What is it possible to detect?


Retinoblastoma are the most common eye tumor in children. Usually occur between six months and a year and a half old. Because children do not express vision loss, diagnosis several months or years later can be achieved, when it is too late to preserve the eye, even their lives are at risk.

Refractive Errors

They are changes in the way the eye focuses.

Vices of Refraction:

They are changes in the way the eye focuses.


A nearsighted person sees near objects clearly, but from a distance looks blurry. Myopia is a condition that occurs in people who have large diameter eyeballs or corneas excessive curvature. The fact squint tends to make distant objects appear sharper.


The images focus in theory behind the retina, and therefore near vision is blurred. It is because the diameter of the eyeball is smaller than normal or the cornea is too flat.
Most children are farsighted at birth (physiological hyperopia), a defect that is corrected as the eye develops.

If it does not and is not detected and treated early, can cause headaches and / or eyestrain.

Untreated childhood hyperopia can be cause of strabismus (misalignment of the eyes) and amblyopia (also called lazy eye). Farsightedness is easily corrected by using glasses or contact convergent.


In these cases, the cornea is abnormally curved, causing vision is blurred. Astigmatism makes it difficult to see fine details, either close or distant.
The cause of the astigmatism is unknown. It is usually present at birth and often occurs along with nearsightedness or farsightedness.

In children, the uncorrected astigmatism in only one eye may cause amblyopia (weakness or decrease in vision).

Treatment usually involves the use of eyeglasses or contact lenses.


It is the loss of parallelism between the eyes. This prevents gaze of both eyes at the same point in space, causing an incorrect binocular vision, which may adversely affect depth perception.

When strabismus is congenital or develops in infancy, it can cause amblyopia, a condition in which there is no proper development of neurological structures responsible for vision, why, when it comes to adulthood despite corrected pathology that led to amblyopia, amblyopic vision in that eye is insufficient and not corrected. Amblyopia is reversible during childhood and adolescence occasionally appropriate therapeutic measures, which in the case of strabismus usually patching therapy and eventually the use of lenses. In more severe cases, surgery is accessed.

 Leukocoria or white pupil in photographies: 

Could be the first sign of congenital cataract, Coats disease, retinoblastoma, retinopathy of prematurity, toxocariasis, Norrie disease, and retrolental fibroplasia
