ABSTRACT
BACKGROUND:
To evaluate the changes in the peripapillary, macular and choriocapillaris microvasculatures in the eyes of patients with Behçet's disease (BD) without ocular involvement by optical coherence tomography angiography (OCT-A) and to investigate the relationship with systemic vascular involvement (SVI).METHODS:
The study included 56 eyes of 33 patients with non-ocular BD and 61 eyes of 33 healthy subjects. The macular microvascular (MMV) vessel densities (VDs), FAZ parameters, Choriocapillaris flow area (CCFA), radial peripapillary capillary (RPC) VDs and optic nerve head (ONH) analyses were performed with OCT-A. MMV, RPC, ONH, and CCFA measurements were compared between the non-ocular BD patients and healthy controls. Then, the patient group was divided into two subgroups according to the presence of SVI. MMV, RPC, and CCFA measurements of these subgroups were compared with the healthy controls.RESULTS:
While deep capillary plexus VD and foveal density decreased in MMV analysis in the BD group compared to the control group, CCFA was not different. In the RPC and ONH analysis, the VDs of the inside-disc small vessels and the VDs of the inside-disc all vessels were decreased while the cup/disk area ratio and cup volume were increased in the BD group compared to the healthy controls. Furthermore, the VDs of the inside-disc vessels were reduced in patients without SVI compared to those with SVI and healthy controls.CONCLUSIONS:
The RPC network, ONH and MMV architecture analysis by OCT-A revealed changes in the MMV, RPC, and ONH structures in non-ocular BD patients. Moreover, the decrease in RPC VDs and MMV VDs in patients without SVI suggested that the patients with BD without SVI had subclinical ocular involvement even in the absence of clinical ocular findings.Palabras clave
