O Papel da Biomecânica Corneana como Preditor de Membranas Neovasculares Coroid...
Baptista, Pedro Manuel; Heitor Marques, João; Sousa, Paulo; Pires, Saul; Furtado, Maria João; Ribeiro Lume, Miguel; Meireles, Angelina; Ambrósio, RenatoINTRODUÇÃO: A maculopatia miópica na forma de neovascularização coroideia (mCNV) pode apresentar um impacto significativo na função visual, frequentemente em pacientes jovens ativos. O presente trabalho teve como objetivo descrever a biomecânica corneana em olhos míopes com histórico de mCNV tratados com anti-fator de crescimento endotelial vascular (VEGF) intravítreo e compará-la com os olhos contralaterais. O...
Myopia, Axial Length and Lens Thickness: A Corneal Biomechanical Analysis of Ol...
Ferreira, André; Marques, João Heitor; Marta, Ana; Castro, Catarina; Baptista, Pedro Manuel; José, Diana; Sousa, Paulo; Neves, Isabel; Menéres, PedroIntroduction: 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
Marques, João Heitor; Baptista, Pedro Manuel; Marta, Ana; Sousa, Paulo; Pires, Saul; Meireles, Angelina; Ambrósio, Renato; Menéres, PedroINTRODUCTION: 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
Castro, Catarina; Marques, Joao Heitor; Marta, Ana; Baptista, Pedro Manuel; José, Diana; Sousa, Paulo; Menéres, Pedro; Barbosa, IrenePurpose: 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...
Outcomes of Planed Intravitreal Therapy Interruption due to COVID-19 in Patient...
Castro, Catarina; Coelho, João; Correia, Nuno; Lume, Miguel; Menéres, Pedro; Pessoa, BernardeteINTRODUCTION: Our aim was to evaluate the outcomes of planed intravitreal injection (IVI) interruption in eyes with diabetic macular edema (DME) and the overall impact of COVID-19 in IVI. METHODS: Retrospective analysis of clinical data of eyes with DME undergoing treatment with IVI, that missed an IVI by their doctor’s decision (based on an implemented treatment guideline) due to COVID-19 pandemic, between 19 ...
Systemic and vitreous biomarkers : new insights in diabetic retinopathy
Pessoa, Bernardete; Heitor, João; Coelho, Constança; Leander, Magdalena; Menéres, Pedro; Figueira, João; Meireles, Angelina; Beirão, MeloPurpose: Diabetic retinopathy (DR) is a microvascular inflammatory and neurodegenerative disease. The purpose of this study was to analyze the relationship between DR severity and the levels of potential biomarkers in the serum and/or vitreous. Methods: A prospective, consecutive, controlled, observational study was performed between June 2018 and January 2020. Blood and vitreous samples were collected on the d...

Descrevemos um caso clínico documentado com fotografias em diferentes posições do olhar; gráficos do ecrã de Hess e testes de campo visual de Goldmann durente o período de seguimento. Relato de caso: Um homem de 42 anos envolveu-se num acidente de carro de alta energia (240 km/h). Nove dias depois, quando foi transfe...
Corneal Biomechanical Assessment with Ultra-High-Speed Scheimpflug Imaging Duri...
Baptista, Pedro Manuel; Ambrósio Jr, Renato; OLIVEIRA, LUIS; Menéres, Pedro; Beirão, JoãoBackground: In recent years, increasing interest has arisen in the application of data from corneal biomechanics in many areas of ophthalmology, particularly to assist in the detection of early corneal ectasia or ectasia susceptibility, to predict corneal response to surgical or therapeutic interventions and in glaucoma management. Technology has evolved and, recently, the Scheimpflug principle was associated w...
The Role of Corneal Biomechanics in the Assessment of Ectasia Susceptibility Be...
Baptista, Pedro Manuel; Marta, Ana; Marques, Joao Heitor; Abreu, Ana Carolina; Monteiro, Sílvia; Menéres, Pedro; Pinto, Maria do CéuPurpose: To describe the tomographic and corneal biomechanical status of a sample of eyes excluded from LVC and to present the differences in biomechanical behavior in relation to cutoffs of clinical- and tomography-based screening methods used in clinical practice. Patients and methods: Observational cross-sectional study including 61 eyes from 32 consecutive patients who were excluded from LVC in our departme...
