Figure 1
Preoperative fundus photography, fluorescein angiography, and optical coherence tomography. (A) Fundus photography of the left eye exhibiting severe intraretinal haemorrhage and macular oedema secondary to superotemporal secondary order branch retinal vein occlusion. Arrowhead denotes site of occlusion. The course of the vein is outlined by the white dots underneath and points towards 2 o’clock from the optic disc. (B) Fluorescein angiography of the left eye at 12 seconds exhibiting widespread blocked fluorescence secondary to haemorrhage, hyperfluorescence of the vessel wall, and extensive capillary dropout estimated at 10 disc diameters with vessel “pruning.” Arrowhead denotes site of occlusion. The course of the occluded vein is better outlined in this angiogram by the underlying white dots. (C) Fluorescein angiography of the left eye at 4 minutes exhibiting consistent capillary dropout, blocked fluorescence secondary to haemorrhage, and extensive leakage along capillary vessel walls. Arrowhead denotes site of occlusion. (D) Optical coherence tomography of the left eye exhibiting extensive macular oedema with large cystic spaces in the foveal region. Foveal thickness was calculated to be 512 µm.

Figure 2
Postoperative fundus photography, fluorescein angiography, and optical coherence tomography. (A) Fundus photography of the left eye exhibiting marked resolution of intraretinal haemorrhage and macular oedema, particularly in the foveal region. Arrowhead denotes site of previously complete occlusion. The course of the now ghost vessel is outlined by the white dots underneath. (B) Fluorescein angiography of the left eye at 10 seconds exhibiting noticeably decreased blocked fluorescence secondary to haemorrhage, continued hyperfluorescence of the vessel wall, and extensive but decreased capillary dropout estimated at approximately 5 disc diameters. Persistent, but less severe, vessel “pruning” was also evident. Arrowhead denotes site of previously complete occlusion. (C) Fluorescein angiography of the left eye at 6 minutes exhibiting decreased capillary dropout, persistent blocked fluorescence secondary to haemorrhage, and decreased leakage along capillary vessel walls. Decreased leakage is particularly noted in the foveal region. Arrowhead denotes site of occlusion. The course of the occluded vein is outlined in this angiogram by the underlying white dots. (D) Optical coherence tomography of the left eye exhibiting markedly decreased macular oedema and the absence of cystic spaces. Foveal thickness was calculated to be 133 µm.
