About

Anisometropic amblyopia among children in school age may affects quality of life and educational progress of children.

Full description

Correction of anisometropic amblyopia depends on type of refractive error and axial length of the eye.

In this study, we will asses the types of anisometropia found in children at school age and investigate possible ways for correction of this type of amblyopia.

Enrollment: 200 estimated patients

Sex: All

Ages: 4 to 12 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Anisometropic amblyopia.
• Children at school age ranged from 4 to 12 years old.

Exclusion criteria

• Emmetropia children.
• Children had undergone any intraocular surgeries.
• Other types of amblyopia.

Trial design

200 participants in 4 patient groups
