Materials and Methods: 25 patients hospitalized for eye injury and elevated IOP were evaluated 24 months after the trauma. All injured and fellow eyes underwent IOP measure, visual field (HFAII, Central 30/2SITA), pulsatile ocular blood flow analysis (POBF, OBF Labs UK), CDI examination (PSV, EDV, and RI) of Ophthalmic Artery, Central Retinal Artery, Short Posterior Ciliary Arteries. Results: IOP was significantly higher in injured eyes (15.1 vs 13.0±2.7mmHg) (P= 0,01), but only 2 eyes (8.8%) were under medical treatment POBF values were significantly lower in injured eyes: 11,25 μl/s in traumatised eyes and 15,40 μl/s in fellow eyes (P = 0.002). Resistivity Index (RI) of all investigated retrobulbar vessels was very significantly higher in injured eyes than in fellow eyes (P= 0.0001). There is no significant correlation between IOP and ocular blood flow disturbances.展开更多
