Chronic glaucoma can cause damage to which part of the eye?

1. Cornea

2. Lens

3. Ciliary body

4. Retina

The correct answer is: Ciliary body

Chronic glaucoma primarily affects the optic nerve, but it can also be related to changes in the ciliary body due to elevated intraocular pressure typical in this condition. The ciliary body is involved in the production of aqueous humor, which regulates intraocular pressure. In chronic glaucoma, the increased pressure can lead to structural changes and dysfunction in the ciliary body, affecting its ability to manage fluid dynamics within the eye. This can contribute to the progression of the disease and potential vision loss. The other parts of the eye listed, such as the cornea, lens, and retina, do not experience damage in the same direct manner related to chronic glaucoma. While secondary effects could potentially impact these structures due to prolonged elevated pressures or other complications, the ciliary body is the most directly affected by the pathophysiology of chronic glaucoma.
