Fotofobia

O que é

A Fotofobia é uma grande intolerância e sensibilidade a luz, ela pode ser promovida por uma doença ocular.

Há dois tipos de fotobia: Crônica e Aguda.

É importante procurar um oftalmologista a qualquer sinal de alteração ocular, principalmente ao perceber uma sensibilidade anormal a luz.

O médico irá avaliar se é um caso de fotofobia comum ou um sintoma inicial de problemas nos olhos. Somente os exames oftalmológicos poderão definir qual o tratamento deverá ser realizado para fotofobia.

Caso for diagnosticado uma doença ocular o médico realizará o tratamento da doença para evitar consequências mais graves.

Fotofobia

Essa sensibilidade varia de pessoa para pessoa, depende de vários fatores. A fotofobia pode estar relacionada com doenças inflamatórias, degenerativas. São vários tipos de patologias que aumentam a fotofobia.

A sensibilidade à luz é a incapacidade para tolerar a luz, medicamente conhecida como fotofobia. Em alguém que é sensível à luz, qualquer tipo de fonte de luz (luz solar, luz fluorescente, luz incandescente) pode causar desconforto.

Fotofobia tipicamente causa uma necessidade de espremer ou fechar os olhos, e dor de cabeça , náuseas , ou outros sintomas podem estar associados com fotofobia.

Os sintomas podem ser piores com luz brilhante. As pessoas com olhos claros são mais propensos a ter sensibilidade à luz brilhante do que aqueles com olhos mais escuros pigmentadas.

A sensibilidade à luz é causada por um número de condições que afetam o olho, bem como condições que afetam todo o corpo.

Fotofobia

Fotofobia é um sintoma de intolerância anormal à percepção visual de luz. Como um sintoma médico, fotofobia não é um medo mórbido ou fobia , mas uma experiência de desconforto ou dor para os olhos devido à exposição à luz ou por presença de física real sensibilidade dos olhos.

Embora o termo é, por vezes, adicionalmente aplicada ao anormal ou irracional medo da luz, como heliofobia.

Causas

Os pacientes podem desenvolver fotofobia como resultado de várias condições médicas diferentes, relacionadas com o olho ou o sistema nervoso. Fotofobia pode ser causado por um aumento da resposta a luz de partida em qualquer passo do sistema visual , tais como:

Muita luz que entra no olho. O excesso de luz pode entrar no olho, se for o caso, tal como com a abrasão da córnea e lesões da retina, ou se a sua pupila não é capaz de contrair normalmente (visto com danos no nervo oculomoto ).

Devido ao albinismo, a falta de pigmento na parte colorida dos olhos (íris) torna-os um pouco translúcida. Isto significa que os diafragmas podem não bloqueiam completamente a entrada de luz no olho.

Hiperestimulação dos fotorreceptores na retina.

Impulsos elétricos excessivas para o nervo óptico.

Resposta excessiva no sistema nervoso central.

Tom nervo trigêmeo elevada (como é nervo sensorial no olho, tom elevado faz com que seja mais reativo). Tom trigeminal elevada faz com que a substância P elevada que faz com que a hipersensibilidade. Muitas vezes devido a mandíbula desalinhamento.

As causas mais comuns de fotofobia incluem enxaquecas , TMJ, catarata , síndrome de Sjögren , Mild lesões cerebrais traumáticas ( MTBI ), ou graves doenças oftalmológicas tais como uveíte ou abrasão corneana .

Tratamento

O melhor tratamento para a sensibilidade à luz é tratar a causa subjacente. Uma vez que o fator desencadeante é tratada, fotofobia desaparece em muitos, mas não todos os casos.

Pessoas com fotofobia irá desviar os olhos da luz direta, como a luz solar e sala de luzes. Eles podem procurar o abrigo de um quarto escuro. Eles podem usar óculos concebidos para filtrar a luz periférica e de abas largas chapéus de sol.

Usando óculos escuros em ambientes fechados podem piorar os sintomas ao longo do tempo como ele vai adaptar a retina que agrava sensibilidade à luz. Sintomas de fotofobia interior pode ser aliviada com o uso de lentes coloridas precisão (por exemplo, FL-41) que bloqueiam o fim verde para azul do espectro da luz, sem borrar ou impedir a visão.

