Comparability of corneal thickness and opacity depth assessed by OCT and UBM.

Objective: To compare the measurement of central thickness and depth of involvement of opacity-bearing corneas at different intensities (mild, moderate, and dense) using different instruments: Visante and Optovue OCTs, ultrasound biomicroscopy (UBM), and ultrasound pachymetry (central thickness).

Methods: Sample of 102 eyes: 70 eyes (68.63 %) with corneal opacity; 32 eyes (31.

Observational study of intraocular lens tilt in sutureless intrascleral fixation versus standard transscleral suture fixation determined by ultrasound biomicroscopy.

Background: The position of the intraocular lens (IOL) is a major factor that affects the final visual acuity after cataract surgery. However, no prospective study has compared the IOL positions associated with the sutureless intrascleral technique and the standard transscleral suturing technique. The current study compared the IOL positions in the two techniques using ultrasound biomicroscopy (UBM) in vivo.

Comparisons of choroidal nevus measurements obtained using 10- and 20-MHz ultrasound and spectral domain optical coherence tomography.

Purpose:: To compare measurements of lesions clinically diagnosed as choroidal nevi using spectral domain optical coherence tomography (SD-OCT) and 10- and 20-MHz ultrasound (US).

Methods:: This prospective study, which was conducted between May 2011 and December 2011, evaluated eyes diagnosed with choroidal nevus via photographic documentation using 10- or 20-MHz A- and B-mode US (experienced examiner using both the transpalpebral technique and direct contact) or SD-OCT in the enhanced depth imaging mode (performed by a different examiner blinded to the US results). Anteroposterior (AP) and transverse (T) US sections corresponded to sections adjusted perpendicularly on SD-OCT.

Ultrasound Biomicroscopy Comparison of Ab Interno and Ab Externo Intraocular Lens Scleral Fixation.

Purpose. To compare ab interno and ab externo scleral fixation of posterior chamber intraocular lenses (PCIOL) using ultrasound biomicroscopy (UBM). Methods.

Composition of intraocular foreign bodies: experimental study of ultrasonographic presentation.

Purpose: To investigate the reliability of ultrasound in determining the size and identify the sonographic features and artifacts generated by intraocular foreign bodies of different materials.

Methods: Experimental study using 36 enucleated porcine eyes. Fragments of nine different compositions (wood, glass, plastic, cardboard, iron, aluminum, lead, powder and concrete) and similar dimensions (4 mm) were implanted via scleral incision into the vitreous cavity of 36 porcine eyes, four eyes were used for each material.

Application of anterior segment optical coherence tomography in pediatric ophthalmology.

Purpose. Application of anterior segment optical coherence (AS-OCT) in pediatric ophthalmology. Methods.

[Pilot project of computerization of charts of the extrinsic ocular motility sector of the Santa Casa of São Paulo].

Purpose: To develop a system of support to the research in the field of the computer science, based on the automatic search of information, on the percentage of patients with certain characteristics and the crossing of this information among themselves.

Methods: A computer with Pentium III 650 MHz processor, 128 MB RAM, 32 MB video plate, free 20 MB in the hard disk and fitted with Windows 98/2000/XP. The data base used to store the information is Interbase version 6.
