Analysis of changes of ultrasonic image and hemodynamics of retrobulbar blood vessels in Coats disease

, : Analysis of changes of ultrasonic image and hemodynamics of retrobulbar blood vessels in Coats disease. Chinese Journal of Ophthalmology 46(9): 791-794

To analyze the changes of color Doppler flow imaging (CDFI) and hemodynamics of retrobulbar blood vessels in Coats disease. It was a prospective and self-comparative study in which 18 cases (18 eyes) were included. Axial eye length was measured with A scan. Routine CDFI was performed in all cases. We examined ophthalmic arteries (OA), central retinal arteries (CRA) and posterior ciliary arteries (PCA) by CDFI, and recorded the peak systolic velocities (PSV), end diastolic velocities (EDV), time averaged maximum velocities (TAMX), pulsatility indexes (PI) and resistance indexes (RI) in all cases. Each hemodynamic parameter in the affected eye (21.36 ± 1.19) mm was compared with those in the contralateral normal eye (controls). T-test was used for the estimation of significance of the difference between the diseased and normal eyes. The axial length in diseased eyes was significantly shorter than that of the controls (22.92 ± 1.09) mm (t = 3.617, P < 0.05). The changes of CDFI in diseased eyes included retinal detachment, retinal cyst, subretinal organization, etc. Vitreoretinal traction, intraocular ossification and calcification were uncommon. The PSV (6.96 ± 1.21) cm/s and EDV (1.99 ± 0.36) cm/s in the diseased eyes were significantly lower than the PSV (8.30 ± 1.46) cm/s and EDV (2.48 ± 0.47) cm/s in the control eyes (t = 2.995, 3.476;P < 0.05). No significance difference was present in other hemodynamic parameters between diseased and normal eyes. Coats disease is a congenital disease that may influence the development of the eye. The ultrasonography is helpful for the diagnosis and differential diagnosis in Coats disease. Low perfusion of the central optic artery might exist in Coats disease. The hemodynamics changes in Coats disease require further studies.
