Methods: Forty eyes of 40 patients with PAC underwent detailed ophthalmic evaluation including applanation tonometry, gonioscopy, optic disc evaluation with +78D lens and achromatic automated perimetry. UBM was performed to evaluate angle parameters before and after LPI to study the trabeculariris angle (TIA), the angleopening distance at 500 mm (AOD) and the central anterior chamber depth (ACD...

Introduction: A case of discoloration a multifocal hydrophobic acrylic intraocular lens (IOL), which was explanted and exchanged as well underwent laboratory analysis, is reported. Patient Clinical Findings: The patient presented with corrected distance visual acuity 20/50 glare in the right eye 8 years after implantation. Slitlamp examination revealed nasally decentered IOL whitish-brownish ha...

An electro-optic phase modulator in a regenerative mode-locker configuration is demonstrated as the starting mechanism for a Kerr-lens mode-locked Ti:sapphire laser. Mode locking is initiated automatically, and the system is capable of pulses as short as 21 fs.

PURPOSE To establish the frequency of infantile cataract in the Low Vision Service of São Geraldo Hospital (HSG-HCUFMG) and to analyze basis of history, ophthalmologic examination and optical prescription in these patients. METHODS Retrospective study of infantile cataract recorded in the Low Vision Service from January/1992 to December/2002. Age, sex, race, age at the first evidence of leuko...

AIMS To investigate the changes in PAX6 expression in the developing human eye. METHODS Six developing human eyes from 6 to 22 weeks' gestation were evaluated. Frozen sections were immunohistochemically stained with monoclonal antibody to chick Pax6 (amino acids 1-223). To verify antibody specificity, western blot analysis was carried out using cell lysates from P19 cells transfected with the...

The design, analysis, assembly methods, and optical-bench test results for a miniature injection-molded plastic objective lens used in a fiber-optic confocal reflectance microscope are presented. The five-lens plastic objective was tested as a stand-alone optical system before its integration into a confocal microscope for in vivo imaging of cells and tissue. Changing the spacing and rotation o...

PURPOSE To recalculate the radiation doses delivered to structures of interest within the eye, i.e., the lens, tumor apex, 5-mm point, optic disk, and macula for patients treated with eye plaque radiotherapy on the Collaborative Ocular Melanoma Study (COMS) Medium Tumor Trial, using updated dosimetric data. METHODS AND MATERIALS Using the Plaque Simulator planning system, doses were recalcula...

The RING finger ubiquitin ligase seven in absentia homolog 2 (Siah2) was identified in the R7 photoreceptor cells of Drosophila melanogaster, and it regulates the stability of prolyl hydroxylase domains (PHDs), with a concomitant effect on HIF-1α availability in the hypoxia response pathway. We previously reported that the hypoxia response pathway contributes to eye development during the embry...

This study reports a case of calcific opacification on an implanted silicone intraocular lens (IOL) without asteroid hyalosis. A 72-year-old female was referred for blurred vision in her left eye. Her history showed she had undergone uneventful phacoemulsification with in the bag implantation of a silicone foldable hydrophobic IOL (CeeON 911A, Pharmacia Corporation) 39 months earlier. Under sli...
