ANGIOGRAPHIC SMOKESTACK LEAKAGE NOT ASSOCIATED WITH CENTRAL SEROUS CHORIORETINOPATHY.

Purpose: To report a series of cases with smokestack leakage on fundus fluorescein angiography outside the clinical setting of central serous chorioretinopathy.

Methods: A multicenter, observational retrospective case series evaluating fundus fluorescein angiography on Topcon and Optos systems.

Results: Seven patients with neovascularization due to ischemic retinopathy demonstrated a unique smokestack pattern of angiographic leakage. The patients' ages ranged between 44 and 71 years and were seen at 3 academic teaching hospitals in the Washington-Baltimore metropolitan area. Five patients had been diagnosed with proliferative diabetic retinopathy, one with sickle cell ischemic retinopathy, and one with branch retinal artery occlusion; none of the patients had a known history or clinical signs of current or past central serous chorioretinopathy.

Conclusion: This is the first published case series to the author's knowledge of ischemic retinopathy displaying a smokestack leakage pattern on fundus fluorescein angiography that is classically described with idiopathic central serous chorioretinopathy.
