ABSTRACT Dry eye disease comprises a spectrum of disorders that cause unstable tear film with an irregular surface. Preexisting dry eye disease poses challenges during cataract surgery in chronic inflammation since preoperative biometry measurements are highly dependent on a smooth and healthy tear film. Following the recent approval by the Conselho Federal de Medicina, lens replacement procedures have become legal in Brazil and are indicated for patients over 55 years of age who have presbyopia with moderate or high hyperopia.

ABSTRACT Glaucoma is considered the biggest cause of irreversible blindness in the world and the increase in intraocular pressure is its main risk factor. Usually, the initial therapy for glaucoma consists of reducing IOP through the instillation of topical hypotensive drugs, with antiglaucoma surgeries being normally reserved for cases in which disease control is not clinically achieved. Classically, the surgical treatment of glaucoma is performed using filtering procedures: trabeculectomy; non-penetrating sclerotomy and glaucoma drainage devices. The acronym MIGS (Minimally Invasive […]

ABSTRACT Silicone oil has been an important intraocular tamponade in retinopexy in cases of complicated retinal detachment surgery. The increase of intraocular pressure and development of secondary glaucoma are a known complication of its use. A variety of mechanisms have been proposed for the pathogenesis, depending on the onset. This article aims to review the literature about pathogenesis, the incidence and risk factors, as well as the treatment of this pathology.

ABSTRACT Optical coherence tomography is often used for detection of glaucoma as well as to monitor progression. This paper reviews the most common types of artifacts on the optical coherence tomography report that may be confused with glaucomatous damage. We mainly focus on anatomy-related artifacts in which the retinal layer segmentation and thickness measurements are correct. In such cases, the probability maps (also known as deviation maps) show abnormal (red and yellow) regions, which may mislead the clinician to assume […]

ABSTRACT The rate of visual field progression is an essential factor in determining risk of visual disability or blindness in glaucoma patients. Knowledge of the rate of progression of a particular patient, in combination with an estimation of their longevity and other clinical factors, allows clinicians to optimize management by providing appropriately aggressive treatment. Despite decades of research on the treatment of glaucoma, the natural history of glaucomatous visual field progression in untreated and treated patients remains unclear. The purpose […]

ABSTRACT It is part of the omic sciences to search for an understanding of how the cellular system of organisms works as well as studying their biological changes. As part of the omic sciences, we can highlight the genomics whose function is the study of genes, the transcriptomics that studies the changes in the transcripts, the proteomics responsible for understanding the changes that occur in proteins, and the metabolomics that studies all the metabolic changes that occur in a certain […]

ABSTRACT Glaucoma drainage devices are important therapeutic options for cases of refractory glaucoma, in which trabeculectomy with antimetabolites has shown high risk of failure. There are devices with different sizes, designs and materials, and several studies have been conducted to test their safety and effectiveness. Despite known complications, their use has progressively increased in recent years, and they are the primary surgical option, in some situations. The aim of this review is to discuss the importance, mechanisms, biomaterials, results and […]

ABSTRACT The purpose of this study was to highlight the impact of biomechanical corneal response in available in vivo tonometry methods for glaucoma management. Systematic review of non-contact air-puff tonometers that analyzes the corneal deformation response, with special focus on the investigation of the correlation of derived parameters with intraocular pressure measurements. The two actual and commercially available in vivo corneal tonometers provide promising information about biomechanical characteristics of the cornea and its relation to glaucoma, allowing the development of […]
