Fig. 1From: Parafoveolar retinoblastoma regression with foveal preservation following intra-arterial chemotherapy documented on hand-held optical coherence tomography in a newbornDocumentation of retinoblastoma control using spectral domain hand-held optical coherence tomography (HH-OCT). Following 6 cycles of intravenous chemotherapy for bilateral retinoblastoma, the left eye demonstrated small dome-shaped, outer retinal tumor recurrence (a) of 2750 µm in basal dimension and 792 µm thickness in the parafoveolar region, documented on HH-OCT (b) and with adjacent shallow subretinal fluid. The mass was 615 µm from the foveola. Following 1 cycle of intraarterial chemotherapy, the tumor showed complete regression (c) and HH-OCT (d) documented a concave scar of 120 µm in thickness and located 663 µm from foveola. There was OCT light transmission through atrophic retinal pigment epithelial accentuating the underlying thin choroid. The foveola remained intactBack to article page
