Absolute hyperopia is

• Part of hyperopia that cannot be corrected by accommodation

• Part of hyperopia that is corrected by the tone of the ciliary muscle

• Both parts of hyperopia that can and cannot be corrected by accommodation

• Part of hyperopia that can be corrected by accommodation

Degenerative myopia increase risk of

• Anterior uveitis

• Keratoconus

• Angle closure glaucoma

• Retinal detachment

Shallow anterior chamber is seen in

• High hypermetropia

• Astigmatism

Anisometropia means

• Difference in image sizes in the two eyes

• Both the eyes are not oriented in the same parallel axis

• Difference in pupil size

• There is high difference of refractive errors between the two eyes
