PURPOSE To determine the proper time frame in which to assess retinal attachment status and to evaluate the superior retinal attachment status by performing B-scan ultrasonography in different positions on patients who have undergone pars plana vitrectomy and gas tamoponade. METHODS In this prospective study, 23 patients (23 eyes) who had undergone pars plana vitrectomy and gas tamponade were...

BACKGROUND The purpose of this study was to evaluate the extension and traction effects of posterior vitreous detachment (PVD) complicated with retinal tears using spectral domain optical coherence tomography (OCT) and B-scan ultrasonography. METHODS Complete ophthalmological examination, B-scan ultrasonography and spectral domain OCT were performed in patients with acute PVD and retinal tear...

Ultrasonography is the only practical method for obtaining images of the posterior segment of the eye when the light-conducting media are opaque. In this study, 182 dogs with ocular abnormalities presented to the Department of Veterinary Surgery and Radiology from December 2008-August 2010 were included. All the animals were subjected to detailed ophthalmic examination and B-scan ultrasonograph...

AIM To evaluate the accuracy of axial length (AL) measurements obtained from immersion B-scan ultrasonography (immersion B-scan) for intraocular lens (IOL) power calculation in patients with high myopia and cataracts. METHODS Immersion B-scan, contact A-scan ultrasonography (contact A-scan), and the IOLMaster were used to preoperatively measure the AL in 102 eyes from 102 patients who underwe...

Diagnostic and differential diagnostic of orbital diseases are considered to be one of the most difficult problems in ophthalmology because most orbital pathologies display the same signs and symptoms. Condition of orbital tissues can be evaluated using three different radiology imaging techniques: A/B-scan ultrasonography, computed tomography, and magnetic resonance imaging. A/B-scan ultrasono...

The use of B-scan ultrasonography was first reported by Baum and Greenwood (I958), who described their results as equivalent to the first x rays. As they predicted, improvement in equipment and technique has led to increased resolution of ocular structure being obtained by B-scan ultrasonography. The clinical application of the B-scan has been described by Coleman and Jack (I973) and the reliab...

B-scan ultrasonograms of the anterior segment were performed on selected patients. The difficulties in imaging the anterior segment are discussed and the value of this technique is demonstrated by illustration of B-scans in different pathological conditions. This technique can often provide important information and allow an early and accurate prognosis.
