摘　　要：PURPOSE: To report the electrophysiologic findings in a patient with lipaemia retinalis. DESIGN: Observational case report. METHODS: An 11-year-old girl wit h diabetes had hyperlipidemia and presented for ophthalmologic consultation. Fun dus examinations revealed milky discoloration of retinal vessels in both eyes. L aboratory testing disclosed hyperglycemia and markedly elevated level of triglyc erides and cholesterol. Although the visual acuity was not affected, the electro retinograms showed decrease amplitudes of a-and b-wave in both cone and rod re sponses. RESULTS: After correction of blood sugar and lipids with insulin and di et control, the lipaemia retinalis resolved, and the impaired ERG response rever sed within 1 week. CONCLUSIONS: Lipaemia retinalis usually resolves rapidly with out visual impairment after correction of hyperlipidemia. The reversible deficit s of electroretinogram response in lipaemia retinalis are reported for the first time. High level of triglycerides or cholesterol or both may impair retinal fun ction. The mechanism of an impaired electroretinogram remained speculative.PURPOSE: To report the electrophysiologic findings in a patient with lipaemia retinalis. DESIGN: Observational case report.
