A.     CHILDREN

A1. NEWLY BORNS
An eye check-up should be done at the very first days of birth at  the hospital by the obstetrician in charge. This check covers possibilities such as:

Leukokorea ( as in congenital cataract e. t. c.), eyelid fall (congenital fall - neuromyasthenia - hemageoma of the eyelid area - other mechanical causes e. t. c.), aniridia (lack of iris), congenital aphakia (lack of crystalline lens),  diseases of the eye fundus (Coat’s disease, retinal dysplasia, e. t. c.) nystagmus (involuntary motions of the eyeballs) e. t. c.
A2. INFANTS
Check for all the mentioned in A1 category plus check for possibilities such as:
Congenital glaucoma, diseases of the fundus (prematurely Retinopathy), strabismus.
Attention! In certain occasions (luckily the fewer ones) the cause of strabismus is anopsia (inability of sight) of one or both eyes. This could consist an urgent vision matter, urgent even for the life of the diseased.
A3. CHILDREN AGED  1 - 7 YEARS
Valid all the mentioned in categories A1 & A2 plus:

• Leukokorea of another cause such as retinoblastoma ( the most common primary intra-ocular malignant tumor at children), Coat’s disease, retinal astrokyttoma, retinal dysplasia e. t. c.
• Strabismus (often due to refractive abnormalities, easily corrected partially or fully by wearing eye glasses).
• Suspicion for refractive abnormalities. Often enough refractive abnormalities consider only one eye so the patient does not complain for sight inability because vision needs are covered by the healthy eye. This could lead the affected eye to amblyopia (lazy eye). Amblyopia is confronted by using eye glasses, coverage of the healthy eye e. t. c. and unfortunately can not be inverted after the first 7 years of age.

At the sensitive category A1 all children should have  a routine check of sight separately for each eye, by pediatricians, teachers and parents.
A4. CHILDREN AGED 7 - 13 YEARS
If  refractive or any other abnormality has been accredited, a child should have a steady attendance by the eye specialist (every 6 months - 1 year).

B.     ADOLESCENTS
Ophthalmologic examination (whether there is refractive abnormality every 1 -2 years). Sight self examination per eye (covering the eye not examined).
