Answer:
2. Crossed appearance of eyes
4. Impaired extraocular muscles
Explanation:
Strabismus is a disease from birth ( congenital condition) that affects the sight, when this happens it means both eyes can not focus on an object at the same time which results in the cross appearance of the eyes. This is a result of impaired extraocular muscles. Impaired near vision is related to hyperopia or presbyopia. Glaucoma occurs when there is elevated intra ocular pressure.
