Fundus photo, fluorescence angiography and optical coherent tomography of patient. (A). Ophthalmoscopic examination revealed an abnormal tangle of vessels and enlarged draining veins. (B). Fluorescence angiography revealed fluorescence leakage at a turn near the fovea. (C). Horizontally oriented optical coherence tomography revealed an increased macular thickness and an accumulation of intraretinal fluid, indicating macular oedema. (D). Six months after the third intravitreal injection of bevacizumab, ophthalmoscopic examination revealed a decreased calibre of the previously engorged draining veins and ghost vessels. (E). Fluorescence angiography revealed the absence of leakage at the fovea and a decreased calibre in the occluded arteries. (F). Horizontally oriented optical coherence tomography revealed a decreased macular thickness and the absence of an intraretinal cyst.
