PURPOSE: The purpose of this report is to describe a case of lipemia retinalis due to decompensating hyperlipidemia that occurred during chemotherapy in a patient with metastatic colon carcinoma. METHODS: Retrospective case report. RESULTS: A 55-year-old non-insulin-dependent diabetic man with well-controlled hyperlipidemia presented himself with temporarily blurred vision in both eyes occurring during chemotherapy. He was found to have lipemia retinalis in his both eyes...

Reproduction is regulated by the hypothalamic-pituitary-gonadal axis. The first neuropeptide identified that regulates this function was the decapeptide gonadotropin-releasing hormone (GnRH). Nowadays, in gnatostomates, a number of GnRH variants have been identified and classified into three different types: GnRH1, GnRH2, and GnRH3. Almost 30 years later, a new peptide that inhibits gonadotropin synthesis and secretion was discovered and thus named as gonadotropin-inhibitory hormone (GnIH). In avians and mammals, the interaction and regulation between GnRH and GnIH neurons has been widely studied; however, in other vertebrate groups there is little information about the relationship between these neurons...

RFamide peptides are expressed in the early stages of development in most vertebrates. Gonadotropin-inhibitory hormone (GnIH) belongs to the RFamide family, and its role in reproduction has been widely studied in adult vertebrates, ranging from fish to mammals. As only three reports evaluated GnIH during development, the aim of this study was to characterise the ontogeny of GnIH in a fish model, Cichlasoma dimerus. We detected the presence of two GnIH-immunoreactive (GnIH-ir) cell clusters with spatial and temporal differences...

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...

Severe hypertriglyceridemia is the third most common cause of acute pancreatitis and is strongly associated with an increased risk of cardiovascular disease. In infants, the most common cause of severe hypertriglyceridemia is lipoprotein lipase deficiency. We describe a 7-week-old infant with severe hypertriglyceridemia, who presented with frequent gastrointestinal bleeding, respiratory distress, a decreased level of consciousness and lipemia retinalis. Triglycerides were reduced from 734 to 2 mmol/L (64,956-177 mg/dL), by exchange transfusions...

OBJECTIVE: To describe the characteristic retinal features of lipemia retinalis when using ultrawide field scanning laser ophthalmoscopy. MAIN POINTS: We report a case series of three subjects with ultrawide field retinal images showing cream discoloration of the fundus, light salmon-coloured posterior retinal vessels and greyish pink peripheral vasculature. On green-only imaging, many of the vessels appear light rather than typically dark. CONCLUSION: Lipemia retinalis is readily apparent on ultrawide field imaging and illustrates the alterations that systemic diseases may induce in the posterior and peripheral retinal vasculature...

Lipemia retinalis is an unusual ocular finding associated with hypertriglyceridemia. We report the case of an infant treated for retinopathy of prematurity who later developed lipemia retinalis, with triglyceride levels of 4736 mg/dl. There was a paradoxical worsening of hypertriglyceridemia with the use of medium chain triglyceride supplement. On discontinuing the supplement, the triglycerides level drastically dropped, and retinal vasculature returned to a normal hue.

Severe hypertriglyceridemia is defined at a plasma triglyceride (TG) concentration of >885 mg/dl and may result - in particular when clinical symptoms appear before the age of 40 - from "large variant" mutations in genes which influence the function of the lipoprotein lipase (LPL). For diagnosis, secondary factors have to be excluded and treated before further genetic tests are considered. Typical symptoms in almost all patients are recurrent, sometimes severe abdominal pain attacks, which can result in acute pancreatitis, the most important, sometimes life-threatening complication...

PURPOSE: To describe multicolor scanning laser imaging (MSLI) and conventional fundus photography findings in lipemia retinalis (LR). METHODS: We report two LR cases. The first case is a 47-year-old diabetic woman with LR secondary to familial hypertriglyceridemia examined with MSLI, conventional fundus photography, and optical coherence tomography (OCT). The second case is a 39-year-old diabetic man with hypertriglyceridemia and LR. He was followed over time with conventional fundus photography of his retina until metabolic control was achieved...

PURPOSE: To report a case of successful treatment for severe lipemia retinalis with extreme severe hypertriglyceridemia (sHTG). DESIGN: Observational case report. OBSERVATIONS: A 6-week-old infant with severe lipemia retinalis manifested diffuse creamy retinal vessels complicated with vulvar xanthomas. Extreme sHTG with 185-folds of the normal level was reported. Chromosome microarray and lipid gene sequencing confirmed a homozygous lipoprotein lipase gene coding mutation...

Lipemia retinalis is a rare and asymptomatic condition which occurs when high levels of triglycerides and chylomicrons are present in blood. We report a rare case of secondary hyperlipoproteinemia in a 27 year old type 1 diabetes patient who presented with diabetic ketoacidosis and this peculiar ocular manifestation. The fundoscopic abnormality and creamy white serum cleared as the level of chylomicrons in the plasma dropped with intensive insulin therapy.

Type I hyperlipoproteinemia (T1HLP) usually presents with extreme hypertriglyceridemia, recurrent episodes of acute pancreatitis, lipemia retinalis, and cutaneous eruptive xanthomas. We report a unique 10-year-old male of Indian origin who presented in neonatal period with transient obstructive jaundice and xanthomas in the pancreas and kidneys. Serum triglycerides stabilized with extremely low-fat diet although he subsequently developed pancreatic atrophy. Extreme hypertriglyceridemia failed to respond to treatment with fenofibrate, fish oil, and orlistat...

Severe hypertriglyceridemia can give rise to a fundus appearance with whitish-colored retinal vessels called lipemia retinalis. A 52-year-old man with hypertriglyceridemia presented with a best-corrected visual acuity of 20/20 in both eyes and creamy-white retinal vessels on fundus. Spectral-domain optical coherence tomography (SD-OCT) revealed hyperreflective and engorged retinal vessels and white dots mainly accumulated in the inner nuclear and ganglion cell layer. Follow-up fundus examination after plasmapheresis sessions revealed normal retinal vessels...

The role of gonadotrophin-inhibitory hormone (GnIH) in the inhibition of the reproductive axis has been well-established in birds and mammals. However, its role in other vertebrates, such as the teleost fish, remains controversial. In this context, the present study aimed to evaluate whether GnIH modulates the release of gonadotrophins and growth hormone (GH) in the cichlid fish Cichlasoma dimerus. First, we partially sequenced the precursor polypeptide for GnIH and identified three putative GnIH peptides. Next, we analysed the expression of this precursor polypeptide via a polymerase chain reaction in the reproductive axis of both sexes...

Moderately elevated plasma/serum triglycerides (2-10 mmol/l) signalize increased risk for cardiovascular disease or presence of non-alcoholic steatohepatitis. Extremely elevated triglycerides (more than 10 mmol/l) signalize increased risk for pancreatitis and lipemia retinalis. The concentration of triglycerides is regulated by many genetic and nongenetic factors. Extremely elevated triglycerides not provoked by nutritional factors, especially inappropriate alcohol intake are more likely to have a monogenic cause...

Lipoprotein lipase (LPL) deficiency is an autosomal recessive condition due to absent or decreased activity of LPL enzyme. The LPL deficiency is a rare condition that is mainly diagnosed in children, but there is no standard screening method at this time. In our report, we describe a 6-day-old male infant who was found to have hypertriglyceridemia after lipemia retinalis was diagnosed from a fundoscopic examination for nonaccidental trauma work-up. After dietary modification was done, his triglyceride levels decreased significantly, and there were no complications...
