Asymmetric choroidal vascular pattern in tilted disc syndrome.

Purpose: To observe the choroidal vasculature in patients with tilted disc syndrome (TDS) using en face optical coherence tomography (OCT) and to evaluate the symmetry of the choroidal vascular pattern in the macular area.

Methods: En face OCT was performed using a Plex Elite 9000 (Zeiss) with a 12 × 12 mm image of the macula, which was flattened with retinal pigment epithelium and segmented into choroidal layers. The middle/large choroidal vessels were evaluated for vertical symmetry qualitatively by the retina specialist coauthors and quantitatively by binarization analysis of choroidal vessel density and mean vessel diameter.

Foveal abnormalities determined by optical coherence tomography angiography in children with history of retinopathy of prematurity.

Purpose: To describe the foveal characteristics of children with a history of retinopathy of prematurity (ROP) using optical coherence tomography angiography (OCTA).

Methods: All eyes were examined by OCTA (RTVue AVANTI, Optovue Inc, Fremont, CA) with a scan of 3 × 3 mm cantered on the fovea. The size of the foveal avascular zone (FAZ), central retinal thickness (CRT), and foveal bulge were measured.
