Double retina sign: A new optical coherence tomography finding in combined hamartoma of the retina and retinal pigment epithelium

Purpose: To describe a case of combined hamartoma of the retina and retinal pigment epithelium (CHRRPE) with peculiar optical coherence tomography (OCT) findings.Methods: Case report.Results: A 7-year-old girl with a history of decreased visual acuity in the left eye since early childhood presented with pigmented epiretinal membrane in favor of CHRRPE based on clinical and paraclinical findings. In OCT images, an area of retinal defect was noted, and the retina doubled up on itself near the defect (double retina sign).Conclusion: Careful examination of OCT images in patients with CHRRPE can reveal new findings.
