Relationships between corneal biomechanics and the structural and functional parameters of glaucoma damage

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To investigate the relationships between (i) thickness of the retinal nerve fiber layer, optic nerve head topography, and visual field parameters and (ii) corneal biomechanical properties in normal controls and patients with ocular hypertension and primary open-angle glaucoma. Methods...

Corneal differences between healthy and subclinical patients assessed using two diferente corneal tomographers

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To analyze subclinical keratoconus topography indexes using Pentacam and Orbscan-II measurements to identify evidences for seeking sensitive indexes to screen and diagnose subclinical keratoconus. Methods: Fifty healthy participants (50 eyes) and 40 patients with subclinical keratocon...

Inter-eye osmolarity differences in patients with symptomatic and non-symptomatic dry eyes

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To analyze whether inter-eye osmo larity differences were related to dry eye symptomatology. Methods: A total of 135 participants were randomly recruited from those who visited in the Optometry Clinic of the Optometry Faculty (Universidade de Santiago de Compostela). In a single sche...

Biomechanics in DALK: Big bubble vs manual lamellar dissection

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: The present study's aim was to compare the biomechanical properties of corneal tissue in patients who underwent deep anterior lamellar keratoplasty (DALK) surgery, with successful big bubble formation and manual lamellar dissection, during failed big bubble formation. Methods: This re...

Comparing the postoperative refractive predictability of Pentacam HR and IOLMaster 500 after a multifocal intraocular lens implantation

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To compare the postoperative refractive predictability of IOLMaster 500 and Pentacam HR on the basis of keratometry and anterior chamber depth values in eyes with an indication for multifocal intraocular lens (IOL) implantation. Methods: This was a retrospective study conducted on 118...

Optical coherence tomography angiography findings in patients with branch retinal vein occlusion treated with Anti-VEGF

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To investigate retinal microvasculature changes in patients treated with anti-VEGF for macular edema secondary to branch retinal vein occlusion. Methods: We examined 38 eyes of 19 patients for the study. We measured superficial and deep capillary plexus vessel densities (%), foveal av...

Valores de referencia de analitos en orina en la edad pediatrica

La deteccion de trastornos metabolicos minerales puede explicar diversas anomalias fisiologicas que exigen para su interpretacion la comparacion con valores de referencia validados. El objetivo de este trabajo fue la determinacion de valores de referencia en la poblacion infantil uruguaya, de los analito...
