning for visual rehabilitation. Eyes with total retinal detachments secondary to exophytic retinoblastoma have OCT findings of absence or disruption of the external limiting membrane and ellipsoid layers. We document the evolution of foveal microanatomy reconstitution following the use of chemotherapy in a 1-year-old boy and illustrate the restoration of the external limiting membrane and ellipsoid layer, thus achieving normal foveal microanatomy.
