With the advance in Medicine that in the last decades has been stamped by the practice based on evidence, in which clinic decisions are guided by results of scientific studies and no more only by the experience and perception of renowned professionals, more interest has progressively been pointed out on behalf of institutions engaged in teaching and medical assistance, by encouraging the carring out of clinic studies (1) […].

OBJECTIVE: Comparison of the visual performance between patients with Tecnis® MF ZM900, Acrysof® Restor® SN60D3, Acrysof® SN60AT and Acrysof® SN60WF intraocular lenses. METHODS: This prospective comparative study included 142 eyes of 71 patients in Sao Paulo University. The ophthalmologic evaluation performed included near, intermediate and distance corrected and uncorrected visual acuity, contrast sensitivity measurement and wavefront analysis. The minimum follow-up was 6 months. RESULTS: The mean age of patients was 60.7±6.6years in the Tecnis®MF, 63.1±4.4 years in-group Restor® 63.7±4.2 years […]

PURPUSE: To determine the correlation between presbyopia and body mass index. METHODS: Cross-sectional study involving 1030 patients with visual acuity of 20/20 emmetropy, aged between 36-40 years, 51-55 years and 60-65 years, excluding patients with positive test cover, anisometropy with convergence insufficiency or high correlation convergence / accommodation. Assessment of body mass index of all patients, RESULTS: Cross-sectional study involving 1030 patients with visual acuity of 20/20 emmetropy, aged between 36-40 years, 51-55 years and 60-65 years, excluding patients with […]

OBJECTIVE: Primary open angle glaucoma is a neurodegenerative disease of the optic nerve that represents one of the main causes of blindness worldwide. Familial aspects have been implicated in the development of the disease and proved in several studies. In this article, we present a systematic review of works about primary open angle glaucoma and mitochondrial DNA and a statistic analyses under a scientometric insight. METHODS: Bibliographic research of the works on mitochondrial DNA and primary open angle glaucoma was […]

PURPOSE: To determine linear regression models between Alpins descriptive indices and Thibos astigmatic power vectors (APV), assessing the validity and strength of such correlations. METHODS: This case series prospectively assessed 62 eyes of 31 consecutive cataract patients with preoperative corneal astigmatism between 0.75 and 2.50 diopters in both eyes. Patients were randomly assorted among two phacoemulsification groups: one assigned to receive AcrySof®Toric intraocular lens (IOL) in both eyes and another assigned to have AcrySof Natural IOL associated with limbal relaxing […]

OBJETIVO: Estabelecer modelos de regressão linear entre os índices propostos por Alpins com os vetores astigmáticos de Thibos, avaliando a validade e a força dessas correlações. MÉTODOS: Série de casos na qual foram avaliados prospectivamente 62 olhos de 31 pacientes de catarata com astigmatismo corneano pré-operatório entre 0,75 e 2,50 dioptrias para ambos os olhos. Os pacientes foram aleatoriamente distribuídos entre 2 grupos: um submetido a implante de lente intraocular (LIO) AcrySof ToricTM em ambos os olhos e outro grupo, […]

OBJECTIVE: Understand the behavior, functional repercussion and relationship with epidemiological factors of asteroid hyalosis (AH) and retrospective observational case series. METHODS: Fifty-eight patients diagnosed with AH (24 women and 34 men) were studied. All patients were submitted to a thorough ophthalmological examination. RESULTS: We observed a statistical association between the presence of AH and male sex (p=0,042). An increase in prevalence of this pathology was observed with increasing age. We determined an odds ration of 5,24 of a patient over […]

OBJETIVO: Compreender o comportamento dos asteroides hialoides, sua repercussão funcional em relação aos fatores epidemiológicos,de modo retrospectivo e observacional de casos clínicos. MÉTODOS: Cinquenta e oito doentes com diagnóstico de asteroides hialoides (24 mulheres e 34 homens) foram estudados. Todos os doentes foram submetidos a exame oftalmológico completo. RESULTADOS: Observamos uma associação estatística entre a presença de asteroides hialoides e o sexo masculino (p=0,042). Verificamos um aumento de prevalência desta patologia com o aumento da idade sendo o risco relativo […]