QUESTION 1 You are managing a SharePoint farm in an Active Directory Domain Services (AD DS) domain. You need to configure a service account to use domain credentials. What should you do first? A. Configure the service account to use a domain user account. B. Register the domain credentials in the Farm Administrators group. C. Configure the service account to use a local user account. D. Register the domain credentials as a SharePoint managed account. Correct Answer: D Explanation QUESTION 2 A company named Contoso, Ltd. has a SharePoint farm. The farm has one Search service application configured. The Search service application contains five crawl databases, all of which contain content. Contoso plans to crawl knowledge base content from its partner company Litware, Inc. The knowledge base content must be stored in a dedicated crawl database. You need to configure crawling. What should you do? A. Add a crawl database that contains the Litware knowledge base to the existing Search service application. B. Provision a new Search service application. Configure the service application to crawl the Litware knowledge base content. C. Set the MaxCrawlDatabase parameter to 6. D. Create a dedicated Microsoft SQL Server instance for the Litware crawl database. Correct Answer: B Explanation Explanation/Reference: The maximum number of crawl databases is 5 per Search service application so we need another Search service application. This maximum limit is increased to 15 with an Office 2013 update but the question doesn't mention that this update is installed so we have to assume the question was written before the update was released. QUESTION 3 A company uses SharePoint 2013 Server as its intranet portal. The Marketing department publishes many news articles, press releases, and corporate communications to the intranet home page. You need to ensure that the Marketing department pages do not impact intranet performance. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.) A. In Central Administration, set up a User Policy for the Super User and Super Reader accounts. B. Configure IIS to use the Super User and Super Reader accounts for caching. C. Use the Farm Configuration Wizard to configure the Super User and Super Reader accounts. D. Use Windows PowerShell to add the Super User and Super Reader accounts. Correct Answer: AD Explanation Explanation/Reference: A: The way to correct this problem is to first create two normal user accounts in AD. These are not service accounts. You could call them domain\superuser and domain\superreader, but of course that's up to you. The domain\superuser account needs to have a User Policy set for that gives it Full Control to the entire web application. D: If you are using any type of claims based authentication you will need to use Windows PowerShell. And Windows PowerShell is the hipper more modern and sustainable option anyway. If you are using classic mode authentication run the following cmdlets on one of your SharePoint servers: $w = Get-SPWebApplication "http:///" $w.Properties["portalsuperuseraccount"] = "domain\superuser" $w.Properties["portalsuperreaderaccount"] = "domain\superreader" $w.Update() If you are using claims based authentication run these cmdlets on one of your SharePoint servers: $w = Get-SPWebApplication "http:///" $w.Properties["portalsuperuseraccount"] = "i:0#.w|domain\superuser" $w.Properties["portalsuperreaderaccount"] = "i:0#.w|domain\superreader" $w.Update() Note: * If you have a SharePoint Publishing site and you check the event viewer every once in a while you might see the https://www.pass4itsure.com/70-331.html following warning in there: Object Cache: The super user account utilized by the cache is not configured. This can increase the number of cache misses, which causes the page requests to consume unneccesary system resources. To configure the account use the following command 'stsadm -o setproperty -propertynameportalsuperuseraccount -propertyvalue account -urlwebappurl'. The account should be any account that has Full Control access to the SharePoint databases but is not an application pool account. Additional Data: Current default super user account: SHAREPOINT\system This means that the cache accounts for your web application aren't properly set and that there will be a lot of cache misses. If a cache miss occurs the page the user requested will have to be build up from scratch again. Files and information will be retrieved from the database and the file system and the page will be rendered. This means an extra hit on your SharePoint and database servers and a slower page load for your end user. Reference: Resolving "The super user account utilized by the cache is not configured." QUESTION 4 You are managing a SharePoint farm. Diagnostic logs are rapidly consuming disk space. You need to minimize the amount of log data written to the disk. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.) A. Set the log event level to Information. B. Set the log event level to Verbose. C. Set the log trace level to Medium. D. Set the log trace level to Verbose. E. Set the log event level to Warning. F. Set the log trace level to Monitorable. Correct Answer: EF Explanation Explanation/Reference: E: Event Levels Warning, Level ID 50 Information, Level ID: 80 Verbose, Level ID: 100 F: Trace levels: Monitorable: 15 Medium: 50 Verbose: 100 Note: When using the Unified Logging System (ULS) APIs to define events or trace logs, one of the values you must supply is the ULS level. Levels are settings that indicate the severity of an event or trace and are also used for throttling, to prevent repetitive information from flooding the log files. Reference: Trace and Event Log Severity Levels QUESTION 5 A company's SharePoint environment contains three web applications. The root site collections of the web applications host the company intranet site, My Sites, and a Document Center. SharePoint is configured to restrict the default file types, which prevents users from uploading Microsoft Outlook Personal Folder (.pst) files. The company plans to require employees to maintain copies of their .pst files in their My Site libraries. You need to ensure that employees can upload .pst files to My Site libraries. In which location should you remove .pst files https://www.pass4itsure.com/70-342.html from the blocked file types? A. The File Types area of the Search service application section of Central Administration B. The General Security page in the site settings for the site collection C. The Blocked File Types page in the site settings for the site collection D. The General Security section of the Security page of Central Administration Correct Answer: D Explanation
