Visual development abnormalities in children aged 0to 10 years

Abstract

The human visual system goes through substantial changes during the first few months of postnatal life. The development of visual functions and structures occurs at different times and different rates. It has been a generally held belief that the development of visual functions and their critical period end early in life. Most of the developmental data confirm this theory, although the findings sometimes are contradictory. Psychophysical studies of children deprived of early visual experience by dense cataracts indicate that there are multiple sensitive periods during which experience can influence visual development. We note three sensitive periods within acuity, each with different developmental time courses: the period of visually-driven normal development, the sensitive period for damage, and the sensitive period for recovery. This thesis is made to answer the following clinical questions: What are the most common causes of visual developments abnormalities? what is the importance of the early detection of amblyopia? In view of the data in the literature and in our study, we found that the guarantors of good visual recovery are an early diagnosis and the early age of the patient in the beginning of the treatment, adherence to treatment and the cooperation of the child and his parents. Parents have a big role in the early detection of visual development disorders of their children Clinical examinations must be regular and systematic follow-up by an ophthalmologist or optometrist at least every year during the child's first decade.
