Axial eye length assessment in silicone oil-filled eyes

Purpose: To compare the reliability of axial eye length [AEL] measurement in silicone oil-filled phakic eyes by conventional B-scan ultrasonography through the eyelid, after a correcting factor, to partial coherence interferometry [PCI] measurement

Methods: A prospective and comparative study was performed at Al-Zahraa University Hospital clinic from [January 2016 - December 2016]. In total 13 phakic eyes of 13 patients who underwent vitrectomy and silicone oil filling were enrolled into the study. AEL was measured by B-scan and compared to measurement by PCI

Results and Conclusions: There was no significant difference in AEL measurement by either B-scan ultrasonography through the eyelid, after a correcting factor, and PCI

Hallermann-streiff syndrome a case report from Egypt

Hallermann-Streiff syndrome [HSS] is a rare genetic disorder that is primarily characterized by distinctive malformations of the skull and facial [craniofacial] region; sparse hair [hypotrichosis]; eye abnormalities; dental defects; degenerative skin changes [atrophy], particularly in the scalp and nasal regions; and proportionate short stature. Here we describe a case with HSS

Echographic evaluation of optic disc excavation

To evaluate the role of high resolution B-scan echography in differentiating the causes of optic disc excavation. A prospective study was conducted on 30 subjects presenting to Al-Zahraa University Hospital [2009 - 2011] with optic nerve excavation. Of these patients 10 with coloboma, 10 with cup-shaped posterior staphyloma and 10 with glaucomatous optic nerve cupping were identified. Horizontal and vertical approaches for optic disc excavations were evaluated using B-scan echography. Specific echographic criteria for excavation configurations were successfully estimated. High-resolution contact B-scan echography may provide useful differentiation for optic disc excavations in eyes with opaque media
