Fundus Florescence Angiography was done to identify margins of foveal avascular zone
, to rule out macular ischemia and determine the boundaries for macular grid laser application.
These include right-angle veins, subretinal and outer retinal neovascularization, and vascular invasion of the foveal avascular zone
Natural course of choroidal neovascular membranes within the foveal avascular zone
in senile macular degeneration.
24) In addition to the presence of an enlarged foveal avascular zone
is the macular depression sign; this represents atrophy and thinning of the inner retinal layers which can be seen with optical coherence tomography (OCT) and may be associated with a reduction in vision (see Figure 3).
Foveal cystoid spaces are associated with enlarged foveal avascular zone
and microaneurysms in diabetic macular edema.
