    1. Evaluation of different Swept’Source optical coherence tomography angiography (SS‐OCTA) slabs for the detection of features of diabetic retinopathy

      Evaluation of different Swept’Source optical coherence tomography angiography (SS‐OCTA) slabs for the detection of features of diabetic retinopathy

      Purpose To compare different Swept‐Source optical coherence tomography angiography (SS‐OCTA) slabs for the detection of features of diabetic retinopathy (DR), to find the most suitable slab for grading. Methods Retrospective cross‐sectional study. Consecutive patients with DR were evaluated using SS‐OCTA. The central 12 × 12 mm scan was used to generate the retinal, superficial and deep slab. The grading results of the slabs were then compared to determine if one specific slab is superior to detect respective features. Results A total of 348 eyes (190 patients; mean age 58.1 ± 14.5 years) were graded for features ...

    2. Repeatability of Wide-field Optical Coherence Tomography Angiography in Normal Retina

      Repeatability of Wide-field Optical Coherence Tomography Angiography in Normal Retina

      Purpose : We evaluated the repeatability of wide-field en face swept-source optical coherence tomography angiography (SS-OCTA) in healthy subjects. Methods : Healthy subjects underwent two imaging sessions, on average 8 days apart, with a 100 kHz SS-OCTA instrument. The imaging protocol included a central 3 × 3 and 12 × 12 mm scans of the four quadrants resulting in more than a 70° wide-field OCTA of the posterior pole. Quantitative analysis was performed using the inbuilt Macular Density Algorithm Version v0.6.1 and AngioTool software. Consistency for the foveal avascular zone (FAZ), vessel density, and perfusion density of the superficial and deep capillary ...

    3. Swept‐source optical coherence tomography angiography reveals vascular changes in intermediate uveitis

      Swept‐source optical coherence tomography angiography reveals vascular changes in intermediate uveitis

      Purpose To evaluate retinal and choroidal vascular changes in patients with intermediate uveitis with/without concomitant retinal vasculitis using wide field swept‐source optical coherence tomography angiography (OCTA). Methods In this study consecutive patients with intermediate uveitis ± vasculitis and healthy age‐matched controls were evaluated using central 3 × 3 mm OCTA scans and montage scans. Differences among the groups as well as the association between central changes assessed by 3 × 3 scans and wide field OCTA were evaluated. Results 93 eyes of 58 patients with intermediate uveitis and 33 healthy age‐matched controls were included. The presence of a cystoid ...

    4. Evaluation of vascular changes in intermediate uveitis and retinal vasculitis using swept-source wide-field optical coherence tomography angiography

      Evaluation of vascular changes in intermediate uveitis and retinal vasculitis using swept-source wide-field optical coherence tomography angiography

      Purpose To evaluate vascular changes in patients with intermediate uveitis with or without retinal vasculitis using swept-source wide-field optical coherence tomography angiography (OCTA). Methods This is a prospective cross-sectional study. Consecutive patients with intermediate uveitis were evaluated using wide-field OCTA. Wide-field OCTA and en-face OCT images were analysed for the presence of capillary non-perfusion and reduced perfusion, disruption of ellipsoid zone, and abnormalities on en-face wide-field retinal thickness maps, respectively, and compared with fluorescein angiography (FA) findings in a subcohort. Results 164 eyes of 88 patients with intermediate uveitis were included. Areas of capillary non-perfusion and reduced perfusion were more ...
