Topography-guided identification of leakage point in central serous chorioretinopathy: a base for fluorescein angiography-free focal laser photocoagulation.

This study demonstrates that PEDs localised in the upper half of the neurosensory detachment area and associated with the PROS thinning area coincided with the leakage point in a significant number of patients with CSC. The patients with non-resolving CSC with a small single PED localising in the upper one-third to one-half of the neurosensory detachment area with an area of PROS thinning above this PED may undergo FA-free OCT-guided FLP treating whole PED.
