Retinal Melanoma Diagnosed with the Optomap Retinal Exam

Here is a video where a retinal melanoma was initially diagnosed using the optomap® Retinal Exam.  The optomap® is a new generation of scanning laser ophthalmoscope that takes a series of 16 photos in 1/4 of a second and puts them together making a panoramic view of the back of a patient’s eye.  The optomap® allows us to view over 80% of the back of the eye without dilating the pupils.  The optomap® was also recently featured on the TV Show The Doctors.

How are Custom Soft Contact Lenses Made

Here is an interesting video from the TV show How It’s Made on how custom soft contact lenses are made.  The vast majority of soft contact lenses  prescribed today are mass produced and molded, however if you have a lot of astigmatism or wear special custom ordered contact lenses then the odds are good it was manufactured in a similar manner.

What Kind of Eyeglass Lenses are Recommended for Children?

Assessing the visual needs of your child with an eye exam is the first step in protecting your child’s vision.  It is equally important to select lenses that will not only make them see well but also protect their eyes.

Polycarbonate or Trivex lenses are the only lens types that have the potential to reduce—not increase—the risk of serious eye injury.   Polycarbonate and Lexan are used in bullet-proof windshields, safety glasses, helicopter canopies and many other hi performance applications.   Other lens types, including glass and regular plastic (CR-39)  will break into pieces upon impact.  Often the impact from an object does less damage to the victim than the broken eyeglass lenses.

Both polycarbonate and Trivex are thin, lightweight and highly impact resistant.   Kids can do crazy things and accidents can happen, therefore polycarbonate and Trivex are not just recommended for sports but should be used to protect their eyes everyday.

Trivex is highly scratch resistant making it the best option for children.  Polycarbonate is much softer and therefore less scratch resistant, however it is slightly less expensive.  Both lens materials naturally block 100% of UV light without any additional coatings.  The optical qualities of Trivex are much better than those of polycarbonate, therefore there is less distortion and reflection from an ophthalmic lens made of Trivex.  Both lens materials are available in Transitions (get darker outside, lighter inside) and accept an antireflective coating, which prevents reflections, making the lenses look transparent.

10 Must Have FireFox Browser Addons

Occasionally I depart from the usual eye care related topics and branch into something that I feel people might find useful.  My internet browser of choice is Firefox. I only use Internet Explorer when absolutely necessary, which is a very rare event indeed.  What I like about Firefox is that you can customize it with addons.  There are thousands of addons available for Firefox.  Here are a few of my must have favorites.  I use everyone of these daily.

  • Tab Mix Plus – Adds increased options and functionality to Firefox’s current tab system
  • Unites States English Dictionary – a spell checker
  • Google Toolbar for Firefox – search Google from the browser without going to the website, includes other helpful items as well
  • Adblock Plus – gets rid of pop ups and advertisements, you can tell it which pages you want the ads removed
  • Delicious Bookmarks –  Store your bookmarks online and categorize them.  Decline the option to install Yahoo’s Toolbar, Google’s is better
  • ForecastFox – gives you weather in the bottom right corner of the browser
  • Gmail Manager – Much better way to access your Gmail, especially if you have multiple accounts
  • IE Tab – sometimes only Internet Explorer works, usually only needed for an E-Commerce site
  • Remember the Milk for Gmail – My todo list integrated with Gmail
  • Sxipper – Gives me the option to enter my passwords at logon screens

That’s it those are my must have Firefox Browser Extensions/Addons.  You can search for other Firefox addons at the Firefox Addon Website.  I have also reviewed addons that are available to patients with impaired vision.

Firefox Browser Tips and Addons for Low Vision Patients

lowbrowse-icon

I started to write this post to inform patients with low vision about the added utility of using Firefox to make the screen more readable.  Very simply you can magnify the Firefox window by holding down the CTRL key and then hitting the + key or the – key as appropriate to make the entire Firefox screen change size.  The post then grew to including useful Firefox addons, which will be our next blog post.   However, in researching other Firefox addons for low vision patients I came across LowBrowse™ and I am very glad I did.  It is a great program for patients with limited vision from diseases such as macular degeneration, retinitis pigmentosa or glaucoma.

First of all the easiest way to get LowBrowse™ is directly from its developer, the Lighthouse International.  The step by step instructions are very detailed and easy to understand.  LowBrowse™ was developed in the Arlene R. Gordon Research Institute by vision scientist Aries Arditi, Ph.D. under a research grant from the National Eye Institute.  Dr. Arditi has also developed larger mouse icons which are very essential to increasing a computer’s usability for patients with low vision as well as improving the functionality of LowBrowse™ for the severely visually impaired.

