PURPOSE: To evaluate the effect of preoperative intravitreal bevacizumab (IVB) or triamcinolone (IVT) on the rate of early postvitrectomy hemorrhage in proliferative diabetic retinopathy (PDR). METHODS: Eligible eyes were assigned randomly to 1 of 3 groups: the IVB group received 1.25 mg bevacizumab, the IVT group received 4,0mg triamcinolone and the control group underwent a sham procedure. The primary outcome measure was the incidence of early postvitrectomy hemorrhage. Secondary outcome measures included changes in visual acuity (BCVA) and adverse events. […]

OBJETIVO: Avaliar o efeito no pré-operatório da injecao intravítrea de bevacizumab (IVB) ou triancinolona (IVT) sobre a taxa de hemorragia precoce pos-vitrectomia na retinopatia diabética proliferativa. MÉTODOS: Os olhos foram distribuídos em três grupos: IVB – 1,25 mg bevacizumab, IVT – 4,0 mg de triancinolona e o grupo controle – simulação da injeção. O objetivo primário foi a avaliação da incidência da hemorragia precoce pós-vitrectomia. Os objetivos secundários incluíram mudanças na acuidade visual corrigida e eventos adversos relacionados à injeção. […]

OBJECTIVE: To evaluate the safety of PRK in patients with atypical corneal topography, but without features of keratoconus in Pentacam. METHODS: Medical records of patients who underwent PRK method that presented atypical corneal topography and Pentacam rates considered normal in the pre operative were analyzed. The sample consisted of nineteen eyes of ten patients. The considered criteria of corneal irregularity were: increased curvature greater than 47D with asymmetry less than 1,5D, 1,5D displacement above the apex and inferior-superior asymmetry greater […]

OBJECTIVE: To evaluate bioglass, bioglassceramic biocompatibility in rabbit’s eviscerated cavities. METHODS: Forty- five rabbits were submitted to right eye evisceration, followed by the inclusion of bioglass and bioglassceramic I e II prosthesis in the escleral cavity. The animals were sacrificed at seven, 90 and 180 days after surgery. The animals had daily clinical exam; biochemical exam, histological analysis and morphometric evaluation. RESULTS: The animals stayed healthy during the expriment, with good cone integration to the host tissue. None cone extrusion […]

OBJECTIVE: To make an epidemiological analysis of patients with retinitis pigmentosa (RP), characterizing clinical aspects of the disease and the pattern of inheritance found in the population studied, according to the presence or not of Usher Syndrome. METHODS: 155 patients with RP were studied and the sample was divided into two groups: group 1 (n = 130) with patients diagnosed with classical RP not associated with systemic symptoms; and group 2 (n = 25) with patients diagnosed with Usher syndrome […]

Toxic anterior segment syndrome is acute inflammatory reaction caused by a noninfectious substance that enters the anterior segment, resulting in extracellular damage with necrosis and apoptosis during an immune response. We have the report of a case of toxic anterior segment syndrome (TASS), in which the authors seek to emphasize the most common causes of the appearance of these syndrome. They point out the care that must be taken in the process of sterilization of surgical material, in addition to […]

OBJECTIVE: To investigate if E-learning material improves the basal student knowledge level before attending the presential class of blindness prevention (BP) and if helps to fix this information one-month after the class. METHODS: Fourth-year medical students were randomly assigned to have a presential class of BP (Traditional group = TG) or to have a presential class of BP plus an additional E-learning material (E-learning group = ELG). This material was e-mailed one week before the presential class. The students were […]

OBJETIVO: Avaliar se um material disponibilizado através de E-learning antes de aulas presenciais de prevenção da cegueira (PC) melhora o nível de conhecimento basal dos estudantes, e ajuda a manter esse conteúdo um mês após a aula. MÉTODOS: Estudantes do quarto ano do curso médico foram aleatoriamente sorteados para ter aulas presenciais de PC (grupo tradicional = GT) ou ter aulas presenciais precedidas de material adicional por E-learning (grupo E-learning = GEL). Este material foi enviado por correio eletrônico uma […]
