Full textThe formulation of this report, entitled ‘Glaucoma Suspicion, Convergence Insufficiency and Toric Soft Contact Lenses Adaptation’, appears as the culmination of the internship phase developed for about six months, at Dr. Ergo- Ótica Aplicada, Lda Clinic, in Viseu. The glaucoma is a pathology characterized by specific alterations in the papilla and field of vision, generally followed by ocular hypertension. If not detected and treated early can compromise ocular health and visual acuity of the patient, in extreme situations can result in blindness. Early detection of glaucoma is crucial to better diagnosis and treatment. However, this does not always happen because the first damage is manifested in the peripheral visual field, which results in defects to the patient. The insufficiency of convergence is an anomaly characterised by the incapacity of obtaining and/or keeping an adequate convergence without effort, that is to say, a person’s incapacity of keeping the adequate binocular alignment in objects that get closer to a near distance (2,3). Regarding the adaptation of Contact Lenses, this becomes more and more important in an Optometrist’s everyday life. Correctly designed and adapted, the contact lenses compensate, and sometimes, reduce in a dynamic way, ammetropias, corneal irregularities and certain binocular dysfunctions, improving the visual capacity (4).In the specific case of Toric Soft Contact Lenses (LCHT), the value 0.75D assumes the maximum level accepted of uncorrected astigmatism.

Full textThis report is based on the internship that occured in the Ocular Eye Care Clinic, located in Aveiro city. The internship consisted in attending lectures, doing appointments, making and analyzing exams, in order to consolidate knowledge in the correction and treatment of multiple refractive errors, as well as binocular anomalies. The content of this work presents the development of three clinical cases: Macular Anomaly, Anomaly in Positive Fusional Vergence and the Adaptation of Toric Soft Contact Lenses. It is important to diagnose macular diseases such as macular degeneration associated with age at an early stage. If that doesn’t happen it may lead to the irreversible loss of central vision. An anomaly in a positive fusional Vergence is a binocular vision dysfunction that causes specific symptoms, which must not go unnoticed in routine consultations, since they cause instability in the visual system. The adaptation of toric soft contact lenses requires the knowledge of several stabilizing systems, as well as the materials and parameters that compose them, in order to allow the user to reach a stable visual acuity, as well as ocular comfort.

Full textThe content of this work presents the development of three clinical cases of Optometry, analysed during my internship. Suspected macular degeneration, excessive divergence and adaptation of toric soft contact lenses. The macular diseases will lead to decreased central vision, especially near vision; therefore the diagnosis should be made early in order to avoid significant visual loss. Binocular vision is of the most complex and important topic study of Optometry. If it’s not completely compensated, may cause symptoms that affect the normal functioning of vision, excessive divergence is a specific case of binocular vision. Contact lens adaptation should be mastered by Optometrists. The adaptation of toric soft contact lenses is a very rigorous field, because it requires maximum attention in the field of the lens and its properties, as well as the development of stable vision with comfort for the patient. Thus, I present below a study about on each of these subjects, over which I studied during the course of my internship, in order to increase knowledge in distinct areas of Optometry and helping to boost interest in future studies.

Full textAlthough silicone hydrogel contact lenses for extensive wear are the most widely used because of its advantages, that is allowing more oxygen with a minor amount of water and to provide a proper visual correction to waive form and handling over a period considerable time, there are some adverse effects associated with extensive use of contact lenses of this type of material. Due to the situation described above, it is important to have knowledge of the root causes of these events as well as signs and symptoms to avoid and solve the problem in the best way. For this purpose, this bibliographic review will be described adverse effects associated with the extensive wear of silicone hydrogel contact lenses, as well as signs and symptoms, treatments and carried out some experiments.

Full textIn this internship report are presented three clinical cases that were provided by my internship supervisor and where I did a careful analysis. The first clinical case is about referencing ocular pathology of a patient, where after performing several tests, including retinography and fluorescein angiography, there is a suspicion of a cystoid macular edema. There was the need to send him to an Ophthalmologist to confirm the pathology and to be made other diagnostic complementary exams if necessary, being presented the best therapy for the case. The second is about binocular vision, where after performing various tests and binocularity analysis was diagnosed an anomaly in the convergence in the patient and was proposed a visual therapy and maintenance plan because was the therapy that had better prognosis. The third case is about hydrophilic toric contact lenses, in which a patient was interested in wear contact lenses, being used different tests, including the slit lamp and the topography. After its analysis were adapted contact lenses and it was verified that the lens of the right eye was rotated, having to compensate the respective rotation, restoring the normal VA value.

Full textThis report of work is based in the presentation of 3 clinical cases observed over 6 years of clinical practice staff. Show three representative subjects on the field of vision care area, namely a case of possible pathology, another one of adaptation of a contact lens with associated pathology and at last, a case of binocular disorder not squint. In the case of clinical pathology can’t present a potential age-related macular degeneration. The importance of this exhibition lies in the fact that macular degeneration related to age is a disease that affects many patients and with some practice it can be detected with some ease in our optometry offices. Regarding the case of adjustment of contact lens, one speaks about the ephithelial arcuate lesion caused by some contact lens. This theme is relevant in the field of optometry because it is a uncommon situation, and for this reason, must be given the properly attention. Finally, a case of convergence excess which is a usual case in optometric clinical practice.

