Purpose: to evaluate the use of air tonometer (TA) in population studies in individuals suspected of ocular hypertension, comparing values with those provided by the Goldmann Tonometer (GT). Methods: a cross-sectional study was done using a probabilistic sample consisting of 11,452 individuals e”20 years old.A subsample composed by the individuals with IOP values obtained with TA e”20 mmHg was selected, in which IOP was repeated with the GT. The results of both tonometers were compared considering gender, referred color of […]

Objective: The aim of this study was to evaluate the biocompatibility of Nanoskin for replacing volume in enucleated or eviscerated anophthalmic sockets of rabbits. Methods: An experimental study was carried out using enucleated or eviscerated rabbits, which received Nanoskin implants (Innovatecs®, São Carlos, Brazil), a cellulose produced by a bacteria (Acetobacter xylinum) using green tea as substrate. Implants of 10mm diameter/5mm of thickness were used placed in enucleated (G1) or eviscerated (G2) anophthalmic sockets of 21 rabbits.They were clinically examined […]

Objetivo: Durante quase um século, a ceratoplastia penetrante tem sido a técnica cirúrgica de escolha no tratamento de doenças corneais. No entanto, nos últimos anos, têm sido desenvolvidas várias técnicas de transplante lamelar, especialmente modificadas ou aperfeiçoadas para substituir a porção posterior para a correção da ceratopatia bolhosa. O objetivo deste estudo foi avaliar a eficácia e segurança da ceratoplastia endotelial quando comparada a ceratoplastia penetrante para a ceratopatia bolhosa afácica ou pseudofácica. Métodos: Uma revisão sistemática da literatura foi […]

Objective: For nearly a century, penetrating keratoplasty has been the surgical technique of choice in the management of corneal changes. However, in recent years, several lamellar keratoplasty techniques have been developed, modified or improved, especially techniques for replacing the posterior portion, for the correction of bullous keratopathy. The aim of this study was to evaluate the effectiveness and safety of endothelial keratoplasty versus penetrating keratoplasty for pseudophakic and aphakic bullous keratopathy. Methods: A systematic review of the literature was carried […]

Objective: To evaluate the occurrence of a mutation in candidate genetic loci and its relation with keratoconus in patients treated in Brazil compared to healthy volunteers, through analysis of single nucleotide polymorphism in the DOCK9 gene. Methods: In this clinical study, 108 participants were evaluated, including 46 keratoconus patients and 62 healthy volunteers (controls). DNA samples were extracted from collected blood from keratoconus patients and controls. The genotyping of the single nucleotide polymorphism rs7995432 in the DOCK9 gene was determined […]

Endogenous endophthalmitis is a rare, and frequently devastating, ophthalmic disease. It occurs mostly in immunocompromised patients, or those with diabetes mellitus, cancer or intravenous drugs users. Candida infection is the most common cause of endogenous endophthalmitis. Ocular candidiasis develops within days to weeks of fungemia. The association of treatment for pancreatitis with endophthalmitis is unusual. Treatment with broad-spectrum antibiotics and total parenteral nutrition may explain endogenous endophthalmitis. We report the case of a patient with pancreatitis treated with broad-spectrum antibiotics […]

Endoftalmite endógena é uma condição oftalmológica rara e frequentemente devastadora. Ocorre principalmente em pacientes imunocomprometidos, diabéticos, com neoplasias ou usuários de drogas intravenosas. Infecção por Candida é a causa mais comum de endoftalmite endógena. A candidíase ocular ocorre de dias a semanas após a fungemia. A associação de endoftalmite e o tratamento para pancreatite é rara. O tratamento com antibióticos de amplo espectro e alimentação parenteral total podem explicar uma endoftalmite endógena. Neste estudo, reportamos o caso de um paciente […]

The authors report the first case in Brazilian literature of orbital apocrine hidrocystoma with immunohistochemistry confirmation. The tumor had been growing slowly and progressively, there was no history of impaired vision, diplopia, watering, discharge, or prior trauma. There was no proptosis and extraocular mobility was normal. The radiologic study by orbital computerized tomography revealed an extraconal nodule, with partially defined limits, with cystic and solid areas in the superomedial right orbit. An anterior orbitotomy, with full excision of the tumor […]
