Vision defects
Amblyopia
What is amblyopia?
Amblyopia, or "lazy eye", is a gradual decrease in visual acuity due to a problem with either or both eyes' development during childhood.
There are two types of amblyopia:
passive amblyopia:
this is linked to ametropia, blurred vision which requires optical correction.
active amblyopia:
this is due to conflicting interpretations by the brain between the images from the right eye and the left eye. Causes are strabismus or anisometropia.
Correcting and treating amblyopia
It is possible to diagnose amblyopia from the age of six months via a full ophthalmological examination including objective refraction and ocular fundus. This enables the cause of the amblyopia to be identified.
In children
, treatment is based on full optical correction and covering of the healthy eye. This should occur before the age of six for the best results. The minimum treatment period is five years.
The only way of treating amblyopia
in adults
is full optical correction.
