(H52.0) Hypermetropia

Hypermetropia Introduction

Hypermetropia refers to the abnormal defect of vision in which a person is able to focus on objects at a distance, but not on close objects. This is called nothing but long-sight. Often, it strikes a person at an early age i.e. when the child is under 5 years of age. However, elders are not immune to it as 5-10% of the population can get affected by Hypermetropia.  It occurs due to the rupture of the lens. The smallness of eyeball can also cause Hypermetropia. By way of wearing glasses studded with converging lenses the problem of Hypermetropia can be overcome.

Symptoms of Hypermetropia

The symptoms of Hypermetropia are liable to be differentiated from one individual to another in the following manner:

  • Headache
  • Eye strain (pulling sensation, burning)
  • Squinting
  • Difficulty in watching at close distance
  • Blurred distance vision
  • Eye weariness when reading

Treatment of Hypermetropia

The treatment for Hypermetropia can be done through eyeglasses, contact lenses, or surgery. Eyeglasses are the precise, uncomplicated, and the safest method to correcting hyperopia. However, if the patient suffers from any aligning eye conditions, then the contact lenses cannot be worn by him/her.

Causes of Hypermetropia

There are the underlining reasons behind a child developing Hypermetropia:

  • Child’s parents are hypermetropic (long-sighted) and there is an inheritance factor
  • Child’ pre eye condition could be the contributing factor for Hypermetropia

Retinitis Pigmentosa and Microphthalmia are the two other factors which can influence hypermetropia. In the former case, Retinitis Pigmentosa is an eye disease wherein the retina gets eroded whereas in the latter case, Microphthalmia takes its genesis from hereditary syndrome.

Types of Hypermetropia

Hypermetropia can be classified into the following categories:

  • Congenital Hypermetropia – It is a very rare phenomenon occurring among the patients. It occurs due to an unusual short eye.
  • Simple Hypermetropia - This type of Hypermetropia can be widely seen. Usually, it is an extension of the childhood hypermetropia which has not retraced with time.
  • Acquired Hypermetropia - Acquired hypermetropia can crop up after injury or even by itself in certain disorders when the lens dislocates and slides backwards. Patients acquire the acquired Hypermetropia when they fall in the age range of 50-55.
