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 […]

ABSTRACT Purpose To evaluate the efficacy of grafting a preseptal strip of orbicularis muscle to treat deep static glabellar wrinkles. Methods This was a prospective, interventional, case series study that included patients aged between 21 and 80, who underwent upper and lower blepharoplasty, and who presented varying degrees of deep static glabellar rhytids. After marking the glabellar rhytid, a subcision was made with 40 x 12mm needle along the entire length of the glabellar wrinkle. The orbicularis muscle graft was […]

ABSTRACT The aim of this study was to report a rare case of neovascular glaucoma in a patient with type 1 diabetes mellitus that progressed to necrotizing scleritis with inflammation. A 22-year-old male with poorly controlled type 1 diabetes mellitus experienced sudden painful vision loss on the right eye. Visual acuity on the right eye was no light perception, while it was 20/80 in the left eye. Intraocular pressure was measured at 35 mmHg, and the examination was consistent with […]

ABSTRACT A 41 year-old man presented with unilateral vision loss for a week and constitutional symptoms for 3 months. Ophthalmic evaluation revealed cotton wool spots on the right eye and widespread retinal necrosis and hemorrhage on the left eye, suggestive of cytomegalovirus uveitis and HIV infection and retinopathy, and confirmed by serology. The patient was treated with ganciclovir and highly active antiretroviral therapy and preserved contralateral vision. Clinicians should be aware of uveitis and retinopathies to prevent irreversible vision loss […]

ABSTRACT Introduction: Vision is one of the senses that most integrates the individual with the environment, since it captures most of the sensory stimuli to which the human being is exposed, and it is precisely this integration that allows the creation of memories and the formation of the knowledge. Low vision in childhood impairs learning, socialization, and also determines visual quality in adulthood. Objective: to identify the visual acuity of school children using the Snellen Test and refer and carry […]

ABSTRACT Objective: To assess the accuracy of general practitioners in recognizing diabetic retinopathy through color retinal retinography, with a two-hour training course, by comparing the capacity of screening and classifying diabetic retinopathy. Methods: In the first arm of the study, of 142 diabetic patients included, 274 eyes were evaluated, and these patients were examined with an indirect binocular ophthalmoscope and classified according to the degree of diabetic retinopathy. In the second arm of the study, 14 physicians who are not […]

ABSTRACT Objective: To analyze the morphological and functional long-term outcomes of amniotic membrane transplantation after ocular surface chemical burns. Methods: This prospective study analyzed 7 patients who suffered from severe ocular surface burn and underwent amniotic membrane transplantation from 2015 to 2020 in Hospital de Clínicas – Universidade Federal do Paraná. Results: Out of the seven patients, six (85.7%) suffered unilateral burn and one (14.3%) suffered bilateral burn. Five of them had alkali burns (71.4%), one had acid burn (14.3%) […]
