Myopia - Symptom, Treatment And Causes

What is Myopia? What usually causes myopia? Treatment for myopia: Types of surgery to treat myopia:

What is Myopia?

Myopia is also known as nearsightedness. Myopia is defined as a refractive disorder of the eye. It has become more common in recent years. The exact cause of myopia is not yet known but studies suggest that eye fatigue due to excessive computer usage, genetic predisposition, other prolonged near vision tasks or spending longs hours in front of the television are leading causes of myopia.

What usually causes myopia?

Myopia generally occurs if the eyeball is excessively long which makes it relative to the concentrating power of the lens and the cornea of the eyes. This makes the light rays focus at a point in the front portion of the retina, rather than on the surface. Myopia usually begins during childhood. If one or both your parents have myopia, you are at a higher risk of developing myopia. It also progresses and worsens with age if proper care isn’t taken.

Treatment for myopia:

Myopia or nearsightedness can be treated by wearing contact lenses or glasses. Though this doesn’t cure myopia completely, but it prevents the power from increasing. If your degree of myopia is high, it is advisable to opt for a refractive surgery. This surgery usually eliminates the need for contacts or glasses. Excimer laser s the most common laser used for correcting vision. Contact lenses and glasses need not be worn every time of the day. It can only be worn when you want clear distance vision, like while watching a movie, looking at a chalkboard or while driving.

Types of surgery to treat myopia:

  • PRK- In this form of treatment, the laser starts to remove the corneal tissue and flattens the cornea allowing light rays to focus properly on the retina of the eye.
  • Lasik- This is the most common form of refractive procedure opted by people with myopia. In this procedure, a flap is created on the cornea surface and the laser starts removing corneal tissue till the thin flap goes back to its original position.
  • Orthokeratology- This is a non surgical procedure where you are supposed to wear special rigid gas permeable (GP or RGP) contact lenses during night which reshape your cornea while you’re asleep. This form of treatment is temporary and used to correct moderate levels of myopia. Both these procedures are great alternatives to surgery for people who are not suitable for a LASIK or a refractive surgery.
  • Phakic IOLs- These work as contact lenses, but they are surgically placed inside the eyes and are permanent. No maintenance is required for Phakic IOLs.

My dad is 75 years old. Since last october, he is suffering from mental health issues. He started to get angry on frivolous matters, talking much on unnecessary things, imagine non-existent things (like someone has stolen his dress), etc. We therefore consulted a physiatrist for medical help. Initially, since there was not much improvement in my dad’s condition the doctor increased the dosage. But when my dad became too silent, the doctor started decreasing the dosage. As the medication continued for next 5 months, my dad started behaving in reverse order (talking very less, always sleeping, lost appetite for eating, walking very slowly, getting irritated with sounds). As his condition was same even after reducing the dosage 2-3 times, we consulted another physiatrist who was highly recommended by people know to us. However, things got worse and in the first day of medication itself my dad’s health worsened. He was not able to stand / walk properly and was completely drowsy. For the next few days, the doctor changed the medication several times. Currently, he has stopped medicines for mental health issues and has prescribed medicines for improving his physical health. However, my dad hasn’t recuperated properly and still not able to walk around freely, sometimes loosing balance when standing, sitting, climbing up steps and getting down from steps, seems lost in his thoughts and don’t communicate much with us. He also has difficulty in wearing his shirts (especially, putting buttons on). He also gets confused while choosing places to sit and ends up sitting on the edge / corners of the chair and sofa. He has also lost his appetite for eating. To sum up, before we started this medication, he was able to do his daily chores all by himself without our support. But now he is completely dependent on us. We are lost for reasons for this change of behavior and physical condition of my dad. Kindly let us know, if we are doing proper medication and any suggestion you have on treatment. Following are his present medications: •syndopa 275 (4 times a day every 4 hours) •selgin 5 mg (2 times a day) •syndopa cr (1 time in night) •complete td (1 time in night) •betonin syrup (5 ml for three times) he is also taking his regular medicine for blood pressure (arkamin 100 mg and amladoc 5 mg one time each) we are also worried about him taking excessive medicines at this old age. Please help us with your valuable guidance.
