RESUMO
BACKGROUND: To evaluate choroidal vascularity index (CVI) and to investigate the association of CVI with neutrophil-to-lymphocyte ratio (NLR) as an indicator of inï¬ammation in obsessive-compulsive disorder (OCD). MATERIAL AND METHODS: This prospective study included newly diagnosed OCD patients and healthy controls. All patients underwent EDI-OCT imaging to assess the subfoveal choroidal thickness (sCT) and peripapillary CT (pCT). CVI was defined as the ratio of luminal area to stromal area after binarization on EDI-OCT images. RESULTS: A total of 39 patients with OCD and 25 controls were included. The sCT, pCT, and CVI values were significantly higher in the OCD vs. control group (pË0.05 for all). The NLR values were significantly higher in the OCD vs. control group (p = .007). A significant positive correlation was noted between CVI and NLR (p = .039). CONCLUSION: Our findings suggest that systemic inï¬ammation may play a role in the pathogenesis of OCD.

BACKGROUND: The aim of this study was to evaluate potential changes in choroidal flow in patients with newly diagnosed obsessive-compulsive disorder based on optical coherence tomography angiography findings and to investigate the relationship between subfoveal choroidal thickness and choriocapillaris flow area. METHODS: This prospective study included newly diagnosed obsessive-compulsive disorder patients and healthy controls. All patients underwent enhanced depth imaging-optical coherence tomography imaging to assess the subfoveal choroidal thickness and optical coherence tomography angiography imaging to evaluate the choriocapillaris flow area. RESULTS: A total of 55 patients with obsessive-compulsive disorder and 50 controls were included. The mean subfoveal choroidal thickness was significantly greater in the obsessive-compulsive disorder group compared to the control group (pË0.001). Regarding the choriocapillaris flow area, the values for area with a radius of 1 mm, 2 mm and 3 mm were significantly lower in the obsessive-compulsive disorder group than in the control group (p=0.019, p=0.014, and p=0.004, respectively). There was a significant negative correlation between subfoveal choroidal thickness and choriocapillaris flow area with a radius of 1mm (r=-0.387, p=0.024). CONCLUSION: Choroidal changes in obsessive-compulsive disorder patients suggest the choroidal features of uncomplicated pachychoroid. Obsessive-compulsive disorder may be prone to a spectrum of conditions characterized by pachychoroid features.
