Purpose: Investigation of subfoveal choroidal thickness in Behçet disease (BD) with enhanced depth imaging optical coherence tomography (EDI-OCT).
Methods: The study included 35 patients with posterior uveitis (PU) associated with BD, 35 patients with BD without ocular involvement, and 30 healthy controls.
Results: There were no significant differences between the groups in terms of age, gender, axial length, or spherical equivalent refractive error. The mean subfoveal choroidal thickness was thinner in eyes with PU than in eyes without PU and healthy controls (p = 0.026).
Conclusion: EDI-OCT is a beneficial test for evaluating choroid morphology in BD. Thinning of the subfoveal choroidal tissue has been observed in patients with BD-associated PU.
