Avaliação Completa da Superfície Ocular num Coorte Pediátrico Português

INTRODUÇÃO: Existem poucos estudos publicados sobre doença do olho seco (DOS) no grupo etário pediátrico e os que existem foram realizados fora da Europa, onde os fatores genéticos e ambientais poderão ser diferentes. Além disso, o estudo da superfície ocular e, consequentemente, o diagnóstico da DOS cada vez mais tendem para métodos objetivos e padronizados. O objetivo primário desde trabalho foi de...

Myopia, Axial Length and Lens Thickness: A Corneal Biomechanical Analysis of Ol...

Introduction: Our objective was to compare the corneal biomechanics of myopes with non-myopes in a sample of Portuguese children. In addition, we sought to evaluate their habits and background as well as to assess the potential relationship of axial length and lens thickness with their corneal biomechanical properties.   Methods: Observational cross-sectional study assessing healthy children (8 to 18 years old)...

Biomechanical Predictors of Rhegmatogenous Retinal Detachment in Myopic Patients

INTRODUCTION: The prevalence of myopia is expected to increase significantly in the following decades. Moreover, axial myopia is associated with rhegmatogenous retinal detachment (RRD), a major cause of visual impairment in these patients. RRD develops after the dynamic interaction between the vitreous and the retina. Axial length (AL) is a well-described risk factor, but alone is insufficient to predict RRD. T...

Comparison of Light-Based Devices in the Treatment of Meibomian Gland Dysfunction

Purpose: To compare different light-based devices, namely, intense pulsed light (IPL) and IPL with low-level light therapy (LLLT), in the treatment of meibomian gland dysfunction (MGD). Methods: This was a prospective, observational study that included patients with MGD. Group 1 included 58 eyes treated with IPL (eye-light®, Espansione Marketing S.p.A., Bologna, Italy), followed by LLLT (my-mask®, Espansione Ma...

Propriedades Biomecânicas e Pressão Intraocular a Longo Prazo em Doentes com Qu...

INTRODUÇÃO: O nosso objectivo foi comparar as propriedades biomecânicas e a pressão intraocular a longo prazo entre olhos tratados com queratoplastia penetrante (PKP) e queratoplas- tia lamelar anterior profunda (DALK) em doentes com queratocone e doentes saudáveis. MÉTODOS: Estudo retrospetivo observacional caso-controlo com avaliação biomecânica da córnea por imagem de Scheimpflug de alta velocidade du...

Exuberant Choroidal Melanoma in COVID-19 Era

A 61-year-old man presented with a superior visu- al field defect on his right eye (RE), for 3 months, but he delayed coming to the emergency department for fear of coronavirus. His best-corrected visual acuity of the RE was 1.25/10 and biomicroscopy generated unremarkable findings. A large, dome-shaped, pigmented, and peripheral lesion with an adjacent exsudative retinal detachment was seen on ophthalmoscopy a...

Molecular and Multimodal Retinal Imaging Findings in a Multicentric Portuguese ...

Introduction Our purpose was to describe the molecular and multimodal retinal imaging findings in a cohort of Portuguese patients with a clinical diagnosis of Stargardt Disease (STGD1).   Methods Multicenter, cross sectional cohort study of consecutive patients with a clinical diagnosis of STGD1, referred from six Portuguese centers. All patients underwent a complete ophthalmological examination complemented by...

Changes in Corneal Biomechanical Properties after Artiflex® and Visian® ICLV4c ...

INTRODUCTION : Our purpose was to compare changes in biomechanical properties after Artiflex® and Visian® ICLV4c implantation. METHODS: A prospective, nonrandomized, comparative, interventional case series study with corneal biomechanical evaluation by an ultra-high-speed Scheimpflug imaging during non-contact tonometry (Corvis ST, OCULUS®). RESULTS: The study included 38 eyes: 23 Artiflex-treated eyes and 15 i...

Challenges, facilitators and barriers to the adoption and use of a web-based na...

Rare disease registries increase research accessibility for patients, while providing clinicians/investigators with a coherent data ecosystem necessary to boost research and patient care. The IRD-PT registry is a national, web-based, interoperable registry for inherited retinal degenerations (IRDs) designed to generate scientific knowledge and collect high-quality data on the epidemiology, genomic landscape and...
