BACKGROUND: Intraocular epithelial downgrowth is a rare but potentially devastating posttraumatic complication. If left untreated, this may result in corneal decompensation, secondary angle-closure glaucoma, retinal detachment and blindness. PATIENT AND METHOD: A 10-year-old patient with penetrating globe injury and delayed wound management elsewhere presented with corneal melting and decompensation, retinal detachment and ocular hypotony. Following penetrating keratoplasty, cyclopexy and vitrectomy, corneal melting in the interface with renewed retinal detachment was noted within days. The hopeless prognosis required enucleation of the globe. RESULTS: Optical coherence tomography revealed not only corneal melting, but also markedly hyperreflective structures posterior to the cornea. Immunohistology demonstrated diffuse multi-layered nonkeratinised squamous cell epithelium on the posterior corneal surface, iris, ciliary bodies, and retina, as well as below the choroid, with renewed tractional retinal detachment. CONCLUSION: Posttraumatic epithelial downgrowth may result in tractional retinal detachment, cyclodialysis cleft and/or corneal melting. Hyperreflective membrane deposits on OCT may be indicative of diffuse epithelial downgrowth. Especially in children, prompt wound closure in globe injuries is vital to avoid this serious posttraumatic complication.
