Acute Myopia - The Causes, Symptoms And Available Treatments
Acute myopia? Sounds exotic. Wasn't myopia an hereditary condition? Myopia is also known as nearsightedness. The condition has many varying degrees depending on the elongation of the eyeball. This affects the way the cornea interacts with the front of the eye called the ocular lens. The result is that you are able to see items that are close to you, but things that are at a distance become fuzzy. One of the types of myopia is called acute myopia. This is sometimes diagnosed as high myopia, but that is a misnomer. Most commonly, this type of myopia is induced by the use of certain types of drugs. Not illicit drugs, but prescription medications. Among these are some used in treating epilepsy and anti-seizure medications. Usually, myopia in general is a hereditary condition that becomes apparent in childhood and can degenerate into adulthood. At that point, the condition tends to level out and remains at that level. However, with transient acute myopia, the effects are temporary and are treated differently. Some of the drugs that are known to cause this condition are:- Sulfa analog drugs used to treat bacterial infections.
- Ganglion channel blockers used to treat some neurological disorders.
- Tetracycline antibiotics.
- Carbonic anhydrase inhibitors used to treat a range of conditions, mainly as an anti-glaucoma agent.
- Corticosteroids in treating immunity responses, electrolyte levels in the blood and basic inflammations.
- Hydrochlorothiazide used to treat edema and fluid retention.
Symptoms And Treatment
Symptoms can include many headaches as well as blurred vision that comes and goes. These symptoms are usually attributed to an increase in pressure inside the eye itself. Treatment is to discontinue the drug that caused the condition with the use of pressure reducing medications. Eyeglasses or surgery is not helpful here since the effects are, as we said earlier, temporary and will subside with time and treatment. In cases where the pressure is not reduced with these methods, a more radical therapy is needed. The treatment called for is dependent on the drug that caused the myopia to begin with. For that reason, it is absolutely necessary to consult an ophthalmologist as soon as possible. Have YOU ever suffered from this type of myopia? What caused it?
