Which condition is related to visual field defects due to optic nerve damage?

Cataracts
Glaucoma
Macular degeneration
Retinal detachment

The correct answer is: Glaucoma

Damage to the optic nerve can lead to visual field defects, where the person experiences loss of vision in certain areas of their visual field. Cataracts and macular degeneration may cause impairment of vision, but not specifically through optic nerve damage. Retinal detachment occurs when the thin layer of tissue at the back of the eye (retina) pulls away from the blood vessels that supply it with oxygen and nutrients, which can also lead to visual impairment. However, retinal detachment is not directly related to optic nerve damage. Glaucoma, on the other hand, is a group of eye conditions that can cause damage to the optic nerve, leading to visual field defects. Therefore, the only option related to visual field defects due to optic nerve damage is B Glaucoma.
