revealed a hyperechoic choroidal lesion with acoustic shadowing.
following open globe repair.
Diagnostic B-Scan Ultrasonography
was performed in these patients preoperatively.
Among the topics are color vision and color blindness, slit-lamp examination, corneal confocal microscopy, optic disc assessment in glaucoma, indocyanine green angiography, A-scan and B-scan ultrasonography
, electrophysical tests for assessing visual function, anterior segment optical coherence tomography, localizing an intra-ocular foreign body, diagnostic procedures for genetically transmitted eye diseases, diagnostic modalities in intra-ocular malignancies, and ocular motor nerve palsies.
6) Technologies such as autofluorescence, OCT, and B-scan ultrasonography
are helpful in differential diagnoses, viewing clefts, and uncovering the integrity of the surrounding retinal structures.
In this respect, imaging technology, such as B-scan ultrasonography
, UBM, CT, or MRI can discover eye tumors and avoid misdiagnosis.
showed that the tumor measured 11.
In B-scan ultrasonography
a two dimensional cross section of the eye and orbit is obtained (Figure 1).
With imaging tests such as B-scan ultrasonography
, fundus fluorescein angiography, computed tomography, fundus autofluorescence as well as the recently developed technology of optical coherence tomography, it is possible to examine in detail the structure and location of ODD and quantitatively follow changes over time (see pages 232236).
is an important tool for evaluating the posterior segment in eyes with opaque media and provides a method of assessing the structural changes in the posterior segment of the eye in such patients.
Preoperative assessment included best- corrected visual acuity (BCVA), funduscopy with 90D lens and B-Scan ultrasonography
in 9 patients was used as fundus was not visualized clinically.
