ABSTRACT Objective To evaluate the preliminary medium-term results (up to 6 months) of the stand-alone use of XEN® Gel Stent implantation or in combination with cataract surgery in the Brazilian population. Methods A retrospective longitudinal study was carried out on eyes with primary open-angle glaucoma consecutively submitted to XEN® Gel Stent implantation surgery alone (XEN® Group) or in combination with cataract surgery (Phaco-XEN® Group) in the same center between April and December 2023. The ability to reduce intraocular pressure and […]

ABSTRACT This article is an update on the main concepts, techniques, equipment, lenses, and uses of the gonioscopy exam, with a main focus on its importance for new antiglaucoma therapies: selective laser trabeculoplasty and angular surgeries. This review and update is necessary because it is an essential exam for the daily practice of ophthalmologists, consolidating the knowledge necessary to perform it and because of the increasing use of gonioscopy in new anti-aglaucomatous therapies.

ABSTRACT Objective: To assess myopia prevalence in children from public schools of the metropolitan region of Porto Alegre, in Rio Grande do Sul. Methods: It is a prospective cross-sectional study with a sample of 330 children from public schools of the metropolitan region of Porto Alegre, from 5 to 20 years old. The students were submitted to an ophthalmological evaluation including auto-refractor measurements, best corrected and uncorrected visual acuity, subjective refraction under cycloplegia and axial length. The outcomes were prevalence […]

HISTORY Richard Banister (1622) was the first to associate the loss of vision by glaucoma with high levels of IOP.() Adolph Weber (1855) was the first to establish the concept of glaucoma as an optic neuropathy.() In 1864, eserine and physostigmine (miotics) were introduced as the first drugs extracted from a plant used to treat the progression of glaucoma.() It is well known that elevated or uncontrolled IOP cause the excavation of the optic disc (glaucomatous excavation) and visual field […]

ABSTRACT Retinitis pigmentosa is one of the leading causes of hereditary blindness in developed countries and unfortunately there is currently no cure. Photobiomodulation therapy can penetrate the retina and optic nerve and restore the function of damaged mitochondria as an intracellular target. This study is proposed to review and analyze photobiomodulation as a strategy that has the potential to be a new hope therapy and non-invasive treatment for retinitis pigmentosa in the long term. PubMed® and Google Scholar were used […]

ABSTRACT Maculopathy from prolonged exposure to solar light is a rare but well-recognized clinical entity of vision loss and macular damage. Photochemical damage precedes visual decline, and in mild cases, vision usually returns fully or partially. With the advancement of humanity, other forms of macular injuries induced by light radiation have emerged, increasing the group of photic maculopathies. In this report, we describe the cases of five patients where a diagnosis of photic maculopathy was made based on the anamnesis, […]

ABSTRACT Objective: To assess the performance of a portable autorefractor as refractor and screening tool for refractive errors in schoolchildren. Methods: Cross-sectional observational study. Refractometric measurements of children between 5 and 10 years old were obtained through four methods: 2WIN under non-cycloplegic conditions, and 2WIN, conventional autorefractor, and retinoscopy, under cycloplegic conditions. Correlations and agreement between the methods and accuracy of the portable autorefractor to define whether to prescribe glasses were assessed. Results: The mean age ± standard deviation was […]

ABSTRACT Objective: To describe the clinical features and outcomes of patients with uveitis associated with juvenile idiopathic arthritis (JIA) and idiopathic uveitis. Methods: This was an observational, retrospective study, conducted in a tertiary center. Patients under 18 years old who experienced at least one episode of uveitis and followed between 2000 and 2019 were included. Results: A total of 82 patients were included, of whom 43 had idiopathic uveitis and 39 had uveitis associated with JIA. Anterior uveitis was the […]
