Lipemia retinalisの臨床的特徴について

Clinical manifestations of lipemia retinalis

　自己免疫性溶血性貧血の21歳男性と，アルコール中毒の47歳女性に，V型高脂血症と網膜脂血症が発症した。2例共，視力，視野，色覚，暗順応，ERG, EOG等視機能の異常は認めなかった。眼底所見は網膜血管の淡紅色化，および光線反射の亢進と周辺部動静脈の乳白色化に伴う血柱反射の消失，周辺部網膜血管の区別困難，脈絡膜血管による紋理増強が観察され，血中脂質レベルの改善と共にこの所見は易可逆性であった。詳細な眼底所見を観察することにより，高脂血症の程度を予測することが可能であると思われた。

We observed lipemia retinalis in a 21-year-old male with autoimmune hemolytic anemia and a 47-year-old female with chronic alcohol toxicity. The hyperlipemia was of type V in both cases. No abnormal findings were elicited as to visual acuity, visual field, color vision, dark adaptation, electro-retinogram or electrooculogram.

Funduscopic features in both cases were char-acterized by pinkish appearance of vessels, in-creased light streak reflex, absence of blood col-umn reflex, ill-defined contour of vessels in the periphery due to milky whitening, and better visi-bility of choroidal vascular pattern. These findings disappeared after therapeutically induced decrease in triglyceride levels in the circulating blood. The triglyceride levels in the serum was 5,078 and 3,280 mg/dl respectively before treatment.

We thought that it is possible to determine the grade of hyperlipemia based on funduscopic find-ings.
