The exception in first grade for phoria referral criteria acknowledges that children at this age are still developing visual skills, and some level of variability in eye alignment is normal. The criteria take this developmental aspect into account to prevent unnecessary referrals for further evaluation or treatment.
To maintain stereopsis and singleness of vision, the eye need to be pointed accurately.The position of each eye in its orbit is controlled by six extraocular muscles. Slight differences in the length or insertion position or strength of the same muscle in the two eyes can lead to a tendency for one eye to drift position in its orbit from the other, especially when one is tired. This is known as Phoria.
