Ultrasound Biomicroscopy in Silicone Oil-Filled Eyes

Abstract

Easily recognizable, distinct UBM patterns are characteristic of conditions found in silicone oil-filled eyes. Ultrasound biomicroscopy seems to be a useful tool for assessing changes in silicone oil-filled eyes.

Characteristics of Silicone Oil Emulsification After Vitrectomy for Rhegmatogenous Retinal Detachment: An Ultrasound Biomicroscopy Study

“…UBM was performed by experienced ophthalmologists using the protocol described by Grigera et al ( 8 ) and Avitabile et al ( 9 ) UBM was performed with the patients lying in a supine position. The gain was set at 81 dB.…”

“…All UBM images were analyzed by two independent readers. The extent of SO emulsification detected by UBM was classified according to the method described by Grigera et al ( 8 ). The following five signs were considered to indicate SO emulsification.…”

“…Using the horizontal central scan image, floating droplets, endothelial deposits with a fixed status, ghost images, and hyperoleon were graded as 1 (present) or 0 (not present) ( 8 ). The area of hyperoleon was measured using ImageJ software (National Institute of Health, Bethesda, MD, USA) ( Figure 2 ).…”

“…UBM can be used to take high-resolution images of the anterior segment and has improved our understanding of many ocular diseases, especially glaucoma. Azzolini et al ( 7 ) and Grigera et al ( 8 ) described the UBM findings of SO emulsification in the anterior segment. However, those studies did not fully explore the correlations between UBM findings and other clinical characteristics, such as glaucoma.…”

Ultrasound Biomicroscopy (UBM) in Glaucoma Filtering Surgery: An Image Walkthrough

“…UBM has been usefully employed in diverse aspects and conditions related with glaucoma: for assessing angle configuration in suspects of angle closure and closed-angle glaucoma, [4][5][6][7][8] for the evaluation of the effect of laser iridotomy in narrow angles 9,10 for the recognition of angle structures and of angle and anterior segment anomalies in congenital glaucomas, 11,12 of angle recession and other lesions in traumatics glaucoma, 13 pigmentary dispersion and pigmentary glaucoma, 14,15 in silicone oil-filled eyes with glaucoma 16 and in eyes with opaque grafts with post-penetrating keratoplasty glaucoma. 17 Of the published literature on UBM and glaucoma filtering surgery, a group of papers deal with non-penetrating surgery, [17][18][19][20][21] other with trabeculectomy, 23,24 and another one with the followup of glaucoma surgery complications.…”
