Outcomes of Cystoid Macular Edema Following Descemet's Membrane Endothelial Ker...
Moura-Coelho, N; Papa-Vettorazz, R; Santiesteban-García, I; Dias-Santos, A; Manero, F; Cunha, JP; Güell, JThe aim of this study was to analyze the outcomes of eyes with visually significant cystoid macular œdema (vs-CMO) after Descemet membrane endothelial keratoplasty (DMEK) in a referral center for keratoplasty in Spain. We conducted a retrospective, single-surgeon case series of eyes that developed post-DMEK vs-CMO performed between January 2011 and December 2020. Data collected included: indication for DMEK; bi...
Ocular Involvement in Systemic Lupus Erythematosus Patients: a Paradigm Shift B...
Dias-Santos, A; Ferreira, J; Pinheiro, S; Cunha, JP; Alves, M; Papoila, AL; Moraes-Fontes, MF; Proença, RObjective: To evaluate ocular involvement in a cohort of systemic lupus erythematosus (SLE) patients of a tertiary referral center and to compare the results with the existing literature. Methods: Patients underwent a complete ophthalmological evaluation, including visual acuity, slit-lamp examination, fluorescein staining, Schirmer-I test, Goldmann applanation tonometry, fundoscopy, 10-2 automated threshold vi...
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...
Retina and Choroid of Diabetic Patients Without Observed Retinal Vascular Chang...
Ferreira, J; Proença, R; Alves, M; Dias-Santos, A; Santos, B; Cunha, JP; Papoila, AL; Abegão Pinto, LPURPOSE: To identify changes in choroidal thickness (CT) and all retinal layers of diabetic patients without diabetic retinopathy (DR) after 1 year of follow-up. DESIGN: Prospective observational cohort study. METHODS: Overall, 125 diabetic patients without DR were included. Two visits were scheduled: the first visit (V1) and a second visit after 12 months (V2). At both visits, patients received a complete opht...
Choroidal Thinning: Alzheimer's Disease and Aging
Cunha, JP; Proença, R; Dias-Santos, A; Melancia, D; Almeida, R; Águas, H; Oliveira Santos, B; Alves, M; Ferreira, J; Papoila, AL; Louro, CINTRODUCTION: The purpose of this study was to measure and to compare macular choroidal thickness (CT) between patients with mild Alzheimer's disease (AD), patients without AD, and elderly patients. METHODS: CT was measured manually in 13 locations at 500-μm intervals of a horizontal and a vertical section from the fovea. Linear regression models were used to analyze the data. RESULTS: Fifty patients with a dia...
OCT in Alzheimer's Disease: Thinning of the RNFL and Superior Hemiretina
Cunha, JP; Proença, R; Dias-Santos, A; Almeida, R; Águas, H; Alves, M; Papoila, AL; Louro, C; Castanheira-Dinis, ABACKGROUND: Peripapillary retinal nerve fiber layer (pRNFL) and internal macular layer thinning have been demonstrated in Alzheimer's disease (AD) with optical coherence tomography (OCT) studies. The purpose of this study is to compare the pRNFL thickness and overall retinal thickness (RT) in AD patients with non-AD patients, using spectral domain optical coherence tomography (SD-OCT) and determine the sectors ...
Alzheimer's Disease: a Review of its Visual System Neuropathology. Optical Cohe...
Cunha, JP; Moura-Coelho, N; Proença, R; Dias-Santos, A; Ferreira, J; Louro, C; Castanheira-Dinis, AAlzheimer's disease (AD) is a prevalent, long-term progressive degenerative disorder with great social impact. It is currently thought that, in addition to neurodegeneration, vascular changes also play a role in the pathophysiology of the disease. Visual symptoms are frequent and are an early clinical manifestation; a number of psychophysiologic changes occur in visual function, including visual field defects, ...
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...
Phacoemulsification Versus Peripheral Iridotomy in the Management of Chronic Pr...
Dias-Santos, A; Ferreira, J; Abegão Pinto, L; Domingues, I; Silva, JP; Cunha, JP; Reina, MPrimary angle closure occurs as a result of crowded anterior segment anatomy, causing appositional contact between the peripheral iris and trabecular meshwork, thereby obstructing aqueous outflow. Several studies highlight the role of the crystalline lens in its pathogenesis. The objective of this work is to compare the long-term efficacy of phacoemulsification versus laser peripheral iridotomy (LPI) in the man...
The Impact of Multifocal Intraocular Lens in Retinal Imaging with Optical Coher...
Dias-Santos, A; Costa, L; Lemos, V; Anjos, R; Vicente, A; Ferreira, J; Cunha, JPMultifocal intraocular lenses (MF IOLs) have concentric optical zones with different dioptric power, enabling patients to have good visual acuity at multiple focal points. However, several optical limitations have been attributed to this particular design. The purpose of this study is to access the effect of MF IOLs design on the accuracy of retinal optical coherence tomography (OCT). Cross-sectional study cond...
