Ultra-widefield fundus photography for radiation therapy planning of ocular tumours.
Fundus photography of the same eye with choroidal melanoma using standard-field (SF) and ultra-widefield (UWF) imaging. SF (A–C) and UWF (D–F) were used to evaluate the differences in distances measured between 2 lengths. The optic disc was assumed to equal 1.5 mm in both techniques (A, D). The distance between a blood vessel branch near the tumour and the point it crossed the optic disc border were measured (B, E). A second measure ≥90° from the latter was also made (C, F).
