Özet
Purpose: To evaluate choroidal thickness (CT) and choroidal vascularity index (CVI) in patients with primary Sjögren’s syndrome (pSS), and to compare these parameters with healthy controls. Methods: This study included 35 pSS patients and 37 healthy controls. CVI measurements were performed using enhanced depth imaging optical coherence tomography (EDI-OCT). The peripapillary nasal (PPN) and temporal (PPT) regions, with a width of 1000 µm, were analyzed, along with subfoveal (SF) areas at 500, 1000, and 1500 µm. The EDI-OCT images were transferred to ImageJ software for image binarization and CVI calculation. Subfoveal choroidal thickness (SFCT) was also measured. Results: There was no statistical difference in age, gender and BMI distribution between the groups (all p > 0.05). All CVI values at 5 different measurement points (SF 500 µm, SF 1000 µm, SF 1500 µm, PPN and PPT) were significantly lower in the pSS group (p = 0.01, p = 0.07, p = 0.017, p = 0.03 and p = 0.019, respectively). SFCT values were found to be significantly lower in the patient group (326.2 ± 89.4 µm vs 380.6 ± 78.2 µm, p = 0.008). A significant positive correlation was found between SFCT measurements and PPN CVI and PPT CVI values (r = 0.515, p = 0.002; r = 0.493, p = 0.003, respectively). Conclusion: We detected significantly thinned CT and decreased CVI values in patients with pSS, for the first time. As a result of our study, CT and CVI measurements may become parameters that can be used in the follow-up of pSS patients in whom no pathology is detected in routine eye examination and perhaps in the evaluation of treatment response.
