Introduction Upper tarsal mechanical forces influence corneal epithelial thickness profile, which could modulate corneal astigmatism. Upper eyelid blepharoplasty reduces upper tarsal strength and may have an impact on ocular surface. The aim of this study is to evaluate the effect of upper eyelid blepharoplasty on corneal epithelial thickness profi...

Introduction: Strabismus is a common condition among children, and its psychosocial impact has been demonstrated in recent years. The interest in a more comprehensive approach was enhanced by the recognition of health as a four-dimensional concept, arising the term Health-related Quality of Life. Therefore, we aim to evaluate the influence of strab...

Purpose To evaluate the changes on epithelial thickness before and after topical treatment in primary Sjögren syndrome-associated dry eye disease (SS-DED).

Methods Twelve patients underwent bilateral LuxSmart IOL implantation, and twelve...

Background: To evaluate retinal morphological and vascular parameters in patients recently diagnosed with obstructive sleep apnea syndrome (OSAS) and determine the correlation between retinal vascular density and the severity of OSAS. Methods: We performed a retrospective study on the retinal vasculature of patients with OSAS and age-match healt...

Purpose: Our aim was to assess ocular surface and tear film stability and corneal epithelial thickness (CET) in patients with Graves disease (GD) with and without Graves orbitopathy (GO). Methods: This study included healthy age-matched controls and patients with GD. Symptoms (Ocular Surface Disease Index questionnaire) and signs (schirmer test...

Cyclosporine A (CsA) is an immunomodulatory agent that has a selective inhibitory action on T-cell lymphocytes. Topical CsA with various formulations has been used in ophthalmology. This article aims to present a review of the published scientific literature reviewed by peers and to illustrate some applications of CsA in the areas of ocular surface...

Introduction and Objective To evaluate corneal epithelial thickness (ET) and corneal thickness (CT) profiles in healthy eyes of Portuguese children and provide information to establish the first normative Caucasian database for these age group. Methods Sixty healthy eyes of 60 children aged between 8 and 18 were evaluated using the Cirrus high-def...

Purpose To assess the clinical outcomes and patient satisfaction of the Tecnis Eyhance, an advanced monofocal intraocular lens (IOL), compared to a conventional monofocal IOL. Design Retrospective case-control study. Methods This study included 120 eyes of 60 patients (30 patients in each group) who underwent bilateral cataract surgery either wit...

Purpose The aim of this study was to compare the results of intrastromal arcuate incisions (AIs) and transepithelial AIs to treat corneal astigmatism during femtosecond laser-assisted cataract surgery (FLACS). Methods This retrospective study included 20 patients with corneal astigmatism between 0.70 and 2.00 diopters (D) who underwent FLACS with...

Background/objectives Continuous subcutaneous insulin infusion (CSII) is a treatment for type 1 diabetes that improves metabolic control and reduces micro and macrovascular complications. The aim of this study was to compare the effect of CSII versus traditional multiple daily injections (MDI) therapy on retinal vasculature. Methods We performed a...

Resumen Objetivo El objetivo del estudio fue comparar los resultados de las incisiones arcuatas (IA) intraestromales y transepiteliales para tratar el astigmatismo corneal en el momento de la cirugía de catarata asistida con láser de femtosegundo (FLACS). Método Este estudio retrospectivo incluyó 20 pacientes con astigmatismo corneal entre 0,70 y...

Purpose Conjunctival Squamous cell carcinoma (SCC) represents a malignant disease that, if untreated, can cause irreversible loss of vision or even death. It is a rare disease, which is why the diagnostic and therapeutic approaches are not always linear. To report a case of a giant conjunctival SCC, including its diagnostic and therapeutic approach...

Purpose To assess the clinical status of corneal ectasia, including clinical outcomes and tomographic/biomechanical assessments of asymmetric keratoconus patients who had surgical treatment only in the most advanced eye. Methods This retrospective study included 100 eyes of 50 asymmetric keratoconus patients who had surgery in one eye. The eyes we...

The purpose of the study is to present a case of indirect carotid cavernous fistula (CCF) successfully treated with endovascular approach. A 46-year-old male presented with a progressive, painless visual loss and conjunctival injection of the right eye with 1 month of evolution. On ophthalmology examination, the patient had best-corrected visual ac...

Purpose: To test the accuracy of the Tomographic and Biomechanical Index (TBI) for ectasia detection in an independent population from the original study. Design: Retrospective observational case-control study. Subjects: Patients were grouped according to clinical diagnosis including corneal topography (front-surface curvature). Methods: Nor...