Installation was easy and no different than any other Firefox addon.  Once the browser restarted a window appeared just above the Firefox tabs and below the toolbars.  This window is where the magnified text appears and is referred to the reading window.  Below the reading window is the normal Firefox browser window which is referred to as the global window.

The reading window is configurable as to the size of text, font and color.  The default color of the reading window is white print on a black background.  Initially the reading window was blank for me.  I discovered that the Firefox extension “Tab Mix Plus” was interfering with LowBrowse™.  Once I disabled the offending extension and restarted my browser my magnification window, or reading window as it is referred to in the help file, displayed text that was about 2 inches tall.

LowBrowse-Screen-Capture

Once you place your cursor over any text in the global window, the text in that paragraph will be available in the reading window by scrolling through it with the left and right arrow keys.  If the LowBrowse™ extension is enabled you can not use the left and right arrow keys for navigation in the large global screen, they are only available for scrolling text in the reading screen.

LowBrowse™ also has a text to speech function that was developed in cooperation with Charles L. Chen.  I found the text to speech function to work very well and was quite accurate on my Windows Vista PC.  The speech function worked very much like the magnification window.  You place your cursor on the text you want to read in the global window and it reads the paragraph.

I found LowBrowse™ to be a great addition to our inventory of options available for patients with low vision.  When combining Firefox’s inherent ability to magnify the webpage in the larger navigation window with the speech function and greater magnification capacity of LowBrowse™ it truly opens up the Internet to patients with low vision.

Another device we have reviewed and found useful for some low vision patients is the Amazon Kindle, for more information see our review.  Also see our review of the 10 must have Firefox Addons.

Response to “Top 5 Reasons Healthcare is Broken” on ZDNet News

The current Healthcare Debate has the potential to be the most important issue of our generation.  For good or bad this legislation will affect all of us for the rest of our lives and the lives of the generations after us.  This post is a departure from our usual posts, however, I read a blog article by an online insurance broker writing on ZDNet News giving his top 5 reasons why our healthcare system is failing and given the timeliness of the issue I felt inclined to respond.  His points are in quotes and italicized.

1. “The current system is set up to reward sickness. Doctors get paid when you see them. And you only see them when something’s wrong, right? Hospitals get paid when someone gets injured or is sick. Pharmaceutical companies make outrageous profits when their drugs are prescribed (and they lavish gifts worth more than your annual salary to the doctors who prescribe the most…see #5). Insurance companies take in more money when there are more sick people to cover. Everything revolves around us being sick.”

The current system doesn’t “reward” sickness.  I can’t imagine a cancer patient feeling rewarded.  More likely they feel  grateful for the excellent care their insurance covers and the second chance at life.  Our current system, unfortunately does not reward good lifestyle choices (see #2).  The coverage for well visits is weak at best.  It is true doctors as well as hospitals get paid when we are sick. I don’t know of a single doctor that would not welcome the chance to consult with a patient regarding preventative medicine.  Preventative care saves a ton of money in the long run and improves the public’s productivity by keeping people well, out of the hospital and in the workforce or school, home, etc.

Who is to say a profit is outrageous?  Profits are necessary to fund future medications, medical devices etc. that solve health problems that treat your family, my family, everyone.  Without a profit a drug company has no money to fund research, donate their product to the needy etc.  Regarding lavishing gifts on doctors to prescribe their meds worth more than an average citizen’s yearly income is an inflammatory statement with no basis in fact that makes the public’s blood boil, and for good reason I might add, but it has no substance.  Many years ago I would not doubt some degree of this went on.   To say or imply that “pay to prescribe” is now or was in the past a common, everyday practice that most, if not all, docs were involved in is to irresponsibly inflame the debate.

2. “We are killing ourselves. Our choices bring on diabetes, heart-attack-inducing high blood pressure and cholesterol, obesity, chronic illness, and the like. We eat crap. We supersize it. We consider the walk from the parking lot to our office exercise. We only see the doctor when we get sick.”

I agree here, however, we don’t need to nationalize healthcare to solve this problem.  We need to reward people for making the right choices. We also need to educate people that the choices they make directly influence their well being and future financial health.  Heathcare costs could be cut tremendously through educated lifestyle changes.
