Quantitative Analysis Of Retinal Microcirculation İn Optical Coherence Tomography Angiography İn Cases With Behçet’s Disease Without Ocular İnvolvement. International Ophthalmology, 39,(10), 2213-2221.0165-57011573-2630https://dx.doi.org/10.1007/s10792-018-1059-zhttps://hdl.handle.net/20.500.12395/38143PurposeTo evaluate the retinal vascular plexus and choriocapillaris structures in patients with non-ocular Behcet's disease (BD) using optical coherence tomography angiography (OCTA).MethodsThe study included 42 eyes of non-ocular BD patients (study group) and 40 eyes of 20 healthy subjects (control group). Flow area (mm(2)), mean vascular density (VD) (%) and foveal avascular zone (FAZ) (mm(2)) were measured using OCTA (Optovue Inc., Fremont, CA, USA). Subfoveal choroidal thickness (CT) (mu m) and central macular thickness (CMT) (mu m) measurements were also performed.ResultsThe mean superficial capillary plexus, deep capillary plexus and choriocapillaris flow area values were found to be significantly lower in the study group than in the control group (p<0.001, p<0.001, p=0.008, respectively). In respect of mean VD, a statistically significant difference was determined between the study and control groups in both superficial and deep VD (p<0.001). No statistically significant difference was found out between the groups in respect of superficial FAZ, deep FAZ and CMT (p=0.165, p=0.477, p=0.457, respectively). The subfoveal CT was also measured to be significantly thicker in the study group than in the control group (p<0.001).ConclusionThe results obtained with OCTA revealed that there could be both retinal and choroidal involvement in non-ocular BD patients before the emergence of evident clinical findings.en10.1007/s10792-018-1059-zinfo:eu-repo/semantics/openAccessVascular densityFlow areaNon-flow areaNon-ocular Behcet's diseaseOptical coherence tomography angiography (OCTA)Article39102213222130875015Q2WOS:000491942400009Q4
