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. ...

Refractive and visual outcomes after Ferrara corneal ring segment implantation at a 60% depth in keratoconic eyes: case series

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: This report addresses refractive, topographic, visual acuity, and optical coherence tomography outcomes 12 months after femtosecond, laser-assisted insertion of Ferrara intrastromal corneal ring segments in keratoconic eyes at a depth of 60%. Methods: Interventional, prospective, non-...

Orthokeratology on patient with ectasic cornea

Rev. bras. oftalmol; 78 (5), 2019
Abstract A 26-year-old man, single, business student, reveals a ectasic cornea during corneal topography exam. Among some procedures, the patient chose Orthokeratology to do a corneal reshape and got successfully a good visual acuity, going against the most authors guidance....

RESUMEN Objetivo: Determinar las características topoaberrométricas del queratocono. Métodos: Se realizó un estudio observacional descriptivo de corte transversal que comprendió 101 topografías corneales de pacientes diagnosticados de queratocono con el topógrafo corneal Magellan Plug and Play (n...

Catarata y queratocono: una sorpresa refractiva
Cataract and keratoconus: a refractive surprise

Rev. cuba. oftalmol; 32 (1), 2019
RESUMEN El queratocono es una ectasia corneal bilateral en la cual la córnea asume una forma cónica irregular teniendo en cuenta su afinamiento y protrusión. Su etiología es probablemente multifactorial. Está considerada una enfermedad rara por su baja incidencia; no obstante, se considera que esta ...

Posterior keratoconus and iris atrophy: a fortuitous association?

Arq. bras. oftalmol; 82 (1), 2019
ABSTRACT The authors describe an unusual association between posterior keratoconus and iris atrophy, confirmed by a complete ocular evaluation, scheimpflug imaging and pachymetric curve. A hypothesis for concomitant findings is discussed....

Effect of accelerated corneal crosslinking on ocular response analyzer waveform-derived parameters in progressive keratoconus

Arq. bras. oftalmol; 82 (1), 2019
ABSTRACT Purpose: To evaluate the effect of accelerated corneal crosslinking on corneal biomechanics with an ocular response analyzer in patients with progressive keratoconus. Methods: In this retrospective study, 50 eyes of 45 patients with progressive keratoconus who underwent accelerated corneal cro...
