Abstract
PURPOSE Recent studies have questioned the traditional view, which regards Coats disease as a strictly unilateral entity. Applying optical coherence tomography angiography, this prospective, monocentric study investigates quantitative capillary changes of the macula associated with Coats disease. METHODS Twenty-four eyes (4 untreated, 8 pre-treated) of 12 patients with stage 2 Coats disease (age range: 9-61 years) and 15 eyes of healthy, age-matched controls from the University of Muenster Medical Center, Germany received macular optical coherence tomography angiography measurements of the superficial, deep, and choriocapillary capillary plexus. Flow density and parameters related to the foveal avascular zone were compared between Coats eyes and fellow eyes, and between fellow eyes and control eyes. Additional subanalyses investigated changes based on disease stage. RESULTS Flow density did not differ between fellow eyes of Coats disease patients and control eyes in any of the parameters investigated. Comparison of Coats eyes to their respective fellow eyes revealed Coats disease to be associated with lower flow density in superficial, deep, and choriocapillary capillary plexus regions, irrespective of disease stage (all P < 0.03). There were no noticeable differences regarding the size or symmetry of the foveal avascular zone. CONCLUSION In light of the recent discussion around the unilateral character of Coats disease, this trial provides evidence against a bilateral presentation of vascular changes in the macula.

Abstract
Background This study aimed at defining the variance of vessel density (VD) characteristics in the macula of children with normal eyes. Methods This was a cross-sectional study in which subjects with normal eyes aged 3–18 years were enrolled. The macula was scanned by optical coherence tomography angiography (OCTA). Four age groups as under 7 years, 7–10 years, 11–14 years and more than 14 years of age were defined. The influences of age, gender, and body mass index on VD were analyzed. Results A total of 108 normal eyes from 54 participants with a mean age of 10.9 years were enrolled in the study. At the superficial and deep retina capillary plexus (SCP and DCP) and choriocapillaris (CC), respectively, the mean VD of the fovea was 20.10%, 36.99%, and 75.67%; at parafovea, these measurements were 53.12%, 55.81%, and 69.76%; and at perifovea, these measures were 51.38%, 52.46%, and 73.47%. The median foveal avascular zone (FAZ) was 0.30 mm2. No significant differences between superior-hemi VD and inferior-hemi VD were found in the studied plexuses. The VD at parafovea and perifovea CC differed significantly between groups. There was no variation in VD of macular retina and CC between eyes or sex. FAZ areas were different between genders. Conclusions No difference between eyes and genders in the retina and CC VD of macular area was noted. FAZ area was larger in male. Even though this is not a longitudinal study, it may provide us with hints about macular vascular development during puberty and clinical implications of OCTA in children.
