Purpose:
To describe the clinical course of a patient with persistent subretinal fluid (SRF) after primary scleral buckle surgery for a rhegmatogenous retinal detachment (RRD) repair who was subsequently treated with oral eplerenone for resolution of SRF.
Observations:
A 34 year-old-male presented with a large bullous macula-involving RRD of unknown duration and underwent primary scleral buckle and retinotomy for drainage of subretinal fluid (SRF). His post-operative course was characterized by persistent macular SRF for 1.5 years with poor vision largely unchanged from his pre-operative presentation. Patient declined additional surgical treatment and opted for conservative management. Given such persistent SRF, the patient was trialed on a course of oral eplerenone 50 mg po bid. After only one month on this therapy, a marked decline in SRF was noted with near complete resolution after two months.
Conclusions And Importance:
To our knowledge, this is the first report of its kind to show the effectivity of oral eplerenone treatment in the reduction of SRF following retinal detachment surgery.

Fluid Pressure
According to Pascal's law, a fluid at rest will generate equal pressure in all directions. This pressure is measured as a force per unit area, and its magnitude depends on the fluid's specific...
Accelerating Fluids
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:

CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....
