Macular Degeneration: What Happens



In AMD, the central part of the retina, called the macula, deteriorates. In the dry form, doctors often see yellow deposits called drusen in the macula. As dry AMD progresses, the macular tissue deteriorates, gradually shutting down the delivery of images to the brain. In the wet form, abnormal blood vessels grow. They leak blood and fluid (seen here), causing scarring and further damage to the macula. Both types lead to a central blind spot.

Glaucoma: What Happens


In the most common form of glaucoma, increased eye pressure leads to optic nerve damage and loss of vision. The eye is filled with circulating fluid that nourishes its internal structures. Sometimes the balance between fluid creation and exit is abnormal. The buildup of fluid increases pressure and damages the optic nerve at the back -- the bundle of 1 million nerve fibers that carry information to the brain. Without treatment, glaucoma can cause total blindness.

The bright yellow circle shows an optic nerve head that is damaged by glaucoma. The dark central area is the macula, responsible for finely-detailed central vision.

Contact Lens Solutions

Using the right contact lens solution is paramount in contact lens comfort. Using the wrong solution can cause contact lens discomfort and dryness or worse, an eye infection. Knowing which solution is right for you is the hard part.

There are two different types of contact lenses, hard/gas-permeable or soft. Gas-permeable contact lenses are rigid and are made of a silicone mix, soft lenses are a hydrophilic (loves water) plastic, the newest generation of soft disposable contact lenses are silicone based just as the gas-permeable lenses are. Silicone is a very oxygen permeable material and has been the more common soft lens material for the past several years.

Soft lens solutions: Nowadays there a basically two types of disinfecting solution, multi-purpose and hydrogen peroxide based. When you go to the store to buy new solution you may see several shelves of multi-purpose solutions (generic and name brand). For silicone based soft disposable lenses I suggest a few multi-purpose solutions that have worked well. Optifree Pure Moist, AMO Revitalens and Bausch & Lomb Bio-True or hydrogen peroxide based CibaVision Clear Care. I do not suggest generic solutions because these are a copy of an older formulation that sometimes don't work well with silicone based soft lenses.

Gas-permeable lens solutions: The most important gas-permeable lens solution is the cleaner, if your lenses are not clean they are not comfortable. There is not a lot of choices in the gas-permeable solution market and when you go to the store sometimes they are on a lower shelf. For cleaner I suggest Boston Advance cleaner, the Advance cleaner is an abrasive cleaner but less abrasive than the Boston Original cleaner. If used properly, meaning used every day and when the contact lenses are removed (not in the morning) most people don not have lipid protein build-up on their lenses after several months that have to be polished off. A quick note, Boston was bought by Bausch & Lomb several years ago and Bausch & Lomb has their own brand of cleaner which is the same as Boston.For gas-permeable wetting/soaking solutions, again Boston Advance or Original (or Bausch & Lomb), in my opinion they are very similar.

A couple of lesser known solutions that I suggest for gas-permeable lenses are Optimum by Lobob and Progent by Menicon. Optimum is a combination cleaner and soaking solution, it is not an abrasive cleaner like Boston Advance cleaner. Progent is a gas-permeable lens solution made by Menicon, it has been available to consumers for many years in Canada but only available to eye practitioners in the U.S. It is for monthly use and is a combination of two chemicals that are combined just before using it removes even the heaviest protein build-up on lenses. It is only available to purchase online via Menicon with a doctor's PIN that you can get from your eye doctor.

Most importantly, consult with your eye doctor before changing contact lens solutions to be sure they will work well with your brand and also make sure to read the instructions that accompany your solution.

Halloween Eye Safety

Halloween Eye Safety: When Costumes Really Get Scary

Editor’s Note: It’s fun for kids to put on scary costumes for trick-or-treat and Halloween parties, but you don’t want them to end up with something truly frightening – permanent damage to their eyesight. Here are some tips from pediatric ophthalmologist Kristina Tarczy-Hornoch, M.D.,of The Vision Center at Children's Hospital Los Angeles, to help you keep your kids’ eyes safe.
1. Don't Wear Decorative (Non-Prescription) Contact Lenses

The use of decorative or "costume" contact lenses is on the rise, particularly with teenagers, and the trend is causing serious concern among ophthalmologists.

It is against federal law to sell contact lenses in unlicensed outlets such as costume shops, party stores and beauty supply stores, but the law is not always followed. Decorative lenses from unlicensed manufacturers may be made from inferior plastic or may contain toxic dyes. In addition, untrained individuals may not follow proper hygiene in inserting or removing the devices. Eye infections related to improper wearing and handling of contact lenses can rapidly develop into corneal ulcers, which can cause permanent blindness.

Your best bet is to skip decorative lenses altogether in favor of scary makeup or costume items. If your child insists on wearing decorative contact lenses, you should schedule a comprehensive eye exam at an ophthalmologist’s or optometrist’s office. The doctor will be able to determine the correct size, curvature and, if needed, prescription for the lens. The doctor will also provide all-important guidance and instruction on proper handling and cleaning of contact lenses.

Purchase the contact lenses from a licensed eye care professional. This ensures the lens is ordered from a licensed contact lens manufacturer and complies with all FDA regulations for use in the eye.

Use correct contact lens care. Before inserting or removing contacts, wash your hands thoroughly to prevent infection. Never sleep in contacts and do not share them with others.

