Factors influencing endothelial cell density of corneas for transplantation.

To evaluate factors affecting corneal endothelial cell density (ECD) under enucleation and preservation time studies at Eye Bank of the Federal District of Brazil. We conducted a case-control study collecting data from 1128 corneas where death-to-enucleation time and enucleation-to-preservation time were within 24 h. Low cell count were those corneas with an ECD less than 2000 cells/mm and high cell count was defined as those with ECD greater than 2000 cells/mm.

Reproducibility of peripapillary retinal nerve fiber layer thickness measurements using spectral domain OCT in Brazilian patients.

Purpose: To evaluate the reproducibility of peripapillary retinal nerve fiber layer (RNFL) thickness measurements in normal eyes and eyes with glaucoma using spectral domain optical coherence tomography (SDOCT).

Methods: One eye of 79 normal and 72 glaucoma patients was analyzed. All patients underwent a complete ophthalmological examination, including visual acuity testing; intraocular pressure, slit-lamp examination, indirect ophthalmoscopy; and the glaucoma group underwent achromatic perimetry with the 24-2 SITA Fast Humphrey Field Analyzer.

Botox® after Botox® - a new approach to treat diplopia secondary to cosmetic botulinic toxin use: case reports.

A new technique for the treatment of diplopia secondary to cosmetic botulinum toxin A use is described. In this interventional case reports, two consecutive patients who developed diplopia after periocular cosmetic use of botulinum toxin A were treated with intramuscular botulinum toxin A injection into the antagonist extraocular muscle. Diplopia resolved in both patients in less than 1 week with no side effects or complications.

Posterior amorphous corneal dystrophy: ultrasound biomicroscopy findings in two cases.

We present two cases of posterior amorphous corneal dystrophy in members of the same family. We correlated the clinical findings with refraction, topography, and ultrasound biomicroscopy (UBM). This is the first report of UBM findings in amorphous corneal dystrophy and we describe the depth of stromal opacification measured in this exam.
