Anterior migration of a posterior segment scleral band: A case report with review of literature

Scleral bands are an age-old surgical technique used for attaching the detached retina with a rhegmatogenous component. It has been associated with multiple ocular complications. However, anterior migration into the cornea is very rare. We report the unique case of a 17-year-old patient who presented with spontaneous intracorneal migration of the silicon band post-scleral buckling. We demonstrate the utility of anterior segment optical coherence tomography (AS-OCT) in such a scenario demonstrating the extent of the intrusion of the band into the intracorneal tissue. Migrated scleral bands usually need explantation if there is an extrusion or associated retinal detachment, or if the migration has led to an intraocular pressure change or any extraocular motility disturbance causing diplopia. We also narrate the other similar cases of anterior migration of the scleral band in detail.