If blurred vision, redness, discomfort, swelling or discharge occurs, discontinue use of the contact lens immediately and see a physician sooner rather than later, as these may be signs of serious eye issues such as corneal abrasion, conjunctivitis, or corneal ulcer.
2. Only Use Make-Up Approved by the FDA on the Face or Around the Eyes

If your child's costume includes face paint and make-up, use a hypo-allergenic brand and pay close attention to the label. Make sure that any color additives to the face paint are FDA approved (check the Summary of Additives on the FDA website). When applying make-up near or around the eye, stay away from the lid margin, or lash line—the area where you would normally apply eye liner. If you are applying make-up very close to the eye, use only products approved for use in that area such as an eye-liner or eye shadow. Do not use blush or lip-liner to create a "red" effect, as some ingredients may not be approved for use in the eye and bacteria from the mouth can be transmitted to the eye.

To remove make-up, use cold cream instead of soap and water. If make-up gets into the eye, rinse it with cool water, preferably by having the child tilt the head back while water is poured into the eye. If redness or irritation persists, see an eye care professional as soon as possible.
3. Avoid Swords and Other Pointed Objects on Kids' Costumes

Many children will argue that they need a spear, knife, wand or sword to complete their costume. That may be true, but serious eye injuries can occur if one of these pointed objects hits a child’s eye or the eye of a friend.

If your child must carry a sword, find a belt carrier or scabbard where the sword can stay safely nestled while the kids roam the neighborhood. Buy or construct only accessories made of soft or flexible materials.

If your child does get poked in the eye, thoroughly inspect it for any signs of redness, decreased vision or pain. Eye injuries may be more serious than they appear. If your child reports pain or blurred vision in the eye or if the eye is discolored or bloodshot, you should take your child to see a doctor as soon as possible.

Soft Contact Lens Care Tips

Always wash your hands before inserting or removing contact lenses. Use a non-moisturizing hand soap.

Clean your storage case daily, rinse out your storage case with warm to hot water (including the lids) after you insert your lenses. Even with good care, you should replace your storage case every three (3) months. Most eye infections come from a dirty/old storage case.

Always close the top of the solution bottle after using and don't touch the tip of the bottle to anything.

Do not transfer solutions from one bottle to another.

Do not sleep with your lenses, unless you have been told otherwise.

Do not rinse soft lenses with tap water.

Use lubricating/re-wetting drops before you remove soft lenses. This helps prevent tearing of the lens. Soft lenses are very strong when they are wet but very brittle when they are dry.

When you are ready to remove your lenses, open the right or left side of the case first. Get into the habit of inserting your right lens first and removing your right lens first (or visa-versa). This helps you from switching your lenses.

Do not swim or use a hot tub with your soft lenses on, especially in a lake, river or the ocean. Soft lenses are roughly 50% water (or more) and they will absorb anything that it comes into contact with it, good or bad. If you swim in a pool, make sure that you wear goggles to keep the lens from washing out. Do not wear your lenses in a hot tub or sauna.

Upon lens removal, rub the lens between your fingertips or on your palm with the prescribed solution. Place the lens in the case and fill it up with solution. Before screwing on the lid, make sure the lens is covered with solution and away from the edges, make sure you don't over fill the storage case with solution.

Contact Lenses

 Who invented them?
Leonardo Da Vinci is frequently credited with introducing the idea of contact lenses in his 1508 Codex of the eye, Manual D, where he described a method of directly altering corneal power by submerging the eye in a bowl of water. Leonardo, however, did not suggest his idea be used for correcting vision—he was more interested in learning about the mechanisms of accommodation of the eye.

What To Bring With You For Your Exam
When you come to our office to see Dr. Hovander for a routine exam, there are a few things that will help us determine your best possible prescription and help in keeping your eyes healthy.
  1. Using a tape measure, determine the distance from the tip of your nose to the reading material (book, magazine, etc.). Note that distance in inches. Do the same for your computer, the tip of your nose to the computer monitor.
  2. Bring your current glasses, even if you wear contact lenses full-time. It's OK to wear your contact lenses when you come in for your exam.
  3. A list of your current medications and supplements.
  4. Your vision and medical insurance information card, ID number, etc.

Astigmatism Contact Lenses

Astigmatism means there is an irregular cornea or internal lens. Adequate correction requires two different prescriptions for each eye. Corneal astigmatism, the most common type, resulting in two different curvatures. Lenticular astigmatism has a round cornea but the internal lens has two different curvatures.

Spherical Contact Lenses: A regular soft contact lens will correct, or mask, up to .50 diopters of cylinder corneal astigmatism. Above .50 diopters  the soft lens will be distorted and vision will be blurred. A gas-permeable contact lens, however, can correct up to 3.00 diopters of corneal astigmatism.

Toric Contact Lenses: These lenses have two different powers. We can make toric lenses in soft and gas-permeable contact lenses. The soft lenses begin .75 diopters of cylinder. The toric gas-permeable lenses are usually for corrections over 3.00 diopters of cylinder.

Contact Lenses

We dispense all types of contact lenses. Our office specializes in "hard to fit" cases. We also can polish gas-permeable and hard contact lenses here in our office while you wait.

After your eye examination, you will see Richard Ackman, our Contact Lens Specialist, who will offer his expertise in determining which type of contact lenses are best suited for your visual needs.
