Objective: To compare contrast sensitivity in different age groups: 20 to 25, 40 to 45 and above 60 years old. Methods: We performed a cross sectional study with individuals of different ages, with visual acuity better than 20/25, without eye disease and without prior eye surgery. Visual acuity was measured by Snellen test and contrast sensitivity was evaluated by OPTEC 3500P(r) equipment. Statistical analysis was performed using Wilcoxon test, considering a 95% confidence interval. Results: Compared to patients between 20 […]

Objective: Describe the epidemiological profile of cornea donors in the state of Goiás. Methods: We used a random sample of 793 records calculated by the formula of Leslie Kish (Epi Info 7) taking into account a total of 3,093 records from January 2006 to August 2015. The data was analyzed using the Statistical Package for Social Sciences (SPSS) and the results were described using proportions, central tendency and dispersion measures. Comparisons between categorical variables were made using the chi-square test […]

Objectives: Pre-anesthetic assessment (PAA) and laboratory tests are questioned for ophthalmic procedures due to their additional costs and surgery delays. These are lower risks, nonetheless, patients are elderly and suffer from multiple comorbidities. The aim of this study was to determinate if it is really necessary in a public hospital. Method: a retrospective study on 297 medical records containing the pre-anesthetic questionary from ophthalmic surgery patients in a public hospital was leaded. By the anamnesis, clinical examination and laboratory tests, […]

Purpose: To evaluate eye sensitivity disorder (similar to glare), with symptoms of visual fatigue, through watching television ULTRA HD3D-55-inch 4K curved screen among volunteers with normal eye examination. Methods: A prospective, longitudinal, case-control study, with inclusion and exclusion criteria and groups formation enrolled by age range. A comparison of a video documentary presented with the ULTRA HD TV 4K and with the FULL HD TV before and after the previous tele-audience, consisting of an evaluation of three phases of the […]

Objective: To determine the prevalence of low vision in a fraction of the students in public schools at Caratinga, Minas Gerais. Moreover, show the relevance of preventive measuresto evaluate Visual Acuity (VA) in children up to 7 years old. Methods: A transversal study was made in students, between 4 and 7 years old, enrolled in first and second year of elementary school of Geraldo Marques Cevidanes Municipal School, in the city of Caratinga, Minas Gerais.VA was evaluated using Snellen optometric […]

Objective: The objective of this study was to evaluate the efficacy of intravitreal triamcinolone and retrobulbar chlorpromazine as alternatives in the management of ocular pain in blind eyes. Methods: This was a non-randomized interventional prospective study of patients with painful blind eye unresponsive to topical treatment and without indication of evisceration treated at the Hospital Governador Celso Ramos Ophthalmology Service in 2010. After ocular examination and ocular B mode ultrasound, patients were divided into two groups. Group 1 patients had […]

Purpose: To determine the safety and efficacy of corneal collagen cross-linking (CXL) for progressive keratoconus in patients aged between 9 and 14 years old. Methods: Sixteen eyes of 11 patients (8 male and 3 female) with progressive keratoconus underwent epithelium-off CXL according to the standard Dresden protocol. Mean follow-up was 26 months (range, 12 to 60 months). Pre- and postoperative examinations included: uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), corneal topography, tonometry, refraction, corneal pachymetry, and endothelium cell […]

This article presents a review of the principles and clinical applications of the Scheimpflug principle in the anterior segment imaging. By providing a three-dimensional image of the anterior segment, this technology provides elevation and curvature data of the anterior and posterior surfaces of the cornea, pachymetric mapping, the total refractive power of the cornea and the anterior segment biometry. For the refractive surgery sub-specialty, this approach improves the ability to identify cases at risk of ectasia, as well as the […]
