OBJECTIVES: To describe and analyze the prevalence of refractive errors among first-graders in state schools of Passo Fundo, main city of the northeast region of Rio Grande do Sul State. METHODS: Cross-sectional study of 1608 first-graders in 26 elementary state schools of Passo Fundo, evaluated in 2004. The data were collected by the CEAE (Specialized Center for Student Assistance), which was in charge of the screening at the schools, and by the specialized service, to which those students with abnormal […]

PURPOSE: To compare measurements of central corneal thickness obtained using a Haag-Streit optic pachymeter and a DGH 500 (Pachette Ttm ) ultrasonic pachymeter in normal patients. METHODS: An evaluation was made of 200 eyes of 100 patients using Optic (PO) and Ultrasonic (PU) pachymeters. Measurements were made in the area of the central cornea (ECC) respecting the 3.0 mm territory, in patients with normal corneas of hypermetropic, emetropic and myopic eyes. Patients with ocular diseases, ocular surgeries, and contact lens […]

PURPOSE:To identify the most important variables interfering with the correct topical administration of antiglaucomatous drugs. METHODS: Forty glaucomatous patients under clinical treatment were interviewed and observed while applying antiglaucomatous drugs. The following variables were analyzed: sex; age; income; washing of the hands; number of drops; motor abnormalities; availability of another person to apply the drug; place of the globe reached; bottle-eye contact; previous instruction; positioning for application; development of a burning sensation, pain or irritation. Using the questionary, the variables […]

PURPOSE: To estabilish the prevalence of the ametropias and eye diseases, in the year 2001, within a preschool and school population in Alto da Boa Vista favelas (slum), in the city of Rio de Janeiro, Brazil. METHODS: Transversal observational study during an ocular health campaign in public education schools. The children that have shown visual acuity fewer than 0.8 or abnormally were referred by trained volunteers to avaliation by ophthalmologists from the Benjamin Constant Institute. RESULTS: From the 1800 children […]

PURPOSE: To present biometric predictability, evaluating postoperative refraction and visual acuity in eyes submitted to multifocal intraocular lens implantation. METHODS: Retrospective study in 88 eyes of 50 patients, submitted to phacoemulsification with multifocal lens implant of three commercial brands: ReSTOR, ReZoom and Tecnis. For biometric examination were used: optic biometry associated to the use of tomography of anterior segment and Holladay II biometric formula. With postoperative refraction, visual acuity and implanted IOL, according to Holladay II formula, we calculated the […]

PURPOSE: To estimate if a complicated phacoemulsification is a risk factor for developing age related macular degeneration. METHODS: Retrospective case-control study with review of records of 1150 patients, that underwent phacoemulsification surgery between 1995 and 1999, performed by a single surgeon (T.C.) Qui square test, Fisher exact test, and Mann-Whitney test were used to perform statistical analysis. RESULTS: There were 224 participants who had cataract surgery on 297 eyes, and from this total, 240 were with no complication and 57 […]

OBJECTIVE: To determine if the AutoCAD 2004 program is available to be used in quantitative research on electron microscopy. METHODS: A demonstrative of the AutoCAD2004 was done in an experimental model of diabetes induced in rats. The animals were divided by lot in control group animals (GC-10 animals) and diabetic group (GD – 10 animals), evaluated 1 month after the diabetes induction. The eyes were removed after sacrifice and prepared to electron microscopy. The retina was photographed and the AutoCAD2004 […]

OBJECTIVE: To analyse the main ocular presentations observed in leprosy diagnosed patients in Northern and Southeastern in Brasil regions. METHODS: Twenty-eight diagnosed leprosy patients were examined divided in two groups. Group I, compound by 12 patients at southeastern (ABC) and group II, compound by 16 patients at northern region (Amazon). Group I was examined from August 2003 to June 2004 at SP, in FMABC ophthalmology outpatient service and the second group was examined during the10th Mission of 2000 Vision Amazon […]
