Coexistence of torpedo maculopathy and retinoblastoma: Differentiation the lesions with hand-held optical coherence tomography

Torpedo maculopathy (TM) is a rare congenital defect of the retina pigment epithelium, which always localizes to the temporal fovea. It is most commonly unilateral and often occurs in patients without any relevant disease. Classic finding is a flat, hypopigmented, oval lesion, resembling a 'torpedo,' with a wedge-shaped tail extending outward and directed toward the foveola. Visual acuity is generally unaffected due to the central fovea is not involved and this lesions remain stable. Therefore, when it accompanied with a posterior segment disease, we should make differential diagnosis to avoid unnecessary treatment. Herein, we present a child with coexistence of TM and retinoblastoma, and how to manage the lesions. We aimed to alert the ophthalmologists to this unusual combination for avoiding unnecessary treatment modalities. To the best of our knowledge, this combination that has never before been described.
