Hyperopia in the elderly

Hyperopia in the elderly

Hyperopia is an abnormal state of refractive light. Those with farsightedness will have small eyeballs or excessively flattened corneas. Making it impossible to see objects from close up clearly But will clearly see distant objects or sometimes it may not clearly see both near and far away. Which presbyopia in medicine means presbyopia symptoms that occur from a young age and have not reached old age and farsightedness that occurs when reaching an elderly age (40 years of age and over) is called presbyopia.

Most hyperopia is congenital and is often found to be caused by heredity. However, presbyopia is not a dangerous or serious condition and can be easily fixed by wearing glasses, wearing contact lenses or surgical treatment, etc.

Common symptoms of farsightedness include:

  • Pain in the eyes or the area around the eyes
  • Stinging eyes or eyes can not fight the light
  • Eyes must be narrowed for clear vision
  • Headache due to overworked eye muscles from focusing, often a pain in the forehead area, and will have more symptoms when using more eyes. Usually, there are no symptoms in the morning. But will have a headache in the evening and if you refrain from using close-up vision pain will go away.
  • Can not see clearly objects up close, such as reading a book or threading a needle.
  • Eye discomfort or headache from prolonged vision, such as reading, writing, working on a computer, or drawing.
  • Looking blurry, especially at night.
  • A closer look is not clear faster than the appropriate age or have symptoms of eyesight in the elderly faster than common people. Usually, people with presbyopia are older than 40 years old, but those who already have presbyopia may develop visual acuity faster. In the early stages, blurred vision often occurs when the body is tired or When there is not enough light.

Hyperopia in children often shows no symptoms. But in severe farsightedness, it may cause the following symptoms.

  • Rubbing eyes frequently.
  • Problems reading books or makes you not like reading books.
  • Headache
  • Squint eyes of children with moderate farsightedness causing a lot of focus all the time Which may cause eyes to squint in.

When can Hyperopia begin to occur?
Most often farsightedness starts from childhood and as the body grows, the symptoms will go away on their own. But in cases where the development of the eyes has stopped (Children about 9 years old) and still have hyperopia problems. The eyes will adjust by adjusting the focus of the eyes. (Accommodation) to solve problems. But as we get older, the focus of the eye becomes less.

In addition, by the age of 40, our eyes have less ability to focus on close-up objects, known as presbyopia. It may be noted that the near vision is not as clear as before and may not be able to see clearly both near and far as it increases which is the cause of hyperopia.

Hyperopia is an abnormal state of refractive light. This is caused by the eyeball being too small or the cornea is not rounded enough. Shortens the distance between the cornea and the retina This causes the light from the object to become out of focus on the retina. But focus behind the retina instead which resulted in a poor visualization.

Most farsightedness is inherited. Or maybe caused by some cases such as retinopathy or eye tumors. But will be found very rarely.

Hyperopia diagnosis
The diagnosis of presbyopia starts with a consultation and an eye exam by an ophthalmologist. This includes an eye exam, an eye examination (Ophthalmoscopy), Tonometry, an eye examination equipment (Slit lamp), and may include other visual acuity tests at the discretion of the physician.

When the eyesight test results in farsightedness Your doctor will then use a device called a Retinoscope is a machine that measures the refraction of the eye. To help determine the cause of presbyopia, your doctor may also use a phoropter to measure refractive abnormalities.

Hyperopia treatment
For those who are young, There may be no need for treatment. Because the intraocular lens is flexible enough to self-adapt and correct farsightedness. But with increasing age, flexibility decreases, and correction may eventually be necessary with eyeglasses or contact lenses.

In addition, if farsighted people are found to have Which may be caused by farsightedness Causing children to focus on their eyes all the time. In this case, glasses must be corrected to save the child from a hard focus. In the case of farsightedness without squinting eyes The decision to use corrective glasses or not depends on the patient’s eyesight use. If using a lot of eyes, it may cause headaches, pain, and eye strain, so it should be resolved.

