Abstract Ultrasound Biomicroscopy a new imaging technology that uses high frequency ultrasound and thus allows imaging the anterior portion of the globe in microscopic resolution. It is independent on the clarity of the optical media and allows, for the first time, a non-invasive demonstration of the anterior position of the globe. Our study aims to evaluate the anterior segment of eyes of primary congenital glaucoma by U.B.M thus confirming the diagnosis and assising the surgical planning. In this study thirty six eyes, 18 eye diagnosed as primary congenital glaucoma group A and 18 non glaucomatous eyes as control group B selected from out patient clinic of Ophthalmology Center of Mansoura University. They were subjected to full Ophthalmological examination under general anesthesia including microscopic examination, direct ophthalmoscope for C/D ratio, Horizontal corneal diameter measurement by use of caliper, schiotz tonameter for lOP measurement, conventional ultrasound for axial length and Ultrasound Biomicroscopy examination. group A and group B were subjected to U.B.M ’examination U.B.M of both groups were compared in and non dete U.B plan corn The the betv effe pro: coniglautrab morphology and measurement of corneal thickness, AC depth and angle. Combined trabeculotomy, trabeculectomy was performed to all group A by only one surgen. U.B.M examination revealed a significant variation in ,morphology between the two groups, also statistical study of the measurement and lOP was done and it was highly significant. In group A effectiveness of the filtering surgery evaluated by U.B .M. The presence of area of hypodensity at the treated area was also obvious in all success cases also scleral rote had been noted. Decrease of corneal thickens and lOP was highly significant, but anterior chamber depth and angle was insignificant, the thickness of filtering bleb was insignificant because the success depends more on the reflectivity of the filtering bleb. |
