RESUMEN: El SARS CoV-2, agente causal de la enfermedad llamada Covid-19, infecta las mucosas digestivas y respiratorias, afectando las células epiteliales. El virus ingresa a través del receptor de membrana ACE2 provocando la disrupción de la homeostasis celular. Frecuentes reportes indican la presenc...
RESUMO O Lasik é a técnica de cirurgia refrativa mais utilizada no mundo. Apesar de segura e efetiva, ela pode levar a algumas complicações. O crescimento epitelial pós-Lasik é uma complicação pós-operatória incomum, com prevalência maior em casos de retratamento. Geralmente, é um achado não...

Eye burns due to the accidental application of pharmacological or nonpharmacological substances packaged in plastic dropper bottles have been described for more than three decades and continue to occur. These burns can cause potentially serious corneal injuries. We report the case of a patient who mistak...
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...
Resumo Objetivo: Avaliar os resultados clínicos do Crosslinking Transepitelial (CXL) analisando sua eficácia em pacientes portadores de ceratocone progressivo. Métodos: Estudo transversal retrospectivo com 49 olhos e 37 pacientes com idades entre 10 e 50 anos, submetidos à técnica de CXL em 2017...

ABSTRACT The transparency and maintenance of corneal epithelial integrity are essential for its optical properties and, to preserve these characteristics, the epithelium undergoes continuous renewal. This renewal depends on the control of cell proliferation and differentiation mediated by mitogenic facto...
ABSTRACT Purpose: To evaluate the ability of human immature dental pulp stem cells, which are mesenchymal stem cells of neural crest origin, to differentiate into the corneal epithelium for purposes of corneal transplantation and tissue engineering when cultured on de-epithelized amniotic membranes. Me...

ABSTRACT Purpose: This study aimed to compare the effectiveness of eye drops containing a combination of sodium hyaluronate and trehalose and sodium hyaluronate for the treatment of corneal cross-linking and epithelial healing. Methods: This study included 46 eyes of 23 keratoconus patients who underwe...

ABSTRACT Purposes: To investigate the intra-laboratory reproducibility of clinical features and to evaluate corneal optical anisotropies in a rabbit model of limbal stem cell deficiency. Methods: Limbal injury was induced in the right eye of 23 adult New Zealand White rabbits using a highly aggressive ...
ABSTRACT Various approaches have been taken to improve our knowledge of the microenvironmental regulation of limbal epithelial stem cells. Researchers have extensively investigated the roles of growth factors, survival factors, cytokines, enzymes, and permeable molecules secreted by the limbal cells. How...
