Fundus fluorescein angiography (FFA) in a patient with central serous chorioretinopathy (CSCR) most characteristically shows which pattern of leakage?
- A Lacy petaloid pattern at the macula
- B Disc leakage with late staining
- C Blocked fluorescence with window defect
- D Inkblot pattern of leakage ✓
Explanation
In CSCR, FFA shows one or two focal leakage points at the level of the RPE, classically displaying an 'inkblot' pattern where dye gradually expands outward from a central point, or a 'smokestack' pattern where dye rises vertically then spreads laterally. The lacy petaloid pattern is seen in cystoid macular oedema. Disc leakage occurs in papilloedema. Window defects arise from RPE atrophy, not leakage.
