Ultrasound biomicroscopy in glaucoma

Acta Ophthalmologica, 1992
Abstract Ultrasound Biomicroscopy is a newly developed high resolution imaging method that uses high frequency ultrasound (50–100 MHz). Tissue penetration is about 4 mm. This method allows detailed observation of anterior and posterior chamber anatomy in the living eye, and is thus a useful tool in both clinical assessment of glaucoma, and research ...

Ultrasound biomicroscopy in scleritis

Ophthalmology, 1998
This study aimed to investigate the usefulness of ultrasound biomicroscopy (UBM) for detecting and following up scleritis and episcleritis.The study design was a case series.Patients with scleral inflammatory diseases (n = 16) were examined.Patient-reported problems and slit-lamp and UBM (50-MHz transducer) findings were compared retrospectively for ...

Ultrasound Biomicroscopy of Eyelid Lesions

Ophthalmologica, 2003
This study compared ultrasound biomicroscopy with histopathology in discerning depth of eyelid lesions and tissue characteristics. Ultrasound biomicroscopy (50 MHz) was used to analyze lesion depth and tissue characteristics of eight patients with eyelid lesions referred to a university-based referral practice prior to excisional biopsy.

Ultrasound Biomicroscopy in Infantile Glaucoma

Ophthalmology, 1997
Glaucoma in infants has many causes: Evaluation of the anatomy of the anterior segment of eyes with infantile glaucoma may help to determine the pathogenesis of an infant's disease and influence therapeutic decisions.Eleven eyes of six infants with glaucoma were evaluated with ultrasound biomicroscopy (UBM) to evaluate the anatomic characteristics and ...

Keratoconus Staging with Ultrasound Biomicroscopy

Ophthalmologica, 1998
The diagnosis of keratoconus is based on slip-lamp and keratometric findings, and its classification includes 4 different stages. In this study, we compare the ultrasound biomicroscopy (UBM) findings and the keratoconus index (KI) determined using UBM with the severity of the disease.

Ultrasound biomicroscopy in iris lesions

Der Ophthalmologe, 1999
It is difficult to classify lesions of the iris, especially when they are posterior or in the iridociliary angle of the eye.We used an ultrasound biomicroscope (Humphrey, Zeiss, Oberkochen, Germany) with a high-frequency sound head (30 and 50 Hz). This study included all patients with unspecified iris processes who were examined at the University Eye ...

Ultrasound Biomicroscopy in Pars Planitis

American Journal of Ophthalmology, 1996
To report the diagnosis of pars planitis on the basis of ultrasound biomicroscopy images.The Humphrey ultrasound biomicroscope was used for examination of the right eye of a 17-year-old boy, referred to our clinic because of blurred vision. The lens showed a posterior subcapsular cataract precluding fundus visualization.Ultrasound biomicroscopy showed ...

Clinical Use of Ultrasound Biomicroscopy

Ophthalmology, 1991
The authors have developed a method of obtaining images of cross-sections of the intact anterior globe at microscopic resolution. High-frequency ultrasound transducers (50-100 MHz) have been developed and incorporated into a clinical B-scan device capable of producing images in the living human eye to a depth of approximately 4 mm at an axial and ...

In vivo biomicroscopy with ultrasound

Ultrasonics, 1987
We propose the use of inverse scattering theory methods to analyse high frequency ultrasound reflection data to provide high resolution images of living tissue. Conventional ultrasound imaging uses the pulse-echo method which can only resolve structures which are large compared to the wavelength of the ultrasound.

Ultrasound Biomicroscopy in Lens “Coloboma”

European Journal of Ophthalmology, 2003
Purpose To study the morphology of the Lens “Coloboma” using the technique of ultrasound biomicroscopy. Methods We used the Paradigm 40 Ultrasound biomicroscope to study the morphology of the lens “Coloboma”. Results Ultrasound biomicroscopy of the lens “Coloboma” revealed a greatly increased sphericity of the lens and the deficiency of zonules in the “