Wearing glasses or contact lenses will help to adjust focus and correct the problem of the irregular shape of the eyes. It also protects the eyes from ultra-violet (UV) rays with lenses that filter UV rays.

In addition, some patients may choose to correct hyperopia with LASIK or similar surgery. To correct the problem of refraction This procedure corrects the shape of the cornea. The surface of the eye and adjust the focus of the eyes effectively.

Vision correction surgery methods used to treat farsightedness include:

  • Laser-Assisted In Situ Keratomileusis: LASIK is a method of corneal surgery by using laser light to adjust the curvature of the cornea. So that the light is refracted and struck on the retina, Makes the image more visible.
  • Laser-Assisted Subepithelial Keratectomy: LASEK is a laser. Refine the facial tissue of the outer cornea for proper curvature It’s the same as the PRK method. But the outermost corneal surface (Epithelium) that was removed before the laser back and closed as before. To reduce irritation and helps wounds heal faster. Patients may need to wear special contact lenses for several days for recovery.
  • Treatment of the eyesight of the elderly Radio waves (Conductive keratoplasty (CK)) is a procedure that uses radio waves instead of lasers to heat a small point through the corneal tissue and cause the cornea to be curved. However, the effect of this treatment is not permanent.
  • PRK (Photorefractive Keratectomy: PRK) is a procedure similar to LASEK, using epithelium peeling off the outermost corneal surface (Epithelium) before using a laser to adjust the outer corneal tissue. Desired curve and after surgery, patients may need to wear special contact lenses for recovery.

However, it cannot be determined which treatment is best. It will depend on the condition of the eyes and the daily life of each person that is different. Therefore, people with presbyopia should consult with an ophthalmologist to determine which treatment will be most effective for them.

Hyperopia complications
Hyperopia can cause the following problems:

  • People with farsightedness and not corrected may cause the need to narrow the eyes to see clearly. Which can cause eye pain, eye strain or headache.
  • People with farsightedness and not fixed. May cause harm or accidents to oneself and others, such as driving or working with machinery.
  • Children with presbyopia may develop crossed eyes, which can be corrected by wearing specially designed glasses to correct presbyopia. Which may help treat strabismus.
  • People with farsightedness and not corrected may lead to a worse quality of life, cannot work as expected or make everyday life less enjoyable and may affect the learning process in children.

Prevention of Hyperopia
This is because farsightedness cannot be prevented. But there are ways to help protect your eyes and your vision. In the following way:

  • Always observe yourself if there is an abnormality in the eye, such as one eye is unable to see or blurred vision, seeing black spots, radiation, or rainbow around the lights, these symptoms may be signs of serious conditions, so if you encounter any such symptoms should seek medical attention.
  • Should have regular eye health checks to examine the ability of vision or check if there are any abnormalities in the eye.
  • Choose the right glasses for yourself This will help result in optimal vision. You should regularly test your eyes to see if the glasses you are using are suitable or not.
  • If a person with medical conditions such as diabetes and high blood pressure may affect vision If not properly maintained. Therefore, it should control and take care of the disease in an appropriate condition.
  • Avoid smoking, Because it can adversely affect the health of the eyes especially the deterioration of the inner membrane cells of the eyeball.
  • If you need to use your eyes for activities such as reading or writing Always turn on the lights and use the appropriate lights. This will improve vision and help keep the eyes from focusing too much so that they can lead to damage in the long term.
  • Protect your eyes from sunlight or ultraviolet rays by wearing sunglasses. Especially if you have to be outdoors and exposed to the sun for a long time or are people who need drugs that may cause sensitivity to UV rays.
  • Eat a healthy diet Especially eating green leafy vegetables and light-colored fruits such as spinach, kale, carrots, sweet potatoes, and cantaloupe. Because it can help maintain the condition of the retina for good and may help slow down the deterioration of the inner membrane cells of the eyeball as well.
