Up to the 1980’s, a professional to be updated and informed about the main advances in Medicine is generally expected to travel abroad, to attend congresses or do his training in renowned hospitals. Thus, the few doctors who were available and could afford this investment, usually became notable nationwide in subspecialties when they were back and could choose between transmitting their knowledge to their collegues or keeping it only to their practice […].

PURPOSE: To evaluate long-term results of the secondary piggyback technique used for the correction of undesired ametropia after phacoemulsification. METHODS: Retrospective study comprising of 20 eyes (19 patients). The IOL used was a single-piece PMMA with an overall length of 12.5mm, a 5x6mm oval thin-edged optic with a 10-degree haptic angulation. The same technique was used in all cases, consisting of a scleral-corneal tunnel with a 5mm opening, through which the secondary intraocular lens was implanted into the ciliary sulcus. […]

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 […]

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 […]

The discoid lupus erythematosus is an autoimmune disorder which generally affects the sun-exposed skin. Presentation of lesions on the eyelids in the absence of any other cutaneous abnormality is uncommon and the lower-eyelid involvement is seen in 6% of patients with cronic cutaneous lupus erythematosus. We have reported the case of a 40 year-old, woman who presented hyperemia, madarosis and ulceration on the lower eyelid of the left eye. She was treated for blepharitis without resolution. Before that, another similar […]

OBJETIVO: Analisar a recuperação da acuidade visual (AV) e sobrevivência do enxerto após primeiro episódio de rejeição endotelial em ceratoplastia penetrante (PK) em pacientes submetidos ao corticóide intravenoso (IV) associado ao tópico. MÉTODOS: Estudo descritivo, prospectivo, tipo série de casos envolvendo 32 pacientes com PK tratados com 2 doses de 500mg de metilprednisolona IV (com intervalo de 1 semana) associado ao acetato de prednisolona 1%. O parâmetro principal analisado foi a recuperação da AV e a regressão do edema corneano. […]

The objective is to report a 33 year old female who came to the emergency room of Ophthalmology complaining of reduced visual acuity on the left eye, in a progressive and insidious way, about two years ago. In the ophthalmological examination, she presented dilated tortuous vessels in her left bulbar conjunctiva, very high intraocular pressure and increased cupping of the optic disc. SITA-SWAP and 24:2 computed perimetry were performed on the right eye, both within normal limits. CT scans of […]

Analisamos retrospectivamente os dados clínicos de cinco pacientes com seio camerular fechado por sinéquias anteriores periféricas (SAP) secundárias à crise aguda de fechamento angular primário e submetidos à goniossinequiálise (GSL). Os pacientes apresentavam fechamento sinequial circunferencial por seis meses ou menos e foram acompanhados, no mínimo, por seis meses após a GSL. Após um acompanhamento médio de 32.4±13.9 meses, a acuidade visual melhorou em quatro (80%) olhos. Antes da GSL, a pressão intraocular (Po) variou de 34 a 58 mmHg. […]

The methodology currently used for interpretation of the cornea and anterior segment tomography for the diagnosis of corneal ectasia. Description of the clinical interpretation of anterior segment tomography (Pentacam – Oculus, Wetzlar, Germany); case report of the ectopia lentis demonstrating the importance o evaluation of the cornea and anterior segment of the keratoconus. We excluded the disease, analyzing the tomographic analysis of rates of ectasia and observe an asymmetry between nasal and temporal sides in assessing the depth map of […]

The authors review the basic aspects, etiology, clinical signs, diagnosis and treatment of the VI nerve palsy. Review the possible causes of abducent paralysis and location of determinant lesions. The clinical signs and clinical follow up are also observed in order to guide the etiology and therapeutic. The authors describe the clinical, pharmacological and surgical treatment. The authors emphasizes their proposal of VI nerve palsy correction using the isolated Carlson-Jampolsky transposition.

Carotid cavernous fistulae are an uncommon disease. They are classified as direct or indirect. In direct fistulas there is an abnormal communication between the internal carotid artery and the cavernous sinus. Indirect forms have an abnormal bypass between the meningeal branches of the internal and/or external carotid arteries and the same sinus. The purpose of this article is to provide an overview of the anatomy of the envolved area and the clinical findings, diagnostic evaluation and treatment.
