O primeiro laser (Light Amplification by Stimulated Emission of Radiation Light – ampliação de luz por meio da emissão estimulada de radiações) foi desenvolvido pelo físico americano Theodore H. Maiman em 1960 com cristal de rubi(1), dando continuidade aos estudos pioneiros de Albert Einstein relacionados com a Teoria Quântica da Radiação. Apesar das importantes limitações relacionadas com a não estabilidade e da duração do pulso inadequada deste primeiro laser de rubi, o trabalho de Maiman pode ser considerado como a epifania […]

OBJETIVO: Relatar os resultados de uma nova técnica para o tratamento de bolsa hiperfuncionante, assim como seus critérios diagnósticos. MÉTODOS: Vinte olhos (20 pacientes) com hipotonia ocular causada por bolsa hiperfuncionante após trabeculectomia com mitomicina C foram tratados com ressecção da bolsa. O diagnóstico de bolsa hiperfuncionante obedeceu aos seguintes critérios: pressão intraocular inferior a seis mmHg (tonometria de Goldmann); ausência de inflamação do segmento anterior ocular; presença de bolsa fistulante elevada e/ou difusa e avascular com ou sem microcistos; […]

PURPOSE: to evaluate the long-term results of the prophylactic use of Mitomycin C in inhibiting haze formation after photorefractive keratectomy (PRK) for high myopia. METHODS: This retrospective, descriptive and longitudinal study comprised 59 eyes (30 patients). The inclusion criteria were a spherical equivalent correction over -4,00 diopters, corneal thickness greater than 480 µm, no prior surgery, ocular trauma and ocular and systemic diseases. After PRK, the eyes were treated with a single intraoperative dose of MMC 0.02% applied topically with a […]

OBJECTIVE: Evaluate how difficult it is to apply ocular topical medications with and without an eye dropper facial applicator based on patient observation and answers to a questionnaire. METHODS: The study was a controlled and randomized clinical trial performed in 50 patients during the years of 2009 and 2010 in PSF – Lapa. Eye drops were applied with and without aid of an eye dropper facial applicator. Each individual tested applied randomly on one of their eyes an eye drop […]

PURPOSE: To know characteristics and difficulties to access patients’ treatment selected to keratoplasty in community projects carried out in a university hospital in São Paulo. METHODS: A questionnaire was applied on patients in two keratoplasty campaigns performed by the hospital. Was analyzed the following variables: gender, age, income, education, number of previous ophthalmologists ‘appointment, visual acuity in the better eye, diagnosis, indication for keratoplasty, knowledge about it, the eye disease and the existence of limitations on lifestyle and possible complications […]

OBJETIVO: Demonstrar a magnificação corneana utilizando o azul de tripan na cirurgia de catarata. MÉTODOS: Oito olhos de oito pacientes submetidos à facoemulsificação com implante de lente intraocular foram envolvidos neste estudo. Após corar a cápsula anterior do cristalino com azul de tripan 0,1% e realizar a capsulotomia circular contínua, a cápsula excisada foi colocada sobre a superfície corneana. Após observar e aferir a relação entre a borda da cápsula anterior excisada e a abertura da cápsula intracameral, o efeito […]

OBJECTIVE: Establish an epidemiological analysis of patients assisted in an urgency service of a university eye hospital (Hospital São Geraldo). METHODS: This is a prospective and descriptive study, conducted from september 2005 to january 2006. A questionnaire was used for the purpose of gathering daily information about all the patients assisted in the service. Information was collected on age, sex, occupation, ethnicity, origin of the patient, primary diagnosis (according to International Classification of Disease ICD 10 ) and the approaches […]

The anophthalmia is a rare eye condition characterized by the absence of one or both eyes, the etiology is not elucidated, and may be congenital, acquired or associated with other systemic syndromes. Regarding etiology, have been described in the literature chromosomal aberrations, genetic mutations and environmental factors as responsible for the appearance of the anomaly. There is no consensus about the actual incidence of anophthalmia, due to the scarcity of official data, especially in Brazil. In this study we report […]

The Urrets-Zavalia Syndrome presents well described ocular findings, even though its physiopathology is still unsure. Iris ischemia is the most common proposing mechanism. We describe two cases that underwent deep lamellar keratoplasty (DLK) performed by the same surgeon and developed the syndrome. In the first case, the surgical indication was for corneal opacity treatment and, in the second case, for keratoconus treatment. During the post-operatory, both patients developed fixed dilated pupil, which didn’t regress completely inspite of the onset treatment.

OBJETIVO: Relatar um caso de paciente com Vasculopatia coroidiana polipoidal com edema macular cistóide e a resposta ao tratamento com Ranibizumab intravítrea como monoterapia MÉTODOS: Uma paciente com 62 anos foi referida por seu oftalmologista para avaliação retiniana . Apresentava acuidade visual com correção de 20/100 no olho esquerdo e 20/20 no olho direito. A avaliação do segmento anterior era normal em ambos os olhos. No exame de fundo de olho e retinografia fluoresceínica apresentava numerosas drussas pequenas e edema […]

Case report of a 18-year-old male patient with Alport’s syndrome, who presented with renal failure and hearing loss reporting a progressive loss of vision acuity. Slitlamp examination revealed bilateral anterior lenticonus. The patient underwent pre and post-operative corneal and anterior segment tomography with a rotating Scheimpflug system (Pentacam), integrated whole eye (individual laser beam ray tracing) and corneal surface (Placido) wavefront aberrometry (i-Trace). Phacoemulsification and single piece hydrophobic IOL implantation (Acrysof® SN60AT) was performed uneventfully in both eyes. Pre op […]

Age-related macular degeneration is a major cause of central vision loss and is the leading cause of blindness for people aged over 60 years. PURPOSE: To investigate the efficacy of intravitreal injection of Ranibizumab (anti-VEGF) in the treatment of choroidal neovascularization nonsubfoveal, extra-foveal or juxta-foveal, caused by age-related macular degeneration and revision paper. METHODS: The study design was descriptive and transverse.15 patients with nonsubfoveal choroidal neovascularization caused by age-related macular degeneration, were treated with intravitreal injection of Ranibzumab per month, […]
