Choroidal Changes at the Leakage Site in Acute Central Serous Chorioretinopathy

ABSTRACT

Purpose: To analyze the choroidal vasculature at leak site and at the center of macula in acute central serous chorioretinopathy (CSCR) and to evaluate their co-relation with eccentricity of leak site.

Methods: This retrospective study involved optical coherence tomography analysis of 27 eyes with acute CSCR. Relationship between macular thickness; large choroidal vessels diameter; baseline subfoveal and leakage point choroidal thickness, and eccentricity of leak point was evaluated.

Results: A larger choroidal vessel caliber/choroidal thickness ratio was found at the leak site than fovea in both active (p = 0.0001) and resolved (p = 0.003) CSCR. Ratio at leakage point decreased after resolution of SRF (p = 0.004). Choroidal thickness at subfovea (p = 0.004), leakage point (p = 0.02); and difference between central and leakage point choroidal thickness (r = 0.6, p = 0.009) were significantly associated with the eccentricity of leakage point.

Conclusion: Subfoveal and leak site choroidal profile could predict the eccentricity of leakage in CSCR.
