Choroidal volume decreases with age. Choroidal perfusion is also decreased by 37% (Grunwald JE1998)- 50% (EDI-OCT study-Spaide RF 2009) in AMD. Vortex Veins Occlusion (VVO) might restore choriocapillaris perfusion. (Hayreh SS 1982, experiments in the Rhesus monkey, Bonnet M 1985, surgery in 17 human eyes with AMD). The goal of the study was to evaluate the choroidal perfusion after VVO.

Material and Methods:

Video cine ICG angiograms were performed (SD OCT HRA2) in 4 eyes of 4 patients, before and after VVO. 2 eyes had geographic atrophy, 1 eye presented confluent retrofoveal drusen and 1 eye had pseudo vitelliform dystrophy.

Results:

New venous drainage routes with visible pulsations were observed in all eyes. Dense vascular fillings were observed in previously hypoperfused areas. A “New drainage way” was demonstrated in all eyes

Conclusion:

VVO might enable partial reversibility of the rheological disturbances in AMD. VVO might be the only therapeutics currently available to delay the natural course of the disease in cases, in which vascular changes are the contributing factor.
