The protein moiety of lipoprotein (a) consists of apoB-100 and apolipoprotein (a). Lipoprotein (a) is an independent risk factor for premature atherosclerosis. Apolipoprotein (a) and plasminogen are structurally homologous. Through interference with the fibrinolytic system, lipoprotein (a) may act as a thrombogenic factor. In the present study, we determined lipoprotein (a) concentrations in 84 patients (60 men and 24 women) with retinal vascular occlusion (RVO) and in 2 groups of healthy volunteers (n = 40 and 46). In all, 29% of the patients had Lp (a) levels of above 300 mg/l. In the two reference groups, only 10% and 9% of the subjects exceeded this level. According to the chi-square test, the association between Lp (a) levels and RVO was significant. Lp (a) concentrations did not differ between patients with arterial occlusion and those with venous occlusion. No difference in the total cholesterol, triglyceride, or LDL-cholesterol values was observed between patients and controls. We therefore conclude that Lp (a) represents an independent risk factor for RVO.

Retinal vascular occlusions are occlusion of the R.C.A. or of the branches with a dramatic loss of the visual function immediately; occlusion of R.C.V. or of the branches, less dramatic at once but a follow up is necessary for a long time because of neovascular complications or macular edema; the most frequent aetiology is also the atherosclerosis. The treatment is the treatment of atherosclerosis or of a particular aetiology. Treatment of the ischemic syndrome is supported by Argon laser for retinal photocoagulation.

Central retinal artery occlusion occurs most commonly between the ages of 50 and 70 years, and nearly one-half (45%) of patients also have carotid artery disease. Other causes of vision-threatening vascular disease include atherosclerosis, embolism, hypertension, diabetes mellitus, and valvular disease. Symptoms vary, depending on the ocular structures involved. The patient's symptoms are an important clue to the diagnosis of peripheral or posterior retinal vascular occlusion, macular blood vessel disease, intravitreal hemorrhage, optic nerve ischemia, and ocular ischemic syndrome. The patient's ocular symptoms should lead to investigation for clinical signs of ocular vascular disease (eg, hemorrhage, "hard" or "soft" exudates, neovascularization, retinal edema, pallor, emboli, vessel narrowing, or atriovenous crossing changes).
