Análise comparativa entre os índices tomográficos em pacientes com ceratocone inicial

Rev. bras. oftalmol; 80 (3), 2021
RESUMO Objetivo: Avaliar sensibilidade do volume corneano, asfericidade e índice D para o diagnóstico precoce de ceratocone. Métodos: Estudo transversal analítico, realizado entre dezembro de 2018 e outubro de 2020, no qual foram analisados os prontuários de 39 pacientes (78 olhos) diagnosticados ...

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...

RESUMEN Objetivos: Determinar las modificaciones tomográficas en pacientes con queratocono tratados con crosslinking corneal en 8 años de evolución. Métodos: Se realizó un estudio descriptivo, longitudinal y retrospectivo de 58 ojos pertenecientes al mismo número de pacientes con queratocono prog...

Evaluation of anterior segment parameters using Scheimpflug technology during the Valsalva maneuver in patients with keratoconus

Arq. bras. oftalmol; 79 (6), 2016
ABSTRACT Purpose: This study aimed to explore the effects of the Valsalva maneuver (VM) on ectatic corneas during anterior segment tomography scans using a Scheimpflug camera. Methods: This prospective observational study included 100 eyes of 50 patients with bilateral keratoconus (KC). Anterior segmen...

Differentiation of mild keratoconus from corneal warpage according to topographic inferior steepening based on corneal tomography data

Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT We report two cases of suspicious asymmetric bow tie and inferior steepening on topographic evaluations with reflection (Placido) and projection (Scheimpflug). Rotating Scheimpflug corneal and anterior segment tomography (Oculus Pentacam HR, Wetzlar, Germany)® was performed in the first case, w...