Full textO Biofilme pode ser designado como um grupo funcional de microrganismos aderidos a uma superfície estando envolvidos numa matriz exopolimérica. As bactérias organizam-se em Biofilmes, devido a, quando não estão organizadas em microcolónias terem reduzida taxa de sobrevivência. A estrutura e formação destes filmes são heterogéneas, integrando em si nichos de bactérias com graus de crescimento distintos. O estudo da relação dos Biofilmes com as lentes de contacto é pertinente, pois estas são amplamente utilizadas na correção de erros refrativos ligeiros, como na terapêutica de uma série de doenças da superfície ocular. A capacidade dos microrganismos aderirem à superfície das lentes de contacto e formarem Biofilmes desempenha um papel preponderante no desenvolvimento de infeções oculares, relacionadas com o uso destes dispositivos médicos. A formação de Biofilmes não depende só das propriedades da lente mas também dos microrganismos e da sua interação com o material. A prevenção da contaminação em lentes de contacto pode ajudar a reduzir a incidência de doenças oculares, tais como a queratite microbiana. Certas estratégias podem ajudar nesta prevenção, como a modificação dos materiais na produção das lentes. O tratamento, na maioria das infeções oculares bacterianas, é efetuado simultaneamente com antimicrobiano e com anti-inflamatório (corticosteroide). A combinação de antibiótico com corticosteroides promove a proteção contra novas infeções, bem como confere atividade anti-inflamatória, diminuindo a resposta imunitária do organismo. Nesta revisão bibliográfica vai-se abordar o modo como o Biofilme se forma e se estrutura e como interfere com as lentes de contato, bem como a história, os tipos de lentes, materiais e far-se-á uma abordagem à anatomia e fisiologia do olho. As infeções provocadas pelos Biofilmes serão mencionadas e referenciar-se-ão as bactérias mais vulgares, bem como os seus meios preventivos e as terapêuticas adequadas a cada infeção. A biofilm is a functional group of microorganisms that are attached to a surface and are involved in a exopolymeric matrix. Bacteria organize themselves into biofilms since single-cells have a reduced survival rate than microcolonies. The structure and formation of these films are heterogeneous, being integrated by niche of bacteria with different degrees of growth. The study of the involvement of biofilms with contact lenses is relevant, since there are widely used in the mild correction of optical refractive errors and in the treatment of several ocular surface diseases. The ability of microorganisms to adhere to the surface of contact lenses and form biofilms plays a major role in the development of ocular infections related to the use of these medical devices. The biofilm formation is not only dependent of the properties of the lens but also of the microorganisms and their interaction with the material. The prevention of contact lens contamination may help reduce the incidence of ocular diseases, such as microbial keratitis. Certain strategies can help prevent this, such as modifying the materials used in the production of lenses. Most bacterial eye infections are treated with the simultaneous use of antibiotic and anti-inflammatory (corticosteroid) drugs. This combination promotes a protection against new infections, as well as confer anti-inflammatory activity, decreasing the body’s immune response. This literature review will address the way in which the biofilm is formed and structured and how it can interact with contact lenses. The history and the type of lenses and materials used will also be addressed, as well as an analysis of the anatomy and physiology of the human eye. Infections caused by biofilm will be mentioned, reporting the most common bacteria, as well as the therapeutic and preventive means for each infection.

Full textPara ello se ha diseñado una fase experimental en la que se han observado, mediante microscopía óptica, las lentes procedentes de usuarios a fin de determinar la presencia o ausencia de hongos. Cuando se detectaron, y para poder proceder a su identificación taxonómica, se procedió a la realización de cultivos.
Las lentes nuevas fueron cultivadas con diferentes cepas de hongos y se valoró la frecuencia y densidad de colonización según las condiciones de cultivo establecidas.
La caracterización morfológica de las diferentes especies fúngicas, experimentadas y encontradas, se realizó utilizando microscopía óptica, confocal y electrónica de barrido.
Los resultados obtenidos indican que: el 11,82% de las lentes procedentes de usuarios mostraban contaminación. Entre los hongos contaminantes encontrados se describen tres nuevas citas, Gliomastix, Humicola y Phoma. Así mismo, se ha establecido que únicamente las cepas 93150 de Candida albicans y 2700 de Aspergillus niger fueron cepas de colonizar las lentes nuevas.
Por otra parte, se ha comprobado que la composición de los medios de cultivo, su evaporación y las características quimicas de las lentes (ionicidad e hidrofilia), son factores que influyen en la frecuencia de colonización y en la densidad de las hifas invasoras.
Finalmente, la microscopía confocal por reflexión de luz ha permitido visualizar las colonias internas y su grado de penetración en el material de la lente.
Las conclusiones obtenidas representan una contribución al conocimiento de los fenómenos determinantes del desarrollo de hongos en los diferentes polímeros estudiados. Suponen, además, un avance en el campo de la contactología clínica y explican algunos de los problemas.
