To analyze and compare corneal structural biomechanical properties, characterized by hysteresis (CH) resistance factor (CRF), between patients with without type 2 diabetes mellitus (DM), determine the main ocular variables that influence them. Sixty diabetic 48 age- sex-matched non-DM were enrolled in this cross-sectional study. The DM group was analyzed according to duration (<or ≥ 10 years), HbA1c levels 7%), presence of retinopathy. CH CRF evaluated using Ocular Response Analyzer® (ORA)....

Purpose . To compare intraocular pressure (IOP) and anterior segment (AS) morphometry changes after uneventful phacoemulsification between nonglaucomatous eyes with open-angles from patients without type 2 diabetes mellitus (DM) determine which factors may predict greater IOP-lowering effect. Methods Forty-five diabetic (45 eyes) 44 (44 age- sex-matched non-DM age-related cataract were enrolled in this prospective observational study. Goldmann applanation tonometry AS Scheimpflug tomography...

To compare corneal structure and endothelial morphological features between patients with type 2 diabetes mellitus (DM) non-diabetic patients; determine if the DM duration, glycated hemoglobin (HbA1c) levels, diabetic retinopathy (DR) stage affect properties.Sixty 47 age- sex-matched controls were enrolled in this cross-sectional study. group was analyzed according disease HbA1c presence of retinopathy. Endothelial cell density (ECD) morphology (average coefficient variation [CV] size,...

The aim of this study was to compare corneal structure and endothelial morphological changes after uneventful phacoemulsification cataract surgery between type 2 diabetic nondiabetic patients determine the preoperative intraoperative factors that may predict greater cell density loss.Forty-five pa-tients (45 eyes) 43 controls (43 with age-related were enrolled in prospective observational study. Corneal (thickness volume) anterior segment parameters measured by Scheimpflug tomography;...

&lt;b&gt;&lt;i&gt;Purpose:&lt;/i&gt;&lt;/b&gt; We investigated the characteristics, prognosis, and clinical outcome of Charles Bonnet syndrome (CBS) in patients with neovascular age-related macular degeneration (AMD). &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; Five hundred psychiatrically healthy AMD were screened for CBS. The individuals that fulfilled inclusion criteria systematically interviewed using a structured questionnaire covered impact, risk factors, phenomenology, symptoms,...

We investigate the prevalence of Charles Bonnet syndrome (CBS) in patients with neovascular age-related macular degeneration (AMD) and analyze role oral proton pump inhibitors (PPIs) other potential risk factors.A total 510 consecutive neovascular-AMD followed at a single tertiary center Portugal were screened for CBS. Using structured questionnaire, psychiatrically healthy individuals interviewed systematically divided into CBS group non-CBS group. Demographic data, current medication,...

Purpose . To evaluate the efficacy of “fogging test,” performed with a +2 diopters (D) lens, in exclusion clinically significant hyperopia school-aged children. Methods We studied 54 children between 5 and 11 years age, 10/10 best-corrected bilateral visual acuity (VA) without degree correction. VA was assessed each eye “bilateral” D sphere over-refraction followed by cycloplegic retinoscopy. The capacity test to detect ≥+2 ≥+1.5 evaluated examining respective receiver operating...

To evaluate inter-device agreement of anterior keratometry obtained by the IOLMaster® 500 and Pentacam® HR in type 2 diabetic non-diabetic patients.Corneal measurements were sequentially performed 60 diabetes mellitus (DM) 48 age sex-matched controls undergoing cataract surgery. Variables recorded included flat steep keratometry, mean (Km), astigmatism magnitude, axis location, J0 J45 components. Bland-Altman plots intraclass correlation coefficients used for examination agreement. Subgroup...

To describe the clinical, electrophysiological, and genetic findings of three Portuguese families with a rare variant in KCNV2 gene resulting "cone dystrophy supernormal rod responses" (CDSRR).Retrospective clinical revision five individuals from unrelated CDSRR. Ophthalmological examination was described all patients included color vision testing, fundus photography, autofluorescence (FAF) imaging, spectral domain-optical coherence tomography (SD-OCT), pattern electroretinogram (ERG),...

Background: Neurofibromatosis Type 1 (NF-1) is a genetic disease affecting the eye, and ocular findings such as Lisch nodules (LN) or optic pathway gliomas (OPGs) are part of its diagnostic criteria. Recent imaging technologies infrared (IR) optical coherence tomography (OCT) have highlighted visualization choroidal focal abnormalities in these patients, even absence other lesions. This study aimed to establish morphological multimodal evaluation patients with NF-1, correlating them central...

Purpose: To compare corneal biomechanical changes after uneventful phacoemulsification cataract surgery between type 2 diabetic (DM) and nondiabetic patients. Methods: Forty-four (44 eyes) 44 age sex-matched non-DM controls with age-related were enrolled in this prospective observational study. Corneal hysteresis (CH), resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc) evaluated by using the ocular response analyzer; central thickness was recorded Pentacam HR. Patients...

PURPOSE - To correlate the morphological characteristics of diabetic retinal microaneurysms on spectral domain optical coherence tomography (SD-OCT) with their functional leakage status fluorescein angiography (FA) in a simultaneous assessment.. METHODS – In this retrospective observational study, 88 11 eyes 6 type 2 adult patients retinopathy (DR) (8 moderate non proliferative DR and 3 DR) were analyzed FA SD-OCT imaging. Their SD-OCT, including shape, presence capsule-like structure,...

Purpose: We aim to report an atypical case of optic neuropathy associated with amiodarone a rapid development that presented unilateral disc edema and, consecutively, developed in the contralateral eye. Case report: An 80-year-old patient, taking for 2 months, progressive bilateral decrease visual acuity, more marked left eye (OS). The observation revealed acuity (VA) right (OD) 4/10, counting fingers OS, relative afferent pupillary defect, and papillary eye. In subsequent consultation, OD...

Abstract BackgroundDiabetic retinopathy (DR) and cataract are major complications that lead to significant visual impairment of diabetic patients. This study aims compare the changes in acuity, quality life satisfaction after phacoemulsification between type 2 nondiabetic patients.MethodsFifty-seven patients (37 with no [DR], 11 mild/moderate nonproliferative DR 9 severe nonproliferative/proliferative DR) 45 controls were submitted first-eye surgery by alone or co-adjuvant intravitreal...
