ABSTRACT
A man in his 60s presented for his medical retina clinic appointment, reporting increasing shortness of breath, aches and pains, and increasing insulin requirements during a difficult early lockdown. Wide-field colour fundus imaging (Optos Optomap) and an optical coherence tomography scan (Heidelberg Spectralis) revealed whitened and enlarged hyper-reflective vessels. Retinal colour photography also confirmed a creamy white discolouration of the vessels, which prompted the team to order a lipid profile. The profile showed a raised cholesterol level of 17.5 mmol/L (normal: <4mmol/L) and a marked elevated triglyceride level of 38.41 mmol/L (normal: <1.7 mmol/L).The clinical picture, alongside the biochemical results, suggested a diagnosis of secondary lipaemia retinalis due to poorly controlled diabetes. With aggressive treatment, the patient's biochemistry and vessels returned to baseline.This rare condition should be taken as an indicator of a potential underlying life-threatening medical condition and the role an ophthalmologist has in initiating potential lifesaving intervention.
