Purpose:
To describe a case of a pigment epithelial detachment (PED) that likely led to a branch retinal vein occlusion (BRVO).
Methods:
Color photography, fluorescein angiography, and three-dimensional spectral optical coherence tomography (3D-spectral OCT) were performed.
Results:
Fluorescein angiography identified a PED at the site of a BRVO, and 3D-spectral OCT illustrated compression and distortion of the overlying retina at the location of the venous obstruction.
Conclusion:
It is well known that retinal arterial disease can compress an underlying vein and lead to a BRVO. A theoretically possible, but previously unrecognized cause of a BRVO is compression of an overlying vein by an underlying PED. Our case reminds us to continue to explore local anatomical factors in addition to systemic factors in patients with venous occlusive disease.
