The goal of office testing of the child remains the same as it is for the adult--to gather as much information as efficiently as possible. Clinical testing of the child requires familiarity with the limitations available tests. Perhaps most important is the ability choose the proper test to use at every development stage. Cooperation may be surprisingly good in to hands of experienced examiners, though very young children can be unpredictable. The general ophthalmologist should not fear having young patients but rather take joy in the interaction with them. Armed with as many tools as possible, the challenge of testing children can be converted to the reward of helping families.
