  Purpose: To report on the reliability of optical coherence tomography angiography (OCTA) to diagnose fovea plana. Methods: A retrospective, cross-sectional, case-control study included patients with foveal persistence of the inner retinal layers, confirmed by spectral domain OCT (SD-OCT), and superficial (SCP) and deep capillary plexus (DCP) foveal vascularization confirmed by OCTA. A healthy control group was selected. Best-corrected visual acuity (BCVA) was obtained. SD-OCT was used for measuring the outer nuclear layer thickness and OCTA determined the foveal avascular zone (FAZ), SCP and DCP vascular density (VD). Results: OCTA reliability, based on all parameters, reached 97%, while based only on ...

  Enhanced S-cone syndrome (ESCS) is an autosomal recessive retinal dystrophy associated with a NR2E3 mutation, causing night blindness, decreased visual acuity, and visual field defects [ 1 ]. Clinically, ESCS is characterized by annular pigmentation along the vascular arcades and macular abnormalities [ 2 ]. Best vitelliform macular dystrophy (BVMD) is also an autosomal but dominant hereditary retinal dystrophy associated with the BEST1 gene, which affects central vision with a relatively good prognosis and presents macular egg yolk yellow lesions [ 3 ]. A common characteristic of retinal dystrophies including ESCS and BVMD is the cystic macular lesions that appear in the retina and cause visual ...

  Purpose: This study aims at describing the macular vascular features of the eyes of pediatric patients with the homozygous form of sickle cell disease (SCD) using optical coherence tomography angiography . Methods: This is a retrospective case series of eyes of pediatric patients with SCD, race- and age-matched to those of healthy individuals. Using optical coherence tomography angiography images of superficial capillary plexus and deep capillary plexus, the nonflow area, vascular density, and foveal avascular zone were measured. The remodeled microvascular foveal architectures obtained on optical coherence tomography angiography and fluorescein angiography were compared. Results: A total of 19 eyes of ...

4. Macular telangiectasia type 1: capillary density and microvascular abnormalities assessed by optical coherence tomography angiography
  
  Explore American Journal of Ophthalmology Apr 13 2016 Ophthalmology
  
  Purpose To describe microvascular abnormalities and capillary density in macular telangiectasia type 1 (MT1) using optical coherence tomography angiography (OCTA), and correlate them with fluorescein angiography (FA). Design; Observational case series. Methods Seven patients with MT1 and 12 age-matched controls were included. Focal microvascular dilations were identified on 3×3-mm OCTA and early-frame FA images. OCTA images were processed to determine the global capillary density after subtraction of larger vessels and cystoid edema cavities. Local capillary densities were calculated inside 100-μm circles around telangiectasias, projected over superficial (SCP) and deep capillary plexuses (DCP). They were compared to a random ...
