ABSTRACT Objective: The primary objective of this study was to characterize normal optic nerve parameters in Latin American patients using Optical Coherence Tomography (OCT) during the period from 2015 to 2022. Methods: A retrospective, cross-sectional, descriptive study was conducted using data retrieved from the database of the Exilaser Clinic in Cuenca, Ecuador. The study included 290 adult patients without ocular abnormalities. Data from each eye (left and right) were analyzed using SPSS software. For quantitative variables, measures of central tendency […]

ABSTRACT Objective: Early and accurate detection of corneal ectasias is essential for appropriate clinical management. The combined use of Pentacam and anterior segment OCT allows for a more comprehensive assessment of the morphological abnormalities associated with corneal ectasias, enabling earlier differentiation between normal and suspect cases. This study aims to investigate the relationship between OCT and Pentacam findings in the detection of corneal ectasias, analyzing their interdependence and clinical relevance. Methods: An analytical cross-sectional observational study based on data collected […]

ABSTRACT The characteristic optical coherence tomography finding in solar maculopathy is a well-defined outer retinal hyporeflective space primarily involving the photoreceptor inner and outer segment layers. This typical optical coherence tomography image may be present in a few other pathologies, which currently constitute their main differential diagnoses. Our study shows the report of 12 eyes of 6 patients treated at the Hospital de Olhos do Paraná, presenting their clinical history and diagnostic images, with the purpose of comparing the findings […]

ABSTRACT We report a case of two twins for whom advanced keratoconus is present in one of the siblings and no clear sign of the disease could be found for the other.

Abstract Objective: To Perform a review on the diagnosis of keratoconus, focusing on the available propaedeutic methods. Methods: A search was performed in the PubMed database using the key words: Keratoconus, diagnosis, topography and tomography. As it is a review, there was no restriction regarding the publication period of the selected articles. Furthermore, both the preferred practice pattern(PPP) manual of the American Academy of Ophthalmology, as well as the website “eyewiki.aao.org” were used as reference. The project was submitted to […]

Objetivos: Comparar o efeito do ranibizumabe intravítreo (0,3mg) e triacmicinolona (4mg) em diferentes parâmetros do domínio espectral da OCT e sua relação com a acuidade visual de pacientes com edema macular diabético. Métodos: Este estudo foi concebido como um estudo prospectivo randomizado. Os pacientes foram divididos aleatoriamente em 2 grupos que receberam Ranibizumab Pro rata intravitreal (0,3mg) ou acetonido de Triamicinolona (4mg), a quem foi realizada a Spectral Domain OCT, bem como a melhor acuidade visual de Log MAR corrigida. […]

Objective: Analyze clinical data, therapy and tomographic parameters of patients attended at Fundação Hilton Rocha. Methods: This essay is a retrospective study based on a random sample of 150 patients submitted to cornea tomography and previous segment (Pentacam – Oculus, Wetzlar, Germany) at Fundação Hilton Rocha in the year 2015. The patients were classified as carriers or suspects of keratoconus through the following parameters: pachymetry, anterior and posterior central elevation, Ambrosio Relational Thinnest (ART), value of D and keratometry. After […]

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 […]
