Choroidal neovascularization as a trigger for central serous chorioretinopathy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTo investigate whether choroidal neovascularization (CNV) may occasionally precipitate central serous chorioretinopathy (CSCR) in patients with pachychoroid features, by analyzing cases where fluorescein angiography (FA)-confirmed leakage originated directly within the CNV lesion.
methodsIn this retrospective case series conducted at two tertiary referral centers, we reviewed patients with no prior history or signs of CSCR who presented with a first episode of CSCR and coexisting CNV between December 2024 and April 2025. Inclusion required at least one FA-confirmed leakage point located within the neovascular complex. Multimodal imaging—including FA, spectral-domain optical coherence tomography (SD-OCT), and optical coherence tomography angiography (OCTA)—was performed to detect CNV and evaluate its topographical relationship with leakage.
resultsAmong 202 patients screened, four met inclusion criteria (two males, two females; age range 54–58 years). All presented with a unilateral first episode of CSCR. In each case, FA and OCTA demonstrated precise colocalization of the leakage point within the CNV lesion. CNV was predominantly subfoveal and exhibited a mature morphology. Three patients were diagnosed simultaneously with CSCR and a neovascular membrane, while one developed CSCR during follow-up of a previously identified pachychoroid neovasculopathy. Subretinal fluid fluctuations were observed in all cases and often appeared independent of anti-VEGF treatment, suggesting a mechanism not exclusively driven by VEGF-mediated CNV activity.
conclusionsThis case series suggests that, within the pachychoroid spectrum, CNV may not only complicate chronic or complex CSCR but may also act as a direct trigger of acute episodes. These findings underscore the importance of multimodal imaging, particularly FA and OCTA, for comprehensive assessment of CSCR. Given the small sample size and retrospective design, these observations should be interpreted as hypothesis-generating and warrant confirmation in larger prospective studies.
