What do Amblyopia, Strabismus, and Convergence Insufficiency all have in common? These are all serious and relatively common eye conditions that children can have.

Did you know that 80% of learning comes through vision? The proverb that states ”A picture is worth a thousand words” is true!  If a child has a hard time seeing, it stand to reason that she will have a hard time learning.

Let’s explore Amblyopia, or “lazy eye”. It affects 3-5% of the population, enough that the federal government funded children’s yearly eye exams into the Accountable Care Act or ObamaCare health initiative. Amblyopia occurs when the anatomical structure of the eye is normal but the “brain-eye connection” is malfunctioning. In other words, it is like plugging your computer into the outlet but the power cord is faulty.

Amblyopia need to be caught early in life--in fact if it is not caught and treated early (before age 8) it can lead to permanent vision impairment. Correction with glasses or contacts and patching the good eye are ways it is treated. Most eye doctors agree that the first exam should take place in the first year of life. Early detection is a key.

Strabismus is a condition that causes an eye to turn in (esotropia), out (exotropia), or vertically. It can be treated with glasses or contacts, and surgery, if needed. Vision therapy or strategic eye exercises prescribed by a doctor can also improve this condition.

When we read, our brain tells our eyes to turn in to a comfortable reading posture. In Convergence Insufficiency, the brain tells the eyes to turn in, but they instead turn out, causing tremendous strain on that child’s eye for reading. Another tell tale sign of this condition is the inability to cross your eyes when a target approaches. The practitioner will see instead, that one of the eyes kicks out as the near target approaches. This condition can be treated with reading glasses or contacts, and eye exercises that teach the muscles of the eye to align properly during reading. Vision therapy is the treatment of choice for Convergence Insufficiency.

It is important to understand the pediatric eye and all the treatments that can be implemented to augment the learning process. Preventative care in the form of early eye examinations can mean the difference between learning normall or struggling badly. Remember, a young child can’t tell you if he hasa vision impairment. For the success of the child, be proactive by scheduling an early vision exam.

Have you ever seen a temporary black spot in your vision? How about jagged white lines? Something that looks like heat waves shimmering in your peripheral vision?

If you have, you may have been experiencing what is known as an ocular migraine. Ocular migraines occur when blood vessels spasm in the visual center of the brain (the occipital lobe) or the retina.

They can take on several different symptoms but typically last from a few minutes to an hour. They can take on either positive or negative visual symptoms, meaning they can produce what looks like a black blocked-out area in your vision (negative symptom), or they can produce visual symptoms that you see but know aren’t really there, like heat waves or jagged white lines that look almost like lightning streaks (positive symptoms).

Some people do get a headache after the visual symptoms but most do not. They get the visual symptoms, which resolve on their own in under an hour, and then generally just feel slightly out of sorts after the episode but don’t get a significant headache. The majority of episodes last about 20 minutes but can go on for an hour. The hallmark of this problem is that once the visual phenomenon resolves the vision returns completely back to normal with no residual change or defect.

If you have this happen for the first time it can be scary and it is a good idea to have a thorough eye exam by your eye doctor soon after the episode to be sure there is nothing else causing the problem.

Many people who get ocular migraines tend to have them occur in clusters. They will have three or four episodes within a week and then may not have another one for several months or even years.

There are some characteristics that raise your risk for ocular migraines. The biggest one is a personal history of having migraine headaches. Having a family history of migraines also raises your risk, as does a history of motion sickness.

Although the symptoms can cause a great deal of anxiety, especially on the first occurrence, ocular migraines rarely cause any long-term problems and almost never require treatment as long as they are not accompanied by significant headaches.

So if symptoms like this suddenly occur in your vision, try to remain calm, pull over if you are driving, and wait for them to go away. If they persist for longer than an hour, you should seek immediate medical attention.
