3. Overview

Welcome from the Department for the Blind and Vision Impaired. This training is structured to give information on vision screening for infants and toddlers from 0 to 3 years of age. This is a 4 part training which will cover:

Behavioral Observations

Review of Observations of the Eye

Eye and Vision Screening Procedures

Resources


4. Behavioral Observations

Learning Objectives for Part 1:

1. Developmentally appropriate expectations from 0 to 3 months.

2. Developmentally appropriate expectations at 6 months.


5. Vision Development to 3 Months

Babies usually see movement before anything else, as their vision is still evolving. Full-term babies should be able to see their mother's facial expression within a week of birth.

Color vision is not yet fully developed at this time. Depth perception will also mature during the first year of life, as long as both of the child's eyes are working as a team.

Eye muscle coordination in a newborn, as well as a small child, is also very immature. Babies often exhibit eyes turned in, turned out or not working as a team, this should resolve itself by the age of 3 or 4 months.


6. Examples of Development

Birth to 6 weeks of age:

Stares at surroundings when awake

Momentarily holds gaze on bright light or bright object

Blinks at camera flash

Eyes and head move together

One eye may seem turned in at times

7. Examples of Development

8 weeks to 24 weeks:

Eyes begin to move more widely with less head movement

Eyes begin to follow moving objects or people (8-12 weeks)

Watches parent's face when being talked to (10-12 weeks)

Begins to watch own hands (12-16 weeks)

Eyes move in active inspection of surroundings (18-20 weeks)

While sitting, looks at hands, food, bottle (18-24 weeks)

Now looking for, and watching more distant objects (20-28 weeks)

8. 3 Months

Looks at someone's face and tracks with head and eyes


9. 3 Months

Pupil constricts at bright lights.


10. 3 Months

At 3 months the infant will observe different types of movement and light changes.

Observes movement in the room.


11. 3 Months

At 3 months the infant will observe different types of movement and light changes.

Watches own hands and feet.


12. 3 Months

At 3 months the infant will observe light changes.

Stares at light source


13. Vision Development at 6 Months

Between ages four and six months, a child should start to reach or bat at the mobile or toys you hold in front of him. Swatting a toy will happen by chance at first, then become deliberate as a child's vision, depth perception and understanding grows.


14. Examples of Development

30 weeks to 48 weeks of age:

May turn eyes inward while inspecting hands or toy (28-32 weeks)

Eyes more mobile and move with little head movement (30-36 weeks)

Watches activities around him for longer periods of time (30-36 weeks)

15. 6 Months

The developmental expectations at 6 months are:

Displays smooth following eye movements in all directions


16. 6 Months

Reaches for toys

Tracks movement

Shifts gaze between objects
