BACKGROUNDLipemia retinalis (LR) is a rare disease related to hypertriglyceridemia. However, the symptoms of hypertriglyceridemia are insidious and difficult to detect without blood tests. The fundus is the only site where blood vessels can be observed directly. Understanding the specific performance of LR in multimodal imaging fundus examinations can help diagnose more patients with abnormal hyperlipidemia. CASE SUMMARYA 29-year-old woman with type 2 diabetes presented to our clinic complaining of a six-day loss of visual acuity in the left eye. The fundus color images showed typical LR: Arteries and veins were the same pink-white color. Infrared images showed hyperinfrared reflections of the arteries and veins. Optical coherence tomography (OCT) showed numerous high point-like reflections in the retinal section, corresponding to different calibers of blood vessel sections. Medium reflections were seen in the big vessels of the choroid. Fundus fluorescein angiography (FFA) and optical coherence tomography angiography (OCTA) showed no significant changes. Laboratory examination found a total cholesterol level of 13.98 mmol/L, triglyceride 20.55 mmol/L, which confirmed the diagnosis of LR. After treatment to lower blood lipids and control blood glucose, the fundus imaging showed that the blood lipids in the patient had returned to normal. CONCLUSIONLR shows specific changes in fundus color photography, infrared photography, and OCT. FFA and OCTA were not sensitive to LR changes.
