PURPOSE To report a new spectral domain optical coherence tomography finding of retinal herniation in a patient with macular detachment accompanying peripapillary detachment in pathologic myopia. METHODS Retrospective case report. A 47-year-old male patient with pathologic myopia and peripapillary detachment, pitlike defect, and associated macular detachment. RESULTS Spectral domain optical coherence tomography scan showed intrachoroidal cavitation, discontinuity of retinal layers over the pitlike defect with herniation of retinal tissue through which communication between the choroidal cavity and subretinal space was seen. CONCLUSION We report for the first time retinal herniation through pitlike dehiscence in pathologic myopia with intrachoroidal cavitation, and describe its association with macular detachment.
