On fundus examination apart from the narrowed arterioles and white appearing venules, the macula was found obscured with a large neovascular frond and pre-retinal hemorrhage which appeared to be fed by a solitary and tortuous new vessel, apparently originating from one of the photocoagulation scars nearly 3DD nasal to the optic disc margin [Figure 1].
(a and b) Sequential early phase angiograms of left eye showing the appearance of fluorescein dye in the new vessel prior to filling the arterioles at disc, (c) Subsequent frame of angiogram in arterial phase reveals the origin of the vessel from a photocoagulation scar confirming a choriovitreal neovascularization secondary to laser photocoagulation

The new vessel filled early in the choroidal phase of the angiogram, before the dye appeared in the retinal arteries indicative of its choroidal origin [Figure 2].
