(A) Fluorescein angiography of the OD showing patchy choroidal hyperfluorescence underlying the tumour, with a neovascular membrane at the medial edge of the osteoma. (B) Optical coherence tomography of the OD showing type 1 choroidal neovascular membrane (CNVM). Lattice-work reflectivity is seen corresponding to bone trabeculae (white arrow). (C) Swept-source optical coherence tomography angiograph showing high-resolution superficial network of dilated vessels (white arrowhead) corresponding at the level of CNVM. Tumour vessels in a Medusa head appearance with two visible connections, possibly feeders for CNVM, are also seen (white arrow). (D) Swept-source optical coherence tomography angiograph showing a deeper network of fine thin vessels at the level of the tumour (white arrow).
