Summary
Occlusions of retinal veins (central and branch) represent multifactorialy-conditioned disease involving presumably older patients, in whom the changes of retinal vessels caused by hypertension and atherosclerosis present the most important pathophysiological factors for development of this disease. In last years, the intensive scientific research is focused to the explanation of the role of the defects of the coagulations cascade. Especially in younger patients, the most often mentioned defect of the coagulations cascade is called as APC-resistance. Up to 95 % of all patients with APC-resistance are carriers of so called Leiden mutation.
The aim of our study
was to establish the prevalence of the ACP-resistance in 92 patients with central or branch occlusion of the retinal vein verified by means of angiography treated at the Department of Ophthalmology, Faculty Hospital, Olomouc, Czech Republic, EU, during the period 1999–2005.The control group consisted of 40 patients without any vascular, eye-related disease.
In the group of patients with occlusion of the retinal vein, the prevalence of the APC-resistance was 10.9 % and in the control group 5 %. In the group of patients 55 years old and younger the prevalence of the ACP-resistance was 14.3 %, in patients older than 55 years it was 5.6 %. According to the relatively small groups of patients, the established difference did not reach the level of statistical evidence. Results of our study confirmed the conclusions of previously published papers that the prevalence of the APC-resistance is not significantly higher in patients with retinal vein occlusion according to the prevalence in controls.
Key words:
