What is a latent hyperopia?

‘Latent’ hyperopia is a term used to describe the amount of farsightedness that is ‘masked’ when the accommodative muscles are used to increase the eye’s focusing power. Since children under 10 years of age have tremendous focusing ability. they can partially correct their farsightedness by focusing. or accommodating.

How do you determine latent hyperopia?

The standard test to discover if there is any latent hyperopia present is what is called a Cycloplegic Exam. A cycloplegic exam is fairly similar to a dilated fundus exam (yes… those terrible drops) only a little stronger.

What is pseudomyopia?

Pseudomyopia is an inappropriately excessive accommodation of the eye due to overstimulation or ciliary spasm, which leads to a marked approximation of the far point. Common symptoms of pseudomyopia include eye strain or fatigue, and it is classified as organic or functional.

What is Curvatural hypermetropia?

Curvature hypermetropia: Curvature hypermetropia is that condition in which curvature of the cornea, lens or both is increased (flatter) than the normal, resulting in change in refractive power of the eye. About 1 mm increase in radius of curvature results in 6 D of hypermetropia.

What are the different types of hyperopia?

There are three types of hyperopia: congenital hypermetropia, simple hypermetropia and acquired hypermetropia….Types of hyperopia

  • In congenital hypermetropia one eye is abnormally small.
  • Acquired hyperopia is a very common hyperopia.
  • Simple hyperopia is very common.

What is axial hypermetropia?

Axial hypermetropia: Axial hypermetropia is the commonest type. The total refractive power of the eye is normal but there is axial shortening of the eyeball. About 1 mm shortening of the antero-posterior length of the eye results in about 3 Dioptres (D) of hypermetropia.

Is hyperopia and hypermetropia the same?

Far-sightedness, also known as long-sightedness, hypermetropia, or hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred.

Is Pseudomyopia common?

It is common in young adults who have active accommodation, and classically occurs after a change in visual requirements, such as students preparing for an exam, or a change in occupation.

How common is latent hyperopia?

Overview. Farsightedness medically termed as hyperopia (hi-per-O-pe-ah) is a common condition that affects approximately 25 per cent of the adult population.
