Fifteen percent of children have ophthalmic problems and the most frequent causes are
strabismus (4%), amblyopia (2%) and refractory problems. Amblyopia is the leading cause of
presentable loss of vision in developed countries. Amblyopia is a paediatric entity and most
vision loss from amblyopia is preventable or reversible with the right kind of intervention.
Early interventions are important to get good outcomes and late interventions cause very poor
recovery. Interventions beyond the critical periods of visual development cause long-term
irreversible vision loss.
The most important problems in the paediatric practice are insufficient time, insufficient
tools and lack of specific knowledge. Anyway, paediatric office is a very appropriate place for
visual testing in infants and children because paediatric skills and patience provide a confortable
atmosphere for these examinations. Furthermore, specific tests for infants and children
are basics for good collaboration.
We present our experience with two age-dependent tests for visual acuity. Lang test is
suitable for infants of nine months of age and older and Cambridge tests for children three
years of age and older.
