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 […]

OBJECTIVE: To analyze refractive results in postoperative cataract surgery in eyes previously submitted to keratotomy using Haigis formula and data provided by IOL Master®optical biometer. METHODS: The measurements for IOL calculation were obtained through optical biometry by partial coherence interferometry (IOL Master®– Zeiss, 5.4 and 5.5 version) that provides us with the axial length, the central keratometry of 2.5mm, white-to-white diameter and anterior chamber anatomical depth. The formula chosen was Haigis. The surgical technique applied was with the scleral incision […]

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 […]

Sarcoidosis is an idiopathic systemic granulomatous disease. It commonly affects the skin, lungs, kidneys, and central nervous system. In the eyes it primarily affects the uveal tract, conjunctiva, lacrimal glands and optic nerve. Here in we describe the case of a patient with systemic sarcoidosis and asymptomatic eye inflammation.

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.

The purpose of this study was to describe a prospective case series of 5 eyes treated with intravitreal ranibizumab injection for neovascular glaucoma (NVG). Five patients with clinically uncontrolled NVG secondary to proliferative diabetic retinopathy (4 patients) and central retinal vein occlusion (1 patient), non-responsive to maximal tolerable medication and panretinal photocoagulation, received intravitreal ranibizumab injection (0.5 mg). Patients were seen at 1st, 3rd and 7th day after the ranibizumab injection and when it was necessary. Success was defined as […]
