In CSR management, the laser is directed at which source?

• A. PED source
• B. Fovea
• C. Retina nerve fiber layer
• D. Optic disc

Answer: (A)

In central serous retinopathy, the treatment goal with laser is to seal the source of leakage at the site where fluid escapes from the pigment epithelium. This leakage point is often associated with a pigment epithelium detachment, and directing focal laser photocoagulation to that exact source creates a small scar that helps seal the defect. As a result, the subretinal fluid stops accumulating and the retina reattaches. It’s important to target the leakage site rather than the fovea, because laser near the fovea risks damaging central vision, and the true leakage source in CSR is not the retinal nerve fiber layer or the optic disc.
