OBJETIVO: Avaliar o efeito da thalamosinusotomia ab interno, que é um procedimento cirúrgico experimental similar a esclerotalamotomia ab interno, na drenagem do humor aquoso. MÉTODOS: Olhos de porco enucleados foram perfundidos com solução fisiológica de Krebs-Ringer e azul de tripan, sob diferentes pressões constantes de perfusão, após o procedimento cirúrgico experimental. A facilidade de drenagem e os tecidos corados/não corados foram medidos. RESULTADOS: A facilidade de drenagem e a área sob a curva (fluxo) aumentaram com o aumento do número […]

PURPOSE: To report the profile of Coats’ disease patients, referred to exclude retinoblastoma. METHODS: Retrospective study of medical charts from ten consecutive patients. Data evaluated include age at diagnosis, gender, chief complain, disease stage, treatment and evolution. RESULTS: Mean age at diagnosis was 43.9 months. Eight patients had stage 3B of the disease, one stage 3A and one 2B. From the eight patients with total retinal detachment (3B disease), seven were managed by observation one was submitted to unsuccessful retinopexy. […]

PURPOSE: Could the central corneal thickness (CCT) change the intraocular pressure (IOP) measured by ICARE (IC) GOLDMANN APPLANATION TONOMETER (GAT) and PASCAL DYNAMIC COUNTOUR TONOMETER (PDCT). METHODS: Before using the anesthesia we have measured the IOP with IC tonometer. After that we have used topical anesthesia to obtain the CCT using an ultrasound pachymeter (Mentor Co.) and the IOP measured by PCDT followed by a drop of fluorescein to measured IOP with GAT. RESULTS: 138 eyes of 71 patients were […]

PURPOSES:This study focuses the orbital exams of ultrassononography (US), computed tomography (CT) and magnetic resonance imaging (MRI), and has the following purposes: Collecting the paid amounts by Sistema Único de Saúde (SUS), Associação Médica Brasileira (AMB) and private clinic tables. Reviewing the advantages and disadvantages of the referred diagnostic tests. Suggesting administrative efficiency measures related to these tests in the orbit. METHODS: The costs were achieved based on the amounts paid by SUS, brazilian medical insurance companies and private clinics […]

OBJECTIVE: To show visual and refraction results using multifocal diffractive apodized intraocular lens. METHODS: The study of 100 eyes of 50 patients with cataract, submitted to phacoemulsification with bilateral implant of multifocal diffractive apodized intraocular lens (IOL). Binocular visual acuity was evaluated with and without correction for near and distance, and refraction previsibility and frequency of wearing glasses. RESULTS: Visual acuity without correction for distance was e” 20/30 in 97.56% of eyes operated on and e” J2 in 100%, of […]

PURPOSE: to determine the prevalence of astigmatism and the change of the axis according to the age in an ophthalmology private clinic population in the city of Florianópolis, Santa Catarina, Brazil. METHODS: A retrospective, descriptive, cross-sectional study was carried out based on the analyses of medical files. Astigmatism was classified as a cylindrical equivalent <-0,5 diopter (D). Astigmatism with the rule was defined as 160° to 20° , oblique astigmatism as 21° to 69° and 111° to 159° , and […]

PURPOSE: To assess the efficacy of topical cyclosporine .05% for preventing endothelial loss in cornea transplant. METHODS: Retrospective study of 18 eyes submitted to penetrating transplant due to keratoconus, operation carried out by the same surgeon. Patients with specular microscopy with lower than or equal to 1200 cells/mm2 belonged to the control group. The inclusion criterion was the occurrence of specular microscopy in the postoperative period over the 6- month, 1- year, and 2- year periods and the exclusion criterion […]

PURPOSE: To analyse the corneal astigmatism after transplantation as well as to demonstrate how post-surgical handling of sutures affects the refractive and visual outcome in patients submitted to cornea transplantation by keratoconus with three to six years of follow-up. METHODS: Non-controlled longitudinal observational secondary clinical study. Fifty records of patients submitted to penetrating keratoplasty between 2000 and 2002 have been reviewed, including 50 eyes of 50 patients operated under the same surgical technique by the same surgeon. Follow-up time ranging […]
