RESUMEN Objetivo: Identificar las características morfológicas y morfométricas de las capas de la córnea mediante microscopia confocal en pacientes diabéticos. Métodos: Se realizó un estudio descriptivo, comparativo, en 90 ojos, 60 de ellos pertenecientes a pacientes diabéticos (30 tipo 1 y 3...

Investigating the effect of intracameral cefuroxime on oxidative stress and apoptosis in the rat cornea

Arq. bras. oftalmol; 82 (4), 2019
ABSTRACT PURPOSE: We examined the effect of intracameral administration of cefuroxime on oxidative stress and endothelial apoptosis in rat corneal tissue. METHODS: In total, 30 rats were divided into 3 groups of 10 rats each (intracameral administration of cefuroxime 0.1 mg/0.01 mL (cefuroxime group); ...

Descemet's membrane endothelial keratoplasty with a simplified technique and low complication rate: the samba technique

Arq. bras. oftalmol; 81 (2), 2018
ABSTRACT Purpose: We report a simplified Descemet's membrane endothelial keratoplasty (DMEK) technique that involves safe and effective preparation and introduction, correct orientation, and easy unfolding of the donor graft inside the recipient anterior chamber. Methods: In this retrospective study, w...

Endothelial assessment of donated tectonic corneas: a viable option for posterior lamellar transplantation

Arq. bras. oftalmol; 81 (2), 2018
ABSTRACT Purpose: Donated corneas are classified as tectonic if there are defects within any layers of the cornea which would prevent a satisfactory visual outcome after transplantation. This study aimed to evaluate whether some tectonic corneas have sufficient endothelial characteristics to allow their...

Corneal endothelial cell density and pterygium: a cross-sectional study

Arq. bras. oftalmol; 80 (5), 2017
ABSTRACT Purpose: To investigate the effects of pterygium on corneal endothelial cell density in patients with unilateral pterygium. Methods: We performed a cross-sectional analysis of data from patients with unilateral pterygium who were selected from September 1, 2015 to July 31, 2016 at Hospital de ...

Serum levels of vitamin A, visual function and ocular surface after bariatric surgery

Arq. gastroenterol; 54 (1), 2017
ABSTRACT BACKGROUND Bariatric surgery is the most effective treatment for severe obesity, but the surgery increases the risk of developing nutritional deficiencies, such as vitamin A deficiency. In human metabolism, vitamin A plays a role in vision. OBJECTIVE To evaluate serum vitamin A, visual functio...

Visual outcomes after deep anterior lamellar keratoplasty using donor corneas without removal of Descemet membrane and endothelium

Arq. bras. oftalmol; 79 (6), 2016
ABSTRACT Purpose: The optical quality of the interface after deep anterior lamellar keratoplasty (DALK) using the big-bubble technique has been shown to be excellent, leading to results comparable to penetrating keratoplasty. However, there is little in the literature with respect to the controversy sur...

Comparison of 20% sulfur hexafluoride with air for intraocular tamponade in Descemet membrane endothelial keratoplasty (DMEK)

Arq. bras. oftalmol; 79 (5), 2016
ABSTRACT Purpose: To compare the effect of 20% sulfur hexafluoride (SF6) with that of air on graft detachment rates for intraocular tamponade in Descemet membrane endothelial keratoplasty (DMEK). Methods: Forty-two eyes of patients who underwent DMEK by a single surgeon (A.S.J.) at Wilmer Eye Institute...
