Influence of upper blepharoplasty on intraocular lens calculation

Arq. bras. oftalmol; 84 (1), 2021
ABSTRACT Purpose: To determine the effect of upper blepharoplasty on corneal topography and intraocular lens power calculation using Galilei and IOLMaster. Methods: Thirty patients submitted to upper blepharoplasty from May 2014 to March 2017 at the Hospital Oftalmológico de Sorocaba (São Paulo, Braz...

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...

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...

Anterior chamber characteristics assessed by rotating Scheimpflug imaging in patients with retinitis pigmentosa

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: The aim of this study was to evaluate anterior segment parameters and corneal aberrations in patients with retinitis pigmentosa using Scheimpflug imaging and to compare the findings with those for healthy controls. Methods: This single-center, case-control study included patients diag...

Whole-exome sequencing in familial keratoconus: the challenges of a genetically complex disorder

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: The underlying genetic causes of keratoconus are essentially unknown. Here, we conducted whole-exome sequencing in 2 Brazilian families with keratoconus. Methods: Whole-exome sequencing was performed on 6 keratoconus-affected individuals of 2 unrelated pedigrees from Southern Brazil. ...

Evaluation of corneal layers and anterior sclera in patients with primary Sjögren's syndrome

Arq. bras. oftalmol; 82 (4), 2019
ABSTRACT Purpose: We aimed to compare the thickness of anterior sclera, corneal layers, and pre-ocular tear film between patients with primary Sjögren's syndrome and healthy individuals. Methods: Fifty-one patients with primary Sjögren's syndrome and 41 healthy control participants were recruited in ...

Corneal Astigmatism in cataract surgery candidates

Rev. bras. oftalmol; 77 (5), 2018
Abstract Purpose: To report the prevalence and analyse corneal astigmatism patterns in cataract surgery candidates. Methods: Researchers examined 2136 eyes from 1204 patients for cataract surgery from 1 January to 31 December 2016. All the candidates were evaluated with partial coherence interferometry...

Analysis between two optical biometric devices in patients with cataract

Rev. bras. oftalmol; 77 (4), 2018
ABSTRACT Objective: To evaluate the correlation of optical biometry and target with variable ages, anterior chamber depth, axial length, R1/K1 and R2/K2 established by two optical biometry devices in patients with cataract. Methods: The study included the analysis of 348 medical records, from which 503 c...

Degeneração marginal pelúcida superior

Rev. bras. oftalmol; 77 (3), 2018
Resumo A degeneração marginal pelúcida (DMP) é uma ectasia corneana rara. Caracteriza-se por afinamento periférico, sem sinais inflamatórios, tipicamente inferior e bilateral, separado do limbo por área de espessura normal. Há protrusão da córnea acima da área de afinamento, resultando em elev...

Análise da curvatura corneana após exérese de pterígio: o impacto do procedimento cirúrgico de forma objetiva em nossa prática

Rev. bras. oftalmol; 77 (2), 2018
Resumo Introdução: O pterígio é uma proliferação de tecido fibrovascular centrípeta, que avança da conjuntiva bulbar em direção ao centro da córnea. A excisão do pterígio pode causar melhora na acuidade visual. A excisão cirúrgica tem como objetivo atingir uma superfície ocular topografi...
