Abstract

The prevalence of bilateral POAG cases with asymmetric evolution was studied in a selected population. In addition, the haemorheology of the optic disc was investigated by means of two different methods (the Langham POBF system and Colour Doppler Imaging) to discover if there may be haemodynamic difference between the two eyes of a patient affected by bilateral but asymmetric POAG. The retrospective epidemiologic study was made on all the POAG patients observed at the Eye Clinic of the University of Milan between 1985 and 1992 (622 patients). The prevalence of bilateral asymmetric cases proved to be 5-6%. The haemodynamic study made on 12 cases at the Eye Department of Turin University with both POAG and Colour Doppler (although they are methods studying different vascular districts), confirms that there is a significant compromission of ocular blood flow in POAG patients, also when the condition is unequal in the two eyes. Such a compromission, however, appears to have no statistically significant difference between the more compromised eye and its fellow.
