summary

Intraocular white pupil, congenital cataract, retinal detachment, retinoblastoma, exudative retinitis, retrolenticular fibrous hyperplasia, congenital persistent first vitreous body, empyema of anterior chamber and vitreous abscess secondary to systemic infection. What effect does the ultrasonic examination of eyeball and orbit have? Next, I'd like to share my views with you.

What effect does the ultrasonic examination of eyeball and orbit have?

Color Doppler ultrasound and pulse Doppler, especially high-grade color ultrasound diagnostic instrument can be used to analyze ocular artery hemodynamics. The maximum blood flow velocity, average blood flow velocity, velocity integral, resistance index and pulsatility index can be displayed by microcomputer.

Ultrasound has special diagnostic value for retinal detachment and retinoblastoma, and the diagnostic coincidence rate can reach 98%. Both metal and nonmetal can be displayed; ② The location of the foreign body can be clearly identified as the wall of the eyeball, inside the eyeball or outside the eyeball;

Intraocular white pupil, congenital cataract, retinal detachment, retinoblastoma, exudative retinitis, retrolenticular fibrous hyperplasia, congenital persistent first vitreous body, empyema of anterior chamber and vitreous abscess secondary to systemic infection. The clinical manifestations of these lesions are similar, but the sonograms are different.

matters needing attention

(1) More than 95% of the tumors can be diagnosed qualitatively, but ultrasound can't show the size and invasion of bone wall. Therefore, it is necessary to combine other imaging examinations, such as CT and MRI, to make a comprehensive diagnosis. (2) ultrasonography can provide some information for primary meningioma, but it is difficult to diagnose secondary meningioma.
