The first step for design a scientific study is to raise doubts which at that moment could not be solved with the information available in literature (a gap in knowledge). In clinic surveys, one should expect that the response to that doubt is to contribute to improve medical practice. The following step is to determine what population will be investigated. For example, when evaluating the efficacy of an intraocular lens (IOL) with yellow pigmentation in the prevention of macular degeneration […]

Cataract surgery is one of the most commonly-performed surgeries in the world, providing benefits to patients(1) and society as a whole(2). Despite technological advances in intraocular lenses (IOLs) to correct spherical aberrations(3), presbyopia and astigmatism(4), there are still cases where IOLs need to be explanted due to opacification of their materials(5) […].

Objetivo: Avaliar a eficácia e segurança de um laser de femtossegundo de baixa energia e alta taxa de repetição para confecção de lamelas corneanas doadoras anteriores profundas. Métodos: Este é um estudo prospectivo de investigação laboratorial. Vinte e cinco botões corneanos foram cortados com laser de femtossegundo para criar lamelas corneanas doadoras anteriores profundas (diâmetro, 10mm; espessura, 500µm). O corte a laser foi realizado com femtosecond laser LDV® na câmara anterior artificial da Ziemer®. Para obter-se uma melhor borda, as […]

Objetivo: Comparar a capacidade de detectar risco de ectasia no pré-operatório de LASIK usando o clássico ERSS (Ectasia Risk Score System) e índice Belin- Ambrósio (BAD- D) do Pentacam; e para testar o benefício de uma abordagem combinada, incluindo BAD-D e dados clínicos. Métodos: Estudo não randomizado retrospectivo envolveu dados pré-operatórios de LASIK de 23 casos que evoluíram para ectasia pós-LASIK e 266 casos estáveis após LASIK com acompanhamento mínimo de 12 meses. Dados préoperatórios clínicos e do Pentacam (Oculus, […]

Purpose: To evaluate the visual function of patients with bilateral implantation of multifocal diffractive IOL AT Lisa 809MTM by visual acuity with and without correction, contrast sensitivity curve, defocus curve and visual function questionnaire (39 VQF). Methods: Interventional clinical prospective study, which evaluated the results of 20 eyes of 10 patients who underwent phacoemulsification and IOL implantation between february and june 2012. Results: The average of residual postoperative ametropia was 0.05 ± 0.42 (-0.75 to +1.25 D) spherical diopters and […]

Purpose: Providing an objective and subjective evaluation of life quality and satisfaction level of the patients who underwent cataract surgery with implant of bifocal, multifocal and monofocal lenses. Methods: Bifocal lenses were implanted in 72 patients, aspheric multifocal lenses in 16 patients, apodized multifocal lenses in 20 patients and Monofocal lenses were implanted in 63 patients. The patients answered a 47 question questionnaire, whose results were evaluated and analyzed. Results: The level of satisfaction of the patients implanted with bifocal […]

Objetivo: Avaliar os possíveis fatores relacionados à formação de fibrina na câmara anterior após cirurgia vitreorretiniana em uma grande série de casos. Métodos: Foi realizado um estudo retrospectivo, observacional, caso-controle, onde os dados de 185 olhos de 185 pacientes submetidos à cirurgia vitreorretiniana foram avaliados. Os seguintes dados foram analisados: presença ou não de fibrina na câmara anterior na primeira semana de pós-operatório, idade, presença ou não de diabetes mellitus, calibre do sistema de vitrectomia utilizado (20,23 ou 25 gauge), […]

Objective: Evaluate how difficult it is to apply ocular topical medications based on patient observation and answers to a questionnaire. Eye drops in open eyes were compared to vaporization in closed eyes. Methods: The study was a randomized clinical trial paired and held in the months of august and september of 2012 in the ophthalmological department of Polyclinic Ronaldo Gazolla (Arcos da Lapa Campus, Faculty of Medicine, University Estáciode Sá, RJ) in 50 patients. The Optive® ophthalmic solution was applied […]

Objetivo: Verificar a influência da utilização de recursos de tecnologia assistiva no desempenho de escolares com deficiência visual em atividades em sala de recursos. Métodos: Realizou-se pesquisa qualitativa, por meio de observação e intervenção educacional em sala de recursos. A população foi composta por seis escolares com deficiência visual situados na faixa etária entre 12 e 14 anos. Os escolares fizeram exame oftalmológico e receberam prescrição de recursos de tecnologia assistiva distribuídos em recursos ópticos, não-ópticos e orientação para uso […]

The acute and nontraumatic diseases that involve the orbit are often little known by most physicians. These conditions are due to several factors, such as immune disorders, congenital, infections, vascular, among others disorders. The infectious causes correspond to more than 50% of all cases and require rapid diagnosis and management in order to minimize sequels. Computed tomography (CT) is the first line imaging method on these cases, generally being available in emergency centers and capable to provide an accurate, quick […]

Schwannoma is a rare benign neurogenic tumor. It arises from Schwann cells located at the myelin sheath of peripheral nerves. Its incidence is frequently associated with the orbit. Ocular tissues in general and eyelids in particular are rarely affected. Very few reports can be found in the literature describing eyelid schwannomas. Amongst these, we have found only two describing it affecting children. To our knowledge, this is the first case report about eyelid schwanomma in Brazil – and it involves […]

The pituitary adenoma is a tumor of slow evolution and has important visual disturbances such as low visual acuity and field defects. These symptoms lead patients to seek often ophthalmologists. In this case, we will analyze a patient with glaucoma who had an associated pituitary macroadenoma.

Fraser syndrome is a systemic condition characterized by cryptophthalmos, syndactyly and abnormal genitalia, which may be associated with urinary tract, ear, nose, larynx and skeletal abnormalities. Cryptophthalmos can be an isolated finding (that has been reported as an autosomal dominant trait) or associated with other congenital anomalies (reported as an autosomal recessive disorder). Child, female, nine month of life, evaluated in the lacrimal setor of Federal University of São Paulo. Child of consanguineous parents. Her physical examination showed total unilateral […]
