Purpose:
To describe optical coherence tomography (OCT) characteristics of central serous chorioretinopathy (CSCR) without any hyperfluorescent leakage on fundus fluorescein angiography (FFA).
Methods:
This was a multicentric, retrospective, observational study of ten eyes of ten patients with CSCR without any hyperfluorescence leakage on FFA. Baseline patient characteristics, best corrected visual acuity, and OCT parameters like relative retinal pigment epithelium (RPE) reflectivity at the presumed leak site and control site were measured.
Results:
Increased macular thickness, neurosensory detachment, and choroidal thickness were seen at the site of maximum subretinal fluid (SRF). Out of ten eyes, nine had photoreceptor outer segment (PROS) disruption (46% ± 26.33%) at the site of SRF pocket, and five had presumed former leak site characterized by PROS thinning. The presumed leak site demonstrated higher RPE reflectivity compared to the control site (0.92 ± 0.04 vs. 0.87 ± 0.04; P = 0.0058).
Conclusion:
CSCR without hyperfluorescent leakage on FFA may have PROS damage and changes in RPE hyperreflectivity.
