Non-Responsive Diabetic Macular Edema and Spironolactone

Overview

Diabetic patients with macular edema and choroidal hyperpermeability (as manifested as a thick choroid on OCT (optical coherence tomography) and ICG hyperfluorescence on ICG) unresponsive to anti-VEGF (vascular endothelial growth factor) and steroid injections will be treated with spironolactone in addition to the continued treatment of anti-VEGF injections, specifically aflibercept (Eylea).

This is a non-randomized, prospective study of 10 patients referred during the years 2018 to 2020 with the diagnosis of Diabetic Macular Edema. Each patient was noted to have pachychoroid, choroidal hyperpermeability, and most important resistant to multiple anti-VEGF and steroid intravitreal injections, and have moderate vision loss. In addition, despite the fact that we use anti-VEGF medications, we do not know the levels of VEGF in the eye, nor do we have an explanation for the inability to respond to these drugs. This study will determine the degree of VEGF concentrations, response to anti-VEGF treatments, and determine biomarkers of inflammation as a means for explaining the cause of treatment resistance. Subsequently, another pathological process will be treated with spironolactone to see if the degree of contribution of choroidal hyperpermeability to the exudative process.
