ABSTRACT This study aimed to critically review the literature regarding the magnitude, orientation, and correlation between anterior, posterior, and total corneal astigmatism, as well as their clinical implications in normal eyes, in patients with keratoconus, and in individuals evaluated in the context of refractive surgery. An integrative literature review was conducted, with a systematic search of studies published between 2010 and 2025. Observational studies that assessed corneal astigmatism using Scheimpflug tomography in healthy eyes, eyes with keratoconus, or eyes evaluated […]

ABSTRACT Objective: To identify if there is a significant change on refraction after Nd:YAG laser posterior capsulotomy in pseudophakic eyes. Methods: A retrospective study with analysis of medical records of patients treated at a hospital, with diagnosis of opacification of posterior lens capsule treated with Nd:YAG laser posterior capsulotomy, from October 2019 to March 2021. The comparison of refraction before and after the procedure was performed by calculating the spherical equivalent. Changes in visual acuity (VA), measured by LogMAR, were […]

Purpose: To determine the prevalence of predisposing factors of low visual acuity among the students of the Geraldo Reis University College in Niterói-RJ. Methods: This was a cross-sectional observational study during which the visual acuity of the volunteer students who adhered to the assent term was measured. Those students whose visual acuity did not exceed 0.8 in at least one eye or who presented a difference between the eyes of two lines or more in the Snellen table were selected […]

Objective: Therapeutic evaluation of Bevacizumab application in relapsed pterygium concerning visual acuity, keratometry, refraction, symptomatology. Methods: Group 1 (4 patients) received 0.1 ml of Bevacizumab (avastin), being evaluated posteriorly on the tenth and thirtieth days after the application, seeking to compare with the exam previously made, being it realized with the other two groups, in which Group 2 (4 patients) received 0.2 ml of Bevacizumab and the Group 3 (3 patients) received 1 ml of the placebo injection. Results: In […]

Objetivo: Avaliação terapêutica da aplicação de bevacizumabe em pterígio recidivado com relação a acuidade visual, ceratometria, refração, sintomatologia. Métodos: O Grupo 1 (4 pacientes) recebeu 0,1ml de bevacizumabe (avastin) sendo avaliado posteriormente, nos dias 10 e 30 após a aplicação, buscando-se comparar com o exame previamente realizado, sendo o mesmo realizado com os outros dois grupos, em que o Grupo 2 (04 pacientes) recebeu 0,2ml de bevacizumabe e o grupo 3 (3 pacientes) recebeu 0,1 de injeção placebo. Resultados: Neste […]

Objective: The aim of this study is to examine the effect of Nd: YAG laser capsulotomy on refraction, central macular thickness (CMT) and retinal nerve fiber layer (RNFL) thickness. Methods: 42 eyes of 42 patients who treated with Nd:YAG laser capsulotomy were included in thisprospective study. Spherical equivalent (SE), cyclindrical power refraction, CMT and RNFL thickness were evaluated preoperatively and at postoperative first day, first week and postoperative first month. Results: Spherical equivalent values and central macular thickness values did […]

Objetivo: O objetivo deste estudo é examinar o efeito da capsulotomia de laser Nd: YAG na refração, espessura macular central (CMT) e espessura da camada de fibra nervosa retiniana (RNFL). Métodos: 42 olhos de 42 pacientes que trataram com capsulotomia laser Nd: YAG foram incluídos neste estudo prospectivo. O equivalente esférico (SE), a refração de potência cíclica, a espessura CMT e RNFL foram avaliados pré-operatório e no primeiro dia pós-operatório, primeira semana e primeiro mês pós-operatório. Resultados: valores equivalentes esféricos […]

Objective: Measure the “Projeto Olhar Brasil” under a critic point of view, examining the prevalence of patients referred for ophthalmological appointment, post-screening, that show refractive errors uncorrected. Methods: Review of records between March 2014 and August 2016, in totality of 339 patients between 6 and 18 years old, 5 preschools (2 – 6 years and 11 months) 124 school (7 – 9 years and 11 months) and 210 teenagers (10 – 20 years old). There were 156 males and 183 […]
