Objectives: Determine if retrobulbar optic nerve horizontal diameter measurement or reflectivity correlates with the optic disc excavation diameter relation in glaucoma, considering: measurements correlation, the sensitivity and specificity between the methods and which value has greater sensitivity and specificity to differentiate patients with and without glaucoma. Methods: In a masked study, the optic nerves of 38 patients with open angle primary angle glaucoma and 37 control patients were examined for retrobulbar echographic determination of their A mode (DNA) and their […]

Objective: In the presence of an irregular cornea, like in keratoconus, the corneal epithelium has a different profile “masking” the irregular corneal stroma surface. Topographical analysis without considering the epithelium effect can result in an incorrect assessment, affecting the accuracy of any topography guided treatment. The aim of this study was to evaluate the “masking” effect of the corneal epithelium on corneal curvature in patients with keratoconus, comparing topographical findings before and after removal of the epithelium during Crosslinking (CXL). […]

Objective: to evaluate how much decreases intraocular pressure (IOP) with TRAVAMED® (travoprost 0,004%) (Germed, Brazil) in patients with primary open angle glaucoma (POAG) and ocular hypertension (OH) and possible side effects. Methods: controlled and randomized study, it was evaluated 70 eyes of 38 patients with age of 18 years old or more diagnosed with POAG and OH. All the patients had TRAVAMED® as first drop for treatment used once daily (at night) and 30 days later they had IOP measured […]

Objective: To evaluate the sensitivity and specificity of the WINROP algorithm for predicting retinopathy of prematurity (ROP) in a population of Portuguese preterm infants. Methods: Retrospective study of all newborns who underwent ROP screening at Hospital Universitário do Porto from January 2010 to May 2016. Gestational age (GA), birthweight and weekly postnatal weight measurements of the newborns, up to a postmenstrual age of 35-36 weeks, were entered in the online application of WINROP, which signals with an alarm the newborns […]

Objective: To describe and analyze the prevalence of visual impairment in municipal public school students in Caceres, Mato Grosso. Methods: A transversal study of 489 school children from the second and third years of elementar school in 13 municipal schools in Caceres, attended between December 2017 and January 2018. Visual acuity was evaluated using Snellen optometric chart and considered normal when higher than 0.7 or 20/30. Results: Of the four hundred and eighty-nine children were evaluated, eighty-five (17.4%) had low […]

Objective: To evaluate the long-term efficacy of autologous platelet -rich plasma (PRP) in the symptomatic dry eye of diabetic patients after 6 months of treatment suspension. Methods: A single intervention group, prospective study, series of cases; ten diabetic patients with refractory dry eye disease who used PRP and were reassessed 6 months after discontinuation of treatment. At the initial stage 221 diabetic patients were evaluated for dry eye, of these 12 were submitted to CPC, and evaluated for symptoms, Ocular […]

The Pierre Robin Syndrome (PRS) consists of a triad of anomalies characterized by micrognathia, glossoptosis and fissure of the palate, usually associated with other syndromes e occasionally associated with ocular variations. In Duane Retraction Syndrome (DRS), there is a failure in the lateral rectus innervation by the VI cranial nerve, with anomalous innervation of the lateral rectus by fibers of the III nerve. Even though PRS has already been associated with more than 50 other syndromes, there is not any […]

The present report reports a case of conjunctivitis caused by Ralstonia pichettii in an immunocompetent patient wearing a contact lens. The bacterium isolated from the solution used to disinfect R. pichettii does not belong to the human microbiota but infects immunodepressed patients and is present in aqueous solutions. There is no standardization of sensitivity for this bacterium and few antibiotics have been tested for non-fermenting glucose bacteria. Due to the reduced antimicrobial sensitivity profile demonstrated by R. pichettii, it is […]
