During fluorescein angiography of a patient with central serous chorioretinopathy (CSCR), the characteristic leakage pattern most often seen is:

• A Lacy perifoveal leakage in early phase expanding uniformly
• B Disc margin leakage with late staining
• C Window defect with no late leakage
• D Ink-blot or smokestack pattern of leakage at the level of RPE ✓

Explanation

CSCR shows a focal RPE leak on FFA that may appear as an expanding ink-blot (most common) or as an ascending smokestack pattern due to convection currents in the subretinal fluid. The leak originates at a pinpoint RPE defect and expands or ascends into the subretinal space. Window defects occur in RPE atrophy with no late leakage, and disc margin leakage is typical of papilledema.
