Patient's question:
The hospital conducted tests. The machine showed 0.3 for the right eye and 1.0 for the left eye.Doctor's answer:
Physiological esotropia is a normal phenomenon. The development of the lateral rectus muscles in normal infants is slightly delayed compared to the medial rectus muscles, and their contractile function is slightly weaker than that of the medial rectus muscles. Therefore, if infants develop "crossed eyes," parents should not be overly anxious and should pay close attention. Generally, around the age of 2-3 years, as the lateral rectus muscles mature, this physiological esotropia will also correct itself. If the has not improved at this time, it should be taken seriously, and an ophthalmologist should be consulted.Strabismus: This refers to vision below 0.8, primarily caused by functional factors, with corrected vision failing to meet normal standards; or vision impairment and non-correctable eye diseases due to organic changes and refractive errors that do not match the severity of the condition. It can occur during any stage of visual development, starting as early as 1-2 years old, with earlier onset leading to more severe degrees. Strabismus is a delay or disruption in visual function development, often accompanied by, high refractive errors, etc., with corrected vision failing to reach normal levels. The best time for treating strabismus is between the ages of 1-5 during visual development.
