Magnetic Resonance Imaging for Glaucoma Evaluation.

The damage caused by glaucoma has been extensively evaluated at the level of the retina and optic nerve head. Many advances have been shown in this field in the last decades. Recent studies have also proved degenerative changes in the brain involving the intracranial optic nerve, lateral geniculate nucleus, and visual cortex.

Evaluation of Glaucomatous Damage via Functional Magnetic Resonance Imaging, and Correlations Thereof with Anatomical and Psychophysical Ocular Findings.

Purpose: To evaluate the functional magnetic resonance imaging (fMRI) response to binocular visual stimulation and the association thereof with structural ocular findings and psychophysical test results in patients with glaucoma, and controls.

Methods: Cross-sectional study. Participants underwent a complete ophthalmic examination, including Humphrey 24-2 visual field (VF) testing and optical coherence tomography.

[Occupational trauma due to superficial corneal foreign body].

Purpose: To evaluate the epidemiology of superficial corneal foreign body.

Methods: Patients who were seen at the Emergency Service of the Federal University of São Paulo, from April/05 to June/05, were screened and those with superficial corneal foreign body were interviewed. Data regarding gender, age, occupation, employment status, availability and use of protective devices and supervision of their use were collected.

Effect of brimonidine tartrate 0.15% on scotopic pupil: controlled trial.

Purpose: The aim of this study was to evaluate the duration of the effect of one single dose of brimonidine tartrate 0.15% on pupil diameter, under scotopic conditions, when applied topically in 1 eye of normal subjects.

Methods: The eyes of 19 normal volunteers were randomized so that 1 eye had 1 drop of brimonidine tartrate 0.

Visual acuity, contrast sensitivity, reading speed, and wavefront analysis: pseudophakic eye with multifocal IOL (ReSTOR) versus fellow phakic eye in non-presbyopic patients.

Purpose: To compare the visual performance in the pseudophakic eye and the phakic eye in four patients who underwent unilateral intraocular lens (IOL) implantation.

Methods: Four patients presenting with unilateral cataract underwent ReSTOR (Alcon Laboratories, Ft Worth, Tex) IOL implantation in their nondominant eye, targeting emmetropia.

Results: Uncorrected near visual acuity was >20/32 in all operated eyes and best spectacle-corrected distance visual acuity was 20/16 for two eyes, 20/25 for one eye, and 20/32 for one eye.
