Ultrasound biomicroscopic patterns after glaucoma surgery in congenital glaucoma

Ultrasound Biomicroscopy in Glaucoma: An Update

“…[25][26][27] The correlation between UBM morphology and the effectiveness of filtering surgery is less convincing than previously demonstrated in adults, possibly underlining the importance of individual nonsurgical factors for prognosis in congenital glaucoma.…”

Ultrasound biomicroscopic characteristics of the anterior segment in primary congenital glaucoma

“…3 There are very few studies on ultrasound biomicroscopic characteristics of the anterior segment in eyes with primary congenital glaucoma. 4,5 The purpose of the present study was to find the anatomical correlation of anterior segment morphology as evaluated by ultrasound biomicroscopy with biometric parameters such as corneal diameter and axial length, which are consequences of globe stretching.…”

UBM-guided chamber angle surgery for glaucoma management: an experimental study

“…18 UBM is also a helpful diagnostic tool in eyes with primary or secondary dysgenetic glaucoma, in which visualization of the anterior chamber structures is often dramatically hindered by corneal opacities. [19][20][21] UBM has also been used to assess the effectiveness of pressure-reducing mechanisms following filtration surgery since scleral drainage routes and intrascleral reservoirs can be imaged by this form of ultrasound. [22][23][24][25][26] Ultrasound biomicroscopy of the chamber angle has to be orientated around the typical reflection patterns of specific anatomical landmarks, that is, the transition zone between sclera and cornea, ligamenta pectinata, and the ending of Descemet's membrane.…”

“…[22][23][24][25][26] Ultrasound biomicroscopy of the chamber angle has to be orientated around the typical reflection patterns of specific anatomical landmarks, that is, the transition zone between sclera and cornea, ligamenta pectinata, and the ending of Descemet's membrane. 19,20,27 However, the characteristic information supplied by conventional gonioscopy, such as the pigmentation of the trabecular meshwork with no specific ultrasound reflection pattern, is lost and would therefore be missed by the use of UBM alone. With a penetration depth of only 5 mm, UBM-guided intraocular surgery cannot be used to view a larger area of the anterior chamber.…”
