Evaluation of Foveal Thickness and Macular Choroidal Thickness with Optical Coherence Tomography in Behcet's Disease

Objective: To evaluate the foveal thickness and macular choroidal thickness on patients who were diagnosed with Behcet's Disease (BD). Methods: A total of 60 patients were included in this prospective cross-sectional study. Patients were divided into two groups. Group 1 consisted of 30 patients who were diagnosed with BD and Group 2 consisted of 30 healthy controls. Detailed ophthalmological examination was performed on both groups and foveal thickness and macular choroidal thickness were measured with Spectral-Domain Optical Coherence Tomography (SD-OCT). To measure the choroidal thickness enhanced depth imaging OCT (EDI-OCT) technique was used. Results: Mean foveal thickness in BD patients was 216.06 +/- 53.14 mu m and mean subfoveal choroidal thickness was 363.21 +/- 85.22 mu m. Mean foveal thickness and subfoveal choroidal thickness in healthy controls was 211.65 +/- 16.60 mu m and 352.83 +/- 87.11 mu m respectively. There was no statistical significance between patients with BD and patients of the control group regarding foveal and subfoveal choroidal thickness. However, anatomical deformation of Ellipsoid Zone structure in OCT had the most effect on visual acuity (p=0.001). Conclusion: This study shows that there was no statistically significant difference in terms of foveal thickness and macular choroidal thickness in patients with BD.
