 Purpose: To assess orbital color Doppler ultrasonography (CDU) parameters of patients with manifest hyperopia in comparison to the emmetropes

 Methods: Forty eyes of 40 patients presenting with manifest hyperopia were included into the study. Forty eyes of 40 emmetropes healthy volunteers also were examined as the control group. We have evaluated ophthalmic artery (OA), central retinal artery (CRA), posterior ciliary artery, central retinal vein (CRV), and superior ophthalmic vein (SOV) flow velocities and resistance indices (RI).

 Results: RI value in the OA and mean velocities (MV) in the SOV were significantly higher in the group of manifest hyperopia. CDU parameters of the CRA, CRV, nasal and temporal posterior ciliary artery (nPCA, tPCA)) between hyperopic group and the control group were statistically insignificant.

 Conclusion: Doppler ultrasonography findings revealed that some orbital CDU parameters are altered in eyes with manifest hyperopia compared to emmetropia. Particularly, increased RI suggested the possibility that increased choroidal vascular resistance may be associated with the pathological angiogenesis in the affected eye.
