'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.
What is latent and manifest Hypermetropia?
The manifest hyperopia is the sum of absolute and facultative hyperopia. Clinically, it is measured by the strongest plus (or convex) lens with which the patient can still maintain the maximum vision (20/20). Latent hyperopia is due to the inherent ciliary muscle tone.
What is manifest Hypermetropia?
Total hypermetropia after abolishing voluntary accommodation is known as manifest hypermetropia (facultative plus absolute). With advancing age, accommodative effort cannot be sustained, and hypermetropia becomes absolute till the effort of accommodation fails to correct any hypermetropia.
