To report a case of clinically invisible retinoblastoma recurrence detected only on spectral-domain optical coherence tomography.
A 3-week-old girl with bilateral familial retinoblastoma underwent six cycles of intravenous chemoreduction. Both eyes showed tumor regression. After 6 cycles of chemoreduction, the tumor in the right eye appeared with clinical regression; however, by spectral-domain optical coherence tomography, there was 40 μm increase in thickness and 290 μm increase in basal diameter. Due to tumor proximity of 1.85 mm to the foveola, the recurrence was treated via intraarterial chemotherapy with two cycles of Melphalan 3 mg. After treatment, spectral-domain optical coherence tomography showed complete regression of the recurrent tumor to a flat scar with intact fovea.
Precise submillimeter imaging with spectral-domain optical coherence tomography for monitoring retinoblastoma is important and can allow detection of early recurrences that might be clinically invisible otherwise, as well as surveillance of the fovea.
Clinically invisible submillimeter retinoblastoma recurrence in an infant was detected on spectral-domain optical coherence tomography and documentation of tumor regression after intraarterial chemotherapy was confirmed.
