Asymptomatic Leukemic Optic Nerve Infiltration as Presentation of Acute Lymphoblastic Leukemia Relapse.

The authors report a case of asymptomatic leukemic optic neuropathy as the first sign of acute lymphoblastic leukemia relapse in a 4-year-old boy. Routine ophthalmologic examination showed normal visual acuity and pupillary function in the presence of a tumoral mass covering the left optic disc. The mass resolved with preservation of vision after intrathecal chemotherapy. A routine ophthalmological examination is recommended for all patients with a history of acute lymphoblastic leukemia to exclude optic nerve involvement without systemic symptoms or signs. Vision can be preserved and radiation avoided by using targeted chemotherapy. [J Pediatr Ophthalmol Strabismus. 2017;54:e60-e62.].
