Continuing medical updating is crucial for the safety and good quality of medical practice. Today, the less expensive, easy and trustful way of acquiring medical knowledge is through literature review in electronic data banks, which are available on the internet. Accordingly, a minimum knowledge on behalf of the reader is necessary to critically evaluate scientific articles and not to have his clinical practice based on information which cannot stand for the truth (1,2) […].

Complaints of headache compatible with different aetiologies are very common in the clinical practice of neurologists, general practitioners, otorhinolaryngologists, ophthalmologists, dentists, and even psychiatrists […].

PURPOSE: To investigate the perception of physicians about the experience of ambulatory with children who have a serious eye disease and how they understand their interference in the mother-child relationship. METHODS: Semi-structured interviews were performed with ophthalmologists (sectors of retina, glaucoma, anterior segment and pediatric ophthalmology), and observation of outpatient appointments of a public hospital during three months. RESULTS: Idealization of the physician’s and mother’s role; physician’s difficulties on giving the diagnosis; and the acknowledgment that the professionals have an […]

OBJECTIVE: Evaluate induced astigmatism in progressive addition lenses into deflectometer measurements. METHODS: Eleven progressive addition lenses were included with power away from +1.00D and addition 2.00D. Induced astigmatism was assessed twelve points in the zone intermediate, with six on each side of the progressive corridor in deflectometer. RESULTS: There are significant differences between the sums of induced astigmatism on each side of the corridor and in the general in progressive addition lenses studied, with coefficient of variation with strong dispersion […]

OBJECTIVE: We intend to evaluate the prevalence of visual disorders among 8 to 10-year-old students from a public school in Pouso Alegre, state of Minas Gerais, as well as verify the possible legitimacy of the correlation between a poor school performance and some kind of visual deficit. METHODS: We conducted a transversal and quantitative study whose target were the students enrolled in the elementary course (2nd to 4th grade) of Pio XII Municipal School in the academic year of 2009. […]

OBJECTIVE: Evaluate the knowledge of medical students from Universidade Estadual de Londrina (UEL), about refractive surgery, as well as analyzing the percentage of students that presents refractive errors, their correction methods and their interest (or not) in the surgical procedure. METHODS: We conducted a survey using self-evaluation questionnaire (previously tested) among 154 medical students from first to fourth year, between september and november 2011. RESULTS: It was reported that 70.8% of students had some type of refractive error, and myopia […]

PURPOSE: To evaluate the outcome and safety of phacoemulsification performed under topical anesthesiain cases with several complexities. METHODS: Cases performed under topical anesthesia from january 2009 to april 2011 were analyzed. Variables analyzed included patients age, sex, race, systemic diseases, eyes comorbidities, type of cataract, visual acuity before and after the surgery, complications, number of conversions to peribulbar anesthesia and IOL power. Patients with uncompleted data were excluded from analysis. RESULTS: A total of 111 eyes were analyzed; only cases […]

OBJECTIVE: The aim of this study was to determine the learning styles of fifth-year medical students who attended the ophthalmology course and to also determine the correlation with their academic performance. METHODS: Kolb’slearning style and neurolinguistic programming (NLP) questionnaires were applied and related tothe final grades obtained. The variables were analyzed using Pearson’s r test. RESULTS: I trevealed a relation between the variables of learning styles and academic performance (p < 0.05).According to Kolb’s model, students with better performance were […]

Os autores apresentam um caso de paciente com lesão neovascular predominantemente hemorrágica com degeneração macular relacionada à idade, tratada mensalmente com injenções intravítrea com ranibizumab. Discutem sua evolução, que apesar da boa resposta terapêutica, necessita de maiores estudos para confirmação de seus resultados.

To describe the electrophysiological alterations in a very rare case of Oguchi’s disease. A 17-year-old italian girl complaining of night blindness underwent complete ophthalmological exams, including electrophysiological tests. Rod responses were nondetectable in full-field electroretinogram (ERG). The photopic ERG funtions, including the 30 Hz flicker ERG response was normal, while the scotopic b-wave was diminished in amplitude. The electrooculography (EOG) ratios within the normal range were 208% in the right eye and 222% in the left eye. The Mizuo-Nakamura phenomenon […]

Conjunctival cysts in anophthalmic socket may have functional and aesthetic implications for the patients.Among the available treatment options, the use of trichloroacetic acid is relatively recent. Our reported cases showed a good outcome after 30 days of treatment, that was well tolerated by patients, with greater conjunctival tissue preservation.

Saethre-Chotzen syndrome is a very rare congenital syndrome characterized by craniosynostosis. The incidence of it is around 1: 50,000 live births. Intelligence is usually normal, but a few affected individuals may have mild to moderate mental retardation. Children with Saethre-Chotzen syndrome should be evaluated by members of an experienced interdisciplinary team as treatment usually involves many different specialities. The strabismus surgery in these patients is difficult, because they usually have anomalous insertion and misdirection of the extraocular muscles. Imaging techniques […]

Distrofia viteliforme foveomacular do adulto é uma patologia rara. Menos de 1% dos casos relatados mostram permeabilidade capilar perifoveal. O acompanhamento de 3 anos deste paciente revelou uma forma rara, ainda pouco documentada. O paciente era uma mulher de 40 anos de idade com acuidade visual normal, mas com queixa de metamorfopsia leve no olho esquerdo. A retinografia mostrou uma área sub-retiniana amarelada, perifoveal, com hiperfluorescência na angiofluoresceinografia. O seguimento mostrou, em 3 anos, que a incompetência capilar desapareceu e […]

We present a case of late high progressive astigmatism following penetrating keratoplasty for keratoconus, which was associated with peripheral thinning in the donor-receptor area, which may be recognized as recurrence of ectasia. Treatment was accomplished with Cvintal’s Topoplasty assisted by femtosecond laser for a “top hat”, followed by resuture with peroperative adjustment guided by ceratoscopy.

Diabetic retinopathy is the leading cause of blindness among the working population in the developed world. The prevalence of diabetic retinopathy increases with duration of diabetes, and nearly 100 percent of patients with type I diabetes and more than 60 percent of those with type II have some signs of diabetic retinopathy after 20 years.A number of approaches have proved to be useful in the treatment of diabetic retinopathy, such as laser photocoagulation and tight systemic control of blood glucose, […]
