Corneal topographic alterations in women with endometriosis: data analysis in an ophthalmologic clinic

Rev. bras. oftalmol; 83 (), 2024
ABSTRACT Objective: To verify whether there are pathological dysfunctions in the cornea of patients with endometriosis. Methods: Case-control research with a quantitative approach that compared topographic and tomographic examinations of the cornea of patients with a laparoscopic diagnosis of endometri...

Treatment of irregular astigmatism by topography-guided ablation

Rev. bras. oftalmol; 83 (), 2024
ABSTRACT Topography-guided ablation was designed to improve corneal regularity throughout the correction of corneal high order aberrations. The present report described three cases with different indications for topography-guided ablation to correct irregular astigmatism. The patients were monitored in t...

Unexpectedly high corneal flap thickness and ectasia after mechanical LASIK

Rev. bras. oftalmol; 82 (), 2023
ABSTRACT LASIK is a refractive surgical procedure in which a corneal flap is created to expose the corneal stromal bed. Preoperative estimation of corneal flap thickness is necessary to calculate the percentage tissue altered in LASIK, an important quantitative risk factor for ectasia. The objective of t...

Belin/Ambrósio Enhanced Ectasia Display in cataract surgery and relation to final visual acuity

Rev. bras. oftalmol; 81 (), 2022
ABSTRACT Objective To analyze and describe the coefficients found on maximum Ambrósio Relational Thickness-Maximum (ART-Max) and Belin/Ambrósio Enhanced Ectasia Display total deviation (BAD-D) in eyes with normal corneal topography subjected to cataract surgery with premium intraocular lens implantat...

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...

Causes of congenital corneal opacities and their management in a tertiary care center

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To evaluate causes and management of congenital corneal opacities (CCO) diagnosed in a tertiary care eye center and to compare the data with a previous study at the same institution. Methods: Computerized medical records in all patients with congenital corneal opacities diagnosed in t...

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...

Centration in refractive surgery

Arq. bras. oftalmol; 83 (1), 2020
ABSTRACT The point of centration for refractive surgery is a theme of great importance that generates considerable discussion among specialists and surgeons in the field. Notably, any changes in light can alter the size of the pupil, and the visual axis of the fixation line to the fovea is unique in each...

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...
