Retinal Structural Changes in Preterm Children without Retinopathy of Prematurity
Maleita, D; Serras-Pereira, R; Passos, I; Elisa-Luís, M; Alves, M; Papoila, AL; Brito, C; Cunha, JP; Tavares Ferreira, JPurpose: The aim of this study was to compare all retinal layers' thickness in full-term and preterm children without retinopathy of prematurity (ROP). Methods: Cross-sectional study including two groups of patients: group 1 children with history of preterm gestation without ROP (gestational age < 37 weeks) and group 2 healthy children with history of full-term gestation. All subjects underwent an ophthalmic ex...
Optic Neuropathy Due to Chronic Lymphocytic Leukemia: the First Manifestation o...
Maleita, D; Serras Pereira, R; Hipólito-Fernandes, D; Moura-Coelho, N; Cunha, JP; Tavares Ferreira, JPurpose: Chronic lymphocytic leukemia (CLL) is the most common lymphoproliferative disorder in the western world. The involvement of the central nervous system (CNS) or the optic nerve in CLL, however, is rare. We report a case of a previously untreated patient with CLL whose first manifestation of the disease was a progressive visual loss caused by optic neuropathy. Observations: Clinical manifestations, optic...
Ocular Ischaemia Due to a Spontaneous Carotid Artery Dissection
Frazão, S; Perry da Câmara, C; Proença, R; Tavares Ferreira, JInternal carotid artery dissection (ICAD) is caused by the disruption of the tunica intima, with the formation of an intramural haematoma that can cause stenosis or occlusion of the artery's lumen, leading to reduced blood flow and secondary thrombus formation. Up to two-thirds of patients with ICAD show ophthalmological symptoms or signs, which are, frequently, the first manifestations of this clinical conditi...
The Role of Ophthalmic Imaging in Central Nervous System Degeneration in System...
Dias-Santos, A; Proença, R; Tavares Ferreira, J; Pinheiro, S; Cunha, JP; Proença, R; Moraes-Fontes, MFSystemic lupus erythematosus (SLE) is an autoimmune connective tissue disorder that can involve any organ system. Central nervous system involvement can be a severe life threatening complication, ultimately resulting in severe neurodegenerative changes. Magnetic resonance imaging suggests that neurodegeneration, which may have deleterious effects on brain function, may occur early in SLE and experimental models...
Retinal Neurodegeneration in Diabetic Patients Without Diabetic Retinopathy
Tavares Ferreira, J; Alves, M; Dias-Santos, A; Costa, L; Santos, B; Cunha, JP; Papoila, AL; Abegão Pinto, LPURPOSE: To compare the thickness of all retinal layers between a nondiabetic group and diabetic patients without diabetic retinopathy (DR). METHODS: Cross-sectional study, in which all subjects underwent an ophthalmic examination including optical coherence tomography. After automatic retinal segmentation, each retinal layer thickness (eight separate layers and overall thickness) was calculated in all nine Ear...
