Profundidad de la línea de demarcación del estroma corneal después de la reticulación del colágeno corneal usando epitelial corneal personalizado versus convencional desbridamiento
Corneal stromal demarcation line depth after corneal collagen cross-linking using customized versus conventional corneal epithelial debridement

Prensa méd. argent; 106 (7), 2020
Aim of the Study: Compare the corneal demarcation line (DL) depth after corneal collagen cross-linking (CXL) with subtotal versus customized corneal epithelium debridement using anterior segment optical coherence tomography (AS-OCT). Design: Prospective case-control study. Materials and Methods: The stud...

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...

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...

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...

Six-month outcomes of corneal crosslinking with dextran-free isotonic riboflavin solution

Arq. bras. oftalmol; 79 (3), 2016
ABSTRACT Purpose: To analyze the short-term clinical and topographic outcomes in patients with keratoconus after corneal collagen cross-linking treatment (CXL) with dextran-free isotonic riboflavin solution. Methods: In this retrospective case series, 26 eyes from 26 patients with keratoconus were stud...

Descriptive analysis of the type and design of contact lenses fitted according to keratoconus severity and morphology

Arq. bras. oftalmol; 79 (2), 2016
ABSTRACT Purpose: Keratoconus is characterized by bilateral asymmetrical corneal ectasia that leads to inferior stromal thinning and corneal protrusion. There is currently a lack of consensus regarding the most efficacious method for fitting contact lenses in patients with keratoconus, given the various...

Perfuraçäo em degeneraçöes ectásicas da córnea
Perforation in ectatic corneal degenerations

Arq. bras. oftalmol; 57 (6), 1994
A degeneraçäo marginal de Terrien, a degeneraçäo marginal pelúcida e o ceratoglobo säo patologias ectásicas da córnea. Essas degeneraçöes produzem áreas de afinamento periférico que causam ectasia, astigmatismo irregular e maior suscetibilidade a perfuraçöes corneanas. Säo apresentados 4 c...

Ceratocone recidivado: estudo clínico e histo-patológico
Recurrent keratocomus: clinical and histopathological study

Arq. bras. oftalmol; 51 (3), 1988
Os autores descrevem um caso de recidiva clínica bilateral de ceratocone em córneas transplantadas há 24 anos no olho direito e há 28 anos no olho esquerdo. Após re-transplante penetrante no olho esquerdo, a córnea retirada foi encaminhada para exame anátomo-patológico, e o diagnóstico foi compr...
