Abstract

Purpose: The aim of this study was to describe dynamic color change in retinal vessels from white to coral pink due to externally applied ocular pressure in a 6-week-old infant with lipemia retinalis secondary to type 1b familial hyperlipoproteinemia. Methods: Fundus images and fluorescein angiogram were taken with RetCam3 camera. Color photographs of pooled blood were taken during phlebotomy. Results: Genetic analysis revealed a rare genetic mutation in the APOC2 gene, a lipoprotein lipase activator. Intraocular pressure applied to the globe induced a color change in the retinal arteries from white to coral pink. Disruption in laminar flow leading to this change is described. Conclusion: This is the first report to attribute the retinal vessel color change to disrupted laminar flow and the intermixing of larger erythrocytes and smaller chylomicrons in a patient with lipemia retinalis. In addition, this is a rare example of congenital hyperlipidemia in the offspring of nonconsanguineous parents.
