Purpose:
To report four examples of a novel optical coherence tomography finding, which appears to be characteristic of inflammatory choroidal neovascularization.
Methods:
Retrospective observational case series.
Results:
Four eyes of four patients were diagnosed clinically with inflammatory choroidal neovascularization and underwent optical coherence tomography. In each case, imaging revealed multiple, distinctive finger-like projections extending from the area of active choroidal neovascularization into the outer retina-the "pitchfork sign"--a finding not typically seen in Type 2 neovascularization due to other etiologies.
Conclusion:
The pitchfork sign may help distinguish inflammatory choroidal neovascularization from other causes of Type 2 neovascularization.
