The amblyopic eye has not developed vision correctly, but all eye structures are in good condition. Vision develops from birth, and the eye becomes increasingly more capable of perceiving objects, which is called visual acuity. The amblyopic eye does not develop visual acuity for various reasons. The eye is anatomically correct, i.e. its structures are normal, but vision has not developed.
When is an ocular occlusion used?
Ocular occlusion is used to make the diseased eye work harder by patching the healthy one, as in amblyopia. The intensity of the patching of the good eye to develop the vision of the amblyopic eye depends on the degree of vision and the age of the patient.
