Encouraged mostly 1-) by the visibility of the scientific journals in the nonprofessional and professional environment resulted from indexation of good quality journals based on electronic data and search tools, allowing the reader (clients or colleagues) to find related publications on the internet, and 2-) by the introduction of Graduate Programs (stricto sensu – master and doctor degrees) of the main universities, and also by the need of young ophthalmologists to distinguish themselves with academic titles, many doctors may become […]

In the early ’80s, the advent of elective surgeries in order to reduce dependence of vision correction (eyeglasses or contact lenses) determined profound changes in Ophthalmology. Although refractive procedures were initially controversial, they quickly gained popularity among physicians and potential candidates. This determined a demand for developments in knowledge. With that, there was a great stimulus for research in basic and clinical chairs, which increased the understanding of various aspects of physiology, pathology, and diagnosis in corneal and ocular optics.

PURPOSE: The study of fungal invasion and pathogenicity in corneal tissue observed through the histopathological examination of specimens obtained through penetrating keratoplasty (‘PKP’) of samples obtained from an Eye Bank (‘EB’), with the aim of applying findings in diagnosis and treatment of the condition METHODS: Retrospective non-comparative case studies on samples collected between January 2006 and June 2011 based on identification data comprised of scant historical information sent by surgeons and material obtained through PKP, consisting of 38 samples from […]

OBJETIVO: Avaliar as alterações topográficas da córnea após a realização de vitrectomia via pars plana 20-gauge associada à introflexão escleral para o tratamento do descolamento de retina regmatogênico. MÉTODOS: Vinte e cinco pacientes com descolamento de retina regmatogênico foram incluídos neste estudo. Vitrectomia via pars plana 20-gauge associada à introflexão escleral foi realizada em todos os pacientes. O exame de topografia de córnea computadorizada de cada paciente foi realizado antes da cirurgia e ao sétimo dia, trigésimo dia e três […]

OBJETIVO: Descrever uma nova técnica para caracterização clínica das propriedades biomecânicas da córnea, usando sistema de imagem dinâmica não invasivo. MÉTODOS: A resposta de deformação da córnea é monitorada durante tonometria de não contato com fotografia de Scheimpflug de altíssima velocidade. O Oculus Corvis ST (Scheimpflug Technology; Wetzlar, Germany) apresenta uma câmera UHS Scheimpflug que adquire mais que 4.300 fotos por segundo com cobertura de 8mm horizontais para monitorar a resposta de deformação durante a tonometria de não contato por […]

OBJETIVO: Analisar os resultados refracionais no pós-operatório de cirurgia de catarata em olhos previamente submetidos à ceratotomia, utilizando a fórmula Haigis e os dados fornecidos pelo biômetro óptico IOL Master®. MÉTODOS: As medidas para o cálculo da LIO foram obtidas por meio da biometria óptica por interferometria de coerência parcial (IOL Master® – Zeiss, versão 5.4 e 5.5) que nos fornece o comprimento axial, a ceratometria central de 2.5mm, o diâmetro branco-a-branco e a profundidade anatômica da câmara anterior. A […]

OBJECTIVE: This study aims at observing the inhibition of cell proliferation in primary pterygium by the use in vitro of mitomicyn C, cyclophosphamide, methotrexate. METHODS: Pterigyum was removed from seven pacients between 30 and 60 years and were submitted to culture of epithelial cells. Later the effect of drugs was tested on the cells: cyclophsphamide, methotrexate, mitomicyn. The cells were observed for five days under the microscope to assess cellular proliferation, and the experiments were repeated five times RESULTS: When […]

OBJECTIVE: To evaluate the correlation of flow and stopping time intraoperative loss of attachment factors as hypertension or hipocorreções of refractive errors after Lasik. METHODS: The age ranged between 19 and 61 years (mean= 31.27 ± 9.99). The minimum follow-up period was 90 days. Individuals with: corneal topography preoperative maximum keratometry greater than 46.5D or presence of irregularities, corneal curvature postoperative simulated smaller 36.0D, pupils more 6mm; corneal thickness smaller 500 µm; Myopia more -8.0, hyperopia more +5.0DE and astigmatism […]

Sarcoidose é uma doença granulomatosa sistêmica idiopática. Afeta comumente pele, pulmões, rins e sistema nervoso central. Nos olhos afeta primariamente a úvea, conjuntiva, glândulas lacrimais e nervo óptico. Descrevemos o caso de um paciente portador de sarcoidose sistêmica com acometimento ocular assintomático.

O objetivo deste estudo foi descrever uma série de casos prospectivos de 5 olhos tratados com ranibizumabe intravítreo para glaucoma neovascular (GNV). Cinco pacientes com GNV refratário, secundário a retinopatia diabética proliferativa (4 pacientes) e oclusão de veia central da retina (1 paciente), não responsivos a terapia medicamentosa máxima tolerada e panfotocoagulação da retina, receberam ranibizumabe intravítreo (0,5 mg). Os pacientes foram vistos no 1º, 3º e 7º dia após a aplicação e conforme necessário. O sucesso foi definido como […]

Optic disc pit and macular microhole are two rare pathologies with an extremely low likelihood of coexistence, this paper will report an association of both pathologies in the same eye with the purpose of analyzing clinical manifestations, tests, angiography, OCT, retinography, biomocroscopy, treatment outcome and the connection between the optic disc pit and macular microhole.

We present a case of double ring capsulorhexis in a 81 year-old female patient. Surgical specimen was submitted to histopathologic study resulting in typical double ring capsulorhexis findings. We discuss the questioned relation to true capsular exfoliation. We call attention to the fact that it is possible to obtain a good surgical result even when the double ring is not complete – as the case presented – , since both capsular flaps are fused in a continuous form.

The neurofibromatosis type 1 is a autosomal dominant disease which the diagnosis is made based on clinical criteria. Its three main features – neurofibromas, cafe au lait macules and Lisch nodules occur in up to 90% of the pacients until puberty. We documented a clinical case of a young male pacient who had the diagnosis of neurofibromatosis type 1 and family history, describing its clinical aspects and radiological features.

Treatment of fungal eye infections represents a challenge to the ophthalmology practice. For an adequate therapeutic response, besides correct drug choice, it is necessary an effectively administration. This script gathers information about the major antifungal drugs used in eye infections, their concentrations and main administration routes.

This paper reviews and makes a critical analysis of radiofrequency in ophthalmology. Localized heating of the cornea has been apllied since 1889 for different therapeutic and surgical objectives.The principle that heating corneal tissue causes shrinking of the collagen that changes the corneal curvature. After the approval of FDA in 2004, we initiated a multicenter study in Brazil coordinated by ABC School of Medicine that resulted in an analyses of 258 patients. Inconclusion the study showed that the procedure had a […]
